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...

Stream sampling was conducted in the Whitemans Creek watershed in February 2012 to assess water quality during winter baseflow conditions. A total of 30 stream sites were sampled where streams in the watershed intersected roadways. In addition to conventional water quality parameters (e.g.,...

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...

This project examined the effects of pesticides and agricultural practices on parasites of juvenile leopard frogs, Lithobates pipiens (formerly known as Rana pipiens) in southwestern Quebec, Canada. Nine wetlands and two reference sites were sampled in 2004 and 2005, all of which were in various...

As part of a study to characterize the habitat of Canada’s only known population of Hine’s emerald dragonfly (HED), a species listed as endangered since 2011, groundwater was collected and analyzed from the eastern Minesing Wetlands near Barrie, Ontario. The water quality analyses included...

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...

Since 2009, the Watershed Hydrology and Ecosystems Research Division of Environment and Climate Change Canada (ECCC) has coordinated spring time multi point ice thickness and composition surveys at up to 15 lake sites in the Northern Hemisphere. Data collected includes on ice snow depth, total...

Information received in response to notices published in the Canada Gazette under sections 46 and 71 of the Canadian Environmental Protection Act 1999 (CEPA). These notices target certain substances under the Chemicals Management Plan. Supplemental Information To increase transparency and to...

As part of the research activities of the St. Lawrence Action Plan (SLAP) and in collaboration with Parks Canada, a 5-year monitoring program was initiated to assess the effect of metal and element contamination to clams in the Tadoussac area. The sites of concern included marinas near...

To increase transparency and to facilitate access to information on substances in Canadian commerce, the Government of Canada is publishing a compilation of the non-confidential information received in response to the Notice with respect to certain substances on the Revised In Commerce List,...

The Fish Contaminants Monitoring Program (FCMP) was initiated in 1976. The objective is to collect a variety of biological samples in freshwater environments for the purpose of determining ecosystem contaminant levels. Environment and Climate Change Canada (ECCC) collects biological samples from...

This project examined the use of parasites of slimy sculpin (Cottus cognatus) as indicators of water quality in the Athabasca River. Specimens of C. cognatus were sampled from four tributaries to assess patterns of helminth parasite community structure in this fish and to study the composition...
