Scrapping and pollution. Despite shipbreaking being a profitable industry there are a number of environmental and human health hazards. A brief review in numbers shows that scrapped ships have an unlabeled weight of between 5,000 and 40,000 tons, 95% of which is steel, coated with between 10 and 100 tons of paint containing lead, cadmium, organotins, arsenic, zinc and chromium. Ships also contain a wide range of other hazardous wastes, sealants containing PCBs, up to 7.5 tons of various types of asbestos and; several thousand liters of oil. Tankers additionally hold up to 1,000 cubic meters of residual oil. Most of these materials have been defined as hazardous waste. Bellow we try to give an idea of the severity of the problem by describing

Extensive human and mechanical activities accelerate the rate and amount of seashore erosion and results in higher turbidity of seawater.
Impact of shipbreaking on inter-tidal sediments and soils: Various refuse and disposable materials are discharged and spilled from scrapped ships and often get mixed with the sand. The scraps from the ships are staked on the sea shore, leaving behind an accumulation of metal fragments and rust in the soil.
Impact of shipbreaking on biodiversity: Coastal soil and sea water environment are mainly contaminated through the discharge of ammonia, burned oil spillage, floatable grease balls, metal rust (iron) and various other disposable refuse materials together with high turbidity of sea water. Furthermore, oil spilling may cause serious damage by reduction of light intensity, inhibiting the exchange of oxygen and carbon dioxide across the air-sea water interface, and by acute toxicity. As a result the growth and abundance of marine life may seriously be …show more content…
One of the most influential moves involved in this was the Hong Kong Convention for the Safe and Environmentally Sound Recycling of Ships 2009. The main aim of this was to lessen the dangers of ship dismantling. The convention turned the ‘green passport’ into an ‘inventory of hazardous materials’. Once the Hong Kong Convention is enforced all vessels, across the world, over the weight of 500GT will have to carry an inventory of hazardous materials (or green passport as it was previously known). According to this, ships will be required to have an initial survey to verify the inventory of hazardous materials, additional surveys during the life of the ship, and a final survey prior to recycling. Ship recyclers will also be required to detail the Ship Dismantling process to submit to the relevant authorities. The attached SHIP DISMANTLING PLAN is being used
