Which of the above are persistent organic pollutants?

Answer: [D] 1, 2, 3 & 4

Persistent organic pollutants (POPs) are groups of organic or highly toxic chemicals which are persistent in environment. They can also travel great distances through natural processes and can accumulate in the fatty tissue of living things. POPs generally come from pesticides or as industrial by-products. These 12 chemicals, commonly called “dirty dozen” are aldrin, chlordane, DDT, dieldrin, dioxins, endrin, furans, heptachlor, hexachlorobenzene, mirex, PCBs, and toxaphene.
