Air pollution linked to increased risk of getting sick from Covid-19: Study

Long-term exposure to air pollution is associated with an increased risk of developing COVID-19 among people who get infected with the SARS-CoV-2 virus, according to a study conducted in Spain. The research, published in the journal Environment Health Perspectives on Wednesday, provides further evidence on the health benefits of reducing air pollution, and highlightS the influence of environmental factors on infectious diseases.

Covid lockdown in India didn't cut air pollution as much as thought: Study

Air quality in India did not improve as much during the first COVID-19 lockdown as originally thought, according to a study which found that ozone levels increased even as other pollutants decreased. The researchers at York University in Canada noted that observational data shows air pollution in India decreased drastically in the first COVID-19 lockdown last year when emissions from vehicles naturally declined. However, they noted that blue skies and an absence of visible smog can be deceiving and hide pollutants that could potentially cause health issues. The study, published in the journal Environmental Science: Processes & Impacts, found that some air pollutants didn't drop nearly as much as first thought and even more surprising was that ozone levels increased even as other pollutants decreased. The air looked much cleaner, but that allowed more sunshine to get through, creating conditions for ozone (O3) to increase up to 30 per cent, according to the researchers. "Our ...
