OF
TO 2000
The Integrated Atmospheric Deposition Network was initiated in 1990 to measure atmos-
pheric concentrations of persistent toxic pollutants in the Great Lakes basin. These meas-
urements have been conducted at 5 master stations, one on each of the Great Lakes, as well
as 10 satellite stations. The measured concentrations combined with physical parameters
have formed the basis of loadings estimates produced by IADN every two years. This
report presents the results of the loadings estimates for the years 1999-2000.
In the IADN calculations, processes of wet deposition via precipitation, dry deposition of
particles and gas absorption at the water interface are taken into account. Volatilization
from the Lakes is also important, and this is estimated using water concentrations from
other monitoring or research projects for some compounds. The calculations in this report
build on previous reports although several modifications have been made. The estimates
are now calculated monthly instead of seasonally. The rates of precipitation and wind
speeds, involved in the calculations, are lakewide values instead of "at station" measure-
ments. Several Henry's law constants have been updated. Given these upgrades, loading
estimates from previous years were re-calculated using the new model. The use of
lakewide precipitation rates and wind speeds has changed the magnitude of the loading
estimates on an annual basis by 25% for wet deposition and by a factor of two or less for
gas absorption.
For all Lakes, loading estimates of banned organochlorine (OC) pesticides, such as
oc-HCH, continue to decline. For several OC pesticides, including chlordanes and p'p'-
DDT, loading estimates are relatively small, with fluxes often less than 2 ng/mVday.
Dieldrin is volatilizing out of the Lakes, while HCB is depositing in Lake Superior but
volatilizing out of Lakes Michigan and Erie. Current-use pesticides such as y-HCH and
oc-endosulfan are still depositing to the Lakes from the atmosphere and as expected show
no trend. The monthly calculations revealed seasonality for several OC pesticides. a-HCH
loading estimates have a strong seasonality with maxima in summer for both absorption
and volatilization. These maxima are likely due to an increase in atmospheric concentra-
tion of a-HCH in the summertime combined with a favorable temperature-dependent
Henry's law constant. y-HCH (lindane) fluxes also presented a strong seasonal behaviour
of the absorption process with maxima in spring. These correspond to planting of canola
seeds in the Canadian prairies and subsequent transport of lindane to the Great Lakes as
demonstrated by other researchers.
The PCBs considered in this report (18, 44, 52, 101 and suite PCB) all continue their
trends of volatilizing out of the lakes, however tending towards equilibrium. Given that the
water concentrations used in this report are similar to the ones in the 97-98 report, it is not
surprising that the magnitude of the volatilization has remained the same in recent years
with fluxes for suite PCB less than 50 ng/mVday. PCB loading estimates also show
some seasonality.
Loadings of PAHs have remained constant over time, which is consistent with the com-
bustion sources of these chemicals. The semi-volatile character of PAHs results in heavier
PAHs entering the Lakes through dry and wet deposition while for lighter PAHs, absorp-
tion is most prominent. Most PAHs total loading estimates are similar for all lakes with
in
-------
Lake Erie being slightly larger. One exception is phenanthrene for Lake Erie where total
fluxes are 2 to 4 times larger than the other Lakes. Seasonal patterns of dry deposition
reflect the seasonality of sources and the temperature dependent partitioning of PAHs with
larger estimates in winter when particulate concentrations are expected to be larger.
Metals total loading estimates are of similar magnitudes for both Lake Ontario and Huron
(the only Lakes for which metals data are available). Wet deposition is always more impor-
tant than dry deposition and there is a lack of trend over time. This is consistent with
Canadian emission sources that have remained constant over the last few years. Slight
increases in loading estimates are observed in the winter months.
The influence of urban areas on the lakewide loading estimates was evaluated using the
satellite site of Chicago, the only urban site in operation in 99-00. Total downward fluxes
were compared between the Master station at Sleeping Bear Dunes and Chicago. For pes-
ticides, similar fluxes were seen while PCBs and PAHs fluxes were much larger in
Chicago. The urban effect of Chicago was investigated and as in previous IADN reports,
it was found that there is a substantial effect for PCBs and PAHs. This points to the criti-
cal importance of including urban data in the loading estimates.

In 1987, a revision of the Great Lakes Water Quality Agreement of 1978 included a sepa-
rate Annex (Annex 15) which called for the creation of the Integrated Atmospheric
Deposition Network (IADN) to carry out surveillance and monitoring of the toxic contam-
inants. In accordance with Annex 15, IADN has produced biennial loading estimates on
data from 1992 through 1998 (Hoff, 1996; Hillery et al., 1998; Galameau et al., 2000;
Buehler et al, 2001). This report details the 1999 and 2000 atmospheric loadings to the
Great Lakes. It also defines a new reporting format for the IADN loading estimates. This
new format consists of a standard "front end" that includes the sampling and analytical sta-
tus of IADN and a section detailing recent improvements to the loadings calculations. A
short summary of results is presented followed by tables and figures of loading estimates.

