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. For comparison, columns over the same time periods are shown for 2019. —Guy Brasseur.

German-Chilean consortium investigating new ways of reducing arsenic in copper concentrates: ReAK

Green Car Congress

Chile is the world’s top copper producer (27% of global production) and exporter. The continual exploitation of ore reserves leads to the necessity of mining ores from deeper parts of deposits, often with increasing mineralogical complexity. In 2021 alone, Chile mined about 5.6 —Anna-Lisa Bachmann.

Study estimates ~4M children worldwide develop asthma each year because of NO2 air pollution

Green Car Congress

NO 2 is just one component of air pollution, which is made up of many pollutants (including particulate matter, ozone, carbon monoxide), which are known to have numerous adverse effects on health. The researchers estimate that most children lived in areas below the current WHO guideline of 21 parts per billion for annual average NO 2.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?
