University of Benin Department of Animal and Environmental Biology Postgraduate Seminar on Environmental Impacts of Polyethylene Products Presented by Ogbemudia Osamuyi Godfrey PGD-Natural Resource Management 23rd of May, 2014 Introduction • Polyethylene(PE) is a thermoplastic polymer gotten through the polymerization of ethylene monomer to form long chain hydrocarbon compound. the hazard is not greatly different from that associated with any combustion of organic materials. The melt temperature of polypropylene can be anywhere between 200oC (392oF) to 250oC (482oF), although it can go higher depending on the grade of polypropylene and the kind of additives it contains. Polypropylene can be manufactured to a high degree of purity to be used for the semiconductor industry. Polypropylene is widely regarded as one of the most versatile plastics. Slovak AJ. The U.S. Food and Drug Administration (FDA) considers polystyrene safe, as long as it contains less than one percent styrene.

It is one of the most commonly produced plastics worldwide, with tens of millions of tons produced every year. The current global demand for polypropylene creates an annual market of around 45 million metric tons; estimates show that the demand will increase to approximately 62 million metric tons by 2020. Global Environmental Change Part B: Environmental Hazards (1999 - 2006) Browse the list of issues and latest articles from Environmental Hazards. But for the rest of your things, like household items or automotive parts, try to find a non-plastic alternative so that your health will not be at risk. Polypropylene Polybutene (published in 1982), polyethylene (published in 2007), polyisobutene (published in 2008), and hydrogenated polyisobutene (published in 2008) have previously been reviewed by the CIR Expert Panel, which concluded that these ingredients are safe as cosmetic ingredients in the practices of use and concentration as Occupational hazards of polyethylene and polypropylene manufacture. Household appliances and automotive industries both consume 10 percent each and construction materials is close behind with five percent. It can cause genetic mutations and tumors. Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. h޴�]��(�� Find high quality Polypropylene Hazards Suppliers on Alibaba. Polyurethanes, polyacrylonitrile, PVC, epoxy and styrenic copolymers ranked as most hazardous. Polypropylene plastics break down when they are exposed to high temperatures that are typical of the manufacturing process, especially when they are presented with a common mineral filler called talc. It is stable (does not decompose) in landfills or in aquatic systems. The United States Department of Transportation (USDOT) and the United Nations (UN) Model regulations consider polypropylene polymers to be non-hazardous. Household appliances and automotive industries both consume 10 percent each and construction materials is close behind with five percent. But for the rest of your things, like household items or automotive parts, try to find a non-plastic alternative so that your health will not be at risk. In terms of risk, styrene exposure is mainly an occupational hazard for workers producing polystyrene. environmental impacts of polyethylene generation and disposal in Benin City, Nigeria. Polypropylene is bad for the endocrine and reproductive systems. These gases are, in many cases, hazardous to human health. 55 plastic polymers were ranked based on monomer classifications, and assessed. There are 31 OEM, 31 ODM, 11 Self Patent. Leaching tests, toxicity tests and Toxicity Identification Evaluations (TIEs) were made on plastic products [I, II], synthetic textiles [III], and discarded electronic products [IV]. Polypropylene is blow-molded into bottles for foods, shampoos, and other household liquids. 73 0 obj <>/Filter/FlateDecode/ID[<6DA801F2A374C9129DEE6BF5882E0251><17826159C174F741814592FF2399CB94>]/Index[66 22]/Info 65 0 R/Length 57/Prev 93015/Root 67 0 R/Size 88/Type/XRef/W[1 2 1]>>stream Prog Clin Biol Res. Polythene pollution has drastically disturbed everyman’s life style. When heated polypropylene will become very sticky and will burn. What we need on additives, and this is for all plastics, is to: Know the additives used in plastics The hazards they poseAnd plans to move away from the … A hazard ranking model was Environmental Hazards (2007 - current) Formerly known as. Disposable masks contain polypropylene – a form of plastic – and therefore it could be the next biggest environmental hazard. It can mimic the. Classification System § This material is not hazardous by OHSA hazard communication definition. Polystyrene, the material with which most of the population has experience, contains only low levels of styrene. It can mimic the female hormone estrogen, therefore causing an overload of it in the woman’s body, which causes problems with fertility and conceiving. Its resistance to bacterial growth makes it suitable to be used in medical equipment. %PDF-1.5 %���� PMID: 6718381 [PubMed - indexed for MEDLINE] Are Plastic Water Bottles Safe for Regular Home Use? h�b```f``�e`b`� d�e@ ^0�h8��]�����I��]E�4���]:M�M$��d �aR�iR��PD@"�A�����A�1L y�/=@����"��Q|/�f�Rt�r9�v�n�� POLYPROPYLENE reacts with chlorine, fuming nitric acid and other strong oxidizing agents. Polyethylene is a thermoplastic polymer that has a variable crystalline structure.
