Health Canada has posted a new guideline for levels of benzene in drinking water. The Guideline Technical Document on Benzene in Drinking Water now proposes levels of 0.001 mg/L. Previous recommended levels were 0.005 mg/L as posted on the Canadian Council of Ministers of the Environment web site(http://www.ccme.ca/sourcetotap/benzene.html).
Benzene is a clear, colourless liquid that is highly flammable. It is used in making plastics, rubber and synthetic fabrics such as nylon and polyester. It is also used as a solvent in printing, paints and dry cleaning, and is found in gasoline. The main source of benzene in the environment is from emissions from vehicle engines.
The chemical is a documented human carcinogen most notably causing leukemia after high exposures and is toxic to freshwater fish, invertebrates, and aquatic plants.
