The National Environment Board (NEB) will beef up preventive measures against PM2.5 ultrafine dust after 17 northern provinces have seen smog pollution hit crisis levels.

Health warnings were issued on Saturday as the northern province of Lampang entered a second week contending with heavy smog from agricultural burning that has generated an excess of particulate matter smaller than 2.5 microns (PM2.5).

The Centre for Air Pollution Mitigation (CAPM) on Monday revealed that the haze pollution the country faces, especially in the northern region, will likely worsen next month, while Bangkok and its adjacent provinces will likely experience high levels of fine particulate matter (PM2.5).

A new modeling approach could enable decision-makers to reduce hazardous emissions and improve public health through more rapid design of combined climate and air-quality policies.

Background: Bushfire smoke is a major ongoing environmental hazard in Australia. In the summer of 2019–2020 smoke from an extreme bushfire event exposed large populations to high concentrations of particulate matter (PM) pollution. In this study we aimed to estimate the effect of bushfire-related PM of less than 2.5 μm in diameter (PM2.5) on the risk of mortality in Sydney, Australia from 2010 to 2020. Methods: We estimated concentrations of PM2.5 for three subregions of Sydney from measurements at monitoring stations using inverse-distance weighting and cross-referenced extreme days (95th ...
