ENVIRONMENTAL
            CRISIS
     IN THE  GULF
          THE U.S. RESPONSE
U.S. efforts in the Gulf were requested by and conducted in cooperation with the
allied Gulf states, under the aegis of various national, regional, and international
organizations, including: the United Nations Environmental Programme; the
World Health Organization; the World Meteorological Organization; the Inter-
national Maritime Organization; the International Oceanographic Commission;
King Fahd University of Petroleum and Minerals/Research Institute; the Saudi
Arabia Meteorological and Environmental Protection Administration; and the
Kuwait Environmental Protection Department, Other nations and organizations
also provided technical, material, and financial assistance.

                                    Introduction
   On November 5, 1991, the last oil fire in Ku-
 wait was extinguished, bringing to a close a dra-
 matic period of achievement.  Extinguishing and
 capping these wellheads had been Kuwait's highest
 economic, environmental, and health priority be-
 cause of feared regional and global consequences.
 International cooperation, skill, and expertise re-
 sulted in a more rapid end  to one part of this
 environmental catastrophe.
   Attacks on the environment began in late Janu-
 ary, 1991,  when the Iraqi government  ordered
 millions of barrels of crude oil released into the Gulf
from tankers and oil terminals located off the coast
 of occupied Kuwait. Less than a month later, as
 Iraq's armies were driven from that country, they
 blew up hundreds of Kuwaiti oil wells, setting most
 of them ablaze.
   In every war there is damage to the environ-
 ment. But discharging the oil and ignitingthe wells
 had neither economic nor military  benefit. The
 Iraqi government waged war against the envi-
 ronment itself , producing images of blackened wa-
 ters and skies now burned into the memory of the
 world community.
   This booklet answers the questions  most often
 asked by Americans about potential effects of this
 disaster on the environment and on  the health of
 residents of the Gulf region,  including American
 military and civilian personnel stationed there.
 The booklet briefly  describes  work performed by
U.S. government agencies, in cooperation with
allied Gulf nations and the international commu-
nity, to try to assess, limit, and remedy the damage
caused by Iraq's environmental terrorism.
   Since April 1991, officialU.S. actions have been
in concert with international programs responding
to the oil release and addressing atmospheric prob-
lems from the burningfires. Private U.S. compa-
nies helped to extinguish the fires, clean up refuse,
repair damage from the war and Iraqi vandalism,
and respond to the Gulf oil release.
   Even as the air, sea, and ground battles were
waged in January and February 1991, the United
States, through its multi-agency Emergency Re-
sponse Team and other units, began mapping the
spread of the oil discharges andmobilizingscientific
teams to evaluate and mitigate environmental
damage in the Gulf. Some of the data collected are
still being analyzed, and more are being gathered.
Some findings reported here should therefore be
considered preliminary.
   While outside of the scope of this report, the U.S.
Army Corps of Engineers must be cited for its work
in helping to rebuild Kuwait's infrastructure in-
cluding restoration of roads, electrical power, sewer
and water systems, the airport, and public build-
ings. Without these basic systems and the efforts of
the Corps, the environmental efforts described be-
low would have been difficult to achieve as quickly.

     The unprecedented number of oil fires challenged fire-fighting resources at the outset, but
   as more crews were brought in, and new techniques honed, the flames were snuffed out far
   more quickly. Graphic by Jean Wisenbaugh.

About nine months - far faster than many had
expected. The  rate at which the fires were
extinguished climbed from one every few days in
the early weeks to seven a day in the fall.

