Sensing evolution

Last month we looked at global sensors leader Alphasense and their work within the Gas Safety sector. This month we take a closer look at the steps they are taking to support the global drive to improve air quality.

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.

Spore circumspection

A new study led by Imperial College London appears to find that drug-resistant mould is spreading from the environment and infecting susceptible people's lungs.

PM risk for autoimmunity

Long-term exposure to air pollution is linked to a heightened risk of autoimmune disease, particularly rheumatoid arthritis, connective tissue and inflammatory bowel diseases, finds research published online in the open access journal RMD Open.

Smart, affordable monitor

Instrument firm Oizom has launched an industrial-grade, single-parameter air quality monitor - AQBot - capable of measuring a range of gases in addition to particulate matter.

Tiny traps for toxic gases

Seemingly at the leading edge of innovation in the field of air pollution and climate change mitigation are efforts to develop materials that can detect and trap pollutant gases. In some cases, captured molecules might also be stored and reused.
