Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Dioxins and other chlorinated hydrocarbons accumulate to dangerous levels in fish and fish-eating birds.
Statement II:Dioxins are highly toxic; even extremely low concentrations can cause birth defects, genetic disorders and cancer.
ABoth Statement I and Statement II are correct ✓ Correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct
Correct answer: (A) Both Statement I and Statement II are correct
Explanation
Dioxins and related chlorinated hydrocarbons do build up to dangerous levels in fish and fish-eating birds, so Statement 1 holds.
They are fat-soluble and persistent, so they accumulate up aquatic food chains.
Statement 2 is also correct because dioxins are extremely toxic even at tiny concentrations.
Very low doses can cause birth defects, genetic disorders and cancer.
Both statements are accurate.
Dioxins form as byproducts of waste burning and certain industrial processes.
