In an effort to increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is publishing a summary of the information received in response to the Notice to provide information for the risk management of certain coal tars and their...

The d4PDF-WaveHs dataset represents the first single model initial-condition large ensemble (SMILE, 100-member) of historical significant ocean wave height (Hs) at a global scale. It was produced using an advanced statistical model with predictors derived from Japan's database for policy...

This dataset contains 21 statistics (including extreme indices) of wind and waves calculated from hourly reanalysis data of historical surface winds and ocean surface waves for the Davis Strait Baffin Bay waters for the period 1979-2018 (each statistic has an annual and 12 monthly values). These...

This data set contains concentrations of organophosphate flame retardants in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTP's) and Landfills across Canada. Supplemental Information...

Ambient concentrations of speciated mercury (Hg) have been measured at many locations across Canada. Mercury in the atmosphere is measured in three operationally-defined forms - gaseous elemental mercury (GEM), reactive gaseous mercury (RGM), and particulate-bound mercury (PBM). Under most...

Metals in Mallards (pooled 2013 collections) Adult male mallards were collected in 2013 in the area surrounding five Alberta communities south of the Athabasca oil sands industrial region (Mayerthorpe, Barrhead, Lac La Biche, St. Paul and Vermilion) and from two communities north of the...

Assessing polycyclic aromatic hydrocarbon and naphthenic acid concentrations in soils collected in 2012 – Field and Laboratory Assessment of Contaminants The concentrations of polycyclic aromatic hydrocarbons (PAHs) and naphthenic acids (NAs) were measured in soil samples collected in 2012....

The Greenhouse Gas Reporting Program (GHGRP) collects information on greenhouse gas (GHG) emissions annually from facilities across Canada. It is a mandatory program for those who meet the requirements. Facilities that emit 10 kilotonnes or more of GHGs, in carbon dioxide (CO2) equivalent (eq.)...

Plant species richness, composition, and soil chemistry parameters were assessed in wetlands and uplands in the oil sands region of northern Alberta. The concentrations of metals and polycyclic aromatic hydrocarbons (PAHs) were measured in soil and plant samples collected from 2012-2014, and...

The Great Lakes Sediment Database (also known as the National Water Research Institute (NWRI) Sediment Archive) is an archive of data on the sediments of the Great Lakes, their connecting channels, and the St. Lawrence River which was collected by NWRI and in cooperation with other agencies...

This data set contains concentrations of bisphenols 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. Supplemental Information Supporting Projects:...

This data set contains concentrations of nonylphenols and its ethoxylates in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTP's) and Landfills across Canada. Supplemental Information...

This data set contains concentrations of halogenated flame retardants in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTP's) and Landfills across Canada. Supplemental Information Supporting...

This data set contains concentrations of triclosan in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTP's) and Landfills across Canada. Supplemental Information Supporting Projects:...

This data set contains concentrations of tetrabromobisphenol A in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTP's) and Landfills across Canada. Supplemental Information Supporting...

The specific composition, biomass, vertical distribution and metal content of submerged and emergent aquatic plants in the St. Lawrence were evaluated. The riparian vegetation community of the St. Lawrence is characterized by the presence of extensive wetlands in the floodplain, a border of...

Over the past five decades, many lakes, ponds, and wetlands (generically termed basins) of the Peace Sector of the Peace-Athabasca Delta (PAD), a significant component of the Wood Buffalo National Park (WBNP), have experienced drying trends in-between infrequent flooding generated by major spring...

Aerial surveys were performed in the Rasmussen Lowlands, Nunavut, to determine the numbers and distribution of Greater White-fronted Geese and other waterfowl species. Surveys were carried out in the Lowlands from 20-24 June 1994 and 20-25 June 1995. The survey procedure included flying straight...

This study examined the toxicity of aged oil sands tailings waste, and it's affect on eight species of freshwater aquatic organisms: Pimephales promelas (fathead minnow), Oryzias latipes (Japanese medaka), Hyalella azteca, Daphnia magna, Vibrio fischeri, Lampsilis cardium, Ceriodaphnia dubia, and...

Global climate change has altered the timing of seasonal events for a diverse range of biota. Within and among species, however, phenological responses to climate change vary substantially. To better understand factors driving this variability in organismal responses, we evaluated changes in...
