Aerosol appraisal
What is purported to be the first global map of cargo ship pollution has revealed interesting effects including the apparent impact of fuel regulations. The "ship tracks" in clouds, which the study measured, also appear to be helpful in explaining how particulate matter both interacts with clouds and affects global temperatures.

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.
Smoking out the dangers
Increasingly large and intense wildfires in the Pacific Northwest of the US are altering the seasonal pattern of air pollution and causing a spike in unhealthy pollutants in August, new research appears to find. The smoke seems to be undermining clean air gains, posing potential risks to the health of millions.
The secret life of clouds
Even the finest particles of pollution influence the process of cloud formation and the rainfall regime, it seems. A study conducted in Manaus, in the Brazilian state of Amazonas, appears to show that oxidation leads small aerosols expelled by factories and car exhausts, for example, to grow very rapidly, reaching up to 400 times their original size, and that this affects raindrop formation.
Destined to be a new piece of furniture?
A new air purifier is seemingly designed - somewhat uniquely - to catch airborne dust before it settles on floors and surfaces. Announced in February by Swedish firm Blueair, the DustMagnet™ also seems unusual in its departure from anything machine-like in appearance having been designed to look like a piece of furniture.
Time to get real?
Recent years have seen a concerted drive to better understand and monitor various chemical and physical agents in the workplace, including things like machine vibration. One recent development along these lines is the drive to provide real-time monitoring of dust, as instrumentation firm Casella explains here.
