People who use pesticides or regularly come in contact with them must understand the relative toxicity and potential health effects of the products they use. Their effect on health could occur through at least two mechanisms: first, by increasing the presence of heavy metals in air, water, soil, and food, and second, by changing the structure of the chemical.

The TLVs are guidelines for occupational exposure to hazardous chemicals and are published in a booklet called Threshold Limit Values (TLVs) for Chemical Substances and Physical Agents and Biological Exposure Indices (6). Acute toxicity is measured as the amount or concentration of a toxicant-- the a.i.--required to kill 50 percent of the animals in a test population. Trainer may want to provide examples of venomous animals, such as snakes, spiders, etc., and poisonous animals, such as puffer fish, or oysters, which may be toxic to some individuals when contaminated with vibrio vulnificus.

As the lead agency for implementing the health-related guidelines of CERCLA, ATSDR assesses the presence and nature of health hazards at specific Superfund Sites, to help prevent or reduce further exposure and the illnesses that result from such exposures, and to expand the knowledge-base about health effects from exposure to hazardous substances. ACGIH is a professional organization that produces a listing of Threshold Limit Values (TLV) and Biological Exposure Indices (BEI) for several hundred chemicals, updating them every year.

People who use pesticides or regularly come in contact with them must understand the relative toxicity and potential health effects of the products they use. Their effect on health could occur through at least two mechanisms: first, by increasing the presence of heavy metals in air, water, soil, and food, and second, by changing the structure of the chemical.
