Chemical hazards and environment – UGC NET Question

Statement D is the only wrong statement because many chemicals can and do move between air, water and soil through processes such as volatilisation, deposition and leaching. Persistent pollutants can travel long distances and shift between media. Statements A, B, C, E and F correctly describe bioaccumulation, safety practices, information tools, occupational risks and international regulation. Therefore, identifying D alone as wrong is the correct answer.

Option A:
Option A is incorrect as it classifies both A and D as wrong, even though A accurately explains the behaviour of persistent organic pollutants in food chains. Grouping a true statement with a false one makes this option invalid.

Option B:
Option B is incorrect because it marks C and D together as wrong. C is actually correct in noting that labels and safety data sheets communicate essential hazard information to users, so including it among wrong statements is unjustified.

Option C:
Option C is correct since it isolates D, the sole clearly incorrect statement denying cross-media movement of chemicals. It implicitly affirms that all other statements accurately reflect environmental health principles.

Option D:
Option D is incorrect as it groups D with E, even though E is a true statement about occupational exposure affecting workers’ health. Treating E as wrong contradicts workplace health and safety evidence.
