Chemical composition and ecotoxicity of plastic and car tire rubber leachates to aquatic organisms

Water Research, Journal Year: 2019, Volume and Issue: 169, P. 115270 - 115270

Published: Nov. 6, 2019

Synthetic polymer-based materials are ubiquitous in aquatic environments, where weathering processes lead to their progressive fragmentation and the leaching of additive chemicals. The current study assessed chemical content freshwater marine leachates produced from car tire rubber (CTR), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS) polyvinyl chloride (PVC) microplastics, adverse effects on microalgae Raphidocelis subcapitata (freshwater) Skeletonema costatum (marine) Mediterranean mussel Mytilus galloprovincialis. A combination non-target target analysis revealed a number organic metal compounds leachates, including representing plasticizers, antioxidants, antimicrobials, lubricants, vulcanizers. CTR PVC corresponding had highest tentatively identified additives, while PET lowest. varied both between polymer seawater. Notable additives high concentrations were benzothiazole phthalide (PVC), acetophenone cobalt (CTR, PET), zinc PVC), (PP) antimony (PET). All except PET, inhibited algal growth with EC50 values ranging 0.5% (CTR) 64% total leachate concentration. Leachates also affected endpoints, lysosomal membrane stability early stages endpoints as gamete fertilization, embryonic development larvae motility survival. Embryonic was most sensitive parameter mussels, 0.8% 65% (PET) leachate. lowest impacts induced D-shell survival, reflecting ability down-regulate filtration presence stressors. This provides evidence relationship composition toxicity plastic/rubber leachates. Consistent increasing contamination by inorganic ranged slightly highly toxic mussels algae, highlighting need for better understanding overall impact plastic-associated chemicals ecosystems.

Microplastics as Both a Sink and a Source of Bisphenol A in the Marine Environment

Environmental Science & Technology, Journal Year: 2019, Volume and Issue: 53(17), P. 10188 - 10196

Published: Aug. 8, 2019

Microplastics were demonstrated to be an environmental sink for hydrophobic organic pollutants, while they can also serve as a potential source of such pollutants. In this study, the sorption and release bisphenol A in marine water investigated through laboratory experiments. Sorption desorption isotherms developed, results reveal that depend on crystallinity, elasticity, hydrophobicity polymer concerned. The adsorption partition quantified using dual-mode model mechanisms. Polyamide polyurethane found exhibit highest capacity A, it was almost irreversible, probably due hydrogen bonding. Polyethylenes polypropylene exhibited high reversible without noticeable hysteresis. Glassy polystyrene, poly(vinyl chloride), poly(methyl methacrylate), poly(ethylene terephthalate) low only partial reversibility. Low-density polyethylene polycarbonate microplastic particles first time proved persistent releasing into aquatic environments. Salinity, pH, coexisting estrogens, chemistry influence sorption/desorption behaviors different degrees. Plastic transportation vectors which may constitute ecological risk.
