\nPaper documents use of polyethylene sheets for detecting pollutants in water<\/p>\n


\n\tNARRAGANSETT, R.I. \u2013 March 11, 2008 \u2013 A paper published in 2007 by a 溏心vlog免费B站 researcher and colleagues at the Massachusetts Institute of Technology has been recognized by editors of Environmental Science and Technology as one of the \u201cbest of the best\u201d papers published that year.<\/p>\n


\n\tThe paper, \u201cPolyethylene Devices: Passive Samplers for Measuring Dissolved Hydrophobic Organic Compounds in Aquatic Environments,\u201d by Rachel Adams of MIT and Assistant Professor Rainer Lohmann at the 溏心vlog免费B站 Graduate School of Oceanography, was judged the year\u2019s second best in the environmental technology category. Only 10 of 1,200 papers were recognized. <\/p>\n


\nA summary of the winning papers will be published in the journal\u2019s April 1 edition.<\/p>\n


\nThe paper outlines how the researchers demonstrated the use of a polyethylene sheet — sold at most hardware stores for $1 as a painter\u2019s drop cloth \u2013 to detect contaminants like PCBs, dioxin, and oil components in water.<\/p>\n


\n\u201cThese compounds \u2013 called hydrophobic organic compounds \u2013 prefer to stay out of the water,\u201d explained Lohmann, who lives in North Kingstown. \u201cIf they had a choice between getting dissolved in water or becoming absorbed into plastic, they\u2019ll choose the plastic every time.\u201d<\/p>\n


\nSo Lohmann and his fellow researchers placed 3-by-10-inch sheets of polyethylene in several locations around Boston Harbor for two weeks. When the sheets were retrieved, they were analyzed in great depth to determine their absorption rates under varying conditions for a wide range of contaminants.<\/p>\n


\nAccording to Lohmann, this type of sampling device has been used before to detect pollutants, but never before had it been investigated in such detail using controlled laboratory experiments.<\/p>\n


\n\u201cOne of the beauties of this type of contaminant detection is that it makes the quantification of trace compounds in water easier and more precise than ever before,\u201d he said. \u201cAnd because it\u2019s inexpensive, you can look for contaminant sources at smaller scales than before. The novelty of our paper is that we validated that it works anywhere with almost any kind of hydrophobic organic compound.\u201d<\/p>\n


\nThe traditional system for detecting contaminants required that a large volume of water be filtered and solvents extracted, which is a laborious, time-consuming and expensive process.<\/p>\n


\nSubsequent to their use in the Boston Harbor tests, Lohmann has continued to use the polyethylene sheets to detect contaminants in Narragansett Bay, New Bedford Harbor, the Hudson River and at a Superfund site along the coast of Los Angeles. He is also consulting with other researchers using them in studies of pollutants in the Arctic.<\/div>\n","protected":false},"excerpt":{"rendered":"
