Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. There was so much particulate matter in Chinese cities that it stunted the ozone production.

China study connects ozone pollution to cardiovascular health

Green Car Congress

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The findings associated ozone exposure with markers of platelet activation and increased blood pressure.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Most of the two countries’ sulfur dioxide emissions come from coal-fired power plants and coal-burning factories.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.