   On February 15, 1991, the retreating Iraqi
army began systematically dynamiting oil wells,
storage tanks, refineries, and other facilities lo-
cated in seven oil fields north and south of Kuwait
City (see map). Approximately three-quarters of
the facilities in these fields—a total of 749—were
either set on fire, turned into oil gushers or other-
wise damaged. An estimated nine hundred mil-
lion barrels were burned or spilled onto the land
during these 9 months, enough oil to supply the
United States for 50 days.
   Firefighting teams  from the  United  States,
Canada, Kuwait, and later other nations, worked
steadily to douse the fires  and cap the  gushing
wells. The work was made even more difficult by
explosives surrounding the wells and by the scar-
city of water, which  had to be pumped in from
miles away.
   Nonetheless, once the equipment was in place
and the firefighting  teams  gained more  experi-
ence, the work progressed far faster than originally
expected. (Some had estimated it would take up to

five years to control the fires.) While by mid-May,
just 80 of the burning wells had been extinguished,
half were out by August, and by early November,
the last of the fires were doused.
   With over 80% of the world's oil-fire fighting
expertise in Kuwait, this disaster spawned ingenu-
ity and competition among the international teams.
Tested methods were measured against new tech-
nologies including jet engines mounted on tanks
to "blow" the  fires out and liquid nitrogen to
displace oxygen, suffocating the flames.
           HOW WIDESPREAD WAS
           THE POLLUTION FROM
                    THE FIRES?
          The consensus  of the international scientific
          community is that airborne emissions from the
          fires primarily affected southern Kuwait and a
          200 mile stretch of eastern Saudi Arabia. Ef-
          fects beyond the Gulf region have been slight.

            As the fires burned, they threw soot particles,
          chemical pollutants, and other emissions into the
          air.  Carried aloft by the force of the heat, these
          emissions drifted away in dense plumes of smoke.
          Most of the large, heavier droplets of unburned
          oil, fell out of the smoke plume quickly and did not

travel tar from the oil fields. Other, lighter pollut-
ants were blown hundreds ot miles by winds.
   Because Iraqi troops had stolen most of Kuwait's
air pollution monitoring equipment and destroyed
its major laboratories, scientists from the United
States and several other nations rushed equipment
to the scene soon after the fires were set. Science
teams from England and  the  U.S.  sampled the
contents  of the  smoke  by flying aircraft with
sophisticated instruments  as near to the  fires as
they safely could (within a few hundred yards) and
as far away as 600 miles from the source  of the
smoke. Ground stations throughout the Gulf re-
gion also took air samples. Kuwaiti stations were
supplemented by equipment from France, Ger-
many, Japan, Norway, and the United States.
   During the spring and summer, prevailing winds
from the north and breezes off the Gulf generally
kept the plumes aloft and moving south over the
desert, away from Kuwait City, the nearest popu-
lation center.  The plumes combined and were
carried over eastern  Saudi Arabia and Bahrain.
   The smoke dimmed sunlight, apparently pro-
ducing cooler regional temperatures for a period.
Bahrain, for example, experienced  its coldest May
in 35 years with temperatures more  than  7.2° F
below average for that month. As the fires were
extinguished,  however, this local cooling effect
diminished.
   Not long after the fires  were set, "black snow"
reportedly fell in the Kashmir region of northern
India, and sooty rain was reported in nearby Iran.
There were reports of very small amounts of soot
particles high in the air over Hawaii and Wyo-
ming, but these anecdotal observations could not
be positively linked to the Kuwait fires. Overall,
there has been no clear evidence that the  oil tire

-------
emissions traveled beyond the region in signifi-
cant amounts. Combustion products  from  the
fires may still be detectable in trace amounts at
great distances, however, as they were expected to
remain in the atmosphere for several weeks.
   Some computer models predicted that sulfur
dioxide from the fires could lead to acid rain in
Kuwait, Iran, and even as far away as China. The
lack of rainfall in the Gulf during the time when
the fires were burning minimized that potential
problem.
   While new emissions are no longer spewing
into the atmosphere now that the fires have been
extinguished, pollution already deposited may still
be blown around  by winds. Monitoring of the
region's air quality and weather must continue.
  HAS SMOKE FROM  THE

   OIL FIRES AFFECTED
     GLOBAL  CLIMATE?

