Consider the following statements regarding various Tropospheric Pollutants.

1. Higher concentrations of NO2 damage the leaves of plants and retard the rate of photosynthesis.

2. Nitrogen dioxide, a lung irritant is harmful to living tissues as well as various textile fibres and metals.

3. High concentration of SO2 leads to stiffness of flower buds which eventually fall off from plants.

GASEOUS POLLUTANT

Gaseous Pollutants	Description	Impacts
Nitrogen oxide (NOx)	Various oxides of Nitrogen come under NOX. Caused due to the reaction between oxygen and nitrogen at high temps such as in combustion engines and industries.	Aggravates Ashtamatic conditions and other respiratory issues in humans. Plays a major role in the formation of SMOG, acid rain (nitric acid), and the greenhouse effect. Higher concentrations of NO2 damage the leaves of plants and retard the rate of photosynthesis
Sulphur dioxide (SO2	Pungent smelling colorless gas produced from mostly volcanic activities, industrial processes, and production of sulphuric acid	Respiratory issues, premature deaths, and death of certain nerves when inhaled. High concentration of SO2 leads to stiffness of flower buds which eventually fall off from plants.
