Ozone, at ground zero
ozone pollution has damaged six million tonnes of crops in India in 2005, says a research published in Geophysical ResearchLetters. Ground-level ozone is formed in the air due to reactions between nitrogen oxides and hydrocarbon (emitted from vehicles and other sources) in the presence of sunlight. Being a strong oxidant, ozone damages lungs and vegetation. It is also the main component of smog. "India could feed 94 million people with the lost wheat and rice crops," said Sachin Ghude, scientist at the Indian Institute of Tropical Meteorology, Pune, and lead author of the study.
