Two of the most damaging pollutants in our environment are mercury and polychlorinated biphenyls (PCBs).
The challenge with mercury - a natural element whose unique properties have been harnessed by humans for centuries - is to ensure levels in our environment do not exceed what would be expected from natural processes.
Although the Government of Canada made import, manufacture or sale of PCBs illegal in 1977, the challenge now is to speed up the pace of destruction of existing PCBs.
