Chapter 34: Problem 3

What is the difference between primary and secondary pollutants? Give examples in each case.

Short Answer

Expert verified

Primary pollutants are directly released into the atmosphere, examples include soot and carbon monoxide. Secondary pollutants are formed when primary pollutants react with other components in the atmosphere, examples include smog and acid rain.

Step by step solution

Define Primary Pollutants

Primary pollutants are pollutants that are put directly into the air by human activity. For example, soot and carbon monoxide from vehicles and factories are considered primary pollutants.

Define Secondary Pollutants

Secondary pollutants are formed when primary pollutants react with each other or with various components in the atmosphere. Examples include smog and acid rain.

Comparison

Comparing the two, primary pollutants are directly emitted from sources, while secondary pollutants are formed from subsequent reactions involving primary pollutants in the atmosphere. Differentiating them helps to know their sources and understand how to control them.
