'Safe' levels of carbon monoxide may still be dangerous

Data from 337 cities across 18 countries show that even slight increases in ambient carbon monoxide levels from automobiles and other sources are associated with increased mortality.
Researchers analyzed data, including a total of 40 million deaths from 1979 to 2016, and ran it through a statistical model.
The research in
The Lancet Planetary Health also shows that even short-term exposure to ambient carbon monoxide (CO) at levels below the current air quality guidelines and considered safe had an association with increased mortality.
Overall, a 1 mg/m³ increase in the average CO concentration of the previous day was associated with a 0.91% increase in daily total mortality, the study finds. This suggests reducing ambient CO concentrations through stricter control of traffic emissions and other measures could achieve considerable public health benefits. ....

A two-year assessment of particulate air pollution and sources in Kuwait.

Apr 15, 2021
Kuwait and the Gulf region have a desert, hyper-arid and hot climate that makes outdoor air sampling challenging. The region is also affected by intense dust storms. Monitoring challenges from the harsh climate have limited data needed to inform appropriate regulatory actions to address air pollution in the region.
To compare gravimetric measurements with existing networks that rely on beta-attenuation measurements in a desert climate; determine the annual levels of PM and PM over a two-year period in Kuwait; assess compliance with air quality standards; and identify and quantify PM sources.
We custom-designed particle samplers that can withstand large quantities of dust without their inlet becoming overloaded. The samplers were placed in two populated residential locations, one in Kuwait City and another near industrial and petrochemical facilities in Ali Sabah Al-Salem (ASAS) to collect PM and PM samples for mass and elemental analysis. We used positive ....

New York, April 9 : A team of researchers has found that even slight increase in ambient carbon monoxide levels from automobiles and other sources are associated with increased mortality.
The study, published in The Lancet Planetary Health, also found that even a short-term exposure to ambient carbon monoxide (CO) at levels below the current air quality guidelines and considered safe had an association with increased mortality.
These findings have significant public health implications, said researcher Kai Chen, Assistant Professor from Yale University in the US. ....