2.1.
IADN collects gas, particle, and precipitation phase samples at each of its master stations,
one on each of the Great Lakes (see Figure 1). Sampling details can be found elsewhere
(Environment Canada, 1994; Basu, 1996). Master stations on Lakes Erie(Sturgeon Point,
STP), Michigan (Sleeping Bear Dunes, SBD) and Superior (Eagle Harbour, EGH) are
operated by the United States (Indiana University, IU, via a cooperative agreement with US
EPA) while Canada (Meteorological Service of Canada, MSC) operates the Master stations
on Lakes Huron (Burnt Island, BNT) and Ontario (Point Petre, PPT). On the US side, two
satellite urban stations are in operation in Chicago and Cleveland. Both air and precipita-
tion samples are collected at these sites. On the Canadian side, air samples are collected at
MSC's satellite site of Egbert (EGB) while only precipitation samples are collected at the
other six satellite stations. The Ecosystem Health Division (EHD) of Environment Canada-
Ontario Region is responsible for these precipitation satellite stations.

2.3.
2.3.1. Precipitation
The details of all sampling protocols are given in the Sampling Procedures Manuals for
each agency. These details will be reviewed briefly here. All stations (including all
Satellite facilities except Egbert) have samplers to measure wet deposition of gaseous
organics. The precipitation sampler used for the organics measurements is uniform across
the network, a MIC-B collector with a stainless steel funnel.
Indiana University uses XAD-2 resin column cartridges for accumulating the organics.
EHD uses a dichloromethane solvent extraction system in which the rainwater is stabilized
with 250 mL of dichloromethane then liquid/liquid extracted using fresh dichloromethane.
Indiana University samples precipitation on a 28-day cumulative basis. EHD takes 14-day
cumulative samples; however, as of 2000, the 14-day samples are composited to 28-day
samples prior to analysis. The start and finish dates for the 28-day period are aligned
between the two agencies. For trace metals, EHD uses a MIC-B precipitation sampler. The
precipitation samples are collected in pre-cleaned polyethylene buckets. Indiana
University does not measure trace metals.
2.3.2. Air
Organics air sampling uses modified high volume samplers with filter and absorbent com-
binations. Indiana University uses a HiVol of identical design, which has an XAD
absorbent cartridge. This allows for a >800 m3 sample volume. MSC uses polyurethane
foam as the absorbent for organics. In this case, sample volumes are kept below 400 m3 to
avoid breakthrough of lighter organics during warm summer months. The metals are col-
lected on a glass fiber filter at the sites of Point Petre and Burnt Island using a dedicated
hi-vol sampler for a total air volume of 1625m3. All agencies have now adopted a sampling
frequency of a 24-hour sample every 12 days. Early results showed that little organochlo-
rine mass was found on the filter. For example, at the Point Petre station in 1992, the par-
ticulate/gaseous mass ratio was 2.3% for total PCBs and < 1% for the HCHs, p,p '-DDE,
-------
and HCB. Due to the low analyte masses on the filters, agency protocols have changed
over the course of IADN. The general absence of most organochlorine pesticides and
PCBs on the filters led Environment Canada to terminate the measurements of these com-
pounds on filters in 1993. Indiana University stopped PCB analysis on filters in 1996;
however, ID continues to analyze the pesticides on the filters because of their higher con-
centrations in the urban samples.
2.4. Chemical Analyses
Laboratory analysis protocols generally call for solvent extraction of the organic sampling
media with addition of surrogate recovery standards. Extracts are then concentrated fol-
lowed by column chromatographic cleanup, fractionation, nitrogen blow-down to small
volume and injection into GC-ECD, HPLC or GC-MS instruments (Figure 2, 3, 4). Details
of these analyses can be found in the agency project plans (e.g. Basu and Hillary, 1995).
Metals analyses for Canadian samples are conducted using inductively coupled plasma
emission for particulate and precipitation samples.

IADN follows a strong quality assurance program. The Quality Assurance Program Plan
(QAPP) was documented jointly by Environment Canada, the United States
Environmental Protection Agency, and the Ontario Ministry of the Environment and
Energy (February 1994). All air and precipitation chemical data and all meteorological
data measured by IADN go through a quality control process via the Research Data
Management and Quality Control System™ (Sukloff et al., 1995).
Based on the results of our quality assurance studies to date, differences in loading esti-
mates among sites/lakes should be viewed in consideration of the identified measurement
differences among agencies involved in IADN. Some of these differences include (Fowlie,
2001): for PAHs, IU [Indiana University] reports data about 30% higher than MSC
[Meteorological Services of Canada] for gas-phase samples but there was no such bias for
particles or precipitation. For PCBs in the gas phase, RJ reported data about 30% higher
than MSC. For pesticides, IU reports data about 30% higher than MSC in the gas phase
but comparable to NLET for precipitation. It is important to note that these results can only
be applied to one point in time early in 2001 and should not be applied without caution to
the 10 years of the IADN program. These issues continue to be addressed to ensure that
data are compatible.

