This data set contains concentrations of pharmaceuticals and personal care products (PPCPs) and hormones in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada....

This data set contains concentrations of brominated flame retardants (BFRs) in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada. Scientific Publications:...

The Canadian Air and Precipitation Monitoring Network (CAPMoN), operated by Environment and Climate Change Canada (ECCC), is designed to study the regional patterns and trends of atmospheric pollutants such as acid rain, smog, particulate matter and mercury, in both air and precipitation. The...

Monitoring of sea ice dynamics is of vital importance to our overall understanding of how the Arctic cryosphere is responding to changes in the Earth's climate. With the recent launch of the RADARSAT Constellation Mission (RCM) in 2019 and the continuing operation of the Sentinel-1 (S1) fleet,...

Humidex (Masterton and Richardson 1979) is an index developed by the Meteorological Service of Canada to describe how hot and humid the weather feels to the average person. In Canada, it is recommended that outdoor activities be moderated when the humidex exceeds 30, and that all unnecessary...

Weekly precipitation quantity has been measured at both at the primary meteorological site as well as at five other sites within the watershed. Daily precipitation quantity has been measured at the primary meteorological site until 2017. Weekly chemistry analysis of H+, major ions, nutrients and...

This study set out to provide an up-to-date portrait of the per- and polyfluoroalkyl substances (PFAS) contamination status in a freshwater food web from the St. Lawrence River (QC, Canada). Water, sediments, aquatic vegetation, invertebrates, and some fish species were targeted for analysis. All...

Ammonia (NH3) data were collected at regionally representative Canadian Air and Precipitation Monitoring Network (CAPMoN) sites. Radiello brand passive samplers were deployed at 2 or 5 m above the ground for two week periods and analyzed by the National Atmospheric Deposition Program (NADP)...

We investigated the stable isotope hydrology of Sable Island, NS, Canada over a four year period from September, 2017 until August, 2021. The δ2H and δ18O values of integrated monthly precipitation were weakly seasonal and ranged from -66 to -17 per mil and from -9.7 to -3.1 per mil,...

A high-resolution digital elevation model (DEM) is key to assessing habitat conditions, surface water connectivity, developing hydraulic models, and environmental change in the Peace-Athabasca Delta (PAD), Northern Alberta. Note that in this instance, DEM is a representation of the ground surface...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Land-based greenhouse gas emissions and removals indicator tracks exchanges of greenhouse gas (GHG) emissions and...

A collection of citation information for scientific and technical articles authored / co-authored by Environment Canada researchers.

This is a database of modeled two-year (2016-2017) average dry deposition velocities (Vd) for 45 gaseous species and three particle size ranges at a 15 km by 15 km horizontal resolution across North America. The dry deposition schemes of Zhang et al. (2003) and Wu et al. (2021) were used for...

Meteorological Observations describe datasets that contain information about weather and climate conditions as available on the City-Pages of the Environment Canada WeatherOffice.gc.ca web site. These pages contain information about current weather conditions and past climate including...

High-resolution ground terrain elevational data are key to assessing habitat conditions, surface water connectivity and environmental change in the Peace-Athabasca Delta (PAD), Northern Alberta. LiDAR (Light Detection and Ranging) is a remote sensing technology that has recently become more...

The World Meteorological Organization (WMO) Solid Precipitation Inter-Comparison Experiment (SPICE) officially began in the (Northern Hemisphere) Fall of 2012 with the objective of characterizing and providing guidance on the performance of automated systems for the in situ measurement of solid...

Drought projections on seasonal to annual time scales are presented for Canada over the twenty-first century, based on the Standardized Precipitation Evapotranspiration Index (SPEI). Results make use of bias-corrected temperature and precipitation projections from 29 global climate models...

The Environmental Damages Fund (EDF), created by the Government of Canada in 1995, follows the Polluter Pays Principle to ensure that those who cause damage to the environment take responsibility for their actions. Prosecutors and judges can recommend that financial penalties (fines, awards...

This study examined the effect of two dinonylnaphthalene sulfonic acids (NSAs) on freshwater organisms: calcium dinonylnaphthalene sulfonate (CaDNS), and dinonylnaphthalene disulfonic acid (DNDS). Chronic effects were characterized by exposing fertilized fathead minnow eggs to sediment-associated...

The datasets and maps are associated with a research study. Annual total (dry + wet) deposition fluxes of nitrogen (nitric acid, nitrate and ammonium) and sulfur (sulfur dioxide and sulfate) were determined at 15 Canadian Air and Precipitation Monitoring Network (CAPMoN) sites from 2000 to 2018....
