Water temperature data were collected by Environment and Climate Change Canada at selected locations in Lake Winnipeg.Thermograph moorings were deployed in the north basin at station 505 and 506, in the south basin at station 500, in the Lake Winnipeg Narrows at station 502, northwest of Berens...

Fathead minnow (Pimephales promelas) embryos and larvae are frequently used in toxicology, including short-term embryo-only tests which often use small volumes of test solution. The effect that such conditions may have on Fathead minnow development has yet to be explicitly described. Here we...

Recent and historical deposition of mercury (Hg) are examined over a broad geographic area from southwestern Northwest Territories to Labrador and from the U.S. Northeast to northern Ellesmere Island using dated sediment cores from 50 lakes (18 in midlatitudes (41-50 degrees North), 14 subarctic...

The bioaccumulation of a broad range of pharmaceuticals and personal care product chemicals (PPCPs) was studied in Cootes Paradise Marsh (CPM), an urban wetland that receives tertiary treated municipal waste waters as well as urban storm runoff. PPCPs were measured in caged and wild goldfish, as...

This notice applied to owners of facilities that manufactured synthetic rubber using acrylonitrile which resulted in releases of acrylonitrile to the environment. This notice was in effect from May 24, 2003, to May 31, 2007, for facilities involved in the manufacture of synthetic rubber. It is...

Sidney Island Shorebird Surveys transects area feature.

Survey points is a point feature class containing transects and observations completed in 2011.

Restrictions in the utilization of polybrominated diphenyl ether (PBDE) mixtures have led to the increased usage of alternative flame retardant additives in a wide range of commercial applications. The present study examined the occurrence of established and emerging flame retardants (EFRs) in...

Neonicotinoids are the most widely used insecticides in the world. They are preferentially toxic to insects while displaying a low toxicity toward vertebrates, and this selective toxicity has resulted in the rapid and ubiquitous use of these compounds. However, neonicotinoids have been detected...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for Brown bullhead (Ameiurus nebulosus) and Yellow Perch (Perca flavescens) collected from three site locations (Queenston, Point Abino, and Black Creek) within the Niagara River Area of Concern for 2004 and 2008....

Freshwater mussels contribute important ecological functions to aquatic systems. The water filtered by mussel assemblages can improve water quality, and the mixing of sediments by burrowing mussels can improve oxygen content and release nutrients. However, nearly 70 percent of North American...

The study examines the parasite communities in Athabasca River Trout-perch (Percopsis omiscomaycus) at five sites along the main stem of the Athabasca River to explore whether any observed changes in parasite abundance or community structure might correlate with small-scale variations in water...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 3 site locations (Frenchman's Bay, Tommy Thompson, and Toronto Island) within the Toronto and Region Area of Concern. Halogenated Phenolic Compounds...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 2 site locations (Wheatley Harbour, and Hillman Marsh) within the Wheatley Harbour Area of Concern. Halogenated Phenolic Compounds have emerged as an...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for Brown bullhead (Ameiurus nebulosus) collected from three site locations (Frenchman's Bay, Toronto Island and Tommy Thompson) within the Toronto and Region Area of Concern for 2003 and 2006. Supplemental...

The Richelieu River, Quebec, is a highly-regulated waterway subject to numerous anthropogenic influences from municipal effluents and agricultural activities. Parasite communities in 234 spottail shiners (Notropis hudsonius) were examined from 4 localities in late spring 2003 and 2004. Parasite...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for White Sucker (Catostomus commersonii) collected from three site locations (Kaministiquia river, Kaministiquia river downstream and Little Gravel river used as a reference site) within the Thunder Bay Area of...

In this study, seven non‐specific biomarkers were compared in Spottail Shiners (Notropis hudsonius Clinton) from localities receiving urban and industrial effluents and relatively clean localities in the St Lawrence River, Canada. Pigmented macrophages are involved in a variety of functions...