There is no evidence that the emissions reached
altitudes hiffh  enough to be carried  by winds
around the globe.
   Material that reaches the stratosphere can be
dispersed around the globe by high-altitude winds.
But satellite images, along with observations and
air sampling from aircraft, have shown that the oil
fire smoke generally rose to altitudes of  12,000 to
                                                                   Stratosphere
                                                                   "Troposphere
13,000 feet, with a maximum observed height of
19,000 feet, well below the 40,000-foot lower
limit of the stratosphere. As one researcher from
the National Center for Atmospheric Research
put it, "As large as the smoke looks, and as ugly as
it is, it's still pretty small on a global scale."
   By contrast, smoke from the June 1991 erup-
tion of Mt.  Pinatubo in the Philippines lofted
millions of tons of sulfur dioxide and dust well into
the stratosphere, where it has spread around the
globe. Mt. Pinatubo's material is expected to re-
main in the stratosphere for years, possibly even
having a  very slight worldwide cooling effect.
Some parts of the world may witness particularly
vibrant sunsets as a result of sunlight reflecting off
the dust particles.
   For the oil fires, however, research proved false
an initial  speculation that plumes would self-loft
into the stratosphere causing cooling analogous to
the "nuclear winter" scenario. There are several
reasons why emissions from the oil fires did  not
reach these altitudes. They were not thrown up-
ward with great enough force, as in the case of a

  Under a desert sun partially masked by smoke from oil fires, a U.S. scientist installs air-
monitoring equipment atop a plane. In the spring of 1991, specially equipped aircraft flew over
the Gulf region to examine air pollutants and wind patterns as part of an international, multi-
agency environmental assessment. Two planes were supplied by the University of Washing-
ton and the National Center for Atmospheric Research, through a U.S. National Science
Foundation program conducted with the assistance of the National Geographic Society.
Another aircraft, supplied by the Department of Energy, sampled the plumes a month later
during different meteorological conditions. In addition, a helicopter, supplied and operated by
the Saudi Arabian Air Force, lifted off from Kuwait City airport, carrying scientists from the
National Aeronautics and Space Administration, Environmental Protection Agency, Kuwait
and Saudi Arabia. The multi-national team flew next to blazing wells to gather emission
samples later evaluated by a number of U.S. government scientists.  Photo by National

   At the request of the Saudi government, the
U.S. InteragencyAir AssessmentTeam (USIAAT)
was dispatched to the Gulf soon after the fires were
started to assess the immediate, acute health threat.
This "quick look," conducted from March through
May 1991, involved researchers from several U.S.
government agencies. The team sampled air near
the burning  wells,  flew instrumented airplanes
into smoke plumes, and sampled the air at various
locations  in  the  path of the smoke,  including
population centers in Kuwait and Saudi Arabia.
   Based on  this limited preliminary study,  the
team publicly reported in  April  that emissions
from the oil fires were not immediately life-threat-
ening. The ingredients of the smoke plumes varied
from fire to fire, but in general they were the same
pollutants  one might  find  in the exhaust  of a
poorly functioning automobile: soot particles; or-
ganic compounds; trace metals; and gaseous pol-
lutants such as sulfur dioxide, hydrogen sulfide,
and carbon monoxide.
   The USIAAT paid particular attention to mea-
suring hydrogen sulfide, sulfur dioxide, and fine
soot particles in the smoke, which are known acute
health hazards at high concentrations. The two

