Answer:
The chemicals responsible for the pollution include carbon, sulfur, and nitrogen oxides.
Plants usually show damage in a variety of ways, including visible signs of damage like necrotic lesions, stunted plant growth, or changing in color including chlorosis (aka yellowing leaves), reddening, bronzing, mottling.
Ozone holes in the atmosphere also harm plants. Holes in the upper atmosphere allow an excess ultraviolet light to pass through the atmosphere leading to plant damage. In the lower atmosphere, ozone damages plants by preventing photosynthesis and obstructing stomata, restricting respiration and stunting plant growth.
Stratospheric ozone (O3) is produced by the combination of an oxygen atom (O) with an oxygen molecule (O2). The basic steps to formation are
oxygen atoms are represented as dark blue circles. This reaction is written in chemical equations as
O2 + UV => O + O
2 O + 2 O2 + third molecule => 2 O3 + third molecule
Net Reaction: 3 O2 + UV => 2 O3
UV radiation is also involved in the destruction of O3.
This destruction is expressed as
O3 + UV => O + O2
O + O3 => 2 O2
