Study questions benefit of taking fish oil
supplements during pregnancy

A new study questions the benefits of consuming fish oil sup-
plements during pregnancy. Doctors often recommend that
pregnant women take an Omega-3 acid, particularly DHA sup-
plement or fish oil, to optimize fetal brain and eye develop-
ment. Although there are 20 different edible fatty acids, the
human body cannot produce Omega-3 and Omega-6 fatty
acids, and most pregnant women are not likely to get enough
of these nutrients through their diets. A 2008 study published
in Obstetrics and Gynecology concluded that, along with vege-
table oils and two servings of seafood per week, women
should get these important Omega-3's from supplements.
Now, a research letter published Saturday in J AM A disputes
that recommendation. Researchers studied pregnant women
who were given an 800 mg DHA supplement or a placebo and
their children's brain development at age 4. The study found
prenatal DHA supplementation did not result in improved
cognitive, problem-solving, or language abilities for children at
age 4 (the children had been previously assessed at 18
months). They also observed that girls in the DHA group had
poorer language scores than girls in the control group. The
data collected from this study do not support recommenda-
tions of prenatal DHA supplementation to enhance early
childhood development. Link to original article: http://

Fish intake found to combat depression but
only in women

A new study suggests that eating fish at least twice a week re-
duces the risk of depression by 25 percent in women. This
study was developed by the Menzies Research Institute in Tas-
mania, Australia and was published in the American J ournal of
Epidemiology. The research concluded that the observed pro-
tective association for women and not for men may have been
due to men consuming more omega-3 fatty acids from other

(non-fish) dietary sources, primarily from meat. The study
tracked more than 1,400 men and women ages 26 to 36 for
a period of five years. The study speculates that high levels
of omega-3 fatty acids may combine with the female sex
hormones oestrogen and progesterone to keep the brain
functioning properly. Participants kept diaries of their diet,
including various types of seafood including fish, prawns,
and mussels consumed, while details about their mental
health were also collated. Dietitian Dr. Sarah Schenker
remarked that, "The fatty acids in fish are long chain so
[they] can be readily used by the body whereas they are
short chain in meat so have to be adapted. If men consume
more food but are more reliant on meat for their fatty acids
than women, it would perhaps explain why the positive
effects of fish on depression are seen only in women in this
study." Link to original article: http://www.fis.com/fis/

Coal ash spill - fish sampling to continue in
Dan River

The long-term effects of a February 2014 coal ash spill on
fish in the Dan River are still unknown, according to Vir-
ginia and North Carolina regulatory officials. This is pri-
marily because the incident at Duke Energy's old Dan Riv-
er Steam Station in Eden, NC, occurred in the winter dur-
ing a period when there was little biological activity by fish


-------
in the Dan River. The lack of fish activity hindered the
ability to monitor immediately following the spill to pick up
trace-element effects in the river's fish. The Virginia De-
partment of Environmental Quality (VDEQ) plans to con-
duct long-term monitoring of fish tissue at eight locations
along the Dan River from June through August over the
next three to five years. The VDEQ collected water and
sediment samples on February 11 at four sites along the
river nine days after the incident that caused 39,000 tons of
coal ash to enter the Dan River. The VDEQ tested the
water samples for 23 metals and those concentrations did
not exceed Virginia water quality standards. A preliminary
review of other Virginia water quality sample data collected
by the U.S. Environmental Protection Agency showed no
exceedances of standards. Tissue from 25 fish collected on
February 20 upstream of the Schoolfield Dam were tested
for 23 metals; arsenic concentrations were not elevated and
mercury concentrations were found to be below Virginia
Department of Health's level of concern. Despite metal
concentrations in fish tissue being within acceptable ranges,
it is still too early to determine to what extent the fish have
taken up the metals. The metals must first be liberated
from the ash and then enter the ecosystem to be taken up
by the fish. The VDEQ will provide information from
long-term monitoring to the Virginia Department of
Health to determine whether to issue a fish consumption
advisory. The Dan River, from Danville to Kerr Reservoir,
already has an advisory for polychlorinated biphenyls and
mercury that advises against consuming catfish more than
32 inches long and other fish more than twice a month.

Fish consumption advisories for pregnant
women ineffective in reducing infant
exposure to persistent organic pollutants

A new modeling study indicates that fish consumption ad-
visories for expecting mothers are ineffective in reducing
infant exposure to long-lived contaminants like persistent
organic pollutants (POPs). The study focused on how var-
ious levels of environmental contamination, a mother's
compliance with advisories, and the behavior of chemicals
in the body influenced exposure in her children. The re-
sults estimate that women who stop eating fish shortly be-

fore or during their pregnancy may only lower their child's
exposure to POPs by 10 to 15 percent. One of the re-
searchers believes that consumption advisories for POPs
are ineffective because they can remain in the body for
years or even decades due to properties that make it diffi-
cult for the human body to eliminate them. The same does
not apply for mercury-based advisories, as the residence
time of mercury in the body is shorter. Fish consumption
advisories are more effective for reducing exposure to
quickly eliminated contaminants like mercury. Link to

