“An Indian Institute of Technology, Kanpur study has found alarming details on Delhi’s air pollution, including the presence of polycyclic aromatic hydrocarbons (PAH), that are extremely toxic chemicals and a product of emissions from diesel-run vehicles among others.
Apart from PAH, the draft report, that has been submitted to the Supreme Court, identifies the sources of suspended particulate matter PM 2.5, namely road dust (38%), vehicles (20%), domestic fuel burning (12%) and industrial point sources (11%).
Anumita Roychowdhury, head of Centre for Science and Environment (CSE’s) clean air campaign, said that even traces of PAH, which is anyway found in “very small quantity”, can be extremely deadly and can reach harm to a foetus as well.“PAH are toxic gases and a potent carcinogen, meaning exposure to them can cause cancer. It comes mainly from sources that use diesel as fuel which include diesel-run cars, gen sets, trash burning,” she said.” Live Mint. Read it on delhiair.org.
