Particulate pollution is pollution of an environment that consists of particles suspended in some medium. There are three primary forms: atmospheric particulate matter, [1] marine debris, [2] and space debris. [3] Some particles are released directly from a specific source, while others form in chemical reactions in the atmosphere.
The tiny pollutants emitted by fossil fuel combustion and wildfires may be raising the risk of adverse birth outcomes, a study has found. Exposure to fine particulate matter (PM 2.5) can cause ...
The January 2024 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 5,390 towns and cities in 63 countries. Air quality in the database is represented by the annual mean concentration of particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 micrometers, respectively). [1 ...
A study by the European Environment Agency estimates that 307,000 people have died prematurely in 2019 due to fine particle pollution in the 27 EU member states. [213] A study in 2000 conducted in the U.S. explored how fine particulate matter may be more harmful than coarse particulate matter. The study was based on six different cities.
The cause for concern is, "the main component of smoke is particulate matter and that can penetrate deep into the lungs, which directly causes respiratory issues but it can also enter the ...
By contrast, the same increase in exposure to fine particulate matter from other sources — like cars or factories — was linked to a 3% increase in the odds of getting dementia.
Particles from car tyres pollute the environment and the air we breathe, whilst the long-term effects on our health and the ecosystem are unknown. These tyre wear particles are especially damaging due to the toxic chemicals that they are made from, which leach out of the particles into our rivers and oceans.
Toxic "black carbon" air pollution particles inhaled during pregnancy have been found in the tissues and organs of fetuses, according to a new study. For 1st time, potentially toxic air pollution ...
