Indoor Air Pollution
By FAIZAN SABIR
According to the latest World Health Organization (WHO) report, 8 million people die every year globally because of air pollution. Among these, 4.3 million die because of air pollution from household sources and 3.7 million die because of ambient air pollution. (WHO: Burden of disease from Household Air Pollution).
Indoor Air Pollution
A major threat to ecological system impacting public health
Despite the fact that pollution concentration fluctuates fundamentally from place to place, the dimensions of some regular air pollutants are more prominent inside than outside because the vast majority spend more time inside than outside. Risk of air pollution increased in the buildings with tighter insulation.
Various sources spreading indoor air pollution are tobacco smoke, carbon monoxide in air conditioners, concrete and different materials.
Sources of Indoor Air Pollution
Indoor air contamination has happened since ancient times when individuals used fire for cooking and heating inner spaces to live inside and now consuming of conventional solid fuels, for example, wood fuel, agricultural buildups, low quality air cooling systems and dried creature waste in ill vented cook-stoves in developing countries are the main causes of air pollution.
It has also been observed scientifically that the air inside homes and other open and places of business can be more genuinely contaminated than the outside air and ultimately indoor air pollution badly affects the public health.
Indoor Pollution Affecting Pakistan:
Lahore second worst in world air quality rankings.
“Since the last couple of years, the incidence of smog has grown at alarming levels, and the number of people coming in with respiratory issues has increased.” (Pakistan Today, NOVEMBER 29, 2018)
Indoor Air pollution also badly affecting Pakistan. According to a survey report, Pakistan ranks in the highest of childhood deaths due to pneumonia. Being a large contributor to pneumonia trouble, the nation has acute problems of indoor pollution. Biomass fuel (wood, crop buildups, creature waste) which is being utilized in four fifths of all family units in Pakistan for cooking, space warming and lighting homes is the real wellspring of indoor air pollution.
- In order to cope up the challenge of indoor air pollution, an integrated effort of public and private sectors is required.
- Research may be conducted in connection to various diseases caused due to indoor pollution especially tuberculosis and acute lower respiratory infections and a national level policy must be framed and implemented to combat indoor pollution and yielding promising result.
- Place indoor plants in office building and houses to clean the indoor air.
- Ban on smoking must be imposed on all public places and awareness to general public regarding effects of smoking must be enumerated.
- Public awareness campaigns with practical intervention would be helpful to avoid indoor pollution.
- Usage of improved quality of cooking stoves and modern fuels like natural gas and LPG may produce better results to evade indoor pollution.
