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

Green Car Congress

JANUARY 3, 2019

In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. Over the course of five years, PM 2.5

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.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

AUGUST 21, 2009

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.
