What pollutes the air in the city?

The sources of air pollution are intrinsically linked to how we live in cities. While many people see cars and transport as the most obvious causes of air pollution, nearly 70% of particulate matter is related to the built environment such as heating of buildings, construction and traffic related to it.

What pollute the air the most?

Burning Fossil Fuels

The biggest contributors of air pollution are from industry sources and power plants to generate power, as well as fossil fuel motor vehicles. The continuous burning of fossil fuels releases air pollutants, emissions and chemicals into the air and atmosphere.

Which of these is a metal air pollutant?

The heavy metals cadmium, lead and mercury are common air pollutants, be- ing emitted mainly as a result of various industrial activities. Although the at- mospheric levels are low, they contribute to the deposition and build-up in soils.

What is heavy metals pollution?

Heavy metals normally occur in nature and are essential to life but can become toxic through accumulation in organisms. Arsenic, cadmium, chromium, copper, nickel, lead and mercury are the most common heavy metals which can pollute the environment.

How do heavy metals cause air pollution?

The ecosystem is being ruined to the fact that the heavy metals are entering the food chain. Heavy metals also affect the biodegradability of organic pollutants, making them less degradable and thus causing double the effect of polluting the environment.

Is zinc a heavy metal?

Zinc is an essential heavy metal in the human body, and its homeostasis reflects a balance between absorption of dietary zinc and loss of zinc from the body (32). Zinc is required for the functional integrity of many organ systems, as well as for growth, development, and tissue repair (32, 45).
