Common Air Pollutents And Their Effects
Gasoues Pollution
(a) Oxide Of Carbon: These are Co2 and Co
(Co)Carbon Monoxide : Colerless/ odourless poisonous, power houses, burning of fossil fuels in houses/ industries, smoking, coul and wood.
CO² Carbon Dioxide = It is used by green plants for photosynthetic, co² contents of air has increased 15% in last 100 years due to burning of fuels.
Oxides of Nitrogen : No,No² it is used by green plants for photosynthetic,
It is released by chemicals industries/automobiles by burning of materials. No2 is produced by atmospheric nitrogen by electrical energy of lightning natural rediation.
Effects
No reduce oxygen carrying capacity of blood.
No² forms HNO³ with water vapour in air which is corrosive.
No² may cous irritation
Oxides of nitrogen cous damage to plants.
Oxide of Sulphur : So²,So³
Sources they are burning by burning of fossil fuels, thermal plants, moter vehicles, from h²s.
