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 year. The data are also available in a virtual globe format : https://open.canada.ca/data/en/dataset/d9be6bec-47e5-4835-8d01-d2875a8d67ff Please consult the following resources to enhance your analysis: - Guide on using and Interpreting NPRI Data: https://www.canada.ca/en/environment-climate-change/services/national-pollutant-release-inventory/using-interpreting-data.html - Access additional data from the NPRI, including datasets and mapping products: https://www.canada.ca/en/environment-climate-change/services/national-pollutant-release-inventory/tools-resources-data/exploredata.html

The Regional Air Quality Deterministic Prediction System FireWork (RAQDPS-FW) carries out physics and chemistry calculations, including emissions from active wildfires, to arrive at deterministic predictions of chemical species concentration of interest to air quality, such as fine particulate matter PM2.5 (2.5 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available at a horizontal resolution of 10 km. While the system encompasses more than 80 vertical levels, data is available only for the surface level. The products are presented as historical, annual or monthly, averages which highlight long-term trends in cumulative effects on the environment.

This dataset includes all significant new activity (SNAc) orders and notices published under the authority of the Canadian Environmental Protection Act, 1999 (CEPA). The SNAc provisions of CEPA may be applied to a substance or living organism when Environment and Climate Change Canada and Health Canada suspect that a significant new activity in relation to the substance or living organism may pose new or increased risks to the environment or to human health. Information is organized by substance and includes links to relevant Canada Gazette publications. Confidential accession numbers and masked names have been presented for confidential substances. Although great care has been taken to ensure the information herein accurately reflects the requirements prescribed in CEPA, you are advised that, should any inconsistencies be found, the legal documents, published in the Canada Gazette, will prevail. Please note that substances on the Domestic Substances List (DSL) may be presented with a flag next to the substance identification number in official Canada Gazette publications. These flags are included in a separate column in the dataset, and are as follows: S: The “S” flag indicates that the SNAc provisions of CEPA apply to the substance. S': The “S'” (S prime) flag indicates that the SNAc provisions of CEPA apply to a substance that was already listed on the DSL. P: The “P” flag indicates that the substance was assessed and added to the DSL on the basis that it met the Reduced Regulatory Requirement polymer criteria. T: The “T” flag indicates that the substance was manufactured or imported during the transitional period (January 1, 1987 to July 1, 1994). N: The “N” flag indicates that the substance was manufactured or imported after July 1, 1994.

This dataset includes all ministerial condition (MC) notices published under the authority of the Canadian Environmental Protection Act, 1999 (CEPA). The MC notice may be applied to a new substance or living organisms when Environment and Climate Change Canada and Health Canada suspect that a new substance may meet the criterial for toxic under CEPA. When Ministerial conditions are imposed, the notifier can manufacture or import the substance, subject to restrictions. The notifier and, if specified in the condition, the notifier’s customers are obliged to abide by these conditions and keep records as indicated. Substances subject to ministerial conditions are not eligible for addition to the Domestic Substances List. Therefore, any new notifier who wishes to manufacture or import the same substance must submit a New Substances Notification. This may result in similar conditions being imposed. Information is organized by substance and includes links to relevant Canada Gazette publications. Confidential accession numbers and masked names have been presented for confidential substances. Although great care has been taken to ensure the information herein accurately reflects the requirements prescribed in CEPA, you are advised that, should any inconsistencies be found, the legal documents, published in the Canada Gazette, will prevail.

The proposed study will contribute to the development of a comprehensive and long-term strategy to monitor wetland health in the oil sands region. After successful deployment of semipermeable membrane devices (SPMDs) in 2013, 2014, and 2015 to assess anthropogenic input of PAHs in shallow boreal wetlands (under the auspice of JOSM) work will continue with an emphasis on using passive sampling technologies. In addition to SPMDs, we propose to pilot sampling devices designed to target other oil sands-related contaminants. Specifically, we will target the use of diffusive gradients in thin films (DGTs) and polar organic chemical integrative samplers (POCIS) for mercury and naphthenic acids, respectively.

The Regional Deterministic Air Quality Analysis (RDAQA) is an objective analysis of surface pollutants which combines numerical forecasts from the Regional Air Quality Deterministic Prediction System (RAQDPS) and hourly observational data from monitoring surface networks over North America in order to produce a better description of the air quality at every hour. Chemical constituents include 03, SO2, and NO2 gases, as well as fine particulate matter PM2.5 (2.5 micrometers in diameter or less) and coarse particulate matter PM10 (10 micrometers in diameter or less). Geographical coverage is Canada and the United States. Data is available only for the surface level, at a horizontal resolution of 10 km. The products are presented as historical, annual or monthly, averages which highlight long-term trends in cumulative effects on the environment.

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 by September 2006, as required by the act. Using information from Canadian industry, academic research and other countries, Government of Canada scientists worked with partners in applying a set of rigorous tools to the 23,000 chemical substances on the Domestic Substances List (DSL). They were categorized to identify those that were: • Inherently toxic to humans or to the environment and that might be: o Persistent (take a very long time to break down), and/or o Bioaccumulative (collect in living organisms and end up in the food chain) • Substances to which people might have greatest potential for exposure. Through categorization, the Government of Canada identified approximately 4,000 of the 23,000 chemical substances on the DSL as meeting the criteria for further attention.

This study examined the effect of two dinonylnaphthalene sulfonic acids (NSAs) on freshwater organisms: calcium dinonylnaphthalene sulfonate (CaDNS), and dinonylnaphthalene disulfonic acid (DNDS). Chronic effects were characterized by exposing fertilized fathead minnow eggs to sediment-associated NSAs and measuring various developmental and growth endpoints for 21 days.
