What happens to heptachlor and heptachlor epoxide when they enter the environment?
• Heptachlor doesn’t dissolve easily in water; heptachlor epoxide dissolves more easily. • They stick strongly to soil particles and evaporate slowly to air. • Heptachlor epoxide can stay in the soil and water for many years. • Plants can take up heptachlor from the soil. Levels of heptachlor and heptachlor epoxide can build up in the tissues of fish and cattle.