Fish in National Parks from Alaska to
Colorado have unhealthy mercury levels

A recent study has revealed high mercury levels in fish
within a number of national parks, from Alaska to Colora-
do. In some cases, the concentrations exceed limits ac-
ceptable for human consumption. One fish sample from
Yosemite National Park contained mercury at a concentra-
tion of 950 parts per billion (ppb), "at which no human
consumption is advised," according to the report produced
by the U.S. Geological Survey (USGS) and the National
Park Service (NPS). All 21 parks included in the four-year
survey contain fish with varying levels of mercury, ranging
in concentration from 9.9 ppb to 1,109 ppb, with an aver-
age concentration of 77.8 ppb. Fourteen of the 21 parks
surveyed did not contain any fish samples that exceeded
the 300 parts per billion EPA fish tissue criterion. While
only 5 percent of the nearly 1,500 fish sampled had mercu-
ry concentrations exceeding a benchmark of 200 parts per
billion that elicits toxic responses in fish, 35 percent of the
samples had mercury concentrations above 90 parts per
billion, high enough to impact some birds. In addition,
mercury levels in 68 percent of the fish "were above expo-
sure levels recommended by the Great Lakes Advisory
Group for unlimited consumption by humans," the study
said. The report notes that Zion, Capital Reef, Wrangell-
St. Elias, and Lake Clark national parks all contained sites
in which most fish exceeded benchmarks for the protec-
tion of human and wildlife health and that some fish sam-
ples taken within a single park varied widely in mercury
concentrations. A joint press release from the USGS and

Research into Noxon walleye fish
beginning

Montana Fish, Wildlife and Parks (FWP) says that biolo-
gists began to collect data starting in early April to deter-
mine population demographics, reproductive potential,
dietary habits, and polychlorinated biphenyl (PCB) concen-
trations within edible portions of walleye in the Noxon
Reservoir. State officials say the information will be used
in a revised draft Environmental Assessment and to deter-
mine if additional consumption advisories are necessary for
Noxon's sport fish. The goal of this short-term feasibility
study is to determine if the Noxon walleye population can
be effectively controlled, as a substantial amount of scien-
tific data indicates that walleye pose a threat to reservoirs'
fisheries, including perch and bass. Studies show that wall-
eye are efficient predators that feed on any species of fish
available and can quickly overpopulate, giving walleye the
ability to significantly reduce populations of other fish spe-
cies. Link to original article: http://www.kpax.com/

State issues new fish consumption
advisories

The 2014 West Virginia Sport Fish Consumption Advisory
has updated its advisories for eating fish caught in lakes
and rivers. This advisory revision removes limits on con-
sumption of Greenbrier River smallmouth bass and walleye
from Summersville Lake. The West Virginia Department
of Health and Human Resources explained that newer in-
formation indicates lower mercury levels in both fish spe-
cies at these locations. However, a limit on consumption
of smallmouth bass from the Shenandoah River was ex-
panded to include all fish sizes, while the previous limit
only applied to fish greater than 12 inches in length. New

State warns certain Monterey Bay seafoods
may be temporarily unsafe to eat

The California Department of Public Health (CDPH)
warned the public of a naturally occurring toxin that is
showing up in seafood recently caught in Monterey Bay.
According to a recent press release, unsafe levels of domoic
acid, produced by algae blooms, have been detected in an-
chovy, sardines, and the internal organs of crab caught off
the shores of Monterey and Santa Cruz counties. Anchovy
and sardines are of concern because the toxin resides in
their digestive tracks and these fish are not usually gutted
before they are eaten. CDPH is coordinating with com-
mercial fishermen in the area to ensure that recendy caught
sardines, anchovies, and crab were not distributed into the
human food supply. CDPH has also warned consumers to
avoid bivalves including mussels, clams, and whole scallops
harvested by recreational fishermen in Monterey Bay.
However, commercially sold bivalves from approved
sources are exempt from the advisory because they are test-
ed for toxins. While no related illnesses have been report-
ed, the state continues to monitor domoic acid levels in the
area's seafood. For more information and updates, call
(800) 553-4133 or visit CDPH's Natural Marine Toxins

Mercury level concerns prompt Flathead
Lake fish guidelines

Trout, in Flathead Lake contain trace amounts of mercury,
therefore the Confederated Salish and Kootenai Tribes
(CSKT) and Montana Fish, Wildlife and Parks (FWP) have
partnered to issue guidelines for safe consumption of the
fish. Lake trout are predators in Flathead Lake, and are
more likely to accumulate mercury. CSKT Information
and Education Specialist, Germaine White, says that the
size of the fish is what really matters. CKST created a
guideline for safe consumption, advising children and
women of childbearing age to eat no more than six serv-
ings a month of lake trout 6 to 10 inches long. Adult males
can eat up to 12 servings a month of the smaller fish.

While eating Flathead Lake trout is safe, the guidelines rec-
ommend against eating lake trout longer than 30". For a
complete guide on safe lake trout consumption: http://

Occurrence of di-(2-ethylhexyl) adipate
and phthalate plasticizers in samples of
meat, fish, and cheese and their packaging
films

Di-(2-ethylhexyl) adipate (DEHA) and phthalates are com-
monly used as plasticizers to soften polyvinyl chloride
products. Because both DEHA and certain phthalates
have been identified as priority chemicals for assessment of
human health risk under the Government of Canada's
Chemicals Management Plan, a comprehensive targeted
survey was conducted to investigate the occurrence of


