Pollutant Trend Report by Station

Description

All facilities that meet National Pollutant Release Inventory (NPRI) reporting requirements must report releases, disposals and transfers of substances to the NPRI. Facilities must also report information on pollution prevention activities and other information such as location, industry classification and the number of employees. For each facility and substance, data users can find out where and to what media (air, water or land) the substance was released. The information also includes how and where the substance was disposed of, treated or recycled. Substance reports submitted to NPRI by some facilities are separated into "Excluded Criteria Air Contaminants" and "Criteria Contaminants."

Excluded Criteria Air contaminants include things such as: trimethylbenzene, acenapthene, ammonia, arsenic, benzo(a), benzo(a)pyrene, benzo (b), benzo (g,h,i), cadmium, chronium, cobalt, copper, etc.

Criteria contaminants include things such as: sulphur dioxide, carbon monoxide, nitrogen oxides, PM- Total Particulate Matter, Volatile Organic Compounds (VOC's), PM10- Particulate Matter, and PM 2.5- Particulate Matter.

Usage Considerations

The Air Quality Index (AQI ) is a way of measuring the cleanliness of outdoor air, also known as ambient air. Alberta Environment measures the concentrations of five major air pollutants –carbon monoxide, fine particulate matter, nitrogen dioxide, ozone and sulphur dioxide—and averages those readings to an AQI number every hour. The higher the AQI number, the greater the level of pollution.

NB: Data was collected by the Alberta Environmental Monitoring, Evaluation and Reporting Agency (AEMERA) until June 30, 2016, at which point AEMERA was dissolved and the Environmental Monitoring and Science Division of Alberta Environment and Parks was created.
