Atmospheric concentrations and deposition rates of particulate elements are important indicators for determining the potential impacts of the oil sands industries on the local environment. The datasets consist of measured ambient air concentrations (in PM2.5 and PM2.5-10) and estimated deposition...

Precipitation measurements in the Environment and Climate Change Canada (ECCC) surface network are a necessary component for monitoring weather and climate and are required for flood and water resource forecasting, numerical weather prediction and many other applications that impact the health...

As part of research projects in Environment and Climate Change Canada, historical physical limnology observations have been collected in Canadian Lakes since 1968. These observations include one or more concurrent measurements of water temperature profiles, directional velocities (east-west and...

This dataset contains annual algal bloom indices (duration, extent, intensity, severity) summary statistics (maximum, mean) over the June through October monitoring period for Lake Erie. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's) MEdium...

The Great Lakes Basin Integrated Nutrient Dataset compiles and standardizes phosphorus, nitrogen, and suspended solids data collected between the 2000-2019 water years from multiple Canadian and American sources around the Great Lakes. Ultimately, the goal is to enable regional nutrient data...

Sediment profile imagery (SPI) (also known as REMOTS (Rhoads and Germano, 1982)) facilitates the assessment of the biophysical processes that occur in the benthic environment through the acquisition and analysis of high resolution images of vertical sections and surfaces of the seafloor. The SPI...

This data collection contains particulate metals data measured at sites in Canada. For additional data on pollutants in air, also see the data collection of Anthropogenic Organic Pollutants in Air. For additional data on metals, also see the data collection of Metals in Precipitation.

Total gaseous mercury (TGM) data are currently collected by Environment and Climate Change Canada at two Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations (AMS). Preliminary, hourly averaged TGM data from the oil sands region are available for: WBEA AMS 6 - Patricia McInnes,...

This notice applied to owners of textile mills that manufactured textile using wet processing, used nonylphenol and its ethoxylates, and discharged their effluents, with a daily flow greater than 30 m3, to an off-site wastewater treatment facility. This notice was in effect from December 4, 2004...

The Combined Atmospheric Gases and Particles data sets were collected at regionally representative sites from ground-based monitoring networks in Canada and the USA. The data are from Canadian federal and provincial networks (past and present) and U.S. historical networks (these data are not...

Trace gas data sets measured by Canadian and U.S. ground-based monitoring networks from 1982 to the present including non-methane hydrocarbons (NMHC), ozone (O3) and total gaseous mercury (TGM). Included are Canadian federal and provincial networks (past and present) and U.S. historical networks...

This notice applied to owners of wastewater systems that, as specified in the notice, released effluent to surface water and where the concentration of total residual chlorine in the effluent was greater than 0.02 mg/L. This notice was in effect from December 4, 2004, to June 15, 2010. It is now...

Environment and Climate Change Canada provides Spills Technology Databases including Physicochemical Properties of Petroleum Products. This database contains information on the properties and composition of various types of oils and petroleum products.

This data collection contains air concentration data (in both gas and particle phases) of anthropogenic organic pollutants in air (AOPA). Some of the AOPAs in air reported in this data collection, are considered toxic substances (e.g. polychlorinated biphenyls, PCBs; polycyclic aromatic...

This notice applies to owners of facilities that manufacture or use greater than 100 kg of siloxane D4 per year (alone or in a mixture), release effluents containing siloxane D4, and are involved in the activities specified in the notice. This notice has been in effect since June 2, 2012, for...

The purpose of Bird Conservation Regions strategies is to summarize the important issues and to recommend the actions required to conserve populations of birds in Canada. The Bird Conservation Regions (BCR) used as the basis for our planning units are based on the Commission for Environmental...

Particle data from Canadian and U.S. ground-based monitoring networks from 1982 forward include the following: Aerosol Optical Depth (AOD); Aerosol Size Distribution; Aerosol Number; Aerosol Chemical Composition; Particulate Matter Mass; Particulate Matter <= 2.5 microns (PM2.5);...

Information received in response to the data gathering initiative on certain substituted diphenylamine substances (2012). To increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is providing the summary of the information...

Long-term freshwater quality monitoring data for over 10 sites in the Pacific Coastal Basin 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...

The Canadian Brewer Spectrophotometer Network (CBSN) monitors the total thickness of the ozone layer (known as total column ozone) and ultraviolet (UV) radiation at selected monitoring locations across Canada. The objectives of the network are to provide long-term stratospheric ozone data for...