-------
DEHA and eight phthalates (di-methyl phthalate, di-ethyl
phthalate, di-n-butyl phthalate, di-iso-butyl phthalate, butyl
benzyl phthalate, di-n-hexyl phthalate, d-(2-ethylhexyl)
phthalate, and di-n-octyl phthalate) in a total of 118 sam-
ples of meat (beef, pork, and chicken), fish, and cheese
packaged mostly in cling films. The eight phthalates were
not detected in any of the food packaging, but DEHA was
detected in most of the cling films, indicating that although
DEHA-plasticized films (e.g., polyvinyl chloride film) are
currently being used by most grocery stores, nonplasticized
cling films such as polyethylene film, are also being used by
some stores. DEHA was not detected in any of the 10
cheese samples packaged in nonplasticized rigid plastics but
was detected in all 30 cheese samples packaged in DEHA-
plasticized cling films at levels from 0.71 to 879 [xg/g, with
an average of 203 [xg/g. Only DEHA was detected in the
beef, pork, chicken, and fish samples packaged in DEHA-
plasticized cling films but at considerably lower levels than
those found in cheese, with averages of 6.3, 9.1,2.5, and
5.9 fig/g, respectively. Among the eight phthalates, only di
-(2-ethylhexyl) phthalate (DEHP) was detected in a few
cheese samples at levels from 0.29 to 15 [xg/g, with an av-
erage of 2.8 [xg/g; these levels were very likely due to envi-
ronmental contamination. Levels of DEHA found in most
of the cheese samples from this study are above the Euro-
pean specific migration limit of 18 mg/kg for DEHA in
food or food simulants, and levels of phthalates (i.e.,
DEHP) were low.

Heavy metals levels in fish from aquacul-
ture farms and risk assessment in Lhasa,
Tibetan Autonomous Region of China

Fish is consumed as a common food by humans due to its
nutritional and therapeutic benefits. However, they can
accumulate toxic chemicals (such as heavy metals, persis-
tent organic pollutants) from water and food chain. Very
few studies have been investigated on heavy metal contents
in fish from Tibetan Autonomous Region of China. In
order to study heavy metals levels in fish from aquaculture
farms and evaluate the risk that humans consume fish in
this area, we collected four types of aquaculture fish species
(6 big-head carps, 5 grass carps, 5 carps and 5 tilapias) from

fisheries around Lhasa city in this study. 9 heavy metals
(Cr, As, Cd, Pb, Cu, Ba, Co, Mn and V) in different tissues
of fish were determined by an inductively coupled plasma
mass spectrometer. Cr, Ba, Co, Mn and V could easily ac-
cumulate in the gill, and Cu was detected in the hearts of all
the fishes. Toxic metal (As, Cd and Pb) contents were
higher in the liver than those in other tissues, heavy metal
levels were the lowest in the muscle among all tissues.

Most of heavy metal concentrations in the tilapia tissues
were higher than those in other fish tissues, especially arse-
nic. Arsenic content in the tilapia samples was ~2-4 times
higher than the maximum levels (MLs) of contaminants in
the national standard, and other metals were all lower than
the MLs. Compared the estimated daily intake of heavy
metals through fish consumption with tolerable daily in-
takes recommended by FAO, the metals daily intake of As,
Cd and Pb from fish consumption might not pose serious
health risk to the local inhabitants. It is therefore necessary
to determine the dose level for human, which is considered
to be taken daily over a lifetime without adverse effects.

Human health risks of geothermally
derived metals and other contaminants in
wild-caught food

Arsenic (As) and mercury (Hg) associated with geothermal-
ly influenced lakes and rivers represent a potential health
risk to communities where wild-caught food is consumed.
The Rotorua Lakes region of New Zealand has extensive
natural geothermal activity and a large proportion (35%) of
indigenous Maori population, for whom wild food gather-
ing is an important cultural activity. The aim of this study
was to measure selected heavy metal and organochlorine
(OC) concentrations in important local fish and shellfish
species and assess the potential health risk to the local pop-
ulation of consuming these species. Following U.S. Envi-
ronmental Protection Agency (EPA) protocols, consump-
tion limits were calculated based on both excess lifetime
cancer risk and noncancer risk. These were compared with
local consumption rates, which were determined by ques-
tionnaire (n = 19). Median and 95th percentile contami-
nant concentrations were calculated to approximate ran-

dom and most extreme contaminant consumption scenari-
os. Only Hg concentrations exceeded established Food
Standards Australia New Zealand (FSANZ) guideline val-
ues of 0.5 mg/kg, namely, for rainbow trout (Oncorhjnchus
mykiss; 62% of the study sites) and koura (freshwater cray-
fish; Paranephropsplanifrons\ 25% of sites). The major risk
was from consumption of trout, where the local consump-
tion rate (1.5 meals/mo) exceeded the consumption limit
of 0.9 meals/mo (median data) and 0.4 meals/mo (95th
percentile data). Shellfish—pipi (Paphies australis) and mussel
(Perna canaliculus)—collected from the only estuarine site also
had local consumption rates (3.5 meals/mo) above calcu-
lated consumption limits (2.6 and 2.9 meals/mo, respec-
tively). Our results, while based on a limited sample size
and therefore exploratory in nature, nevertheless provide
the basis for developing consumption guidelines. This
study makes a significant contribution to broadening our
understanding of the complexities of managing customary
fisheries.

