Answer:
(a) The type of contamination affecting fruits and vegetables that feed most of Delhi’s population is not pesticides, but a toxic mix of industrial effluents that are contaminating the fruits and vegetables that are being grown on the river’s bed.
(b) The outer layers of leafy vegetables should be discarded before consumption to do away with chemical residue. Alternately these vegetables can be dipped in ozonated water, soaked in diluted vinegar before rinsing, or even blanched in hot water before washing.
(c) TERI findings showed high toxic levels of metals (nickel, lead, manganese chromium, zinc) in many water samples, sometimes ten times the accepted limits. Water near thermal plants had mercury concentration as high as 200 times above the required level.
