Used to control mosquitoes and termites prohibited in 1987

Answer 15

• Metals
• persistent organic pollutants (POPS)
• chemicals that persist inn the environment, Dioxins DDT, PCBs, Furans, orgonochlorine pestides
• lead :widely distributed in environment, when used as gasoline addictive and impaired your toxicity