Exposure assessment of pregnant Portu-
guese women to methylmercury through
the ingestion of fish: cross-sectional survey
and biomarker validation

Methylmercury (MeHg) contamination is a critical public
health problem in Portugal, where fish is an important
component of the daily diet. The Portuguese are the third
largest consumers in the world (after Japan and Iceland)
but first in Europe. Prenatal exposure to MeHg is believed
to be linked to fetal/child neurodevelopment and behav-
ioral impairments due to the neurotoxicity of the com-
pound. The objective of this study was to assess the expo-
sure of pregnant Portuguese women to mercury (Hg) due
to fish consumption, calculating the indices of risk and
confirming exposure through analyses of a biomarker of
exposure. The study consisted of a cross-sectional evalua-
tion of 343 pregnant women recruited at their visit to two
antenatal care units in Lisbon, Portugal. A food frequency
questionnaire was used to estimate prenatal exposure. To-
tal Hg levels in hair were analyzed by atomic absorption, in
samples from 186 women. The average fish consumption
was 3.1 meals per week. Median Hg level in the hair was

1.26 [ig/g (range: 0.07-5.3 p-g/g). The mean calculated risk
index was 0.81; however, 28% of the pregnant women in-
gested levels above the provisional tolerable weekly intake
(PTWI) level recommended by the World Health Organi-
zation (WHO; 1.6 mg/kg per body weight), indicating the
possibility of risk due to MeHg exposure. Multiple linear
regression analysis showed the risk index was reliably pre-
dicted from predatory fish species and number of fish
meals consumed per week. Ingestion of black and silver
scabbard fish as well as mixed predatory fish cooked in
traditional dishes enhanced the toxicity risk. In conclusion,
some exposure levels exceeded the reference value; there-
fore, nutritional counseling needs to be provided to popu-
lations at risk.

Children's health risk and benefits offish
consumption: risk indices based on a diet
diary follow-up of two weeks

Several epidemiological studies indicate that fish intake is
associated with neurocognitive development and visual
outcomes in children attributed to long-chain polyunsatu-
rated fatty acids (PUFA). However, methylmercury
(MeHg) represents the most toxic and abundant form of
environmental mercury (Hg) exposure to humans and ex-
posure occurs primarily through fish consumption. The
objective of the study was to describe fish consumption
during childhood in Portugal, estimating the intake of Hg
from fish and calculating the indices of risk. The group
consisted of 233 infants and students aged 7-11 yr and at-
tending 5 primary schools in Lisbon, Amadora, and
Sesimbra. Information regarding food consumption habits
was collected through a food diary during 2 weeks, com-
pleted under the supervision of teachers and parents, where
participants registered what was ingested for lunch and
dinner during that period. The exposure assessment and
indices of risk were calculated for each participant. Indi-
viduals were classified according to weekly intake and indi-
ces of risk determined per group. In addition, the methods
used to collect information on fish intake habits, a food
frequency questionnaire and diet diary, are described in
relation to quality of information provided. The mean val-

6	July 2014


-------
ue of fish meals per week was approximately 5. The calcu-
lated indices of risk reached values above 1 in more than
50% of the studied population, demonstrating the presence
of risk in subsets of the population. While Portuguese chil-
dren represent an important group of fish consumers, this
does not manifest as appreciable benefit with respect to
omega-3 ingestion, as children ingest half or less of the
recommended value (200 mg/d of omega-3), which is
equivalent to being exposed to risk for Hg intoxication.
The choice of fish species shows lack of knowledge of fish
characteristics. Therefore, risk communication and popula-
tion education need to be established to prevent consump-
tion of predatory fish species that contribute to the in-
crease in risk toxicity and to encourage ingestion of prey
fish, which represent significant levels of high-value nutri-
ents such as PUFA.

Hazard assessment of metals in invasive
fish species of the Yamuna River, India in
relation to bioaccumulation factor and
exposure concentration for human health
implications

Monitoring of heavy metals was conducted in the Yamuna
River considering bioaccumulation factor, exposure con-
centration, and human health implications which showed
contamination levels of copper (Cu), lead (Pb), nickel (Ni),
and chromium (Cr) and their dispersion patterns along the
river. Largest concentration of Pb in river water was 392
fig L(-l); Cu was 392 pig L(-l) at the extreme downstream,

Allahabad and Ni was 146 jxg L(-l) at midstream, Agra.
Largest concentration of Cu was 617 fig kg(-l), Ni 1,621 pig
kg(-l) at midstream while Pb was 1,214 pig kg(-l) at Allaha-
bad in surface sediment. The bioconcentration of Cu, Pb,
Ni, and Cr was observed where the largest accumulation of
Pb was 2.29 fig kg(-l) in Oreochromis niloticus and 1.55 pig kg
(-1) in Cyprinus carpio invaded at Allahabad while largest
concentration of Ni was 174 pig kg(-l) in 0. niloticus and
124 pig kg(~l) in C. carpio in the midstream of the river.
The calculated values of hazard index (HI) for Pb was
found more than one which indicated human health con-
cern. Carcinogenic risk value for Ni was again high i.e.,
17.02 X 10(-4) which was larger than all other metals stud-
ied. The results of this study indicated bioconcentration in
fish due to their exposures to heavy metals from different
routes which had human health risk implications. Thus,
regular environmental monitoring of heavy metal contami-
nation in fish is advocated for assessing food safety since
health risk may be associated with the consumption of fish
contaminated through exposure to a degraded environ-
ment.

Fish intake during pregnancy, fetal growth,
and gestational length in 19 European birth
cohort studies

B ACKGROUND: Fish is a rich source of essential nutri-
ents for fetal development, but in contrast, it is also a well-
known route of exposure to environmental pollutants.
OBJECTIVE: We assessed whether fish intake during
pregnancy is associated with fetal growth and the length of
gestation in a panel of European birth cohort studies. DE-
SIGN: The study sample of 151,880 mother-child pairs
was derived from 19 population-based European birth co-
hort studies. Individual data from cohorts were pooled
and harmonized. Adjusted cohort-specific effect estimates
were combined by using a random- and fixed-effects meta-
analysis. RESULTS: Women who ate fish >1 time/wk
during pregnancy had lower risk of preterm birth than did
women who rarely ate fish (< 1 time/wk); the adjusted RR
of fish intake >1 but <3 times/wk was 0.87 (95% CI: 0.82,

National Listing of Fish Advisories 7


-------
0.92), and for intake > 3 times/wk, the adjusted RR was
0.89 (95% CI: 0.84, 0.96). Women with a higher intake of
fish during pregnancy gave birth to neonates with a higher
birth weight by 8.9 g (95% CI: 3.3,14.6 g) for >1 but <3
times/wk and 15.2 g (95% CI: 8.9,21.5 g) for > 3 times/
wk independent of gestational age. The association was
greater in smokers and in overweight or obese women.
Findings were consistent across cohorts. CONCLUSION:
This large, international study indicates that moderate fish
intake during pregnancy is associated with lower risk of
preterm birth and a small but significant increase in birth
weight.

