Saido, 1.6 - Ocean Contamination Generated from Plastics, In Comprehensive Water Quality and Purification, edited by Satinder Ahuja, Elsevier, Waltham, 2014, Pages 86-97, ISBN 9780123821836, http://dx.doi.org/10.1016/B978-0-12-382182-9.00005-0. (http://www.sciencedirect.com/science/article/pii/B9780123821829000050) Abstract: For clarification of causes leading to new global chemical contamination from plastics, beach sand and water taken from sites around the world were extracted with dichloromethane and analyzed by selected ion monitoring-gas chromatography/mass spectrometry (SIM-GC/MS). All samples were found to contain the styrene oligomer (SO) (in this study, SO is considered to be a mixture of styrene monomer (SM), )1styrene dimer (SD1), SD2, and styrene trimer (ST)), a mixture consisting of phenylethylene (SM), 2,4-diphenyl-1-butene (SD), and 2,4,6-triphenyl-1-hexene (ST). New global chemical contamination products were clearly shown to be derived from polystyrene (PS) decomposition and/or elution in the ocean, as well as from marine debris plastics whose presence may persist well into the future. Keywords: Adverse effects; Bisphenol A; Degradation; Elution; Marine debris plastics; Nonylphenol; Phthalate; Styrene oligomer; Toxicity

(http://www.sciencedirect.com/science/article/pii/S0960982213012530) Abstract: Summary Inadequate products, waste management, and policy are struggling to prevent plastic waste from infiltrating ecosystems [1 and 2]. Disintegration into smaller pieces means that the abundance of micrometer-sized plastic (microplastic) in habitats has increased [3] and outnumbers larger debris [2 and 4]. When ingested by animals, plastic provides a feasible pathway to transfer attached pollutants and additive chemicals into their tissues [5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15]. Despite positive correlations between concentrations of ingested plastic and pollutants in tissues of animals, few, if any, controlled experiments have examined whether ingested plastic transfers pollutants and additives to animals. We exposed lugworms (Arenicola marina) to sand with 5% microplastic that was presorbed with pollutants (nonylphenol and phenanthrene) and additive chemicals (Triclosan and PBDE-47). Microplastic transferred pollutants and additive chemicals into gut tissues of lugworms, causing some biological effects, although clean sand transferred larger concentrations of pollutants into their tissues. Uptake of nonylphenol from PVC or sand reduced the ability of coelomocytes to remove pathogenic bacteria by >60%. Uptake of Triclosan from PVC diminished the ability of worms to engineer sediments and caused mortality, each by >55%, while PVC alone made worms >30% more susceptible to oxidative stress. As global microplastic contamination accelerates, our findings indicate that large concentrations of microplastic and additives can harm ecophysiological functions performed by organisms. http://download.cell.com/current-biology/pdf/PIIS0960982213012530.
