TL;DR: Although the concentrations ofPBDFs found in the plastic matrices tested were 1 to 4 orders of magnitude lower than those of PBDEs, more attention should be paid to the fact that PBDFs are formed by sunlight exposure during normal use as well as disposal/recycling processes of flame-retarded consumer products.

TL;DR: In this paper, the presence of several organic substances in landfill leachates in Japan was investigated and approximately 190 compounds were detected using several analytical methods, including organic phosphates and phthalates, which originate from plastic additives.

TL;DR: The results suggest the use of alternative BFRs such as newly developed formulations derived from tribromophenol, tetrabromobisphenol A, or both as alternative flame retardants, because they contain triphenylphosphate as an impurity.

TL;DR: This is the first study to confirm photodegradation of PFOS in water and alkaline 2-propanol, and it was much faster and effective than in water.

TL;DR: Concentrations and congener compositions of poly chlorinated naphthalenes (PCNs), coplanar polychlorinated biphenyls (Co-PCBs), polychlorinate dibenzo-p-dioxins (PCDDs), and dibenzofurans (PCDFs) were determined in seven Halowax (HW) preparations.
