How can chlorpyrifos affect my health?
Breathing the air in an area in which chlorpyrifos has recently been sprayed may produce a variety of effects on the nervous system including headaches, blurred vision, watering of the eyes (called lacrimation), excessive salivation, runny nose, dizziness, confusion, muscle weakness or tremors, nausea, diarrhea, and sudden changes in heart rate. The effect depends on the amount in the air and length of time exposed. Ingesting chlorpyrifos orally through contaminated food containers or, in the case of children, putting objects of hands in their mouth after touching chlorpyrifos, may cause similar symptoms. Exposure to high levels may cause severe sweating, loss of bowel control, severe muscle tremors, seizures, loss of consciousness (coma), or death. There is no information at present to show that chlorpyrifos either effects the ability of humans to reproduce or causes human birth defects.
