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. —Guy Brasseur.

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. 6PPD is used industry-wide to help tires resist degradation and cracking. The LC 50 s in brook trout (24 h) and rainbow trout (72 h) were 0.59 g/L, respectively.

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. course, fine, ultrafine particles) and gaseous pollutants such as ozone, on vascular function.

C above pre-industrial levels. We see it as similar to the ozone hole problem, where we really needed a tight, science-based focus on the limits to human inputs to the system--and howthose inputs affected the ozone layer's ability to keep people safe. C by the year 2100 , according to Climate Action Tracker.
