ABSTRACT: In the 21st century the fresh water scarcity increased very rapidly due to the urbanization
and industrialization process. In these conditions the urban wastewater plays
an important role in the water usage criteria. In this aspect, in all the major
cities, wastewater treatment plants have been constructed to treat the urban
wastewater in view of decreasing the water scarcity. The presence of nutrients
in the wastewater is considered as beneficial to agricultural practices. The
contaminants present in the wastewater pose health risks directly to
agricultural workers and indirectly to the consumers as the long term
application of the wastewater may result in the accumulation of toxic elements
in soil and in plants. In this way the heavy metals will circulate among the
food chain and food web to cause adverse effects on human health as well as on
soil health. In the present study an attempt has been made to study the
characteristics of urban wastewater at wastewater treatment plant of Mysore
city. And also heavy metal behavior was studied with the analysis of heavy
metals in wastewater, Biosolid and receiving soil along with the plants which
indicates the uptake of heavy metals.
