Pollutants are among the most visible effects of human occupation on Earth and, whether obvious or not, they are directly and indirectly harming human health and our environment.
Some, such as mercury, are naturally occurring, while many others are human-caused. The challenge for government is to minimize the risks posed by their use, storage and release, and, if human-caused, to accelerate their elimination.
Environment Canada is committed to reducing the impact of pollutants on our air, water and land. The department offers programs and practical guidance to ensure safe handling of pollutants and uses legislation and regulations to prevent their inappropriate use or release into our environment.