Temporal and spatial trends in freshwater
fish tissue mercury concentrations associ-
ated with mercury emissions reductions

Mercury (Hg) concentrations were monitored from 1999 to
2011 in largemouth bass (LMB) and yellow perch (YP) in
23 lakes in Massachusetts USA during a period of signifi-
cant local and regional Hg emissions reductions. Average
LMB tissue Hg concentration decreases of 44% were seen
in 13 of 16 lakes in a regional Hg "hotspot" area. YP in all
lakes sampled in this area decreased 43% after the major
emissions reductions. Comparative decreases throughout
the remainder of the state were 13% and 19% for LMB and
YP respectively. Annual tissue mercury concentration rate
decreases were 0.029 (LMB) and 0.016 mg Hg/kg/yr (YP)
in the hotspot. In lakes around the rest of the state, LMB
showed no trend and YP Hg decreased 0.0068 mg Hg/kg/
yr. Mercury emissions from major point sources in the
hotspot area decreased 98%, and 93% in the rest of the
state from the early 1990s to 2008. The significant declines
in fish Hg concentrations in many lakes occurred over the
second half of a two decade decrease in Hg emissions pri-
marily from municipal solid waste combustors and, second-
arily, from other combustion point sources. In addition to
the substantial Hg emissions reductions achieved in Massa-

chusetts, further regional, national and global emissions
reductions are needed for fish Hg levels to decrease below
fish consumption advisory levels.

Milestone achievement and neurodevelop-
ment of rural Amazonian toddlers (12 to
24 months) with different methylmercury
and ethylmercury exposure

Neurological outcomes (Gesell development schedules
[GDS]), age of walking, and age of talking were studied in
299 toddlers (12 to 24 mo) in relation to environmental
(fish consumption and tin mining) exposure. Exposure to
fish methylmercury (MeHg) consumption and iatrogenic
ethylmercury (EtHg) in Thimerosal-containing vaccines
(TCV) was quantified in toddlers from two rural villages (n
= 91, Itapua; n = 218, Bom Futuro) respectively populated
by fishers and cassiterite miners. Median total hair Hg
(HHg) concentrations of infants from Itapua (3.5 jig/g)
were significantly higher than those of infants from Bom
Futuro (2.2 [xg/g). Median EtHg exposure from TCV was
also significantly higher in toddlers from Itapua (137.5 p.g)
than in those from Bom Futuro (112.5 pig). There were no
significant differences between groups for any of the Gesell
schedules; however, there were proportionally more com-
promised toddlers (GDS < 70) in Itapua than Bom Futuro.
Median age of talking was not statistically different but me-
dian age of walking was significantly higher in Bom Futuro.
In toddlers from both villages, of fishers and miners, HHg
concentrations were significantly correlated with family fish
consumption. A logistic regression model was applied to
all infants after classification into two groups: above or
below the median Gesell schedules. Overall, there was no
distinctive pattern of neurodevelopment associated with
either HHg or EtHg exposure; however, nutritional status
was significantly associated with GDS. In conclusion,
milestone achievement was delayed in toddlers from tin-
ore mining communities. Despite significantly higher ex-
posure to both forms of organic Hg (MeHg from maternal
fish consumption, and EtHg from TCV) in toddlers from
the fishing village, significant differences were seen only

Pre-anthropocene mercury residues in
North American freshwater fish

Mercury (Hg) has been entering the environment from
both natural and anthropogenic sources for millennia, and
humans have been influencing its environmental transport
and fate from well before the Industrial Revolution. Expo-
sure to Hg (as neurotoxic monomethylmercury [MeHg])
occurs primarily through consumption of finfish, shellfish,
and marine mammals, and regulatory limits for MeHg con-
centrations in fish tissue have steadily decreased as infor-
mation on its health impacts has become available. These
facts prompted us to consider 2 questions: 1) What might
the MeHg levels in fish tissue have been in the pre-
Anthropocene, before significant human impacts on the
environment? and 2) How would these pre-Anthropocene
levels have compared with current regulatory criteria for
MeHg residues in fish tissue? We addressed the first ques-
tion by estimating pre-Anthropocene concentrations of
MeHg in the tissues of prey and predatory fish with an in-
tegrated Hg speciation, transport, fate, and food web mod-
el (SERAFM), using estimated Hg concentrations in soil,
sediment, and atmospheric deposition before the onset of
significant human activity (i.e., <2000 BCE). Model results
show MeHg residues in fish varying depending on the
characteristics of the modeled water body, which suggests

that Hg in fish tissue is best considered at the scale of indi-
vidual watersheds or water bodies. We addressed the sec-
ond question by comparing these model estimates with
current regulatory criteria and found that MeHg residues in
predatory (but not prey) fish could have approached or
exceeded these criteria in some water bodies during the pre
-Anthropocene. This suggests that the possibility of natu-
rally occurring levels of Hg in fish below which it is not
possible to descend, regardless of where those levels stand
with respect to current regulatory limits. Risk management
decisions made under these circumstances have the poten-
tial to be ineffectual, frustrating, and costly for decision
makers and stakeholders alike, suggesting the need for reg-
ulatory flexibility when addressing the issue of Hg in fish.

