Governments are increasingly adopting policies on air quality, but gaps hinder progress towards cleaner air

Source: UN environment program A global review of policies and programmes to improve air quality shows that over the past five years more countries have adopted policies on all major polluting sectors. Yet large gaps in implementation, financing, capacity, and monitoring mean that air pollution levels remain high. This data is published today, the International Day …

Exposure to pollution during pregnancy is linked to asthma in preschoolers as well as pregnancy loss

Source: airqualitynews.com Exposure to fine dust (PM2.5) is linked to asthma in preschoolers. The research looked at 376 mothers’ homes, and found that those homes with PM2.5 exposure had an 18% chance of the children being diagnosed with asthma after 3 years, compared with 7% children overall in the U.S. Additionally, the research suggests that …

Plume of Sahara dust causes spike in European air pollution

The Copernicus Atmosphere Monitoring Service highlights that their air quality forecasting shows that a substantial plume of Saharan dust is travelling north; from Spain to France and the Benelux countries, possibly reaching as far as Norway. This will likely lead to a significant drop in air quality in the affected regions. The high concentrations of …

EU sues more countries over air pollution, nature and water

Brussels has set legal limits on particulate matter since 2005, resulting in a series of legal actions against countries flouting the rules. Air pollution in Europe has eased in the last decade, but remains the continent’s biggest environmental health risk. Fine particulate pollution caused 379,000 premature deaths in the EU in 2018, according to the …

Fine dust causes thinner brain, linked to dementia

A Korean study found that fine dust can make the brain shrink and cause cognitive decline. Using brain MRI, the researchers measured the subjects’ cortical thickness and subcortical volume. Then, they compared the values with the concentration of air pollutants in the subjects’ residential areas. The results showed that the higher concentration of air pollutants, …

Higher PM2.5 concentrations may link to Alzheimer disease

Higher PM2.5 concentrations appear to be associated with brain amyloid-ß plagues, a signature characteristic of Alzheimer disease. This suggests the need to consider particulate matter more thoroughly in public health policy decisions. This links back to previous articles, which underline that particulate matter is not only detrimental to the respiratory system, but to organs throughout …