3.1.
Detailed descriptions of the loadings calculations can be found elsewhere (Hoff, 1994;
Hoff et al., 1996; Hillery et al., 1998). A brief summary will be presented here. Net atmos-
pheric flows (L, in kg/yr) are based on three processes: wet deposition, dry deposition, and
net gas exchange. They are represented by the equation:
L = CrRpA i C^VjA * [kol(\ WCj(RT/H)A kol(\ ^JC^AJ (1)
Wet deposition is the product of the volume-weighted mean precipitation concentration, Cp
(kg/m3), the rate of precipitation, Rp (m/yr), and the area of the lake, A (m2). Dry deposition
is the product of the total atmospheric concentration of the pollutant, Ca (kg/m3), the fraction
of the compound in the particle phase, 0a, the deposition velocity of the particles, vd (m/yr),
which is taken as 0.2 cm/s for all chemicals, and the area of the lake, A (m2). The product of
Ca and (j)a is operationally defined as the concentration obtained on the filter samples.
Atmospheric concentrations are obtained from the measurements at master stations. It should
be noted that the use of 0.2 cm/s does not accurately reflect the deposition velocity of all par-
ticles and most likely results in an underestimation of dry deposition.
Net gas exchange is divided into two components: absorption and volatilization. The vari-
able, k0i (m/yr), is the overall air-water mass transfer coefficient, R (atm m3 K4 mol"1) is the
ideal gas constant, T(K) is the temperature at the air-water interface, H (mol atnr1 nr3) is the
Henry's Law constant, and Cw (kg/m3) is the concentration of the compound in water. For
absorption, (1 - (f)a)Ca is the air concentration of the compound in the gas phase as obtained
operationally on the PUF or XAD media. Absorption is the transfer of the compound in
the gas phase from air to water. In the volatilization term, (j)w is the fraction of the com-
pound on the particle phase in the water, thus making (1 - 0W)CW the dissolved phase con-
centration of the compound of interest. Volatilization is then the transfer of the compound
from water to air. Net gas exchange is the sum of the absorption and volatilization esti-
mates. The convention in this report is that positive net gas exchange indicates absorption,
while negative net gas exchange indicates volatilization.
-------
The loadings estimates are presented in this report as both flows and fluxes. Fluxes
(ng/mVday) are simply the flows (kg/month) converted to ng/day and divided by the appro-
priate lake area. These areas are 82,100 km2 for Lake Superior, 57,800 km2 for Lake Michigan,
59,600 km2 for Lake Huron, 25,700 km2 for Lake Erie, and 18,960 km2 for Lake Ontario.
Fluxes allow for comparisons between the lakes by removing the variation due to differing
lake areas. In past IADN reports, flows and fluxes were calculated seasonally and then
summed to give annual loads and averaged to give annual fluxes. In this report, loadings esti-
mates of dry and wet deposition and absorption are calculated monthly. Volatilization
estimates are calculated annually and presented in a separate section since IADN does not
measure water concentrations and must rely on other researchers' measurements.
In this report, errors are presented for each term as a coefficient of variation (COV). These
COVs were calculated in accordance with the error propagation analysis by Hoff (1994).
However, because monthly loadings estimates are now calculated, the standard deviation
over mean as a measure of uncertainties for ambient air concentrations was not used
because only 2-3 values were available. Instead, limit of detection over mean was adopt-
ed. This has resulted in slightly smaller overall COVs since temporal variability was one
of the major source of error in previous reports.
3.2.
The 1999-2000 Report includes several improvements to the calculation of the modeled
estimates. The first significant improvement is the conversion to the Statistical Analysis
System (SAS) format from an Excel-based program. The use of SAS allows direct transfer
of the IADN data from the quality control process via the Research Data Management and
Quality Control System™ (Sukloff et al., 1995). Further calculations will now be automat-
ed and thus results will be available shortly after data delivery. For the purpose of calcula-
tions, non-detect data values were set to zero. Other improvements have been done to various
parameters in the model. These improvements affect the wet deposition and gas exchange
terms of equation 1 and are discussed below. Considering the many changes to the calcula-
tions, flows and fluxes for all years were recalculated using the new information.
3.2.1 Rate of Precipitation, Rp
In past reports, the rate of precipitation Rp (m/yr) has been derived from data collected at
each Master Station. This was then applied to the rest of the Lake although it had been rec-
ognized that this might not properly represent the rate of precipitation over the entire Lake.
In this report, rates of precipitation have been obtained from the Great Lakes
Environmental Research Laboratory (http://www.glerl.noaa.gov/) and averaged monthly.
The NOAA estimates use multiple land-based measurements to interpolate area-weighted
overtake precipitation amounts using the Thiessen method (Huggins, 1996). The ratios of
lakewide precipitation estimates versus the precipitation rate at station are presented in
Figure 5 for all Lakes for all years. For all Lakes, averages of these ratios are close to unity
with RSD of the order of 40 to 70% due to monthly variability. Therefore although for the
entire period, the updated precipitation rates may not drastically impact the wet deposition
estimates, they will be affected for certain months/Lakes.

