Foreword
Environmental
surveillance is an essential pre-requisite for pollution control.
The Central Pollution Control Board (CPCB) carries out periodic monitoring
in surface waters, ambient air, coastal waters, besides noise, groundwater
and bio- monitoring. CPCB also monitors environmental impacts and
episodal pollution caused by accidental discharge of pollutants from
different sources including oil spills. Cases of oil spills arising
out of ships getting wrecked in the high seas have been on the rise
around the world and this has drawn flak from the environmentalists
due to the extensive damage caused to the marine fauna.
The Zonal Office, Calcutta under the supervision of Dr. R. N. Bhattacharyya
conducted a survey from June 21-27, 1997 following a Korean cargo
ship "M.S. Green Opal" carrying steel sinking on 19th June 1997.near

Jetty in the inter-tidal zone of river Hugli. The sediment and water
samples collected at that time do confirm that the aquatic fauna was
effected.
This report is dedicated to the memory of Prof Amiya Kumar Chakraburtty
who passed away on December 17; 1997. Prof Chakraburtty took keen
interest in the activities of CPCB and he was always available to
offer useful guidance in analytical methods for pollution monitoring.
We hope, this report will serve as a reference document to all concerned
with monitoring and control of pollution in marine environment.
