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.

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...

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); Particulate...

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...

Regionally representative data from Canada and the U.S. collected using wet-only precipitation collectors including Canadian federal and provincial networks (past and present) and U.S. historical networks (for data not available elsewhere). Data product types include major ions (also known as...

The Great Lakes Basin (GLB) Monitoring and Surveillance program under the Chemicals Management Plan (CMP) of Environment and Climate Change Canada (ECCC) has been operating since 1990 as a result of provisions called for in the Great Lakes Water Quality Agreement (GLWQA) between Canada and the...