3.2.2 Henry's Law Constant, H
Modification of the Henry's law constants (H) strongly affects mass transfer coefficients
and absorption (Equation 1). For this report updated Hs were adopted for PCBs based on
the work of Li et al (2003). A list of all the Hs used is given in Table 3. Li et al. do not
report temperature-dependent Hs for congeners 18 and 44. Congener 28 and 52 were used
as surrogates of tri and tetra chlorinated PCB, respectively. Thus their temperature-
dependent Hs were applied to PCB 18 and PCB44. For the suite PCB, each homologue
group was weighted according to its occurrence in ambient air samples (Neilson, 2000)
and the same weight was used to obtain a "suite" H. The suite H equation is similar to the
tetra homologue group that is the most prominent group in the atmosphere around the
Great Lakes. It is important to note that the choice of Henry's law constants is critical to
the resulting loadings estimates. Therefore further work will be ongoing to assess the
effects of other researchers published H values on loadings calculations.

U10
In previous reports, the wind speed at 10 meters (U]0) has been obtained from measure-
ments at station and then applied to the entire lake area. A better representation of lakewide
wind speeds has now been obtained and incorporated into the model. Monthly wind speed
values derived by NOAA (NOAA, 2000) from over-water buoy data were used. The
impact of these updated wind speeds is quite significant because it affects the air-water
mass transfer coefficient. Kol is calculated from the water-side and air-side mass transfer
coefficients following
RT
(2)
kol kw Hka
The equation for the water-side mass transfer coefficient is (Galarneau et al, 2000):
,* = 0.45wio
1.64
sO.6
(-0.5or-0.66)
(3)
The exponent will change depending on wind speed: if LJ10<3.6 then -0.66 is used for the
exponent and if U10±3.6 then -0.5.
While the air-side mass transfer coefficient is:
n0.61
(l/M + 1/29)05
(4)
Where Fm-x is the molar volume, Mx is the molecular weight, ZFd is the atomic diffusion
volume, all three quantities are specific to each chemical of interest. Therefore it is read-
ily seen that a modification of the wind speed results in a substantial change of kw, ka and
thus kol.
The ratios of lakewide wind speed estimates versus wind speeds measured at station are
plotted in Figure 6 for all Lakes for all years. As can be observed there are substantial dif-
ferences in wind speeds measured at the stations versus integrated overlake values mostly
resulting in larger wind speeds. This will in turn impact the mass transfer coefficients
where a doubling of wind speed will result in an increase of kol by a factor of 2 to 4.
Undoubtedly this will affect the gas exchange term of equation 1.

Figure 6. Ratios of lakewide and at station wind speeds for all measurements.
It is important to note that this effect is not as significant for Lake Ontario where the ratio
of new to old wind speed is lowest. This is likely due to the fact that the IADN site on that
lake is located on a peninsula extending into the lake and thus the meteorological meas-
urements at station reflect open lake conditions.
As discussed in section 3.1, lake water concentrations, although crucial to the loadings cal-
culations, are not measured on a routine basis as part of IADN. No new data were avail-
able for 1999-2000, therefore water concentration data for 1997 and 1998 from available
sources were used (Buehler et al., 2001). If more than one source was available for a given
lake for one year, the water concentration data were pooled by the method of weighting by
inverse variance (Taylor, 1990).
4. Results
A comparison of annual wet deposition flows (kg/yr) between results contained in this
report and results for 1997-98 calculated using the old method (Buehler et al., Appendix D)
indicates a difference of 25% or less. This difference can be explained by the adoption of
overtake precipitation for the calculations herein. The introduction of overtake wind
speeds has also increased the absolute magnitudes of absorption and volatilization by one
and a half to two times. Furthermore, the water-side mass transfer coefficient is also
dependent on wind speed (the exponent term, Equation 3) as the wind speed goes from less
than 3.6 m/s at station to more than 3.6 m/s overtake. The water concentrations were
obtained as annual averages. Earlier in lADN's operation, particulate concentrations were
found to be insignificant for pesticides and PCBs, so dry deposition is not determined for
those chemicals.

