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...

Neonicotinoids are the most widely used insecticides in the world and selective toxicity has resulted in the rapid and ubiquitous use of these compounds. Neonicotinoids are a class of neuro-active insecticides chemically similar to nicotine and are widely used in agriculture to protect crops from...

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...

This study aimed to better understand in situ cumulative effects of anthropogenic stressors on the health of St. Lawrence River (QC, Canada) yellow perch (Perca flavescens) populations using high-throughput transcriptomics and a multi-biological level approach. Fish were collected in the upstream...

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...

Multiple metabolic, immune and reproductive effects have been reported in fish residing in effluent-impacted sites. Natural stressors such as parasites also have been shown to impact the responses of organisms to chronic exposure to municipal effluent in the St. Lawrence River (Quebec, Canada)....

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 3 site locations (Peche Island, Grosse Ile, Turkey Creek) within the Detroit River Area of Concern. Halogenated Phenolic Compounds have emerged as...

The epiphytic cyanobacterium Gloeotrichia pisum forms spherical colonies embedded in a gelatinous matrix that is attached to submerged aquatic vegetation. In surveys of two fluvial lakes of the St. Lawrence River conducted in 2006–2007, growth conditions and diazotrophic ability in conjunction...

Increased productivity from sewage effluents can enhance species richness locally. Results from a study of Spottail shiners (Notropis hudsonius) in 1999 showed that prevalence and the mean number of myxozoan parasite species per host were higher downstream of the wastewater outflow from the...

Dataset contains laboratory-studied Fathead minnow (Pimephales promelas) survival when exposed to bitumen sediments from the oil sands region of northern Alberta, cut through the McMurray Formation (MF). These are the results of the toxicological exposures, when Fathead minnow embryos were...

This collection of data summarizes the companies and facilities reporting under the Fuels Information Regulations, No. 1. This dataset includes total fuel volumes, sulphur contents and masses, and companies reporting production and/or importation of liquid fuels originating from crude oils, coal...

This dataset contains the ambient dissolved concentrations of organophosphate esters (OPEs) and polybrominated diphenyl ethers (PBDEs) in North Atlantic Ocean (Greenland Sea) as well as a summary of the passive polyethylene samplers (PEs) deployed. Organophosphate esters (OPEs) have been found in...

Wild fish community data (species, abundance, diversity, length, weight) for 2013 and 2019 are now available for tributaries of the Athabasca River (rivers Steepbank, Ells, Firebag, High Hills, Dunkirk, Horse, Muskeg, Tar and Calumet) and 2017 data for rivers and creeks adjacent to Christina Lake...

This dataset contains the overall health and endocrine function of Brown bullhead (Ameriurus nebulosus) and Goldfish (Carassius auratus) from the Wheatley Harbour Area of Concern using a suite of physiological and biochemical endpoints. Supplemental Information Funding for this study was provided...

This dataset contains the growth and survival data for Fathead minnow (Pimephales promelas) exposed to sediment from twelve sites within the Hamilton Harbour Area of Concern, as well as reference sediment (a mixture of sediment from two reference sites within Lake Erie, Long Point Marsh and Long...

Categorization was required by the Canadian Environmental Protection Act, 1999 (CEPA 1999) and is a first step to finding out which of these chemical substances require further attention in the form of assessment, research and/or measures to control their use or release. This task was completed...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 4 site locations (Trenton, Deseronto, Belleville, Prince Edward Bay) within the Bay of Quinte Area of Concern. Halogenated Phenolic Compounds have...

As part of a three year study funded by Environment and Climate Change Canada and Natural Resources Canada (ecoENERGY Innovation Initiative, project UOSGQ963; http://www.nrcan.gc.ca/energy/funding/current-fundingprograms/eii/4985) data were gathered to assess and monitor water quality conditions...

Athabasca River (includes sites M2, M3, M4, M5, M6, M7 [2011-March 2018]) Water quality chemistry data for 17 sites in the lower Athabasca River (LAR), the Peace and Slave rivers, and their tributaries, including measurements of major ions, nutrients, metals (dissolved and total) and organics...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Trends in Canada's bird populations indicator reports population trends of Canada's native bird species from 1970 to...
