Dandruff in Air Pollution

Research studies show humans and animals contribute as much to air pollution as automobile exhaust and industrial smoke do. Fur, pollens, cell fragments, skin particles, spores, bacteria, protein crystals and fungi shed by humans, animals and plants are present widely in aerosols in the atmosphere, according to the Institute for Atmospheric Physics at Mainz University, Germany.

Samples of air over a period of 15 years, found that biological matter constituted almost as much as 40 per cent of all aerosols in some areas and around 25 per cent in others.

Aerosols are involved in climate regulation, by warming the atmosphere by absorbing heat and cooling it by reflecting sunlight. This research can help climate scientists to study the effects of air pollution on climate and can also provide keys to certain health problems related to certain geographical regions.
Concentration of pollens was higher in spring, while the presence of cellular material was higher during winter and fall.

Scientists are being urged to take the role of bio-aerosols seriously in health and climate research.