4.1 Organochlorine pesticides:
4.1.1 oc-HCH
Wet deposition fluxes of oc-HCH appear to be decreasing particularly for Ontario and
Huron. For all lakes, the amount of precipitation has not significantly varied since 1992
therefore the decreasing trend is due to a decline of oc-HCH in precipitation. This has been
shown before (Chan et al. 2003) and attributed to international changes in usage patterns.
Lakes Huron and Ontario have larger wet deposition fluxes than the other Lakes.
The magnitude of both absorption and volatilization has decreased overtime, and air-water
exchange for oc-HCH is approaching equilibrium whereby absorption from the atmosphere
equals volatilization from the Lake. The volatilization trends for Lake Michigan and
Huron are driven by the difference in water concentration data pre- and post-1994.
A strong seasonality is observed for both absorption and volatilization of oc-HCH with
maxima in the summer months (Figure 7). The strong seasonality observed is likely a
result of the temperature dependence of source strengths of banned OC pesticides i.e.
increased summertime volatilization from soils where they were historically applied.
Figure 7. (X-HCH monthly absorption and volatilization fluxes for Lake Superior.

-------
Figure 8. y-HCH monthly absorption and volatilization fluxes for Lake Michigan.
4.1.2y-HCH (Lindane)
Wet deposition fluxes of y-HCH have remained similar throughout the nineties. This is not
surprising because lindane is a current-use pesticide in Canada that has been shown to
impact the Great Lakes region (Ma et al. 2003). For all Lakes, lindane is still showing net
deposition through absorption from the atmosphere. All Lakes present a strong seasonality
(Figure 8) with maxima in absorption fluxes in April-May-June. Lindane has been used
extensively in the Canadian prairies as a seed treatment for canola and re-emission from
soil usually occurs in April-May (Waite et al. 2001). This re-emission from the Canadian
prairies can then be transported to the Great Lakes basin. This is clearly seen from the tem-
poral variation of the absorption results. Some volatilization of lindane from the Lakes
occurs in summer but this is usually relatively small compared to the spring atmospheric
deposition.
For oc-HCH, the use of overtake wind speeds has had the result of increasing both absorp-
tion and volatilization significantly compared to Buehler et al. This is partly due to the fact
that the atmospheric concentration maxima are in summer when the wind speed differ-
ences are more pronounced. However, in the case of lindane, the absorption component
will not be as influenced since lindane has a springtime maxima when wind speeds at sta-
tion and overtake are relatively comparable. Thus the magnitude of lindane absorption
fluxes to the Lakes is comparable to results obtained by Buehler et al. However the
volatilization term will be affected since most lindane volatilization occurs in summer.

4.1.3 Dieldrin
Dieldrin has been used directly as a pesticide on crops but is also a degradation product of
aldrin; both were deregistered in 1987. This banned pesticide has been volatilizing from
the lakes since 1992. As with other compounds, the inclusion of the overlake wind speed
had a doubling effect on the volatilization and also results in a seasonal pattern with larg-
er volatilization in summer (when wind speeds are largest).
4.1.4HCB
HCB absorption data are only reported for Lake Superior, Michigan and Erie due to break-
through during air sampling at the Canadian sites. At all sites HCB is tending towards
equilibrium with absorption and volatilization having similar magnitudes. Fluxes are
between 15 and -15 ng/mVday for all three lakes indicating the ubiquity of HCB. There is
a strong seasonality of both absorption and volatilization fluxes for all Lakes with maxi-
ma in winter. While most OC pesticides usually peak in summer, HCB has a relatively
large Henry's law constant (H) yielding mass transfer coefficients with winter maxima.
4.1.5 Chlordanes
Cis-chlordane, trans-chlordane, trans-nonachlor
Technical chlordane was used extensively for termite control and phased out in the US in
1988. Volatilization from soils is the predominant source of chlordanes to the Great Lakes
(Hafner and Kites, 2003). In this loadings report, only wet deposition and absorption flux-
es are included. The fluxes of chlordanes are small, often less than 1-2 ng/mVday. Lake
Erie has the largest absorption fluxes for all three compounds.
4.1.6 DDT and Metabolites
p,p'-DDT; p,p'-DDD;
DDT has been banned in Canada and the United States since the early 1970s, while
Mexico banned its use in 2000. For these compounds, absorption fluxes dominate and are
larger for Lake Erie. Fluctuations throughout the nineties are observed; for example, p,p'-
DDT showed a slight increase in absorption during the summers of 1999 for Lake
Michigan. The increase seen in wet deposition for Lake Huron and Ontario in 1997 is due
to a single monthly sample of large concentration.
4.1.7 oc-endosulfan
oc-Endosuifan is a current-use pesticide employed on fruit and vegetable crops with heavy
uses in New York, Michigan and some use in Ontario. Absorption fluxes dominate depo-
sition to the Lakes with larger fluxes for Lakes Michigan, Erie and Ontario. Wet deposi-
tion is also relatively significant for Lake Ontario. Similar to lindane, the other current-use
pesticide measured by IADN, oc-endosuifan deposition presents a strong seasonal pattern
with maxima in summer consistent with application patterns.

