PANAJI: TAR BALL DEPOSITION Recently on the beach Popular Goa tour – one of the worst to hit the coastline of the country – has indicated how the problem is slowly assuming a worry rate, something received by scientists.
Nearly 30 tons of muck was collected by the coastal cleaning agent appointed by the Government, Karnataka Industrial and Commercial Corporation Pvt Ltd (KCIC) from the coast in three Talukas.
Episode, massive and prolonged, playing almost two weeks.
Since Balls Tar first began spewing the coast of Goa in the 1970s, the scientists of the National Institute of Oceanography (NIO) had studied possible pollution sources.
In August 2010, April 2011 and May 2011, the Tar Ball deposition was very large on several beaches.
No oil spills reported in the Arabian Sea and NIO concluded that “the only source for tar ball formation can be agile spills / tankers from tankers who pass through the international tanker route throughout the Arab Sea.” In a study, using hydrodinamics and particle tracking models, Ball Tar particles were released numerically in eight locations on the sea and five of them reached the coast of Goa.
It showed a tanker washing and an unintentional oil spill along the international oil tanker route.
While the closest coastal areas on both sides of the Goa border also reported tar pollution balls, NIO studies have found depositions to contain biological communities such as diatoms, bryozoa, blue-green algae, and geose feathers, which mix with oil.
Other studies also found that tar ball formations could occur due to release from oil installations such as oil (BH) oil fields.
A stretch of 650 km west coast can be vulnerable to problems.
Scientists say that it becomes an international problem, the government must involve chemists, microbiologists, and coastal managers to develop management policies to overcome them.
