Hydration State of the Moss Hylocomium splendens and the Lichen Cladina stellaris Governs Uptake and Revolatilization of Airborne α- and γ-Hexachlorocyclohexane

Henrik Kylin and Henk Bouwman
pp 10982–10989

  • The partitioning of α- and γ-hexachlorocyclohexane between air and the moss Hylocomium splendens and the lichen Cladina stellaris were studied under laboratory conditions.

Co-Release of Hexabromocyclododecane (HBCD) and Nano- and Microparticles from Thermal Cutting of Polystyrene Foams

pp 10990–10996

  • Polystyrene foam is a very important insulation material, and hexabromocyclododecane (HBCD) is frequently used as its flame retardant. HBCD is persistent, bioaccumulative, and toxic, and therefore workplace exposure and environmental emission should be avoided. In this study, we investigated the co-release of HBCD and aerosol particles during the thermal cutting of expanded polystyrene foam (EPS) and extruded polystyrene foam (XPS).

Diastereoisomer- and Enantiomer-Specific Accumulation, Depuration, and Bioisomerization of Hexabromocyclododecanes in Zebrafish (Danio rerio)

Miaomiao Du, Lifeng Lin, Changzhou Yan, and Xian Zhang
pp 11040–11046

  • In this study, zebrafish (Danio rerio) were exposed to two dietary concentrations of individual HBCD diastereoisomers (α-, β-, and γ-HBCD) for 42 days, followed by clean food for 21 days, to examine bioaccumulation, depuration, and enantiomer fractions (EFs) of HBCD diastereoisomers and to test the bioisomerization of HBCDs in fish.

2,2′,3,5′,6-Pentachlorobiphenyl (PCB 95) and Its Hydroxylated Metabolites Are Enantiomerically Enriched in Female Mice

Izabela Kania-Korwel, Christopher D. Barnhart, Marianna Stamou, Kim M. Truong, Mohammed H. M. E. El-Komy, Pamela J. Lein, Peter Veng-Pedersen, and Hans-Joachim Lehmler
pp 11393–11401

  • This study measures levels and enantiomeric enrichment of PCB 95 and its hydroxylated metabolites (OH-PCBs) in adult female C57Bl/6 mice following subchronic exposure to racemic PCB 95.
