MUMBAI: The city’s worst oil spill that destroyed swathes of mangroves last year left its indelible imprint on the ecology, irreversibly damaging the soil, researchers at the National Environmental Engineering Research Institute (NEERI) said in a study.

The collision of Panamanian vessels MSC Chitra and MV Khalijia 3 off the Mumbai coast on August 7, 2010, poured more than 800 tons of oil into the sea, 400 tons of it in the first few hours as the Chitra tilted to about 80 degrees. The ship was loaded with an estimated 2,600 tons of oil at the time of the accident.

Over 8.57 lakh mangroves along the coastlines of Mumbai, Thane and Raigad districts were severely affected by the crude due to tidal movements, damaging more than 6.27 lakh of the Avicennia Marina species and 2.30 lakh of the Sonneratia Alba species, the report says. Worst-hit was Navy Nagar, where 72% of A. Marina trees and 67% S. Alba trees were damaged. “The productivity of the mangroves was affected. They cannot generate leaves for oxygen transfer. The degradation of the quality of plant life and the water in turn adversely affects the insects and animals that thrive on it,” said a NEERI researcher…….