      Air monitoring in Kuwait City showed some anomalies: some pollutant levels were lower
    this spring than the year before, apparently because the Iraqi invasion had stopped most
    industrial activity and civilian vehicle use. These charts compare the levels of fine particulates
    (PM-10), sulfur dioxide, and nitrogen dioxide for the 1991 April to September average in
    Kuwait City to Los Angeles' 1989 levels and to EPA standards for annual average 24-hour
    readings. A very high PM-10 reading in Kuwait City is usual for that region, the result of
    blowing dust and sand.
health hazard—hydrogen sulfide and sulfur diox-
ide—were determined to be present in concentra-
tions below the harmful levels established by EPA
for the United States, both near the source of the
fires and at locations  sampled  downwind. The
USIAAT  measured high concentrations of par-
ticles in the smoke, however, which remained a
cause for concern while the fires  were burning.
Under certain weather conditions  these fine par-
ticles can cause respiratory problems for individu-
als with asthma and other obstructive lung dis-
eases,  as well as other "high-risk" population
groups—including the elderly, children, and preg-
nant women.
   Subsequent studies supported the findings of
the USIAAT. An air  sampling mission in May
and June, sponsored by the U.S. National Science
Foundation (NSF), found  that hydrogen sulfide
was being burned quickly in the fires, as it did not
appear in significant concentrations in the smoke.
As for  sulfur dioxide, the  NSF team measure-
ments showed small amounts but  not enough to
cause a significant acute health threat to popula-
tions in the path of the smoke, since winds tended
to reduce the concentration.
   The USIAAT also reviewed Saudi and Kuwaiti
air quality and meteorological data, and evaluated
the local health care system's ability to deal with
potential acute  effects from the fires. The U.N.
prepared an interagency strategy for air monitor-
ing in the  area and air quality is still being moni-
tored continuously at sampling stations through-
out the Gulf region.
   The number of air quality and weather moni-
toring stations are to be increased beyond what
was in place prior to the hostilities and the 15 to 20
portable stations left behind by the U. S. air assess-
                                                                10

ment team. In addition, an "early warning sys-
tem," developed by the U.S. National Oceanic and
Atmospheric Administration and other agencies
was placed in Kuwait to alert the local population
if severe pollution levels posed a significant health
threat. Public education programs also were cre-
ated to inform local citizens about potential haz-
ards from airborne pollutants.
      WITH ALL THOSE
   POLLUTANTS IN THE
 SMOKE, WHY WEREN'T
        MORE HEALTH
 PROBLEMS REPORTED?
The most severe levels of pollution were found in
the plumes far above ground level, and weather
patterns generally kept the smoke away from
population centers.

   Early in the crisis, there were predictions from
some observers that the fires would have cata-
strophic health effects. But the nature and amount
of pollution in the smoke, the behavior of the
plumes in the atmosphere, and local weather con-
ditions served to limit the impact of the fires on the
human population.
  The largest particles and oil droplets from the
     IF THINGS  HAD BEEN DIFFERENT...

      Even though there is no evidence to date that smoke from the
   Kuwaiti oil fires created acute health problems, air pollution can be
   deadly under certain conditions.
      In October 1948,  severe pollution over the town of Donora,
   Pennsylvania resulted in 20 deaths—17 in a single 14-hour period.
   A high pressure area kept winds to a minimum for several days
   straight, allowing a cold, dense fog containing sulfur dioxide, fine
   particles, and carbon monoxide to linger in the industrial valley
   where Donora is located.
      A more severe episode occurred in London in December 1952,
   when a thick, four-day fog resulted in thousands of deaths due to
   inhalation of particles and sulfur dioxide.
      In both these cases, dense, polluted air remained trapped over
   a populated area for several days. Fortunately, this was never the
   case in Kuwait. Prevailing winds effectively dispersed smoke from
   the oil fires during the time when most of the wells were burning,
   and most fires were extinguished before the beginning of the winter
   season when weather inversions would have been more likely to
   cause extended periods of stagnant air over Kuwait City. Also, a
   key pollutant in the Donora and London  episodes—sulfur diox-
   ide—did not appear in high concentrations in the smoke over the
   Gulf.
fires fell out of the smoke relatively near to the
burning wells, in areas that were largely uninhab-
ited. The spread of other, lighter airborne pollut-
ants was determined by daily and seasonal local
weather patterns. Winds thinned  the smoke,
thereby reducing the concentration of pollutants,
and also kept the plume away from Kuwait City.
Breezes from the Gulf itself helped protect other
shoreline population centers. Thus, Kuwait City
rarely was exposed to the plume for more than 48
hours at a time, even though the nearest oil field is
less than two miles from the city's suburbs.

