Hi Arshad 

When you mention Pollution Department of India I assume you are talking about Central Pollution Control Board (CPCB).

There are a number of positions available at the CPCB like Junior Engineer in various fields like civil , Mechanical,etc., Scientist positions, Assistant Law Officer, Division Clerks , Technicians, etc.

All these posts have different requirements.

But all of them require the candidates to complete class 12 , bachelor degree or masters degree in their relevant fields.

Hope this helps.
