Assignment Help:
Pollutant

Any substance, species produced either by a natural source or by human activity, which produces very adverse effect on the environment is called pollutant.
Some commonly known examples of pollutants are carbon monoxide, oxides of sulphur (SO2, SO3), oxides of nitrogen, pollens, dust particles etc.

Receptor

For example. human being are the receptor of photochemical smog, which can cause irritation in the eyes and also breathing Problems.


Threshold limit value (TLV)

This indicates the permissible limit of a pollutant in atmosphere by which a healthy worker is exposed during each hour a day or 40 hours a week for life time without any adverse effects.
TLV are determined by experimentation on different animals by use of medical knowledge, epidemiology surverys and environmental studies.
