Ecotoxicity, the subject of study of the field of ecotoxicology (a portmanteau of Ecology and Toxicology) refers to the potential for biological, chemical or physical stressors to affect ecosystems. Such stressors might occur in the natural environment at densities, concentrations or levels high enough to disrupt the natural biochemistry, physiology, behavior and interactions of the living organisms that comprise the ecosystem.
Ecotoxicology has been defined as, "the branch of toxicology concerned with the study of toxic effects, caused by natural or synthetic pollutants, to the constituents of ecosystems, animal (including human), vegetable and microbial, in an integral context".
In Canada, there is no law requiring manufactures to state the health and environmental hazards associated with their cleaning products. Many people buy such products to support a clean and healthy home, often unaware of the products ability to harm both their own health and the surrounding environment. "Canadians spend more than $275 million on household cleaning products in a year" Chemicals from these cleaners enter our bodies through air passageways and absorption through the skin and when these cleaning products are washed down the drain they negatively affect aquatic ecosystems. There are also no regulations in place stating that the ingredients be listed on labels of cleaning products leading the users to be ultimately unaware of the chemicals they expose themselves and their surrounding environments to.
The organic compound 2-Butoxyethanol, commonly found in glass cleaners, laundry stain removers, windshield wiper fluid, oven cleaners, and rust removers has been proven to cause reproductive problems in laboratory experiments.
