Automotive vehicles have emerged as a major source of Chi’s air pollution, a new report released by the Ministry of Environmental Protection (MEP)said on Saturday. Chi had 295 million automotive vehicles on its roads as of the end of last year, emitting pollutants weighing about 44.725 million tonnes, down 1.3 per cent year on year, Xinhua reported. Alysis of air pollutants of 15 major Chinese cities showed that local mobile emitters, a category that includes vehicles, contributed to about 13.5 per cent to 41 per cent of total fine particle concentration, according to Liu Bingjiang, a senior official with MEP. The MEP will enhance supervision on the production, use and elimition of automotive vehicles to reduce air pollution, Liu added. (IANS)
