Ground level ozone is a highly reactive gas commonly found in urban and suburban environments, formed when pollutants react in sunlight. Current air quality thresholds (in micrograms per cubic meter of ambient air) range from 100 ?g/m g/m 3 (WHO), 120 ?g/m g/m 3 (European Union directive), 140 ?g/m Vicedo-Cabrera et al.

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

A trio of recently published studies from a team of University of Toronto engineers has found that air pollution could be spreading up to three times farther than thought, contributing to varying levels of air quality across cities. These roads, says Evans, range from 10-lane highways to most four-lane streets with steady traffic.

An international team of researchers has used satellite images to map urban growth between 1985 and 2015. Urban area dynamics during 1985–2015 at the global and continent scales. The slope is derived from linear regression, with an uncertainty range at the 95 th confidence level. b, Slopes of urban area growth over continents.

In connection with the effects of the COVID-19 pandemic, satellite measurements made headlines showing how much the air pollutant nitrogen dioxide (NO 2 ) had decreased in China and northern Italy. In 2018/2019, for example, various measures were taken in Germany, ranging from a reduction in the number of lanes (e.g. in Stuttgart).