Mercury exposure in pregnancy: a review

Mercury exposure in pregnancy has been associated with
both pregnancy complications and developmental prob-
lems in infants. Apart from industrial accidents and con-
taminated food, mercury exposure is likely to arise from
predatory fish consumption, environmental contamination
and dental amalgam restorations placed before or during
pregnancy. It would be prudent to recommend that preg-
nant women avoid these potential problems and minimize
any risk. The available literature indicates a linear relation-
ship with mercury levels and IQ deficit, and therefore a
safe limit of mercury cannot be calculated.

Gestational weight gain and exposure of
newborns to persistent organic pollutants

BACKGROUND: Exposure to persistent organic pollu-
tants (POPs) during fetal development can increase the risk
of adverse health effects during childhood. Maternal char-
acteristics and physiological changes during gestation such
as gestational weight gain (GWG) may have an influence in
the overall burden of POPs in neonates. However, the
associations between GWG and POP concentrations are
still not well established. OBJECTIVE: We examined the
association of GWG with cord serum POPs concentrations
after adjusting for pre-pregnancy maternal body mass index

-------
(BMI) and other potential determinants of the transfer of
POPs into newborns. The GWG values were evaluated
after grouping by the reference guidelines of the Institute
of Medicine (IOM). METHODS: We measured levels of
14 organochlorine pesticides, 7 polychlorobiphenyls
(PCBs) and 14 polybromodiphenyl ethers (PBDEs) in 325
cord serum samples from a Spanish birth cohort. Multivar-
iable models were used to estimate associations of GWG,
pre-pregnancy BMI, and other maternal determinants on
cord serum concentrations of POPs. RESULTS: Neonatal
concentrations of POPs were inversely associated with
GWG after adjustment for age, pre-pregnancy BMI, educa-
tional level, and fish consumption. On average, neonates
of women with IOM recommended GWG have lower
POP concentrations than neonates of mothers with inade-
quate GWG. CONCLUSIONS: The present findings
suggest an association between neonatal exposure to POPs
and inadequate GWG during pregnancy. Encouraging
pregnant women to meet the recommended IOM guide-
lines for GWG may reduce the accumulation of POPs in
newborns.

Comparison of seafood consumption in a
group of Italian mother-child pairs

Seafood is an important component of healthful human
diets. Intake of seafood is recommended both for young
women and children. In fact, it is a good source of high-
quality protein, low in saturated fats, and rich in essential
nutrients (e.g. iodine, iron, choline, and selenium) and long-
chain polyunsaturated fatty acids (LCPUFAs), especially
omega-3. However, the relationship between maternal diet
and the children's dietary habits is controversial. This study
investigated the possible association between the seafood
consumption by mothers and that by their 8-11 years old
children and compared maternal seafood intakes during
pregnancy and about 10 years later. The seafood consump-
tion by 37 pregnant women was assessed in 1999-2001. In
2009, mothers were asked to report their weekly intake and

their children's. Mother-child pairs showed a similar con-
sumption pattern: the overall intake was 1.28 +/- 0.77 ver-
sus 1.19 +/- 0.64 (p = 0.49) while the sum of specific items
was 3.71 +/- 3.01 versus 3.18 +/- 2.90 (p = 0.049). How-
ever, it cannot be discerned whether maternal diet affected
the children's nutritional habits or vice-versa. In fact,
mothers showed to have a higher seafood intake about 10
years after pregnancy (3.71 versus 1.83; p < 0.001), suggest-
ing that a progressive modification of dietary habits oc-
curred after delivery, possibly due to the influence of ma-
ternal diet on the nutritional habits of offspring or due to
the presence of children in the family unit, that could have
influenced maternal dietary habits. This dietary improve-
ment could be brought forward through educational inter-
ventions addressed to young women, that could also allow
a more informed choice of the healthier species of fish
both for them and their children.

Food sources of arsenic in pregnant
Mediterranean women with high urine
concentrations of this metalloid

Seafood consumption provides a significant amount of
arsenic, although in its organic, nontoxic forms. Mediterra-
nean populations may incorporate high levels of this metal-
loid as a consequence of seafood consumption. In the pre-
sent study, the significance of this input among pregnant
women from a Mediterranean city (Sabadell, Catalonia,
Spain) is assessed. Total urinary arsenic was analyzed in
489 pairs of urine samples, corresponding to the 12th and
32th weeks of pregnancy. Association of arsenic content
with seafood and other dietary items were studied. Geo-
metric mean concentrations were 34 and 37 |xg/g creatinine
during the first and third trimesters, respectively. The ob-
served concentrations were similar to those reported in
studies from other Mediterranean countries. The differ-
ences between both periods were not statistically signifi-
cant. The only dietary factor significantly and positively
associated with total urinary arsenic in both series of sam-
ples was seafood, particularly lean fish. Moreover, lean fish
consumption during both periods was found to be the
main determinant for differences in levels of arsenic be-
tween the first and third trimesters, which confirms the
association between high levels of total urinary arsenic and
seafood consumption.

Dietary effects of introducing school meals
based on the New Nordic Diet - a
randomised controlled trial in Danish
children.The OPUS School Meal Study.

