The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Each file contains facility-reported data listed by facility and substance for a given year. Data are presented in a table and can...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Each file contains annual total releases for the past five years by media (air, water or land), broken-down by province, industry or...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Each file contains data from 1993 to the latest reporting year. These CSV format datasets are in normalized or ‘list’ format and are...

Long-term freshwater quality monitoring data for Rainy River / Lake of the Woods Watershed for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC)...

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...

Numerous actions have been undertaken by farmers to attenuate the impact of agricultural activities on aquatic ecosystems. The identification of biomarkers that respond quickly to water quality improvement could facilitate the assessment of adopted alternative practices and help maintain...

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...

Substituted phenylamines (SPAs) are incorporated into a variety of consumer products (e.g., polymers, lubricants) in order to increase the lifespan of the products by acting as a primary antioxidant. Based on their physicochemical properties, if SPAs were to enter the aquatic environment, they...
