Environment and Climate Change Canada

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...

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...

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...

This data collection contains precipitation concentration data of anthropogenic organic pollutants in precipitation (AOPP). Some of these AOPPs reported in this data collection are considered toxic substances (e.g. polychlorinated biphenyls, PCBs; polycyclic aromatic hydrocarbons, PAHs; some...

Information received in response to the notice with respect to certain aromatic amines and aromatic azo and benzidine-based substances (2011). 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 Canadian Ozonesonde Network measures vertical profiles of ozone from ground level up to 36 km altitude across Canada. The objectives of the network are to provide long-term stratospheric and tropospheric ozone data for periodic assessment of the state of the ozone layer, to validate satellite...

The CanESM2 large ensembles are 50-member perturbed initial condition ensembles from 1950 to 2020, with all historical forcings (historical), solar and volcanic forcings only (historicalNat), anthropogenic aerosols only (historicalMisc, p4), and ozone only (historicalMisc, p6). The model,...

At all locations the TGM measurements were made using automatic Tekran ® 2537 mercury vapour analyzers (described in detail in Poissant, 1997). The air is typically sampled at flow rates between 1.0 and 1.5 L/min (depending on location) and is passed through a Teflon filter (47 mm diameter; 0.45...

Information received in response to the data gathering initiative on certain selenium-containing substances (2013). 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 received...

Information received in response to the data gathering initiative on certain organic flame retardants (2013) 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 received in...

This notice applies to owners of dental facilities that perform activities in relation to dental amalgam or elemental mercury. This notice has been in effect since May 8, 2010, for owners of dental facilities. Although the initial facilities subject have completed their obligations, this notice...

Ambient concentrations of speciated mercury (Hg) have been measured at many locations across Canada. Mercury in the atmosphere is measured in three operationally-defined forms - gaseous elemental mercury (GEM), reactive gaseous mercury (RGM), and particulate-bound mercury (PBM). Under most...

This notice applies to owners of facilities that manufacture or use greater than 100 kg of bisphenol A per year (alone or in a mixture), release effluents containing bisphenol A, and are involved in the activities specified in the notice. This notice has been in effect since April 14, 2012, for...

The Climate Research Division's climate modelling program provides climate model output for the climate science and climate change research community, nationally and internationally. This dataset includes global Earth System model output (from several generations of models), regional climate...

Measurements of gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM) and particulate bound mercury on PM2.5 (referred to as PBM2.5) were collected by Environment and Climate Change Canada from August to September 2013 at the Wood Buffalo Environmental Association (WBEA) Air Monitoring...

Information received in response to the data gathering initiative on certain phthalate substances (2013). 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 received in response...

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