Activity at the Environmental Protection Agency office that issues scientific reports on the toxicity of chemicals has nearly ground to a halt in recent years. These assessments are needed before any new regulations on chemicals can be issued. The agency faces intense pressure from Congress and industry whenever it determines that a chemical poses a greater risk to public health than previously thought. Industry hires scientists who argue that known carcinogens such as arsenic, formaldehyde and hexavalent chromium are generally safe at currently allowable levels. The scrutiny has made it difficult for the EPA to update chemical regulations.
