Pollution of Marine Environment by Ship

Abstract

Many pollutants are released into the marine environment far upstream from coastlines. But there are various ways by which pollutants enters to the marine environment. Ships are one of the sources of these pollutants. There are two ways in which the seas are contaminated by ships. One of them is routine pollution the other are ship accidents that cause pollution in the seas. Routine contamination occurs when the wastewater such as bilge, ballast and sewage of vessels is discharged into the sea without resorting to international rules. Accidental pollution occurs by landing and collision of vessels carrying petroleum and other harmful cargo. The types of pollution that may originate from ships include oil, chemicals, garbage sewage, air pollution from the ship’s engines and bunker fuel and the anti-fouling paint on a ship’s hull. Marine pests in ship’s ballast water or clinging to the ship’s hull can also harm marine environments.