                                                                        TERM HEALTH
                                                                            EFFECTS?
The unique nature of the situation—intermit-
tent exposure to pollution from a  large yet
declining number of fires—will make long-term
health assessments extremely difficult. Research
and health studies are continuing.

  Long-term health effects from air pollution are
determined primarily by the amount of exposure,
which considers not only the concentration of a
pollutant, but the length of time individuals are
exposed to it. There were only a few days in which
the  population was subjected to high levels of
pollution from the fires.
  One problem in identifying long-term effects is
that natural or normal  "background" causes of
disease and mortality first have to be factored out.
Fine soot particles from the fires are of major
concern because they can penetrate deeply into the
lungs. But since Kuwait and Saudi Arabia are
prone to sandstorms, the air normally carries ex-
tremely high levels of airborne particulates. Re-
searchers  must first examine long-term health
data on the local population to find what is "usual"
before  determining if there have been changes
from the fires. For example, Kuwaitis are known
to have a high incidence of asthma.
  Scientists also must have a full understanding
                                                   12

of which substances actually reached the people,
and in what amounts. As part of the World Health
Organization's plan for dealing with effects of the
oil fires, a formal study is  being conducted in
Kuwait to determine whether local populations
are being exposed to higher levels of fine particles
in the air.
  Included in the particulate matter emitted by
the oil fires were polycyclic aromatic hydrocarbons
and trace metals  such as nickel, chromium and
vanadium, which  are known  or suspected cancer-
causing  agents. These  were detected in  small
amounts in smoke and soils near the source of the
fires, but not at sampling stations located down-
wind.
     WHAT ABOUT THE
       HEALTH OF  U.S.
         TROOPS AND
           CIVILIANS?

There has  been no evidence of fire-related
health problems occurring among U.S. military
or civilian personnel assigned to the region.
   A survey by the U.S. Navy of 2,700 Marines
serving in the  Gulf theater found no increase in
sick call rates  based  on proximity to the fires.

region did not indicate a significant likelihood of
long-term health effects. Military personnel gen-
erally are not in those groups considered to be
highly susceptible to the effects of pollution—the
very young,  the elderly and  those with severe
asthma.
   The U.S. Army is continuing its air monitoring
activities, in addition to the civilian monitoring at
existing regional sampling stations, as long as U.S.
military personnel are in the region. Furthermore,
new civilian and military personnel being assigned
to the area, including  those conducting environ-
mental research, are being examined before depar-
ture from the U.S. to determine the status of their
health. They will be examined again  after their
stay in the Gulf region to determine if the pollu-
tion has any health effects. Naturally, as the fires
were extinguished,  the potential for such effects
diminished.

                                                               UP?
Over a million barrels of oil were removed from
the Gulf by April. One third of the total released
is estimated to  have evaporated. Despite this
record recovery of surface oil and significant
evaporation,  much of the oil sank, and about
400 miles of the western shoreline of the Gulf is
contaminated with congealed oil.

