The most common source of chlordane exposure is from eating food contaminated by chlordane. Chlordane remains in the food supply because much of the farmland was treated with chlordane in the 1960s and 1970s and it may remain in some soil for over 20 years. However, since chlordane has been banned, the levels in soils would be expected to decrease with the passage of time. Chlordane may also be found in fish and shellfish caught in chlordane contaminated waters.
A survey conducted by the Food and Drug Administration (FDA) determined daily intake of chlordane from food to be 0.0013 μg/kg of body weight for infants and 0.00050.0015 μg/kg of body weight for teenagers and adults.
Chlordane can enter the body through the skin if skin contact occurs with contaminated soils, through the lungs if breathed in with contaminated air, and through the digestive tract if swallowed. Uptake through the skin and digestive tract increases if chlordane is in an oily mixture, which might occur at hazardous waste sites.
The amount of chlordane that enters the body depends on the concentration in air, food, or water, and the length of exposure. Most chlordane that enters the body leaves in a few days, mostly in the faeces, and a much smaller amount leaves in the urine.
