Studying tiny plastics in the air

Large pieces of plastic can break down into nanosized particles that often find their way into soil and water. Perhaps less well known is that they can also float in the air. It's unclear how nanoplastics impact human health, but animal studies suggest they're potentially harmful. Researchers have developed a sensor that detects these particles and determines the types, amounts and sizes of the plastics using colourful dot films.

A fresh crop of data

Record hot temperatures in the UK over the summer caused significant changes to the levels of harmful pollutants such as ozone and particulate matter, prompting a number of novel observations by the National Centre for Atmospheric Science (NCAS).

Report clarifies urban air pollution patterns worldwide

Late August saw the release of “Air Quality and Health In Cities”, the latest edition of The State of Global Air report, produced annually by the US Health Effects Institute. It attempts a snapshot of air pollution exposure in over 7000 cities worldwide, and its impact on health. Standout findings this year include a clearer picture of PM2.5 and NO2 pollution, with fine particles seeming to be an affliction of the world's poorer regions especially, while NO2 is a problem for city dwellers everywhere.

Community-led science

Residents of Belmont County in eastern Ohio had long suffered from headaches, fatigue, nausea and burning sensations in their throats and noses. They suspected these symptoms were the result of air pollution from fracking facilities that dominate the area and the subsequent investigation offers a powerful example of what can be achieved by citizen scientists.
