Concerns about the estrogenic properties of Bisphenol A (BPA) have led to increased efforts to find BPA replacements. 1,7-bis(4-Hydroxyphenylthio)-3,5-dioxaheptane (DD-70) and 4,4′-(hexafluoroisopropylidene) diphenol (bisphenol AF, BPAF) are two po

Mining activities in the Athabasca oil sands region (AOSR) have contributed to an increase of polycyclic aromatic compounds (PACs) locally. However, many PACs found in the AOSR, and the combined effects of PAC mixtures have not been evaluated for gen

In vitro liver toxicity tests performed using cell lines cultured as two-dimensional (2D) monolayer have limited CYP450 activity and may be inadequate for screening chemicals that require activation to exert toxicity. Metabolic competence is greatly
