Question

This is non biodegradable pollutant
A) Sulphur dioxide
B) Oxides of nitrogen
C) Lead vapour
D) Sewage

Answer 1

Biodegradability is a term and mechanism that is relatively complex. It could be defined as the intrinsic ability of bacterial and micro-organic agents to decompose a substance..

Complete answer:
First we should know about non biodegradable pollutants to answer this question. A non-biodegradable material may be described as a category of product that cannot be broken down by organisms and serves as a source of contamination. Unlike biodegradable waste, it is not easy to treat non-biodegradable waste. Non-biodegradable traces are those that natural agents cannot decompose or dissolve.
Now, let us find the solution from the options-
Compounds that cannot be decomposed by microorganisms over a period of time in the atmosphere are non-biodegradable pollutants.
Batteries, ceramics, paints, and metal alloys are the usual products in which lead is present.
Poisonous fumes are emitted from lead materials, and are known as lead vapour.
Lead is known to be extremely toxic to human health. Microbes cannot destroy these compounds and therefore create pollution.

Thus, the correct answer is option (C) Lead vapour.

Note: Toxic pollutants that are not naturally degraded or decomposed into less destructive compounds are referred to as non-biodegradable pollutants. The main cause of creating non-biodegradable toxins is humans. Heavy metals like arsenic, lead and mercury, synthetic fabrics, polythene, and DDT are found among these contaminants.
