INTRODUCTION • Oil Spill: Release of large amount of oil into a water body leading to disastrous environmental effects. • Oil spills can occur due to various reasons such as – Equipment breakdown in an oil tanker which causes leakage of oil into the sea – When countries are at war, one country may decide to dump gallons of oil into the other country’s oceans. – Illegal dumping of crude and waste oil into ocean – Natural disasters (like hurricanes) may cause an oil spill, too by causing an oil tanker to flip over, pouring oil out. 10 th NOS-DCP Meeting 2 Prof. Manju Mohan CAS, IIT Delhi
