Description

Alberta Environment and Parks has finalized a new Alberta Ambient Air Quality Guideline for total reduced sulphur compounds, to be used for odour management. Alberta Environment and Parks recognizes that further guidance is needed to reduce the operational burden related to reporting values above the Alberta Ambient Air Quality Guideline, while still achieving the desired outcome of odour management. The Air Monitoring Directive requires immediate reporting of exceedances of ambient air quality objectives and guidelines. This protocol is to outline electronic reporting procedures for ambient TRS monitoring for values above the Alberta Ambient Air Quality Guideline for both industrial operations and Alberta airsheds.

Description

Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for acrolein. Acrolein is a reactive unsaturated aldehyde that exists as a highly volatile clear or yellow liquid. The largest commercial use of acrolein is as a biocide for aquatic environments, specifically for eradicating floating aquatic weeds or bacteria in produced water. In Alberta, acrolein has also been used to scavenge hydrogen sulphide from produced fluid in petroleum operations.

Description

Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for nitrogen dioxide. Nitrogen dioxide is an irritating gas with an acrid, pungent odour. It is corrosive, highly oxidizing and non-combustible. It can be released directly to the atmosphere but is often produced by the conversion of nitric oxide released from combustion processes. In the presence of sunlight, nitrogen dioxide can lead to the formation of ozone, nitric acid and nitrate-containing respirable particles.

Description

Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for formaldehyde. Formaldehyde is a colorless, flammable gas with a pungent, suffocating odour. It is considered one of the most widely used industrial and research chemicals, used primarily in the manufacturing of resins, fertilizers and other compounds.

Description

Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for isopropanol. Isopropanol is a colourless, clear, volatile liquid under standard conditions. It can react with air or oxygen to form unstable peroxides. Isopropanol has widespread use as a solvent and as a component of many industrial, commercial and consumer products. Isopropanol is also a naturally occurring metabolic product in a variety of microorganisms and plants; as such, it occurs naturally in a wide variety of foods.

Description

Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for 2-Ethylhexanol . 2-Ethylhexanol is a clear, colourless liquid with an odour described as sweet, floral, intense, and unpleasant. It occurs naturally in food and is also added as flavouring to foods. This compound is used predominately in the production of plasticizers for PVC resins, hexyl esters, and arylates. It is also used in textiles and as a solvent and wetting agent.

Description

Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for reduced sulphur compounds (RSC). Reduced sulphur compounds are a complex family of substances. They are defined by the presence of sulphur in a reduced state and are generally characterized by strong odours at relatively low concentrations. One member of the family—hydrogen sulphide (H2S)—is known to have highly toxic properties, and can cause negative health effects at low concentrations. Natural sources of RSC in air include volcanoes and sulphur springs, oceans and estuaries, and exposed faces of sulphur-containing oil and coal deposits. The primary anthropogenic sources include oil and gas processing facilities, Kraft pulp mills, chemical manufacturing plants, and livestock operations.

Description

Ambient air quality objectives are established as part of the Alberta air quality management system. The purpose of this assessment report was to provide a review of scientific and technical information to assist in evaluating the basis and background for an ambient air quality objective for toluene. Toluene is a clear, colourless, volatile and flammable liquid under standard conditions. It is a naturally occurring component of crude oil and petroleum. Toluene is also formed during the combustion of organic materials; thus forest, grass and other biomass fires will release toluene to the atmosphere. The manufacturing of toluene occurs primarily via isolation from petroleum mixtures by the distillation of reformed or pyrolyzed petroleum and coal-tar oil. Toluene is widely used as a solvent in paints, varnishes, pesticide formulations, printing inks, dyes, adhesives, sealants, cleaning agents, nail polish, and for chemical extractions. Toluene also is used as a feedstock or starting...
