Question

why is the air in the troposphere being polluted?​

Answer 1

♣️ here's your answer ♣️

▶️But in the troposphere, near ground-level, ozone molecules are both air pollutants, threatening the health of living things, and greenhouse gases, trapping heat and contributing to climate change. A small amount of ozone does occur naturally at ground level. Plants and soil release some.◀️

hope it helps you

thanks ☺️

☘☆The Troposphere Being Polluted By The  air pollutants, threatening the health of living things, and greenhouse gases, trapping heat and contributing to climate change.

Explanation:

☘☆Tropospheric air pollution has impacts on scales ranging from local to global. Reactive intermediates in the oxidation of mixtures of volatile organic compounds (VOCs) and oxides of nitrogen (NOx) play central roles: the hydroxyl radical (OH), during the day; the nitrate radical (NO3), at night; and ozone (O3), which contributes during the day and night. Halogen atoms can also play a role during the day. Here the implications of the complex VOC-NOx chemistry for O3 control are discussed. In addition, OH, NO3, and O3are shown to play a central role in the formation and fate of airborne toxic chemicals, mutagenic polycyclic aromatic hydrocarbons, and fine particles.
