Two types of pollutants are:
Natural pollutants:Natural pollutants include mist, dust, fumes.
Manmade pollutants: smoke particles, as well as smog pesticides, heavy metals, radioactive elements etc.
Fine particles of dust can enter the respiratory passage, potentially causing harm to delicate lung tissues. Dust pollution can result from activities like construction, building demolition, and traffic. Additionally, natural events such as wind and volcanic eruptions can also release dust into the environment.
The most harmful forms of particulate air pollutants, namely smoke and smog, can lead to various respiratory issues such as emphysema and asthma.
