Studies find global COVID-19 lockdowns have significantly reduced PM2.5 and NO2 pollution, but ozone up

Green Car Congress

Levels of two major air pollutants have been reduced significantly since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant—ground-level ozone—has increased in China, according to new research. Ozone is harmful to humans at ground-level, causing pulmonary and heart disease.

Study provides more insight into air pollution mechanisms that cause cardiovascular diseases

Green Car Congress

Air pollution, and fine dust in particular, is calculated to contribute to more than four million deaths each year. While the mechanisms by which air pollutants cause cardiovascular events is undergoing continual refinement, the preponderant evidence support rapid effects of a diversity of pollutants including all particulate pollutants (e.g.

A team from Rice University and the Houston Fire Department EMS has found a direct correlation between out-of-hospital cardiac arrests (OHCA) and levels of air pollution and ozone. micrograms) and ozone. Peak-time risks from both pollutants rose as high as 4.6%. Katherine B. Ensor; Loren H. Circulation. doi: 10.1161/?CIRCULATIONAHA.113.000027.

6PPD-quinone derived from tire debris is toxic to two trout species, not just coho salmon

Green Car Congress

Every time it rains, fish living downstream of storm drains are exposed to pollutants, including the tire-derived compound 6PPD-quinone, in the runoff. 6PPD is an antioxidant and antiozonant that helps prevent the degradation and cracking of rubber compounds caused by exposure to oxygen, ozone and temperature fluctuation.

Study: more stringent O3 and PM2.5 air pollution standards could save thousands of lives, greatly improve public health

Green Car Congress

In “Estimated Excess Morbidity and Mortality Caused by Air Pollution above ATS Recommended Standards, 2011-2013,” published online in the August edition of Annals of the American Thoracic Society , researchers report on the annual health benefits of meeting more protective standards recommended by the ATS for O 3 and PM 2.5.
