Which of the following statements about photochemical smog is wrong ?

Options

A. It has high concentration of oxidising agents
B. It has low concentration of oxidising agent
C. It can be controlled by controlling the release of `NO_(2)` hydrocarbons, ozone etc.
D. Plantation of some plants like pinus helps in controlling photochemical smog

Answer

B

Explanation

Photochemical smog or Los Angles smog was first observed in Los Angles in 1950. It is formed due to photochemical reactions taking place when air contain `NO_(2)` and hydrocarbons.
The concentrations of `O_(3)`, PAN, RCHO and `R_(2)CO` builds up in the atmosphere. These compounds produce irritation in the eyes. Photochemical smog has high concentration of oxidants such as `O_(3)` organic oxidant etc.
