WPS safety concept: pesticide hazards

• Hazards of pesticides resulting from toxicity and exposure, including:

– Acute effects– Chronic effects– Delayed effects– Sensitization

Hazard = Exposure x Toxicity

• High exposure90% = 100% x

90

• No exposure0% = 0% x 90

How can pesticide exposure occur?

Mixing/Loading Application

Plant residues

Three farm workers gave birth to infants with birth defects. Environmental Health Perspectives, 2007, ehponline.org

Insecticide: farm worker applied a carbamate insecticide for several days. He became nauseous, dizzy, weak, and had a headache. Michigan pesticide surveillance report, 2005

Herbicide: a worker was spraying glyphosate, the end of the hose came off and some sprayed on his mouth. He became nauseous and vomited. Michigan pesticide surveillance report, 2005

Fungicide: farm worker mixing fungicide rested his arm on a spill, it became red, irritated, and very itchy.

Michigan pesticide Surveillance report, 2005

Toxicity is…..

• The potential of a chemical to be poisonous

• Expressed as LD50

– Lethal dose for 50% of the population
