Correct answer: B. Volatile Organic Compoundsवाष्पशील कार्बनिक यौगिक
Explanation
Aeration (air stripping) brings water into contact with a large volume of air so that dissolved substances with high vapour pressure pass into the gas phase. It therefore works best on volatile organic compounds (and on dissolved gases such as H₂S, CO₂). Persistent organic pollutants, metals and inorganic ions are non-volatile and need adsorption, precipitation or ion exchange instead.वातन (वायु-अपाकर्षण) में जल को वायु की बड़ी मात्रा के संपर्क में लाया जाता है जिससे उच्च वाष्प दाब वाले घुले पदार्थ गैस प्रावस्था में चले जाते हैं। अतः यह वाष्पशील कार्बनिक यौगिकों (तथा H₂S, CO₂ जैसी घुली गैसों) पर सर्वाधिक प्रभावी है। चिरस्थायी कार्बनिक प्रदूषक, धातुएँ और अकार्बनिक आयन अवाष्पशील हैं और उनके लिए अधिशोषण, अवक्षेपण या आयन विनिमय आवश्यक होता है।More People, Development and Environment questions
