                 Update: Listing of Fish and Wildlife Advisories
  
  Summary
  
  The 1996 update for the database, Listing of Fish and Wildlife Advisories
  (LFWA), is now available from the U.S. Environmental Protection Agency
  (EPA). This database includes all available information describing state-,
  tribal-, and federally issued fish consumption advisories in the United
  States for the 50 States, the District of Columbia, and four U.S.
  Territories, and has been expanded to include the 12 Canadian provinces and
  territories. The database contains information provided to EPA by the
  states, tribes, and Canada as of December 1996. This includes advisories
  issued by several Native American tribes. The number of advisories in the
  U.S. rose by 453 in 1996 to a total of 2,193, representing a 26% increase
  over 1995. The number of waterbodies under advisory represents 15% of the
  Nation's total lake acres and 5% of the Nation's total river miles. In
  addition, 100% of the Great Lakes waters and their connecting waters and a
  large portion of the Nation's coastal waters are also under advisory. The
  number of advisories in the U.S. increased for four major contaminants
  (mercury, PCBs, chlordane, and DDT).
  
  In 1996, the U.S. EPA contacted health officials in Canada in an effort to
  identify fish consumption advisories in effect. In Canada, a total of 2,617
  advisories were in effect in 1996. All of the Canadian advisories resulted
  from contamination from five pollutants: mercury, PCBs, dioxin/furans,
  toxaphene, and mirex. Ninety-six percent of all the advisories resulted from
  mercury contamination in fish tissues. In addition, 87% of the advisories
  were issued by the provinces of Ontario and Quebec.
  
  Background
  
  The states and the four U.S. Territories and Native American tribes
  (hereafter referred to as states) have primary responsibility for protecting
  their residents from the health risks of consuming contaminated
  noncommercially caught fish and wildlife. They do this by issuing
  consumption advisories for the general population, including recreational
  and subsistence fishers, as well as for sensitive subpopulations (such as
  pregnant women, nursing mothers, and children). These advisories inform the
  public that high concentrations of chemical contaminants (e.g., mercury and
  dioxins) have been found in local fish and wildlife. The advisories include
  recommendations to limit or avoid consumption of certain fish and wildlife
  species from specific waterbodies or, in some cases, from specific waterbody
  types (e.g., all lakes). Similarly, in Canada, the provinces and territories
  have primary responsibility for issuing fish consumption advisories.
  
  States typically issue five major types of advisories and bans to protect
  both the general population and specific subpopulations (usually pregnant
  women, nursing mothers, and young children). When levels of chemical
  contamination pose a health risk to the general public, states may issue a
  no consumption advisory for the general population (NCGP). When contaminant
  levels pose a health risk to sensitive subpopulations, states may issue a no
  consumption advisory for the sensitive subpopulation (NCSP). In waterbodies
  where chemical contamination is less severe, states may issue an advisory
  recommending that either the general population (RGP) or a sensitive
  subpopulation (RSP) restrict their consumption of specific species for which
  the advisory is issued. The fifth type of state-issued advisory is the
  commercial fishing ban (CFB), which prohibits the commercial harvest and
  sale of fish, shellfish, and/or wildlife species from a designated waterbody
  and, by inference, the consumption of all species identified in the fishing
  ban from that waterbody. As shown in Table 1, all types of advisories
  increased in number from 1993 to 1996.

  Advisories in Effect
  
  The database includes information on
  
     + Species and size range of fish and/or wildlife
     + Chemical contaminants identified in the advisory
     + Geographic location of each advisory (including landmarks, river miles,
       or latitude and longitude coordinates of the affected waterbody)
     + Lake acreage or river miles under advisory
     + Date the advisory was issued
     + Percentage of waters assessed by states for fish advisories.
  
  The 1994, 1995, and the new 1996 versions of the LFWA database can generate
  national, regional, and state maps that illustrate any combination of these
  advisory parameters. In addition, the 1996 database can provide information
  on the percentage of waterbodies in each state that is currently under an
  advisory and the percentage of waters assessed. The name of each state
  contact, a phone number, and FAX number are also provided so that users can
  obtain additional information concerning specific advisories. Comparable
  advisory data and contacts for 1996 are provided for each Canadian province
  or territory.
  
