ABSTRACT: The two major sources which are
contributing to marine pollution are natural processes as well as anthropogenic
activities. The natural process includes precipitation, erosion, weathering of
crystal material whereas anthropogenic activities are urbanization,
industrialization, mining and agricultural activities, etc. Mahanadi is the biggest river
source of Odisha which joins the Bay of Bengal at Paradip. Paradip Township is
an urbanized well-developed
industrial township where various anthropogenic activities are contributing
pollution to the water sources. In the present study, an attempt has been made
to estimate and monitor the seasonal and spatial variation of physiochemical
properties of the Mahanadi estuary, the East Coast coastal belt of India. The
result revealed that there is a remarkable variation in the physiochemical
parameters such as pH,
salinity, TSS, DO, BOD, NO2N, NO3N, NH4N, TN,
TP, SIO4 and Chl-a which are attributed to the runoff water getting
discharged to the coastal water sources. It is being recommended to treat waste
water and materials before discharging them to the marine water medium.
