EFFECTS OF AIR POLLUTION ON HUMAN
What are the effects of air pollution on plants?
What are the effects of air pollution on MATERIALS?
- around 30-40% of cases of asthma and 20-30% of all respiratory disease.
- effect our health in many ways with both short term and long term effect.
- Short term effect are: irritation to nose, eye, throat, bronchitis, headache etc.
- Long term affect are: lung disease, chronic respiratory problem, damage to heart, brain, eyes etc.
- Eye irritation due to NOx, O3 , PAN, particulates.
- Nose and throat due to SO2 , NOx etc.
- Gaseous pollutants like H2S, SO2 , NO2 and hydrocarbons cause odor nuisance.
- Irritation of respiration tract caused by SOx, NOx, CO, O3 .
- Increase in mortality.
- High conc. of SO2 , NO2 and SPM causes bronchitis and asthma.
- CO and NO react with haemoglobin and reduce O2 carrying capacity of blood.
- Heavy metals like lead can cause poisoning. High conc. cause damage to liver and kidney.
What are the effects of air pollution on human health?
- Nature of the pollutants
- Concentration of the pollutants
- Duration of exposure
- State of health of receptor
- Age group of the receptor
What are the effects of air pollution on plants?
- Decrease yield in agriculture.
- Suppressed growth of vegetables.
- Leaf injury and damage to young plants.
- Decreased growth rate and increased death rate.
What are the effects of air pollution on MATERIALS?
- Corrosion of metals due to SO2 in presence of oxygen and moisture is converted into H2SO4 acid.
- H2SO4 acid react with limestone, marble and other building materials to cause deterioration.
- Soiling and eroding of building materials.
- SO2 , O3, H2S and aerosols damage protective coating and paints of the surface.
- O3 and PAN causes cracking of rubber and various electrical insulations.
- Deterioration of art work due to SPM.
