Explain the effects of gaseous pollutants

Effects of gases Pollution:

• Carbon dioxide cause global warming because it is a potent greenhouse gas.
• Smog: Smog is a mixture of smoke and fog. Smog reduces visibility, and thus can create problems for drivers at highways. Pilots face problems while landing or taking off; due to smog.
• Carbon monoxide is a poisonous gas even at low concentration. It reduces oxygen carrying capacity of blood, and a person may die on exposure to carbon monoxide.
• Acid Rain: Oxides of sulphur and nitrogen mix with rainwater to create acid rain. Acid rain can be harmful for living beings and also for non-living things. Acid rain corrodes the outer surface of buildings. This has caused the Taj Mahal becoming pale.
• Suspended Particulate Matter in air can cause respiratory problems; like asthma and other respiratory disease.
• Greenhouse Effect: Greenhouse gases; like carbon dioxide and methane trap solar radiation and thus increase atmospheric temperature. This is called greenhouse effect.
• Global Warming: Overall increase in temperature of earth is called global warming.