Figure 9. Suite PCBs absorption and volatilization for Lake Erie.
4.2 Polychlorinated Biphenyls, PCBs
Fluxes for the individual PCB congeners (18, 44, 52, and 101) generally reflect patterns of
the suite. Wet deposition constitutes 7-15% of downward deposition on average (note that
wet deposition fluxes are multiplied by 10 in Figure C16). There is no discernable trend
over time for wet deposition and fluxes are similar among lakes for which recent data are
available (Superior, Michigan, and Erie). It is also noteworthy to mention that the PCB
concentrations in precipitation are getting very small relative to blank concentrations, par-
ticularly at the sites of Eagle Harbour and Sleeping Bear Dunes. Gas exchange is the dom-
inant process for PCBs. Overall deposition of PCBs continues to decrease, with air-water
exchange dominated by volatilization out of the Lakes, but tending towards equilibrium,
particularly for Superior and Michigan. Some increases in absorption are seen in the late
1990s for Lakes Superior, Michigan, and Erie. Absorption decreases again by 2000.
Monthly absorption and volatilization fluxes are plotted for Lake Erie. PCB fluxes tend to
be largest for Lake Erie. The Lake Erie master station, Sturgeon Point, may be influenced
by source areas of PCBs in New York State and in the highly populated areas on the east-
ern seabord of the U.S. (Hafner and Kites, 2003).

Figure 10. Pyrene Monthly Dry Deposition for Lake Ontario.
4.3 Poly cyclic Aromatic Hydrocarbons, PAHs
Phenanthrene, Pyrene, B(a)P, Indeno, B(b+k)F
For the lighter PAHs (e.g. phenanthrene), absorption fluxes dominate deposition to the
Lakes whereas for the heavier PAHs (e.g. B(a)P), wet and dry deposition are the main
pathways of entry into the lakes. Fluxes are largest for Lake Erie, particularly absorption,
again emphasizing the impact of urban emissions on the Sturgeon Point site.
For all lakes no particular temporal trend is observed consistent with current emissions
of these combustion by-products. Across the basin, dry deposition of PAHs is larger in
winter (Jan.-Apr.) reflecting the tendency of these semi-volatile compounds to partition to
aerosols in colder temperatures (Figure 10). Furthermore, domestic heating is expected to
contribute to winter PAHs maxima. For phenanthrene and pyrene, absorption fluxes might
be expected to be larger in summer when temperatures are warmer and the more volatile
PAH will partition to the vapour phase. This is only observed for Lake Superior. For the
other lakes, the increase in domestic heating sources in winter seems to obscure this
pattern and thus seasonality is not as marked.

