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.

NOVEMBER 14, 2018

The CTI will include a future rulemaking that will update the existing NO x standard which was last set in 2001 while also streamlining compliance and certification requirements. The US has made major reductions in NO x emissions, but it’s been nearly 20 years since EPA updated these standards.

Results from CHIE studies are used to inform the periodic review of National Ambient Air Quality Standards (NAAQS) for common pollutants, such as ozone and particulate matter (PM), and advise other policy decisions. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants.

Paris and London have committed to launch their data online by the end of 2017. Some diesel cars that meet the latest Euro 6 standards in reality release more NO x than a modern heavy duty truck. Consumers will therefore enjoy a far more accurate understanding of how polluting that car will be when driven on urban streets.
