Answer 1

Answer:

yes

Explanation:

Answer 2

Answer:

In simple words gaseous pollutants are in the form of a gas in the atmosphere, e.g., nitrogen dioxide (NO2), sulphur dioxide (SO2), ground level ozone (O3), carbon monoxide (CO), VOCs etc, whereas particulate pollution which can also be called dust pollution or particulate matter are in the form of tiny particles. The size and composition of these particle vary. However the most dangerous for the human health are PM10 and PM2.5 (These are particle with aerodynamic diameter up to 10 micrometer and 2.5 micrometer, respectively). Fine and ultra-fine particles are mostly emitted by combustion processes, e.g., combustion process taking place in vehicle engines, whereas coarse particles are generated mostly by mechanical and physical processes, such as wear and tears of tyres, crushing machines, windblown dust and so onFor gaseous pollutants such as O3, NO2, and SO2, the site of deposition in the respiratory tract is largely a function of water solubility. For highly soluble gases, the nose serves an important defensive function because the air inhaled transnasally is passed over the large, irregular surface of the turbinates. The promotion of turbulent flow prolongs contact with the mucosal surface, increasing adsorption. Under conditions of quiet breathing, when most air is inspired transnasally, the concentration of SO2 that reaches the glottis is less than 2% of the concentration inspired at the nose
