Answer 2

Answer:

Common air pollutants, such as ozone, sulfur dioxide, and nitrogen dioxide, have been shown to hit asthma sufferers particularly hard. But by irritating the airways and skin, air pollutants also make it easier for pollen grain to penetrate the human body.

Explanation:

Pollen counts normally rise during the morning, peak about midday, and then gradually fall. So the lowest pollen counts are usually before dawn, and in the late afternoon to early evening. pollen grains and other protein-containing particles in the air are altered by nitrogen oxides and ozone (nitration) in such a way that they are able to cause allergies more easily.
