Air Pollution

Lancet Planetary Health study says almost no one is safe from PM2.5

99% of the world's population is exposed PM 2.5 at unhealthy levels according to Lancet Planetary Health's recently released study. The Washington Post author Kasha Patel highlights:

In 2019, they found 0.001 percent of the global population is exposed to levels of PM 2.5 pollution that the World Health Organization deems safe. The agency has said annual concentrations higher than 5 micrograms per cubic meter are hazardous.

Air quality post-pandemic didn't improve as previously suspected

Roy Harrison, a researcher and professor at the University of Birmingham, UK, recently conducted a study to review the reductions in PM 2.5 and NO2 levels that resulted from the COVID-19 pandemic lockdowns over 11 cities. Harrison applied machine learning techniques to remove the effects of weather on the gaseous concentrations to see how the air quality had truly changed due to the lockdowns. 

Inexpensive Air Quality Sensors here for our Climate Catastrophe

As our atmosphere rapidly accepts pollutants and the planet rises in temperature, small air quality sensors are becoming more affordable and widely used.

Low-cost air quality sensors are becoming more accurate and affordable to the general public month by month. There is a grand amount of research occurring in the field so air quality sensors. Government, private industry, non-profits and community scientists are all concerned about the air pollution around the world.

Premature death from cross-state air pollution decreases from 53% to 41%

It’s widely known through the Air Quality Research Center that outdoor air pollution leads to untimely deaths throughout the world, however, a recent publication by Dr. Erwan Monier, Associate Professor of Climate Change Impacts in the Department of Land, Air and Water Resources, and associates demonstrated that many of these deaths are a result of cross-state air pollution.
