Question

Respiratory suspended particulate matter are particles having diameter gk today

Answer 1

Pollutants are the made up of soot, dust or smoke particles, which is measured by particular yard stick called as Respirable Suspended Particulate Matter (RSPM). The size of these pollutants is very tiny, which makes it virtually impossible to filter them out, which are less than 10 microns in diameter. RSPM is generally classified as PM10 (diameter 10-2.5 microns) and PM2.5 (under 2.5 microns). Source of pollutants: Source of these pollutants varies from organic to inorganic such as vehicular exhaust and stone-crushing and grinding, dust from construction and paved roads. Effect of RSPM on our body:The smaller PM2.5 affects the lungs and the air passage the most. The smaller the particles, the deeper they enter the lungs. Whereas the PM10 affects the upper respiratory tract from the nose and windpipe. Asthma and bronchial diseases are the result of RSPM which can worsens even further. It is most harmful for children, the pregnant women & elderly person. According to International research RSPM affects almost all organs, including the kidneys & brain and also contributes for lung cancer, abnormal foetal development in pregnant women.

Answer 2

Air pollution results from a variety of causes, not all of which are within human control. Dust storms in desert areas and smoke from forest fires and grass fires contribute to chemical and particulate pollution of the air. The source of pollution may be in one country but the impact of pollution may be felt elsewhere. These pigment enters the respiratory tract and clog the breathing system.