The OPUS (Optimal well-being, development and health
for Danish children through a healthy New Nordic Diet
(NND)) School Meal Study investigated the effects on the
intake of foods and nutrients of introducing school meals
based on the principles of the NND covering lunch and all
snacks during the school day in a cluster-randomised cross-
over design. For two 3-month periods, 834 Danish children
aged 8-11 years from forty-six school classes at nine
schools received NND school meals or their usual packed

lunches brought from home (control) in random order.
The whole diet of the children was recorded over seven
consecutive days using a validated Web-based Dietary As-
sessment Software for Children. The NND resulted in
higher intakes of potatoes (130 %, 95 % CI 2-07, 2-58),
fish (48 %, 95 % CI 1 -33,1-65), cheese (25 %, 95 % CI
MS, 1-36), vegetables (16 %, 95 % CI MO, 1-21), eggs (10
%, 95 % CI 1 -01,1 ¦ 19) and beverages (6 %, 95 % CI 1 -02,
1-09), and lower intakes of bread (13 %, 95 % CI 0*84,

0-89)	and fats (6 %, 95 % CI 0-90, 0-98) were found
among the children during the NND period than in the
control period (all, P< 0'05). No difference was found in
mean energy intake (P= 0'4), but on average children re-
ported 0-9 % less energy intake from fat and 0-9 % higher
energy intake from protein during the NND period than in
the control period. For micronutrient intakes, the largest
differences were found for vitamin D (42 %, 95 % CI 1-32,

1-53)	and iodine (11 %, 95 % CI 1-08,1-15) due to the
higher fish intake. In conclusion, the present study showed
that the overall dietary intake at the food and nutrient lev-
els was improved among children aged 8-11 years when
their habitual packed lunches were replaced by school
meals following the principles of the NND.

Fish consumption and lung cancer risk:
systematic review and meta-analysis

There is evidence pointing to a possible role of diet on can-
cer etiology. Prior studies evaluating the relationship be-
tween fish consumption and lung cancer risk reported in-
conclusive results. The aim of this study was to achieve a
comprehensive assessment of the relationship between fish
consumption and lung cancer risk through systematic re-
view and meta-analysis. Case control and cohort studies up
to September 1,2012 about fish consumption and lung
cancer risk were confirmed by an online search. Separate
relative risk (RR) or odds ratio (OR) estimates with 95%
confidence interval (CI) of the relationship between lung
cancer risk and fish consumption level from the included
articles were combined by Statall.O software. Publication
bias was evaluated by Egger's linear regression test and
funnel plot. Twenty articles (17 case-control and 3 cohort
studies) comprising 8799 cases of lung cancer and 17,072
noncases were included in the final analysis. The pooled
results from all studies indicated that high fish consump-
tion was significantly associated with a decreased risk of
lung cancer (pooled RR: 0.79; 95% CI: 0.69-0.92). There
was heterogeneity among the studies (1(2) = 73%, P <
0.05). Pooled RR in case control and cohort studies were
0.76 (95% CI: 0.63-0.91) and 0.95 (95% CI: 0.73-1.24), re-
spectively. Omission of any single study had little effect on
the combined risk estimates. This article had no publica-
tion bias. This study identifies a significant association
between fish consumption and lung cancer, confirming a
protective role of fish in lung cancer. More well-designed
prospective studies are required to further verify the effect
of fish consumption on lung cancer.

Influence of feeding graded levels of canned
sardines on the inflammatory markers and
tissue fatty acid composition ofWistar rats

Canned sardines are a ready-to-use fish product with excel-
lent nutritional properties owing to its high n-3 long-chain
PUFA content, mainly EPA (20 : 5n-3) and DHA (22 : 6n-
3). The present study aimed to assess the effect of two
dosages of canned sardines, recommended for the primary
and secondary prevention of human CVD, on the inflam-

matory marker concentrations and fatty acid composition
of erythrocytes and key metabolic tissues (Uver, muscle,
adipose tissue and brain) in the rat model. Wistar rats were
fed a diet containing 11 % (w/w) of canned sardines (low-
sardine (LS) diet) and a diet containing 22 % (w/w) of
canned sardines (high-sardine (US) diet) for 10 weeks.

Daily food intake, weight gain, and organ and final body
weights were not affected by the dietary treatments. The
concentrations of total cholesterol, HDL-cholesterol and
LDL-cholesterol decreased in both the LS and HS groups,
while those of alanine aminotransferase and adiponectin
increased. The concentrations of IL-lp increased only with
the highest dosage of sardine. The dose-dependent influ-
ence of the graded levels of EPA+DHA was tissue specif-
ic. Compared with that of other tissues and erythrocytes,
the fatty acid composition of the brain was less affected by
the canned sardine-supplemented diets. In contrast, the
retroperitoneal adipose tissue was highly responsive. The
deposition ratios of EPA and DHA indicated that the LS
diet was optimal for DHA deposition across the tissues,
except in the retroperitoneal adipose tissue. Taken togeth-
er, our findings indicate that a LS diet positively affects
plasma lipid profiles and inflammatory mediators, whereas
a HS diet has contradictory effects on IL~1|3, which, in
turn, is not associated with variations in the concentrations
of other pro-inflammatory cytokines. This finding requires
further investigation and pathophysiological understanding.