  Advisory Trends
  
  The number of waterbodies in the U.S. under advisory reported in 1996
  (2,193) represents a 26% increase from the number reported in 1995 (1,740
  advisories) and a 72% increase from the number of advisories issued since
  1993 (1,278 advisories). The increase in advisories issued by the states
  generally reflects an increase in the number of assessments of the levels of
  chemical contaminants in fish and wildlife tissues. These additional
  assessments were conducted as a result of the increased awareness of health
  risks associated with the consumption of chemically contaminated fish and
  wildlife. Figure 1 shows the number of advisories currently in effect for
  each state and the increase or decrease in the number of advisories since
  1995. The number of advisories decreases if states determine that monitored
  concentrations of chemical contaminants in fish or wildlife tissues have
  decreased and no longer pose a risk to human health.

  Bioaccumulative Pollutants
  
  Although advisories in the U.S. have been issued for a total of 45 chemical
  contaminants, most advisories issued have involved five primary
  contaminants. These chemical contaminants are biologically accumulated in
  the tissues of aquatic organisms at concentrations many times higher than
  concentrations in the water. In addition, these chemical contaminants
  persist in sediments for relatively long periods where they can be
  accumulated by bottom-dwelling animals and passed up the food chain to fish.
  Concentrations of these contaminants in the tissues of aquatic organisms may
  be increased at each successive level of the food chain. As a result, top
  predators in a food chain, such as trout, salmon, or walleye, may have
  concentrations of these chemicals in their fatty tissues that can be a
  million times higher than the concentrations in water. Mercury, PCBs,
  chlordane, dioxins, and DDT (and its degradation products DDE and DDD) were
  responsible for almost 95% of all fish consumption advisories in effect in
  1996. This pattern was also seen in the 1993, 1994, and 1995 databases (see
  Figure 2).

  Mercury
  
  Advisories for mercury increased 28% from 1995 to 1996 (1,308 to 1,675) and
  increased 86% from 1993 to 1996 (899 to 1,675). The number of states that
  have issued mercury advisories also has risen steadily from 27 to 34 to 35
  to 38 in 1993, 1994, 1995, and 1996, respectively. The rise in the number of
  mercury advisories in 1996 can be attributed primarily to issuance of new
  mercury advisories in 12 states. The majority (89%) of these new advisories,
  however, were issued in four states: Wisconsin (153), including 99 by the
  Chippewa Tribes, Indiana (108), Minnesota (50), and Massachusetts (17).
  
  It should also be noted that nine states (Connecticut, Florida, Indiana,
  Maine, Massachusetts, Michigan, New Hampshire, New Jersey, and Vermont) have
  issued statewide advisories for mercury in certain waterbody types (e.g.,
  lakes). To date, 90% of the 1,675 mercury advisories in effect have been
  issued by the following 10 states: Minnesota (693), Wisconsin (389), Indiana
  (116), Florida (94), Michigan (41), North Dakota (35), Massachusetts (34),
  New Jersey (30), New Mexico (26), South Carolina (24), and Georgia (23).
  
  PCBs
  
  Similarly, advisories for PCBs increased 41% from 1995 to 1996 (438 to 616)
  and increased 93% from 1993 to 1996 (319 to 616). The number of states that
  have issued PCB advisories increased only slightly from 31 to 35 states from
  1993 to 1994 and then declined to 34 states in 1995. The rise in the number
  of advisories for PCBs in 1996 (178) can be attributed to the issuance of
  new advisories by nine states. The majority (87%) of these 178 new
  advisories, however, were issued by three states: Indiana (114), Wisconsin
  (28), and Minnesota (12). To date, 84% of the 616 PCB advisories have been
  issued by 11 states: Indiana (134), Minnesota (125), Michigan (52),
  Wisconsin (52), New York (49), Georgia (21), Nebraska (19), Ohio (21),
  Pennsylvania (18), Massachusetts (17), and New Jersey (12). Seven states
  (Connecticut, District of Columbia, Indiana, Missouri, New Jersey, New York,
  and Rhode Island) have issued statewide advisories for PCBs, including three
  for marine waters. Only two of these statewide PCB advisories (District of
  Columbia and Rhode Island) are for PCBs only, however.
  
