2) Industrial emission.

3) Transportation.

4) Open burning of garbage waste.

Answer 2

Explanation:

Air pollution is the world’s largest environmental risk to health,1 and a major cause of disease and premature death.2

Ambient (outdoor) and household (indoor) air pollution both contribute to the global burden. Emissions from transport, industry, power generation and agricultural processes affect both cities and rural areas and, according to estimates from the World Health Organization, 9 out of 10 of people worldwide breathe polluted air.2

Within the home, 3 billion people are at risk of household air pollution from use of unclean fuels and technologies for cooking and heating.3

Several common pollutants are harmful to health. However, ambient particulate matter ─ a complex mixture of solid and liquid particles suspended in air ─ is of particular concern, and levels of particulate matter are a key indicator of air quality and health risk.4

The respiratory system, as the first point of contact with inhaled pollutants, is uniquely vulnerable, but air pollution also affects the cardiovascular system and other aspects of health.5 Studies are continuing to identify causal associations of air pollutants with adverse health outcomes, and to uncover plausible biological mechanisms for these effects. The impact of air pollution on quality of life,6 and the effects of climate change on air pollution and health, are other important areas of study.

Here, The Clean Breathing Institute discusses the global burden of air pollution and the effects of air pollution on respiratory health.
