Global styrene oligomers monitoring as new chemical contamination from polystyrene plastic marine pollution

Ecotoxicity testing of microplastics: Considering the heterogeneity of physicochemical properties

“…The toxicological profiles of several monomers and additives used in the production of certain plastic types are well known. In addition, PS is of interest because its styrene oligomers are shown to leach into ambient water and sediments (Kwon et al 2015). 4) Polystyrene and its copolymers because, again, the monomer styrene is a suspected carcinogen (Rossi and Lent 2006;Lithner et al 2011).…”

Petroleum hydrocarbon release behavior study in oil-sediment aggregates: turbulence intensity and chemical dispersion effect

“…Turbulence was selected to be 120 rpm because this speed was most similar to real-world marine environments. 39,40 Also, at this turbulence level the release effect was higher than that of all dispersants, which helped to better explore the interaction between dispersants and turbulence. As showed in Fig.…”

Micro-and macro-plastics in marine species from Nordic waters

“…Monomers and polymers are the building blocks of plastics but they can also be released from plastics as they become brittle and break down in the environment. For example, styrene monomers, dimers and trimers have all be detected in seawater and sediments from coastal regions (Kwon et al, 2015). Additives are incorporated into plastics during plastic production although the quantities used vary greatly.…”
