Atmospheric and localized anthropogenic impacts on subarctic, boreal, and prairie aquatic ecosystems

Contributes to knowledge on levels, sources, and movement of  chemicals concern including POPs, mercury, and hydrocarbons for use  in Canadian and international risk assessment and management  programs.  Also contributes to information on time trends.   Information used by CACAR, AMAP and UN in understanding how  contaminants enter aquatic ecosystems, their pathways, and how  aquatic ecosystems are responding to reduced inputs through various  bans.  Information also used to allow industry to further develop  (e.g., oil sands, pulp and paper mills) while protecting the aquatic  environment. Funding comes from Northern Contaminants Programs and  other EC Initiatives (NREI, NEI). Activities: 1. Investigate mercury, water chemistry, and food relationships in a  series of lakes in the NWT.  In addition to new collections, work  with large data sets generated by DFO-Winnipeg.  2. Complete the analysis of mercury and POPs data collected as part  of the Muir-led TSRI project.  No new sampling is proposed.  These  data will be worked up into reports to be provided to Alberta  Environment and SERM with a focus on the special issues of interest  to the two provinces.   3. Continue Great Slave Lake and Slave River contaminant (mercury,  POPs) monitoring project for predatory fish and analyze these data  along with historic biological and sediment data.  Data collected in  1999 suggests a decline in POPs in fish in the East Arm but not the  West Basin.  This will be further investigated with the receipt of  data for 2    and 2  1 caught fish.  4. Earlier biological POPs data collected on Great Slave Lake will be  prepared into a scientific manuscript. Sediment POPs data also will  be worked up.  5. Complete analysis of hydrocarbon data collected as part of the  PERD project and the ongoing RAMP monitoring program.  Also complete  analysis of hydrocarbon data for Great Slave Lake studies conducted  in the 199 s.  This includes surface sediment and coring studies.  6. Analyze biological and contaminant (mercury, POPs) data collected  at 6 sites on the Peace and Athabasca Rivers in September 2  1 to  assess impacts of nutrients and contaminants on POPs  biomagnification.  8. Complete analysis of zooplankton samples collected over 2    and  2  1 in Hamilton Harbor.  Assess community responses relative to  nutrient and contaminant inputs.  Also assess presence of disease in  the zooplankton populations.
