New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide emissions, over Italy.

Scientists aim to better understand the effects of carbonaceous aerosol on air pollution and climate change.

In 2016, scientists at MIT and elsewhere observed the first signs of healing in the Antarctic ozone layer. 

Lanzhou was one of the most air-polluted cities in China over the past few decades due to its narrow river valley topography and industrial emissions.

Ever since the industrial revolution, nitrogen fixation induced by human activities has considerably altered the nitrogen cycling process on the Earth.

Researchers found that PM2.5 showed different pollution characteristics and mechanisms under the artificial control and synoptic situations.

In Senegal, groundnut and maize are commonly contaminated with highly toxic, cancer-causing chemicals called aflatoxins, which are produced by fungi in the genus Aspergillus when they infect crops.

Professor Kenneth Leung and his research team have been monitoring organotin pollution in the marine environment of Hong Kong since 2004.

A Washington State University research team has found that nanoscale particles of the most commonly used plastics tend to move through the water supply, especially in fresh water, or settle out in wastewater treatment plants, where they end up as sludge, in landfills, and often as fertilizer.

Excess electrons could help break the strong chemical bonds in products that contaminate water supplies.