Impact of Omega-3 and Omega-9 fatty ac-
ids enriched total parenteral nutrition on
blood chemistry and inflammatory markers
in septic patients

Objective: Lipid emulsions containing omega-3 are known
to have positive effects on patient's prognosis due to anti-
inflammatory properties. The aim of this study was to in-
vestigate the effects of omega-3 enriched total parenteral
nutrition (TPN) emulsion containing omega-9 on biochem-
ical parameters, inflammatory mediators in septic patients.
Methods: Thirty-two participants who were not fed orally
for over five days and needing TPN support were included
in this prospective, randomized and double-blind clinical
study. Patients were randomly divided into control (n=16),
treatment (n=16) groups. The treatment group received
TPN containing 80% olive oil+20% soy oil additionally 10
g fish oil enriched TPN. Control group received only olive
oil containing standard lipid emulsion (1.3+0.1 g/kg/day).
Blood samples were collected for biochemical analysis on
the l(st) and 6(th) days of study. Results: The serum albu-
min levels significantly increased (p<0.05) in both groups
whereas total protein and prealbumin levels did not show
any significant changes. In treatment group, significant
decreases were determined in LTB4 and CRP levels
(p<0.05) while decreases in IL-6, TNF-oc and leukocyte
levels were not significant. No statistically significant
changes were found in LTB4, CRP, IL-6, TNF-a and leu-
kocyte levels of controls. Conclusion: Results of the study
have shown that omega-3 enriched TPN solution contain-
ing omega-9 contributes to decrease in the levels of inflam-

matory mediators and to improvement in the biochemical
parameters in septic patients.

Longitudinal associations between fish con-
sumption and depression in young adults

Few studies have examined longitudinal associations be-
tween fish consumption and depression; none have defined
depression using a diagnostic tool. We investigated wheth-
er fish consumption was associated with fewer new depres-
sion episodes in a national study of Australian adults. In
2004-2006,1,386 adults aged 26-36 years (38% males)
completed a 127-item (9 fish items) food frequency ques-
tionnaire. Fish intake was examined continuously (times/
week) and dichotomously (reference group: <2 times/
week). During 2009-2011, the lifetime version of the Com-
posite International Diagnostic Interview was administered
by telephone. New episodes of major depression/
dysthymic disorder (since baseline) were defined using the
Diagnostic and Statistical Manual of Mental Disorders,
Fourth Edition. During follow-up, 160 (18.8%) women
and 70 (13.1%) men experienced depression. For women,
each additional weeldy serving of fish consumed at baseline
decreased the risk of having a new depressive episode by
6% (adjusted relative risk = 0.94, 95% confidence interval:
0.87,1.01). Women who ate fish >2 times/week at base-
line had a 25% lower risk of depression during follow-up
than those who ate fish <2 times/week (adjusted relative
risk = 0.75, 95% confidence interval: 0.57, 0.99). Reverse
causation was also suggested but appeared to be restricted
to persons with recent depression. Fish consumption was
not associated with depression in men. These findings
provide further evidence that fish consumption may be
beneficial for women's mental health.

Omega-3 fatty acids and depression: scien-
tific evidence and biological mechanisms

The changing of omega-6/omega-3 polyunsaturated fatty
acids (PUFA) in the food supply of Western societies oc-
curred over the last 150 years is thought to promote the
pathogenesis of many inflammatory-related diseases, in-
cluding depressive disorders. Several epidemiological stud-
ies reported a significant inverse correlation between intake
of oily fish and depression or bipolar disorders. Studies
conducted specifically on the association between omega-3
intake and depression reported contrasting results, suggest-
ing that the preventive role of omega-3 PUFA may depend
also on other factors, such as overall diet quality and the
social environment. Accordingly, tertiary prevention with
omega-3 PUFA supplement in depressed patients has
reached greater effectiveness during the last recent years,
although definitive statements on their use in depression
therapy cannot be yet freely asserted. Among the biological
properties of omega-3 PUFA, their anti-inflammatory ef-
fects and their important role on the structural changing of
the brain should be taken into account to better understand
the possible pathway through which they can be effective
both in preventing or treating depression. However, the
problem of how to correct the inadequate supply of omega
-3 PUFA in the Westernized countries' diet is a priority in
order to set food and health policies and also dietary rec-
ommendations for individuals and population groups.

Global methylmercury exposure from
seafood consumption and risk of develop-
mental neurotoxicity: a systematic review

OBJECTIVE: To examine biomarkers of methylmercury
(MeHg) intake in women and infants from seafood-
consuming populations globally and characterize the com-
parative risk of fetal developmental neurotoxicity. METH-
ODS: A search was conducted of the published literature
reporting total mercury (Hg) in hair and blood in women
and infants. These biomarkers are validated proxy
measures of MeHg, a neurotoxin found primarily in sea-
food. Average and high-end biomarkers were extracted,
stratified by seafood consumption context, and pooled by
category. Medians for average and high-end pooled distri-
butions were compared with the reference level established
by a joint expert committee of the Food and Agriculture
Organization (FAO) and the World Health Organization
(WHO). FINDINGS: Selection criteria were met by 164
studies of women and infants from 43 countries. Pooled
average biomarkers suggest an intake of MeHg several
times over the FAO/WHO reference in fish-consuming
riparians living near small-scale gold mining and well over
the reference in consumers of marine mammals in Arctic
regions. In coastal regions of south-eastern Asia, the west-
em Pacific and the Mediterranean, average biomarkers ap-
proach the reference. Although the two former groups
have a higher risk of neurotoxicity than the latter, coastal
regions are home to the largest number at risk. High-end
biomarkers across all categories indicate MeHg intake is in
excess of the reference value. CONCLUSION: There is a
need for policies to reduce Hg exposure among women
and infants and for surveillance in high-risk populations,
the majority of which live in low-and middle-income coun-
tries.
