Panaji: Goa MP Shantaram Naik has requested the Centre to send a team of experts to examine the surfacing of tar balls on several beaches in the coastal state.
Terming the phenomenon as a `nuisance`, Naik, in a letter to Union Environment and Forest Minister Jairam Ramesh, said a proper study needs to be conducted to decipher the exact cause behind the presence of black thick tar balls on the beaches.

The state government has sought the help of experts from National Institute of Oceanography (NIO) to examine tar balls so that their source could be traced.

The Congress MP insisted that there must be an international convention to regulate such behaviour.
