There exists a variety of sources of marine pollution, from that produced by the normal operation of ships, to the deliberate dumping of pollutants into the sea; within this contamination is a range of substances such as oil, noxious or hazardous substances, waste water or sewage, organic and inorganic wastes in atmospheric emissions. The International Maritime Organization (IMO), as a specialized agency of the United Nations has made efforts to produce legal instruments regulating different sources of marine pollution, giving life to the Marine Environment Protection Committee (MEPC), whose provisions are met and they are implemented through the Marine Environment Protection Department of the General Directorate of the Merchant Marine (GDMM).
