Document Summary
Alberta regulator sets heavy oil odour rules. Pm2. 5 pollution levels (fine particulate) in delhi, india in october 2016 >700 uq/m3 classified as hazardous, 29x higher than who standards. Absorptive capacity: ability of the environment to absorb pollutants (change or dilute into a harmless form) Stock pollutants: pollutants for which the environment has little or no absorptive capacity. Important to monitor accumulations, cumulative effects management. (eg heavy metals, links between air and water pollution). Efficient allocation of a stock pollutant must account for the past accumulation in the environment. Create a burden on future generations by passing on damages. Fund pollutants: pollutants for which the environment has some capacity to absorb. Pollutants will not accumulate if the emissions rate < the absorption rate (eg organic pollutants). Important to monitor emission rates (additions to the fund) relative to absorption rate. Local pollutants: damage is experienced near the source of emission (eg fine particulate matter) Global pollutant: damage affects entire planet (eg co2)
