Stack emission limit as per CPCB India

Hi everyone..

As per CPCB, Ambient Air Quality Standards in India should be as follows;

Sulphur Dioxide (SO₂), µg/m³	Annual* 24 hours**	50 80	20 80
Nitrogen Dioxide (NO₂), µg/m³	Annual* 24 hours**	40 80	30 80
Particulate Matter (size less than 10 µm) or PM₁₀ µg/m³	Annual* 24 hours**	60 100	60 100
Particulate Matter (size less than 2.5 µm) or PM_2.5 µg/m³	Annual* 24 hours**	40 60	40 60
Ozone (O₃) µg/m³	8 hours* 1 hour**	100 180	100 180
Lead (Pb) µg/m³	Annual* 24 hours**	0.50 1.0	0.50 1.0
Carbon Monoxide (CO) mg/m³	8 hours* 1 hour**	02 04	02 04
Ammonia (NH₃) µg/m³	Annual* 24 hours**	100 400	100 400
Benzene (C₆H₆) µg/m³	Annual*	5	5
Benzo(a)Pyrene (BaP)- particulate phase only, ng/m³	Annual*	1	1
Arsenic(As), ng/m³	Annual*	6	60
Nickel (Ni), ng/m³	Annual*	20	20

This is for ambient air quality limit for different pollutants.

Suppose if a stack is emitting pollutants, what will be the maximum amount, they can emit?

Is there any standard limit for stack emission level for different pollutants?

Can anyone please help me..
