Year: 2014 Language: english Author: Mukesh Doble, Ramasamy Venkatesan, Nelamane Vijaya, Ravi Kumar Publisher: Smithers Information Ltd Edition: 1st ISBN: 978-1-84735-575-1 Format: PDF Quality: eBook Pages count: 256 Description: Plastics are synthetic organic polymers that are produced worldwide at a rate of 100 million tons per year and have replaced several construction, automobile and engineering materials, because of their advantages, ease of fabrication, and cost. Plastics and composites which include polyester, polyethylenes, fluorinated hydrocarbons, foams, urethanes, carbon fibre reinforced plastic and glass fibre reinforced plastic and so on, are also used in marine applications as hulls, fenders, insulating materials, pipelines and so on. The increased consumption over time has led to escalating levels of them as waste in the land and in the ocean. The waste from the land reaches marine waters via industrial discharge, littering beaches and runoff. Most polymers are highly persistent in the marine environment and those that float degrade slowly via photocatalysis using ultraviolet (UV) radiation. Plastics that sink remain persistent for very long periods of time. Approximately 80% of plastic pollution in the sea originates from the land, and the rest is produced from recreational sailors, commercial operations, maritime industries, and the military.
