In Canada, there are many laws and standards in place to protect us from the risks of potentially harmful chemicals. In most cases, levels of chemicals in the environment are well below those that are harmful. Under certain conditions however, some chemicals may pose a risk to human health. This depends on the type of chemical, the amount in question, the length of time a person is exposed to the chemical and when the exposure occurred, and the route of exposure (i.e., through food, water, air, etc.).
