A toxicologist wants people to cut down on liquid soaps and toothpastes with anti-bacterial ingredients.
A study by the Cawthron Institute says one anti-bacterial and anti-fungal compound, triclosan, is found in everything from liquid soaps to toothpastes.
A researcher Louis Tremblay says that when the chemical is washed down the drain, it attacks bacteria used in sewage treatment ponds and in the natural environment.
He says consumers should steer clear of products with anti-bacterial on the label and he wants to see an environmental rating system for household chemicals, similar to the energy efficiency ratings on home appliances.
