For details on toxins and their effects on human health, please refer to the comprehensive list compiled by the Agency for Toxic Substance and Disease Registry (ATSDR) at the Centers for Disease Control and Prevention (CDC) in Atlanta, Ga. ATSDR has provided brief answers to basic questions in ToxFAQs. Many of the toxins in the ToxFAQs are found as contaminants in drinking water from tap and bottled water. For non-toxicologists there is a consumer version of the answers in a category called "for Community Members."
The ATSDR also has a informative summary of how human organs are impacted by toxins and by the following types of health issues.

Caution and Disclaimer: The science of toxins and their links to diseases is largely based on data from US Government research on rodents and anecdotal data from workplace accidents in industry. It is an evolving science and the information is correlational rather than causal. We strongly suggest that it is in your best interest to consult your doctor for professional advice on any remedial actions. Thank you.
