Introduction
In general, contaminants are the waste substances deposited into the water source
or onto land which affects the soil, environment, and water sources. Contaminants
are of various forms such as liquid, solid, and gases. All the three forms of contam-
inants should be monitored and treated periodically. It is the prime duty of all the
industries to treat the waste appropriately before channeling into the environment.
Emerging contaminants (ECs) are the substances those cause no pollution when
deposited in minor quantities. The increased use of various products and disposal
of the same into the environment causes serious hazards. It is the prime duty of
biotechnologists to educate the society about the ECs and need of treatment for those
contaminants. ECs are unregulated and they are not included in the regular moni-
toring system for waste deposition and treatment. They include wide range of sub-
stances like personal care products (PCPs), pesticides, pharmaceuticals, plasticizers,
nourishment-added substances, wood additives, clothing cleansers, surfactants, dis-
infectants, fire retardants, etc. The ECs need to be monitored, analyzed, and treated
to protect the environment. Water is the major place for the deposition of the ECs.
Treatment of EC is one of the major step to protect the environment and water
sources in order to save the lives from the hazards. Various methods include chem-
ical, physicochemical, and biological for treatment of ECs. When compared to all,
biological approach is more efficient and harmless to environment.

Classification of Emerging Contaminants
ECs might be appearing in the environment from long ago, but appeared as
pollutants recently. They cause not only pollution in the environment but also affect
