Which of the following is an ozone-depleting pesticide?
(1) D.D.T.
(2) Benzene
(3) Methyl bromide
(4) Ethylene ozonide
Answer: (3) Methyl bromide- is considered to be a significant ozone-depleting substance (ODS) by atmospheric scientists. While methyl bromide is a natural substance, the additional methyl bromide added to the atmosphere by humans contributes to the thinning of the ozone layer, allowing increased UV radiation to reach the Earth’s surface, with a potential impact not only on human health and the environment but to agricultural crops as well.
