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

Green Car Congress

MAY 12, 2020

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.

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.

The $461,000-project, titled “Heterogeneous Aging Mechanisms of Combustion and Biomass Burning Emissions,” will focus on how gases, such as ozone, react with pollutants emitted from power plants and forest fires. Guzman and his students will study how these pollutants are transformed on surfaces by oxidizing atmospheric gases.

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.

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

New research by a team from the US, China and Japan focusing on the Houston, Texas area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea. ““The very existence of the Houston area favors stagnation.”

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. In almost all previous projections for climate, tipping events like these were far in the future.

Furthermore, this would also deliver a net annual reduction of at least 200 MtCO 2 e from short-lived climate pollutants in 2030 (using GWP-100 values). Next-generation standards would target new reductions in emissions of NO x and non-methane hydrocarbons (HC), which are precursors to ozone and secondary particulate matter.
