What is a degradable pollutant?
A degradable pollutant degrades after some time, either automatically (e.g., heat) or through the agency of microorganisms (e.g., domestic sewage, livestock wastes, market garbage). Biodegradable pollutants are easily disposed off or degraded through natural processes.
What are the non-biodegradable pollutants?

What are the two classes of degradable pollutants?
a) Bio-Degradable Pollutants- the pollutants which are decomposed by natural processes eg domestic (municipal) sewage. b) Non Bio-degradable Pollutants- The pollutants which don’t decompose naturally or decompose slowly eg.