4.4
Lead, Cadmium, Arsenic, Selenium
For all metals, wet deposition fluxes are larger than dry deposition. For the present calcu-
lations, the deposition velocity was 0.2 cm/s for all organochlorines, PAHs and metals.
More information is needed to accurately describe the dry deposition process, in particu-
lar the use of a single value deposition velocity. For trace metals, it is possible that dry dep-
osition fluxes are underestimated. No trends in dry or wet deposition were observed for
both Lakes. This is not surprising since Canadian atmospheric emissions have not signifi-
cantly declined since 1992.
4.6
Many air monitoring studies in urban areas have shown higher levels of toxic pollutants
than exist at more rural sites (Simcik et al., 1997; Miller et al., 2001; Hatner et al., 2004).
Lakes Michigan, Erie, and Ontario are likely significantly affected by deposition from
urban areas such as Chicago/Milwaukee, Cleveland, and Toronto/Hamilton. Therefore,
loadings calculated using only master station data most likely underestimate deposition to
the Great Lakes. In the past, the only urban IADN station was located on the Illinois
Institute of Technology campus in Chicago. In late December of 2002, a new monitoring
site was established in Cleveland, Ohio. Data from this site will assist IADN in estimating
urban inputs to Lake Erie. The previous two IADN loadings reports (for data from 1995-
96 and 1997-98) calculated fluxes and loadings using Chicago data to estimate the influ-
ence of that urban area on atmospheric deposition to Lake Michigan. This exercise has
been repeated for this report.
Fluxes calculated using Sleeping Bear Dunes data and Chicago data are compared.
Chicago data are then applied to an area of the lake representing the "urban plume" to
examine the increase in loadings to the Lake. Flux and loadings estimates were made on
an annual basis, and average lakewide surface water temperature and precipitation rates,
as well as overwater wind speeds, were used. As for loadings results for Sleeping Bear
Dunes, the water data used were unpublished EPA data from 1997 (the most recent avail-
able). Volatilization estimates are not available for many chemicals due to the lack of
available data. In addition, dry deposition estimates could not be made for some com-
pounds due to lack of particulate concentration measurements (most notably for PCBs).
Table 4 shows a comparison of fluxes occurring at Sleeping Bear Dunes (the background
site) and Chicago. Examination of total net inputs (not including volatilization) indicates
that total downward fluxes in 1999 were greater at Chicago for all chemicals except
oc-HCH and a-endosulfan. Fluxes were generally higher in Chicago but of the same mag-
nitude for the DDTs and HCB, while the chlordane components were about ten times high-
er at Chicago. Actually, downward fluxes of the HCHs, a-endosulfan, and HCB are very
similar between the two sites. The comparability of the pesticide fluxes between the two
sites may be due to the fact that many of the IADN pesticides were used in agriculture in
more rural areas, like those near Sleeping Bear Dunes. Chlordane was used for termite
control, explaining the greater presence in the urban area. The comparability of HCB fluxes
may simply reflect the ubiquity of HCB as a pollutant, in part due to its ability to be trans-
ported easily over long distances from sources to more remote areas.
19
-------
The situation is different for PCBs and PAHs. Total downward fluxes of PCBs were about
ten times higher in Chicago. Downward fluxes of PAHs were generally about 20-75 times
higher at the urban site. Examination of volatilization was limited due to the availability
of water data, but for PCBs (with the exception of PCB 52), addition of Chicago data usu-
ally resulted in a switch in direction for gas exchange from net volatilization (but general-
ly near equilibrium) at Sleeping Bear Dunes to net deposition at Chicago. Net gas
exchange of PCB 52 was positive at both SBD and Chicago. Chicago fluxes in all deposi-
tion categories tended to decrease from 1999 to 2000 reflecting patterns at the master sta-
tions.
Elevated PCB fluxes at Chicago may be due to continued inputs of PCBs from landfills,
sewage sludge drying beds, and historically contaminated sites in the area (Hsu et al.
2003). High PAH fluxes are most likely due to a high concentration of industry in the
Chicago-Gary, IN area as well as contributions from motor vehicles.
Patterns in dominant deposition processes reflect those at the master stations: the pesti-
cides, PCBs, and lighter PAHs (phenanthrene and pyrene) have highest fluxes for absorp-
tion, whereas the heavier PAHs have higher fluxes for wet and dry deposition than for
absorption. Wet deposition fluxes were lowest for pesticides and HCB and higher for
PCBs and PAHs at Sleeping Bear Dunes, and the same is the case at Chicago. Wet depo-
sition fluxes are higher in the city, particularly for PAHs. When compared to past fluxes
(1996-1998), newly calculated Chicago wet deposition fluxes were either comparable or
lower. For dry deposition, pesticide fluxes are much lower than PAH fluxes at both SBD
and Chicago. Similar to wet deposition, dry deposition fluxes of PAHs are much higher at
the Chicago site, in the hundreds of ng/mVd compared to fluxes in the single digits at SBD.
Dry deposition fluxes at Chicago have been for the most part consistent over time.
Absorption fluxes for dieldrin, chlordane component compounds, and DDT and its degra-
dation productions were quite a bit higher (about five to ten times) at Chicago versus SBD.
The urban effect on absorption fluxes was even higher for PCBs (8-22X) and the lighter
PAHs (40-100X).
Reflecting a pattern found at the master stations, the magnitude of the absorption and
volatilization fluxes has increased by about two for many compounds (versus the results
for 1996-98, which used old methods of calculation). This is most likely due to a method
change, namely the use of overtake wind speeds, which are greater than at-station wind
speeds, rather than a change in the state of the environment. The method change also
results in higher net loads (wet + dry + absorption + volatilization), which can be calculat-
ed for substances with available water data.
Loadings (in kilograms per year) to Lake Michigan as a whole were also calculated taking
Chicago's influence into account. As in the past, the "urban plume" surface area where
Chicago data was applied was 100 km of shoreline and 10 km offshore for wet and dry
deposition (1,000 km2, or 1.7% of the total lake area) and 100 km by 20 km offshore for
gas exchange (2,000 km2, or 3.5% of the total lake area) (See Galarneau et al. 2000). It is
assumed that Chicago-originated pollutants in the vapor phase have a more extensive spa-
tial influence out over the lake, since particles and affected precipitation deposit closer to
the city. In addition, the percentages of the time that winds were blowing from Chicago
out onto the Lake (winds from entire southwest quadrant) were calculated using 1999 and
2000 station-specific hourly meteorological data from IIT. This was used to determine the
fraction of the time that the Chicago concentrations/fluxes should be applied to the affect-
ed area of the lake. These percentages were 32.8% and 35.2% for 1999 and 2000, respec-

