Answer to Question 1

A toxic chemical is one that is poisonous or injurious to humans and other animals.
Acute toxicity is a measure of how poisonous a pesticide is after a single exposure.
Pesticides are generally rated according to acute toxicity. Chronic toxicity is a measure of
how poisonous a pesticide is over a period of time and after repeated exposure. Chronic
toxicity is a danger of chemicals that accumulate in the body, such as chlorinated
hydrocarbons.



Answer to Question 2

Signal words are intended to alert the user to the toxicity of a pesticide. Three signal
words are DANGER, meaning highly toxic; WARNING, meaning moderately toxic; and
CAUTION, meaning slightly toxic or relatively nontoxic.
