Question

Differentiate between the primary and secondary pollutants. Explain how these pollutants
are harmful for humans and environment in about 250 words.​

Answer 1

Answer:

Primary pollutants are emitted from natural or anthropogenic sources directly into the atmosphere, while secondary pollutants result from the chemical reactions or the physical interactions between the primary pollutants themselves .

Primary pollutants and secondary pollutants can be more dangerous. The first are those that are emitted directly from a source, which can be natural or of anthropogenic origin (carbon monoxide from vehicles). Secondary pollutants, on the other hand, are not emitted directly.

Primary pollutants, the beginning of the chain

Primary pollutants are the beginning chain of Carbon monoxide (CO), the result of the incomplete combustion of organic matter, which is why one of the main sources of emission is the associated traffic and the burning of fossil fuels. It is a flammable gas that is toxic to people even in small concentrations.

Secondary pollutants form due to mixing of primary pollutants and natural resources such as water, air etc. They are harmful like mixing of sulphuric acid susoended in air with rain to form acid rain . This rain causes skin deseases like skin cancer.
