Biomedical or hospital waste: Waste generated by human or animal health care facilities, medical or veterinary research and testing establishments, health care teaching establishments, clinical testing or research laboratories and facilities involved in the production or testing of vaccines. Biogenic emissions: Biogenic emissions refer to emissions of volatile organic compounds from vegetation and emissions of nitrogen oxides from soil. It does not include aluminum or any other metals. Article: A manufactured item that does not release a substance, listed in Schedule 1 of the Canada Gazette notice, when it undergoes processing or other use.ī Base metal: Copper, lead, nickel or zinc.

Area sources: Small collective sources that are inventoried as a group, such as any small residential, governmental, institutional, commercial or industrial fuel combustion operations on-site solid waste disposal facilities and motor vehicles, aircraft, vessels or other transportation facilities as well as other miscellaneous sources, which are too numerous to inventory as point sources. However, there is a growing list of NPRI substances that have an alternate threshold ( ATH) and many of the substances that are being or will be added to the NPRI in future may require an ATH. Alternate threshold substances ( ATH): Reporting for the majority of substances currently listed on the NPRI is triggered when the substance is manufactured, processed or otherwise used in quantities equal to or greater than 10 tonnes. Alloys: Metal products containing two or more elements as a solid solution, intermetallic compounds and mixtures of metallic phases. If acidic drainage is left uncollected and untreated, the drainage could contaminate groundwater and local water courses, damaging the health of plants, wildlife, and fish.

Rainfall and snowmelt flush the metal-laden acidic solutions from the waste sites into the downstream environment. The produced acid can leach metals from surrounding rocks, causing drainage that has elevated levels of metals and dissolved salts. Acidic drainage: A naturally-occurring process caused when rock materials containing sulphur are exposed to both oxygen and water, and when insufficient acid-neutralizing minerals are present. A Abrasive blasting: The process of cleaning or texturing materials such as metals and ceramics with an abrasive material.
