Polluants

Nettoyage manuel de la rivière à partir d'une yole.Les polluants sont des substances qui sont directement ou indirectement nocives pour la santé humaine ou l'environnement. Les risques qu'ils comportent dépendent de facteurs comme leurs propriétés physiques et chimiques, leur toxicité, les quantités qui sont rejetées et l'endroit où ils retombent, et la façon dont ils se décomposent.

Les substances les plus toxiques sont ciblées en vue de leur quasi-élimination par la Loi canadienne sur la protection de l'environnement. Environnement Canada utilise des inventaires pour suivre le rejet des gaz à effet de serre, des principaux contaminants atmosphériques et d'autres polluants afin d'appuyer cette loi et d'autres activités de réduction.

La présente section renseigne sur les polluants et leurs incidences.
