The persistence of DDT in the environment and its biomagnification are mainly due to the fact that DDT:
Ais an inorganic salt that dissociates completely
Bis fat soluble and is not readily metabolised or excreted
Cis converted to harmless carbon dioxide by soil bacteria within days
Dis highly soluble in water and quickly washed away
Answer: B
DDT is a non-biodegradable chlorinated organic compound that dissolves in fats. It accumulates in fatty tissue instead of being excreted, so its concentration rises along the food chain.