  In January 1991, Iraq dumped an estimated six
to eight million barrels of oil into the upper Gulf
from tankers and terminals located off the coast of
Iraq and Kuwait. Military actions produced some
smaller additional spillage.
  Taken as a whole, the Gulf release ranks among
the largest in history, up to 30 times the amount of
oil spilled in the 1989 Exxon Valdez accident.  A
substantial amount of soot and oil from the well
fires also  fell into the Gulf waters while the fires
were burning, adding to the pollution from the oil
spill. The total amount of contaminants and their
effects are unknown.
  The then-ongoing war  limited but did not
prevent all actions to stop the flow of oil at the time
of release: Kuwaiti employees at the  Mina Al
Ahmadi facility secretly closed the valves to one
group of  storage tanks to prevent release of mil-
lions of additional barrels of oil. Later,  coalition

aircraft were able to use "smart bombs" to cut off
much  of the flow from  the Mina  Al Ahmadi
facility off Kuwait, the source of the main release.
   The released oil, carried by tides and currents
and driven by prevailing winds, moved southward
to  Saudi Arabia.  Shortly after the oil was first
detected, that country  requested technical assis-
tance from  the United States, which sent a U.S.
Coast Guard-led team to the Gulf to help assess
the oil slick's magnitude and impact. Despite the
hostilities, daily overflights by scientists  and the
military, satellite imagery and onshore sightings
helped track the oil's progress, and U.S. advisors
assisted Saudi officials in planning  a response
strategy.
   The slick covered an estimated  600  square
miles of sea surface. Under the provisions of Saudi
Arabia's National Oil Spill Contingency Plan, the
highest priority for early protection was the desali-
nation plant at Jubayl. The largest such facility in
the world, Jubayl provides the Saudi capital of
Riyadh with 80 percent of its water. Work crews
successfully protected the plant by installing booms
around inlet areas and skimming oil from the
surface. The crews also were able to protect other
desalination plants, power plants, and oil facilities
designated as high priorities.
   The initial clean-up operations were aimed at
recovering free-floating oil from the  water's sur-
face. Using skimming vessels under contract to the
Saudi-owned oil  company, ARAMCO,  crews
isolated sections of the spill and scooped  an un-
precedented 1.4 million  barrels of oil from the
waters by mid-April. One third of the oil released
is thought to have evaporated naturally from the
surface of the water. Much sank to the bottom of
the Gulf.

ment, cleaning, and
absorption material was
brought to the Gulf (left).

inlets for critical water

  Along the western shoreline, crews contracted
by the Saudi  government, using containment
booms trom several nations and guidance from the
Coast Guard and ARAMCO, scavenged oil from
bays where it collected naturally and built berms
extending out from the shore to capture even
more. The crews dug trenches to trap oil riding in
on tides, and pumped the collected oil into con-
tainment pits. Despite these efforts, oil contami-
nated much ot  the shoreline, with the area be-
tween Safaniya and Abu Ali Island in Saudi Arabia
bearing the worst pollution. On this stretch of the
coast, which also was severely affected by a spill
trom an oil field in 1983, tarballs appear on the

   The rich ecosystem in these shallow waters
includes salt marshes, mangrove swamps, beds of
sea grass, and intertidal mud flats where fish and
animals feed on algae. Coastal wetlands and is-
lands provide nesting areas for many native and
migratory birds, including flamingos and the en-
dangered Socotra Cormorant. The oil also threat-
ened shellfish, turtles, and coral.
   Due to the size of the release and the impossi-
bility of a full response  during  the war,  many
ecologically sensitive areas could not be protected.
There  were private wildlife rescue projects that
saved some fowl and turtle nesting areas, but many
shore birds fell victim to the oil slick. Some species
of wildlife in the Gulf have shown remarkable
resiliency following major oil spills in  the past.
Unfortunately, the most  heavily  polluted  salt
marshes are unlikely to survive, which surely will
reduce bird populations. While coral in shallow
water shows the black stain of oil that sank below
the surface, coral in deeper water apparently are
not severely contaminated. Deep water fish are
expected to fare better than marine life that spawns
and feeds in shallow water.

the coastline by Saudi and U.S. scientists, a data-
base ranking the most ecologically sensitive areas

        WHAT OTHER

     ENVIRONMENTAL

   DAMAGE HAS THERE

              BEEN?

Oil pooling on the ground near the burning
icells, rate seicage pouring into the Gulf, and
disruption of desert plant life and surface soil
are additional ecological concerns facing the
region.

