Washington, DC 20210 Todays decision follows the EPAs announcement last year that it had granted a pesticide industry request to end long-running safeguards legally mandated to protect young children from pyrethroids, which have been shown to cause learning deficiencies. Acute toxicity is determined by examining the dermal toxicity, inhalation toxicity, and oral toxicity of test animals.

The CDC Centers that deal with environmental health are the National Center for Environmental Health (NCEH) and the National Institute for Occupational Safety and Health (NIOSH) (2). Acute toxicity of a pesticide refers to the chemical's ability to cause injury to a person or animal from a single exposure, generally of short duration.

The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. The lower the LD50 or LC50 of a pesticide product, the greater its toxicity to humans and animals. There are ten regional EPA offices throughout the United States, with EPA headquarters located in Washington, D.C. Each regional office is responsible within selected states for implementing the agencys programs, considering regional needs and implementing federal environmental laws.

Any harmful effects that occur from small doses repeated over a period of time are termed chronic effects. The common chemical name of the active ingredient followed by an example of a trade name is listed in the first column. Information presented here is for preliminary planning only.

Additionally, the LD50 and LC50 values are based on a single dosage and are recorded in milligrams of pesticide per kilogram of body weight (mg/kg) of the test animal or in parts per million (ppm). Please check labels for pest insects controlled before use. Web site: https://www.epa.govexternal icon, U.S. Food and Drug Administration (FDA) In response to the EPAs proposal to reapprove paraquat, 52 farmworker, public health, environmental justice, conservation and farmer advocates joined a letter urging the EPA to ban the chemical because of its substantial and demonstrated risks.
