Tire wear particles end up on roads where they may run off into nearby rivers and lakes by rain and snowmelt. This study examined how toxic these tire particles are to eggs and the newly hatched larvae of the fathead minnow (Pimephales promelas). Tire particles were finely ground up and were...

This study aimed to identify chemical components that could distinguish chemical mixtures in oil sands process-affected water (OSPW) from natural groundwater sources. Oil sands process-affected samples were collected from two different oil sands development tailing ponds, and natural groundwater...

This dataset displays the geographic areas within which critical habitat (CH) for terrestrial species at risk, listed on Schedule 1 of the federal Species at Risk Act (SARA), occurs in Canada. Note that this includes only terrestrial species and species for which Environment and Climate Change...

This study examined the presence and effect of micro and nanoplastics in an urban environment on the freshwater mussel, Elliptio complanata. Mussels were collected from a pristine lake located in the Laurentians region in Quebec, Canada, and placed in three locations in the St. Lawrence River...

The specific composition, biomass, vertical distribution and metal content of submerged and emergent aquatic plants in the St. Lawrence were evaluated. The riparian vegetation community of the St. Lawrence is characterized by the presence of extensive wetlands in the floodplain, a border of...

Temporal changes (1970–2016) in St. Lawrence River wetlands were assessed between Cornwall and Québec to assess wetland response to cumulative anthropogenic pressures in the watershed. Emergent wetlands area and biomass of submerged aquatic vegetation (SAV) were contrasted among five regions...

Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. Stormwater ponds have also been designed to provide multiple other benefits; including protection of downstream waters, sediment and habitat (land/aquatic) quality,...

This dataset contains the growth and survival data for Fathead minnow (Pimephales promelas) exposed to sediment from eleven sites within the St. Marys Area of Concern, as well as reference sediment (a mixture of sediment from two reference sites within Lake Erie, Long Point Marsh and Long Point...

Water quality monitoring data collected in priority tributaries to provide nutrient concentration data to estimate nutrient loads to the waters of the Great Lakes. Data is collected to advance the science to understand and address the complex problem of recurrent toxic and nuisance algae in the...

As indicated in the Notice with respect to certain quaternary ammonium compounds in Canadian commerce — Phase 1 (the Notice), and in accordance with section 49 of the Canadian Environmental Protection Act, 1999 (CEPA), the Government of Canada is providing a summary of the information received in...

The specific composition, biomass, vertical distribution and metal content of submerged and emergent aquatic plants in the St. Lawrence were evaluated. The riparian vegetation community of the St. Lawrence is characterized by the presence of extensive wetlands in the floodplain, a border of...

This study examined the toxicity of aged oil sands tailings waste, and it's affect on eight species of freshwater aquatic organisms: Pimephales promelas (fathead minnow), Oryzias latipes (Japanese medaka), Hyalella azteca, Daphnia magna, Vibrio fischeri, Lampsilis cardium, Ceriodaphnia dubia, and...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. Canada's conserved areas indicators report the amount and proportion of Canada's terrestrial (land and freshwater) and marine...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. These indicators track human-related emissions to air of 3 substances that are defined as toxic under the Canadian...

The purpose of this study was to assess the release and characterization of forms of silver nanoparticles (AgNPs) in urban effluents across Canada. Samples were collected from various wastewater treatment plants and were measured and analyzed using the single particle ICP-MS technique...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Water quantity in Canadian rivers indicator provides a national summary of the annual water quantity status in rivers...

The Air Pollutant Emission Inventory (APEI) is an annual report of air pollutant emissions across Canada published by Environment and Climate Change Canada. The report details the release of air pollutants from all known of sources since 1990. The APEI serves many purposes, including:...

Water quality and ecosystem health data collected using a risk-based monitoring approach to support the Great Lakes Water Quality Agreement are included in this dataset. By conducting regular, systematic measurements of the physical, chemical and biological conditions of the Great Lakes...

"The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Air pollutant emissions indicators track emissions from human activities of 6 key air pollutants: sulphur oxides,...

The Canadian Protected and Conserved Areas Database (CPCAD) is the authoritative source of data on protected and conserved areas in Canada. The database consists of the most up-to-date spatial and attribute data on marine and terrestrial protected areas in all governance categories recognized by...
