Effects of particulate matter

Effects of particulate matter First among the effects - , the health consequences are always mentioned. When we breathe in about 15,000 litres of air a day, we unintentionally inhale many thousands of dust particles.

The smaller the particles, the more serious the damage to health - do my homework club . Particles up to 10 µm in size stick to the mucous membranes in the nasopharynx. Smaller dust particles can reach the lungs via the larynx and settle in the alveoli. There they cause inflammation, asthmatic complaints and probably cancer. The smallest particles with a diameter of 0.1 µm even reach the bloodstream via the lungs and from there into other internal organs. Possible consequences are thromboses, cardiac arrhythmias or even heart attacks. Less suitable for front pages, but not entirely unimportant, are the climatic consequences caused by large dust clouds in the atmosphere, which, however, do not only consist of PM10.

Volcanic eruptions, large forest fires or industrial plants release huge amounts of dust. Water molecules in the air attach themselves to the particles - , so that large-scale aerosols or clouds form in the atmosphere. These absorb the solar radiation falling on the earth and thus lead to a - locally limited - cooling.
