Country: Canada
Issue: Long range transboundary air pollution
The acid deposition occurs in Canada. Large scale pollutants and particulate matter such as SO2 and NOx are generated from USA. Strong wind current directs the pollutants towards Canada, resulting in long range transboundary air pollution. Ultimately, the phenomenon caused acid depositions in Canada. An agreement titled: “Canada-US Air Quality Agreement” was signed by both countries on March 13, 1991 to resolve this issue by committing to reduce pollutant emission within an acceptable range.
