Researchers suggests high level of air pollution in Northern Italy a co-factor in COVID-19 mortality rate

Green Car Congress

Researchers from the University of Siena in Italy and Aarhus University in Denmark are suggesting that the high level of pollution in Northern Italy should be considered an additional co-factor of the high level of COVID-19 fatalities recorded in that area. Environmental Pollution , doi: 10.1016/j.envpol.2020.114465. 2020.114465.

International study finds air pollution leads to millions of hospital visits for asthma attacks worldwide

Green Car Congress

Air pollution—specifically PM 2.5 , ozone and NO 2 —could be to blame for up to 33 million emergency asthma attack visits to hospital a year, according to a new open-access study published in the journal Environmental Health Perspectives. Anthropogenic emissions were responsible for ?37% 37% and 73% of ozone and PM 2.5

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems.

Study finds power law scaling relationship between urban population and NO2 pollution

Green Car Congress

The approximate linear relationship for each region is notable, suggesting that the dependence of urban NO 2 pollution upon population follows a power law scaling with population. These regions contain two-thirds of total global anthropogenic NO x emissions. Credit: ACS, Lamsal et al. Click to enlarge. for India to 0.66

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. These observations may also assist air quality managers in assessing the most effective approaches to emission reduction programs that will improve air quality.

DISCOVER-AQ project to begin flights to enhance measurement of ground-level air-quality from space

Green Car Congress

The flights will be supported by the US Environmental Protection Agency (EPA) and will aid EPA in monitoring pollutants. The fundamental challenge for satellites measuring air quality is to distinguish between pollution near the surface and pollution higher in the atmosphere. Measuring pollution from space.
