Air pollution effects on plants are mostly found on leaves?
Answers
yes it is because in the leaves the stomata pores are present and it attaches the dirt with it that's why it happens
Answer:Yes
Explanation:
Pollution from car exhaust, factory emissions, fuel combustion and other sources can hang a brown cloud over some cities. Air pollution not only contributes to respiratory diseases in humans and damages buildings, it can also affect plants. The effects of air pollution on plants develop over time and can't be undone. Some plants are more susceptible to pollution damage than others according to Fred Davis, a chemist from Kent State University.

Leaf Damage
Chemicals such as sulfur dioxide, ozone, fluorides and peroxyacyl nitrate damage the leaves of plants. If enough leaves are damaged, the entire plant will die. Sulfur dioxide, a by-product of burning fossil fuels such as oil, coal and gasoline, causes changes in the colors of leaf tissue, which may turn white, brown or yellow.
Some sulfur dioxide converts to sulfuric acid, which eats holes in the leaves. Ozone damage on leaves appears as mottled spots, which may be yellow, black or brown. If the damage by ozone is severe enough, the plant will drop its leaves altogether. Fluoride damages the edges of plants and causes them to turn brown or black. Peroxyacyl nitrate causes a condition known as silver leaf, in which the underside of the leaves turn silvery white or bronze.