   Millions of barrels of crude oil (estimates range
from 10 to 100 million barrels) spilled onto the
ground from wells damaged but not successfully
ignited by the Iraqis. The spills formed ponds,
some of which were ignited by nearby burning
wells, adding more smoke and pollutants to the air
and blackening the desert in the immediate vicin-
ity
   Near the source, a large amount of the oil
remained unburned, forming more pools. Some
oil, baked by nearby fires, hardened into asphalt on

enough to reach freshwater underground aquifers.
Kuwaiti officials are surveying the oil  pools  to
assess potential ecological damage and possibili-
ties for recovering the oil. The unhardened pools
also represent a  continuing hazard to  wildlife,
particularly for birds who mistake the oil ponds for
water.
   In addition, unburned oil droplets from the
smoke have  coated mangroves and other wild
plants  in southeast Kuwait. The  level  of plant
mortality and the ability of the plants to recover are
not yet known; in some areas new growth already
has been spotted.
   Also uncertain is the extent of the damage to
the desert surface.  The damage comes not only
from oil, but also from the movements of thou-
sands of heavy military vehicles and from the Iraqi
Army's  digging of trenches. One concern is that,
because the desert's natural crust has been broken
by these multiple impacts, more severe sandstorms

and movement of sand dunes could result.
  The disposal of unexploded military munitions and of
chemicals from damaged industrial plants created further
burdens, as did Iraqi sabotage of sewage treatment plants,
which increased the amount of raw sewage dumped into
the  Gulf until the plants could be repaired.  Massive
amounts of waste still litter the landscape and range from
asbestos construction debris to PCB's from damaged
power stations.
    WHAT ROLE WILL GULF
 NATIONS AND THE UNITED
      STATES PLAY IN  THE
            CONTINUING
    ENVIRONMENTAL AND
         HEALTH ISSUES?
The Gulf nations have taken responsibility for clean-up
and recovery operations; the United States continues
to provide technical assistance in accordance with
international response plans and requests from gov-
ernments in the region.

   U.S. government efforts have evolved from  initial
emergency response to helping Kuwait and Saudi Arabia
address medium- and long-term recovery. For example,
the United  States helped  reestablish and expand air
quality and weather monitoring systems so that local
authorities were alerted about possible incidents of severe
air pollution. Those authorities could then take, or urge
residents to take, actions to reduce the pollution levels or
exposure.
    The U.S.  offered this technical assistance in part
because Kuwait's scientific  infrastructure  was severely
damaged during the Iraqi occupation. The United States
supplied Kuwait with monitoring equipment to replace
equipment stolen or destroyed by Iraq, and has provided
considerable scientific expertise as well. By October 1991,
the U.S. government had spent  nearly S10 million on
health and environmental protection activities in the
Gulf. (This amount does not include the  time of U.S.
personnel.)
  Although scientists have preliminary data on the  ef-
fects of the fires and oil discharges, there is more to be
learned.  For example, the U.S.  has proposed sending
public health experts to the area to try to determine the
effects oil soot and droplets may have on local food
supplies, including marine life. Other U.S. government
personnel are advising Kuwaiti scientists measuring the
amount of small particles, outdoors and indoors, that
could be inhaled by local residents. U.S. government
agencies also may be involved in more scientific research
on the effects of the shoreline oil. A complete understand-
ing of the severity of the threats to public health and the
environment will take many months, even years.
   This investment of U.S. government time and  re-
sources to date  reflects the concern of our citizens for the
human health  and  environment of  Kuwait and  Saudi
Arabia. When  all is said and done, by helping the Gulf
region respond to this disaster, the community of nations
can learn new strategies and new methods for coping with
future environmental crises. If we do, and if we encourage
new modes of regional and international cooperation,
then we will have drawn what benefits we could from this
human and environmental tragedy.
