Given below are two statements:
Statement I: Chronic toxicity caused due to hazardous wastes is not difficult to determine.
Statement II: Chronic effects may be seen immediately after the exposure.
In the light of the above statements, choose the most appropriate answer from the options given below:नीचे दो कथन दिए गए हैं:
कथन I: संकटपूर्ण अपशिष्टों से उत्पन्न दीर्घकालिक (क्रॉनिक) विषाक्तता का निर्धारण कठिन नहीं है।
कथन II: दीर्घकालिक प्रभाव उद्भासन (exposure) के तुरंत बाद देखे जा सकते हैं।
उपर्युक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सर्वाधिक उपयुक्त उत्तर चुनिए:

Correct answer: B. Both Statement I and Statement II are incorrectकथन I तथा कथन II दोनों ग़लत हैं
Explanation
Chronic toxicity results from prolonged low-dose exposure, and because of the long latency and many confounding factors it is in fact very difficult to determine — so Statement I is incorrect. Chronic effects by definition appear only after long or repeated exposure; effects seen immediately are acute, not chronic — so Statement II is also incorrect. Hence both statements are incorrect.दीर्घकालिक विषाक्तता दीर्घ अवधि तक अल्प मात्रा के उद्भासन से उत्पन्न होती है और लंबी प्रसुप्ति-अवधि तथा अनेक भ्रामक कारकों के कारण उसका निर्धारण वस्तुतः अत्यंत कठिन होता है — अतः कथन I ग़लत है। दीर्घकालिक प्रभाव परिभाषा से ही लंबे या बार-बार के उद्भासन के बाद ही प्रकट होते हैं; तुरंत दिखने वाले प्रभाव तीव्र (acute) होते हैं, दीर्घकालिक नहीं — अतः कथन II भी ग़लत है। अतः दोनों कथन ग़लत हैं।More People, Development and Environment questions
