"National Ambient Air Quality Objectives (NAAQO) are benchmark levels of protection for people and the environment in Canada. The criteria for their development and use must be based on scientifically defensible evidence while incorporating a margin of protection that reflects three factors: variability in the levels of exposure and their associated effects; uncertainty in the analysis, and the values of Canadian society. This document explains how scientific information is obtained, evaluated, and published in support of NAAQOs"--Introd.
