Study finds association between air pollution, coronary atherosclerosis in Chinese population

Green Car Congress

Researchers from the University at Buffalo (UB), with colleagues in the US and China, have provided pathophysiologic evidence of the effect of air pollution on cardiovascular disease in China. Their findings also suggests that China may need to revise its standard for one type of pollutant. —first author, Meng Wang.

Study links increased black carbon pollution to increase in cases of lung adenocarcinoma worldwide

Green Car Congress

An international team of scientists, led by NTU Singapore, has linked increased air pollution to an uptick in cases of lung adenocarcinoma (LADC) worldwide. This study, done in collaboration between NTU and the Chinese University of Hong Kong, showed that a 0.1 Black carbon is a pollutant that is classified as under PM 2.5.

Ice core data show why air pollution is dropping more slowly in US and Western Europe despite lower sulfur emissions

Green Car Congress

Low-sulfur gasoline standards and regulations on power plants have successfully cut sulfate concentrations in the air, reducing the fine particulate matter that harms human health and cleaning up the environmental hazard of acid rain. —co-author and leader of SE-Dome ice core project Yoshinori Iizuka, Hokkaido University.

10-year study shows how air pollution fosters heart disease; accelerated plaque build-up in arteries

Green Car Congress

Long-term exposure to particulate air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. Participant-specific pollutant concentrations averaged over the years 2000–10 ranged from 9.2–22.6 The study is published in The Lancet. and NO x between 1999 and 2012. μg PM 2.5 /m

UB study finds link between ambient ozone exposure, artery wall thickness

Green Car Congress

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. While the study finds an association between air pollution and atherosclerosis, researchers aren’t clear on why. —Meng Wang. —Meng Wang.

Study: even relatively low levels of air pollution appear to affect a child’s lungs

Green Car Congress

In a paper published in the American Journal of Respiratory and Critical Care , researchers report that children exposed to higher levels of air pollution—even if relatively low—including fine particulate matter (PM 2.5 ) and soot (black carbon), had worse lung function than those living in less polluted areas. mL; -43.9,
