Show answer & explanation
Correct answer: B
Concept
Chronic toxicity develops through repeated or prolonged exposure and may appear only after a latency period. Because symptoms can be delayed and influenced by dose, duration, and other exposures, linking them to one hazardous waste is often difficult.
Application
Statement I says that determining chronic toxicity from hazardous waste is not difficult. This conflicts with the long latency, mixed exposures, and confounding factors that make chronic causal assessment difficult; therefore Statement I is incorrect.
Statement II says chronic effects may be seen immediately after exposure. Immediate effects are acute effects; chronic effects generally emerge after prolonged or repeated exposure or after a latency period. Therefore Statement II is incorrect.
Contrast
Both Statement I and Statement II are correct: this assigns easy determination and immediate onset to chronic toxicity, which conflicts with both defining features.
Both Statement I and Statement II are incorrect: this reflects difficult causal determination and delayed or long-term manifestation.
Statement I is correct but Statement II is incorrect: this recognizes delayed manifestation but still treats causal determination as easy.
Statement I is incorrect but Statement II is correct: this recognizes difficult causal determination but treats a chronic effect as immediate.
Thus, both Statement I and Statement II are incorrect.
