SOIL CONTAMINATION AND REMEDIATION EFFECTS ON T...

Soil can be defined as the space time continuum forming the upper part of the earth's crust. It
is a natural body comprised of solid  liquid and gases that occur on the land surface. Joffe
(1949) defined soil as a natural body differentiated into horizons of mineral and organic
constituents usually unconsolidated of variable depth  which differs from the parent material
below in morphology  physical properties and constitution  chemical properties and composition
and biological characteristics. Soil is one of the most fundamental resources for
sustainability and survival. It is one of the most important assets to protect and pass on to
future generations. Soil contamination due to anthropogenic and natural sources is increasing
day by day because of increasing population  industrialization  and urbanization. Soil is the
receptor of many contaminants from various sources. Contamination decreases the quality of the
soil and adversely affects soil organisms. For this study  soil samples from thirteen locations
contaminated from agricultural  industrial  and organic sources spread over the districts of
Alappuzha and Kottayam in Kerala in the south west coast area of India were analyzed to study
the changes in soil characteristics and its influence on soil microbial communities and their
activities.
