DOI: 10.1002/etc.5356
Abstract: We evaluated the precision and accuracy of multilaboratory measurements for determining freely dissolved concentrations (Cfree) of polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in sediment porewater using polydimethylsiloxane (PDMS) and low‐density polyethylene (LDPE) polymeric… read more here.

DOI: 10.1007/s00204-019-02498-3
Abstract: Improved understanding of chemical exposure in in vitro bioassays is required for quantitative in vitro–in vivo extrapolation (QIVIVE). In this study, we quantified freely dissolved concentrations in medium sampled from in vitro cell-based bioassays (Cfree,medium) for… read more here.

DOI: 10.1021/acs.chemrestox.1c00037
Abstract: Discussions are ongoing on which dose metric should be used for quantitative in vitro-to-in vivo extrapolation (QIVIVE) of in vitro bioassay data. The nominal concentration of the test chemicals is most commonly used and easily… read more here.

DOI: 10.1021/acs.est.9b01088
Abstract: While microbial dechlorination of polychlorinated biphenyls (PCBs) has been observed in sediments over the last 3 decades, translation to the field has been difficult due to a lack of a clear understanding of the kinetic… read more here.