tively, and are similar to such percentages from past calculations showing that contaminat-
ed urban air blows out onto the lake roughly a third of the time.
Table 5 shows loadings for Sleeping Bear Dunes and Chicago, as well as a percentage
urban effect (the ratio of the extra loading provided by Chicago to the lakewide loading
calculated using only Sleeping Bear Dunes data). Since loadings are simply fluxes applied
to the Lake as a whole, general patterns for loadings reflect those found in the fluxes. Total
downward loadings ("net input" which do not include the effects of volatilization) show
that Chicago has a minimal effect for the HCHs, a-endosulfan, p,p'-DDD, and HCB.
Urban effects of about 5-10% are found for dieldrin, the chlordane components, and p,p'-
DDT and its degradation product p,p'-DDE. Since gas exchange is the dominant deposi-
tion process for the pesticides and HCB, increases in absorption drive urban effects, and
wet deposition and dry deposition generally have a lower urban effect than for gas absorp-
tion for these substances.
Urban effects for total downward loads for PCB congeners range from 7% to 20%, with
about a 10-13% added effect for Suite PCBs. When volatilization is included, in most
cases there is a negative urban effect, indicating a switch from net volatilization at the rural
site to net deposition at Chicago. The exception is PCB 52, which has positive net deposi-
tion at both sites, and Suite PCB in 1999, which for the first time since early in the IADN
program shows total deposition (including all pathways) to be positive at Sleeping Bear
Dunes, though the Suite PCB contribution from Chicago for that year is still three times
higher than the lakewide loading calculated using data from SBD. However, Suite PCB
total deposition for SBD becomes negative again in 2000.
Urban effects for PAH loadings are sizable in all deposition categories. Since wet and dry
deposition are more significant for the heavier PAHs than for PCBs and the pesticides,
urban effects for these processes are higher than was the case for pesticides and PCBs, usu-
ally between 10-40%. Urban effects for absorption are high, increasing deposition partic-
ularly for phenanthrene and pyrene, the ligher PAHs. Total downward loadings are
increased by 12 to 72% for PAHs.
Fluxes and loadings for Chicago for 1999 and 2000 reiterate the conclusion from past
IADN loadings reports that cities can have a significant effect on atmospheric deposition
to the Lakes, particularly for PCBs and PAHs. The effect of urban pollution on deposition
to Lake Michigan is likely greater than that described here for Chicago, since cities like
Milwaukee and Green Bay are not included. Data from the new Cleveland station will shed
further light on urban effects on the Great Lakes.

The IADN data are not blank corrected. Therefore it is important to present loadings esti-
mates obtained from blank values to understand the proportion of calculated deposition
due to blanks. For IADN, MSC air field blanks are obtained by sending a sampling medi-
um to the field and retrieving it with only a short period of exposure to ambient air (with-
out pumping air through). IU blank cartridges are installed in the sampler, kept there for
one week, and then returned to the laboratory. The results are representative of analytical
blanks and potential interferences from the sampling media. Precipitation blanks for the
US samples are XAD cartridges sent out to the field, installed in the sampler, kept there
for 28 days, and then shipped back to the laboratory for extraction. Water concentration
blanks are prepared by placing a clean filter in the sampling device, wetting with organic
free water then shipping for chemical analysis.
Results are presented in Table 6 for Lake Superior and Ontario to represent the different
laboratories involved in the program. For pesticides such as HCHs, the blank loadings are
small compared to the sample values from less than 1% to about 5%. Dieldrin blanks are
a little more prominent with the blank loadings representing 5-10%, 3% and 8% of the wet
deposition, absorption and volatilization respectively. HCB blank loadings are larger par-
ticularly for wet deposition (13-17%) and volatilization (26%). Cis- and trans-chlordane
have blank loadings of the order of 10-30% for wet deposition with smaller blank loadings
for absorption. DDT and metabolites can have large blank loadings, particularly for wet
deposition, due to the small concentrations now measured for these species. PCBs blanks
contribute between 10 and 35% of loadings for all terms. For the heavier PAHs mostly
found on particles, blank loadings for absorption are very large compared to what is found
in air while lighter PAHs mostly found in the gas phase have large dry deposition blanks
relative to dry loadings.
