This study investigated methylmercury (MeHg) concentrations in Arctic benthic invertebrates from two shelf sites in the Canadian Beaufort Sea. A combination of carbon, nitrogen and sulfur stable isotopes and fatty acids were used to examine the influence of diet on MeHg concentrations in 476...

Information received in response to notices published in the Canada Gazette under sections 46 and 71 of the Canadian Environmental Protection Act 1999 (CEPA). These notices target certain substances under the Chemicals Management Plan. Supplemental Information To increase transparency and to...

As part of the research activities of the St. Lawrence Action Plan (SLAP) and in collaboration with Parks Canada, a 5-year monitoring program was initiated to assess the effect of metal and element contamination to clams in the Tadoussac area. The sites of concern included marinas near...

To increase transparency and to facilitate access to information on substances in Canadian commerce, the Government of Canada is publishing a compilation of the non-confidential information received in response to the Notice with respect to certain substances on the Revised In Commerce List,...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Population exposure to outdoor air pollutants indicator tracks the proportion of the Canadian population living in areas...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Canadian species index represents the average percent change in the sizes of Canadian vertebrate species' populations...

The Fish Contaminants Monitoring Program (FCMP) was initiated in 1976. The objective is to collect a variety of biological samples in freshwater environments for the purpose of determining ecosystem contaminant levels. Environment and Climate Change Canada (ECCC) collects biological samples from...

This project examined the use of parasites of slimy sculpin (Cottus cognatus) as indicators of water quality in the Athabasca River. Specimens of C. cognatus were sampled from four tributaries to assess patterns of helminth parasite community structure in this fish and to study the composition...

This study investigated the fate of rare earth elements (lanthanides) in in wastewater after being treated by various processes conducted at six different wastewater treatment plants throughout Canada. This research also focused specifically on the fate of medical gadolinium (Gd) which is used...

Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in Lake Superior, Nipigon Bay, and Black Bay are included in this dataset. The Lake Superior Survey methodology consists of four general steps; 1) delineating the coastal ecosystem into coastal units based on water...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Greenhouse gas concentrations indicator shows the trends in concentrations for 2 greenhouse gases: carbon dioxide (CO2)...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Global Trends in Conserved Areas indicator reports the amount and percentage of global terrestrial and marine area...

This study is focused on measuring lead in environmental matrices (surface water, sediment and tissues of recreational fish species) at locations known for high levels of recreational fishing activities (i.e. locations with high uses of lead in fishing sinkers and jigs) to determine the fate and...

As part of the research program on the aquatic ecotoxicology of nanomaterials, a study was carried out using the invertebrate Hydra vulgaris in order to determine the influence that the shape of nanoparticles (sphere, cube and prism) have on the toxic potential of silver nanoparticles. The...

NETCARE is a network comprised of researchers from ten Canadian universities (University of Toronto, University of British Columbia, Université du Québec à Montréal, University of Waterloo, Université du Québec à Rimouski, Laval University, Dalhousie University, University of Calgary, Université...
