The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The phosphorus loading to lake Erie indicator reports on the total phosphorus loads flowing directly into Lake Erie or from...

Examining the short- and long-term toxicity effects (survival, behaviour and egg production) of Bisphenol A (BPA) and its replacement products (BPS, BPF, BPAF) on the embryo, juvenile and adult life stages of the Ramshorn snail (Planorbella pilsbryi) in 96-hour/7-day/13-day...

The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In partnership with the provinces, territories and other agencies, WSC operates over 2800 active hydrometric...

This study aimed to address the toxicological effects the type-2 diabetes drug, metformin has on wild fathead minnows (Pimephales promelas). Fathead minnow embryos and adults were exposed to metformin via in-lake mesocosm and their survival, development and growth was assessed. Exposures were...

Zooplankton and phytoplankton were collected during the 56-day metformin in-lake mesocosm exposure conducted Lake 114 at the International Institute for Sustainable Development-Experimental Lakes Area (IILSD-ELA) in northern Ontario, Canada. Samples were collected three times throughout the...

This study will determine the toxic effect the pharmaceutical metformin has on an aquatic environment. Chronic exposures were conducted at Lake 114 located at the International Institute for Sustainable Development-Experimental Lakes Area (IILSD-ELA) in Ontario, Canada. Three concentrations of...

The daily water temperature (°C) dataset is reconstructed using the air2stream model (Toffolon and Piccolroaz 2015) with i) air temperature from ~10 km resolution 1980-2018 Regional Deterministic Reforecast System, version 2.1 (Gasset et al. 2021) and ii) streamflow data from the Water Survey of...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Each file contains facility-reported data listed by facility and substance for a given year. Data are presented in a table and can...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Each file contains annual total releases for the past five years by media (air, water or land), broken-down by province, industry or...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Each file contains data from 1993 to the latest reporting year. These CSV format datasets are in normalized or ‘list’ format and are...

Long-term freshwater quality monitoring data for Rainy River / Lake of the Woods Watershed 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 (ECCC)...

As part of the research program on the aquatic ecotoxicology of nanomaterials, a study was carried out using the invertebrate Hydra vulgaris in order to determine the influence that the shape of nanoparticles (sphere, cube and prism) have on the toxic potential of silver nanoparticles. The...

The toxic effects of a representative mixture (mining activities) of rare earth elements are studied in the hydra, an organism particularly sensitive to these elements. All data are a part subject of a publication containing method details, full QA/QC, interpretation and conclusions. Citation:...

Permafrost loss is pervasive across northern circumpolar regions. The loss of frozen ground has profound impacts on water resources at varying spatial and temporal scales via changes to predominant hydrological processes, runoff pathways and entrainment rates of solutes and sediments. Consensus...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Huron and St. Marys River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into an overall...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. This file is a geodatabase (GDB) that shows the locations of all facilities that reported to the NPRI in the current reporting...

National Water Monitoring Program for Pesticides (NWMPP) water quality data are presented for a network of freshwater sites across Canada. A two-year pilot program is being conducted in partnership between Health Canada (HC), Environment and Climate Change Canada (ECCC), and Agriculture 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...

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,...

Water level and discharge data are available from Water Survey of Canada’s Hydrometric Network. The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In...
