Question

What do you understand by the term polluted air?

Answer 1

Hint: We need to understand air pollution and also the term polluted air. The presence of chemicals in the atmosphere that are hazardous to human and other living beings' health or damage the climate or materials is called air pollution. Many pollution-related illnesses, including respiratory infections, heart disease, COPD, stroke, and lung cancer, are all linked to air pollution.

Complete answer:
Gases (such as ammonia, carbon monoxide, sulphur dioxide, nitrous oxides, methane, and chlorofluorocarbons), particles (both organic and inorganic), and living molecules are all examples of air pollution.” Polluted air is defined as air that includes hazardous or unwanted chemicals that are produced by human or natural processes and whose concentration interferes with human health or is damaging to plants or animals.”
An air pollutant is a substance in the atmosphere that can harm humans and the environment. Solid particles, liquid droplets, or gases can all be used as the material. Pollutants can be either natural or man-made. Pollutants are divided into two categories: primary and secondary. Primary pollutants are generally created by natural processes, such as volcanic ash. Carbon monoxide gas from automobile exhaust or Sulfur Dioxide produced from industries are two more examples. Secondary pollutants are not directly released. Rather, they originate in the air as a result of the reaction or interaction of primary pollutants. A common example of a secondary pollutant is ground-level ozone.

Note:
Note that air pollution may cause illnesses, allergies, and even death in people; it can also harm other living species, including animals and food crops, as well as impact the natural environment (such as climate change, ozone depletion, and habitat destruction) and the built environment (for example, acid rain). Both human activities and natural causes may cause air pollution.
