Visakhapatnam harbour
 
Description 487-497
Environmental parameters such as, temperature,
salinity, pH, dissolved oxygen (DO),
Biological Oxygen Demand (BOD) and nutrients (nitrite, phosphate and silicate)
were monitored at three stations (Slipway Complex, Ore Berth and Marine Foreman
Jetty) in the highly polluted Visakhapatnam
harbour from February 2007 to January 2009. Above parameters varied spatially
and temporally in the study region. 
Possible causes to such variations were explained.  Results from the study of environmental
factor were compared with past 30 years data. Pollution still exists in Visakhapatnam harbour with
an increasing gradient from Slipway Complex to Ore Berth to Marine Foreman
Jetty. Improvement in environmental parameters was noticed as evidenced from an
increase in pH and reduction of BOD
as well as eutrophication.
