Introduction
What is Plasma?
Plasma is the fourth state of matter;
solid, liquid, gas and plasma.
Composition matter of universe
What is Atmospheric plasma?
It is easier to produce plasma in low pressure condition than atmospheric, but producing plasma in vacuum state needs many devices.
So, many researcher study that how to produce plasma in atmospheric condition.

Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2
SO2 + OH. HSO3.
