Seasonal variation in organotins in the waters of the Dona Paula Bay, west coast of India.
Surface seawaters from the Dona Paula Bay, were collected at weekly intervals during March 2007 to March 2008, and analyzed for butyltins (BT) such as tributyltin (TBT), dibutyltin (DBT), monobutyltin (MBT) using a GC-MS system. The mean concentrations of TBT, DBT, MBT and total BT varied from <1-37, 4-19, 6-28 and 21-84 ng Sn L(-1), respectively. Highest levels of BTs were recorded during May followed by April 2007 and March 2007 probably because the shipping and tourism activities are very high during these months.
