Some lab experiments may use chemicals that are considered teratogens. If you are pregnant, think you are pregnant or trying to get pregnant, please contact your professor or lab instructor to find out if any of these chemicals may be used in your lab during the semester.
In 1986, California passed Proposition 65, the Safe Drinking Water and Toxic Enforcement Act. This Proposition shifts the burden of proof in the regulatory process from government to industry. Use of chemicals known to cause cancer or reproductive toxicity is no longer considered "innocent" until proven "guilty" of harming public health by governmental agencies. Identified hazards are placed on a list and automatically become subject to the Act's warning requirements (12 months after listing) and discharge prohibition (20 months after listing). Exemptions from these requirements are allowed only if the business responsible for an exposure or discharge can demonstrate that the amount of chemical in question poses "no significant risk."
