EDTA

Also known as ethylene-diamine-tetra-acetic and diammonium EDTA.

Skin irritant. Irritating to the mucous membranes, leading to allergies, asthma, and skin rashes. Does not readily biodegrade. Binds with heavy metals trapped in our lakes and streams, thereby activating the metals and causing them to reenter the food chain. Found in laundry detergents.
