Air pollution has been shown to have a negative effect on the prognosis of ischemic stroke, or stroke caused by reduced blood flow to the brain, but the exact mechanism is unknown. A team of researchers recently conducted a study to determine whether or not increased inflammation of the brain, also known as neuroinflammation, is the main culprit.
The air pollutant secondary organic aerosol (SOA) forms when ammonia and amines react with oxygenated species. When ammonia is present when alkenes react with ozone, SOA increases in size and numbers. This may be due to Criegee intermediates. New research found that a particular amine, dimethylamine, reacts 34,000 times faster with one version of the Criegee intermediate acetaldehyde oxide than with another version of the same compound.

99% of the world’s population breathes air that exceeds the limits recommended by the World Health Organization (WHO). This scenario is exacerbated in urban areas where more than 50% of the world’s population is concentrated.
Air pollution and its high concentration in cities is one of the problems facing society today, due to its harmful effects on the environment, but also on human health. One of the causes of this pollution is the increase in nitrogen oxide emissions, mainly due to the use of fossil fuels.
Nitrogen dioxide is one of the criteria air pollutants that plays an important role as a precursor gas of fine particulate matter and ozone. NO2 emissions are known to be primarily generated by industrial facilities or vehicle exhausts.
