Carbon monoxide pollution may cause loss of consciousness or death in the exposed individual. For such an event to occur, the likely minimum percentage saturation level of carboxyhaemoglobin in the human blood would be:कार्बन मोनोक्साइड प्रदूषण के कारण उद्भासित व्यक्ति अचेत या मर भी सकता है। ऐसा होने के लिए मानव रक्त में कार्बोक्सीहीमोग्लोबिन के संतृप्त स्तर को न्यूनतम कितना प्रतिशत होना चाहिए?

Show answer & explanation
Correct answer: D. 60%
Explanation
CO binds haemoglobin to form carboxyhaemoglobin (COHb). Around 5–15% COHb causes mild effects (as in smokers), about 30% causes headache, dizziness and weakness, while coma, loss of consciousness and death occur at roughly 50–60% or above. Among the options, 60% is the level for such an event.CO हीमोग्लोबिन से जुड़कर कार्बोक्सीहीमोग्लोबिन (COHb) बनाता है। लगभग 5–15% COHb से हल्के प्रभाव (जैसे धूम्रपान करने वालों में), लगभग 30% पर सिरदर्द, चक्कर और कमज़ोरी होती है, जबकि कोमा, अचेतावस्था और मृत्यु लगभग 50–60% या अधिक पर होती है। विकल्पों में से ऐसी घटना का स्तर 60% है।More People, Development and Environment questions
