Air pollution didn't drop during COVID-19 lockdown in India as thought: Study

Firstpost  

The study says that blue skies and an absence of visible smog can be deceiving and hide pollutants that could potentially cause health issues Toronto: 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. “Our research shows the decline in local emissions had less influence on the decrease in air pollutants than first thought,” said Leigh Crilley, a postdoctoral researcher at York University. “To accurately quantify the impact of the COVID-19 lockdown on air pollutant levels, meteorology and atmospheric chemistry needs to be considered in addition to emissions,” Crilley said.
