Correct answer: C. Acids of arsenicआर्सेनिक के अम्ल
Explanation
In groundwater arsenic occurs in dissolved inorganic form as arsenite and arsenate, that is as the oxyacids arsenous acid (H₃AsO₃) and arsenic acid (H₃AsO₄) and their ions. Hence the pollution is attributed to the acids of arsenic. Arsenic sulphides and nitrates are not the mobile species responsible for contaminated aquifers.भूजल में आर्सेनिक घुलित अकार्बनिक रूप में आर्सेनाइट तथा आर्सिनेट के रूप में, अर्थात् ऑक्सी-अम्लों आर्सिनस अम्ल (H₃AsO₃) तथा आर्सेनिक अम्ल (H₃AsO₄) और उनके आयनों के रूप में पाया जाता है। अतः यह प्रदूषण आर्सेनिक के अम्लों के कारण माना जाता है। आर्सेनिक के सल्फाइड तथा नाइट्रेट दूषित जलभृतों के लिए उत्तरदायी गतिशील रूप नहीं हैं।More People, Development and Environment questions