  Other Pollutants
  
  The total number of advisories for chlordane and DDT (and its degradation
  products) increased negligibly <1% and 3% from 1995 to 1996, respectively.
  The total number of advisories for dioxins was 54 in 1993, then rose to 63
  in 1994, held steady at 63 in 1995, and declined to 60 advisories in 1996.
  Dioxins are one of several chemical contaminants for which advisories have
  been rescinded by some states, in part because many pulp and paper mills
  have changed their processes.
  
  Wildlife Advisories
  
  In addition to advisories for fish and shellfish, the database also contains
  several wildlife advisories. Four states have issued consumption advisories
  for turtles: Arizona (3), Massachusetts (1), Minnesota (5), and New York
  (statewide advisory). One state (Massachusetts) has an advisory for frogs,
  New York has a statewide advisory for waterfowl (mergansers), and Arkansas
  recently issued an advisory for woodducks. Maine issued a statewide advisory
  for moose liver and kidneys due to cadmium levels.
  
  1996 Advisory Listing
  
  The 1996 database lists 2,193 advisories in 47 states, the District of
  Columbia, and the U.S. Territory of American Samoa. Some of these advisories
  represent statewide advisories for certain types of waterbodies (e.g.,
  lakes). An advisory may represent one waterbody or one type of waterbody
  within a state's jurisdiction. Statewide advisories are counted as one
  advisory. The database counts one advisory for each waterbody name or type
  of waterbody regardless of the number of fish or wildlife species that are
  affected or the number of chemical contaminants detected at concentrations
  of human health concern. Thirteen states (Florida, Connecticut, Indiana,
  Maine, Massachusetts, New Hampshire, New Jersey, New York, Michigan,
  Missouri, Rhode Island, Vermont, and the District of Columbia) currently
  have statewide advisories in effect. A statewide advisory is issued to warn
  the public of the potential for widespread contamination of certain species
  of fish in certain types of waterbodies (e.g., lakes or coastal marine
  waters). In such a case, the state may have found a level of contamination
  of a specific pollutant in a particular fish species over a relatively wide
  geographic area that warrants advising the public of the situation.
  
  The 13 statewide advisories and 2,193 specifically named waterbodies
  represent approximately 15% of the Nation's total lake acreage and 5% of the
  Nation's total river miles. In addition, 100% of the Great Lakes waters and
  their connecting waters and a large portion of the Nation's coastal waters
  are also under advisory. The Great Lakes waters are considered separately
  from other lakes, and their connecting waters are considered separately from
  other river miles. The percentages of lake acres and river miles in each
  state that are currently under a fish advisory are shown in Figures 3 and 4,
  respectively.

  Summary of Canadian Advisories
  
  Beginning in 1996, the U.S. EPA contacted health and environmental officials
  in the 12 Canadian provinces and territories to obtain narrative and
  geographic information systems (GIS) information on advisories throughout
  Canada. The number of Canadian advisories in effect in 1996 was 2,617. This
  includes one provincewide advisory for mercury for Nova Scotia. Figure 5
  shows the number of waterbodies under advisory for each of the Canadian
  provinces. Ontario and Quebec reported the highest number of advisories,
  1,552 and 712, respectively. Based on all the advisories reported, 87% were
  issued for waterbodies in these two provinces. With respect to chemical
  contaminants, advisories in Canada have been issued for a total of five
  bioaccumulative chemical contaminants including mercury, PCBs,
  dioxins/furans, toxaphene, and mirex. More than 96% of all Canadian
  advisories have been issued for mercury.

  Database Use and Access
  
  The database was developed by EPA to help federal, state, local government
  agencies, and Native American tribes assess the potential for human health
  risks associated with consumption of chemical contaminants in
  noncommercially caught fish and wildlife. The data contained in this
  database may also be used by the general public to make informed decisions
  about the waterbodies in which they choose to fish or harvest wildlife; the
  frequency with which they fish these waterbodies; the species, size, and
  number of fish they collect; and the frequency with which they consume fish
  from specific waterbodies.
