Air Pollution Affects Humans’ Life


Air pollution can cause a variety of illnesses in humans,

including asthma, lung cancer, heart disease and even

reproductive and developmental disorders. It can also

compromise the immune system by overworking the

respiratory system and the body's natural defenses. Air

pollution also contributes to global warming, increasing

worldwide temperatures, raising sea levels and damaging

agricultural yields.

Indoor air pollution can be particularly hazardous to

health as it is released in close proximity to people. It is

stated that a pollutant released indoors is many times

more likely to reach the lung than that released

outdoors. In the developing countries a fairly large

portion of the population is dependent on biomass for

their energy requirements.

These include wood, charcoal, agricultural residue, and

animal waste. Open fires used for cooking and heating

are commonly found in the household both in the rural

and the urban areas. The stove is often at floor level,

adding to the risk of accident and the hygiene factor. In

addition, they are often not fitted with a chimney to

remove the pollutants. In such households the children

and women are most likely to be affected, as they are

the group that spends more time indoors.

The main pollutant in this environment is the SPM. In

fact, death due to indoor air pollution, mainly particulate

matters, in the rural areas of India are one of the highest

in the world.

Many of the deaths are due to acute respiratory

infections in children; others are due to cardiovascular

diseases, lung cancer, and chronic respiratory diseases in

adults. If emissions are high and ventilation is poor,

household use of coal and biomass can severely affect

the indoor air quality.
