Description	The toxic effects of photoproducts formed upon the photolysis of 2- and 4-chlorophenol (CP) frozen solutions in polycrystalline ice phase were determined with a bacterial luminescence test (Vibrio fisheri), and in vitro biomarker assay for dioxin-like effects (inductions of AhR-dependent luciferase in H4IIE-luc cells), and compared to the toxic effects of products of the same photoreaction in aquatic phase. Coupling photoproducts formed in ice samples (3-chlorobiphenyl-2,4-diol and 3-chlorobiphenyl-2,2-diol from 2-CP photolysis, and 5-chlorobiphenyl-2,4-diol from 4-CP photolysis) were found to be more toxic to Vibrio fisheri than parent CPs and elicited significant inductions of dioxin-like effects (the effective concentrations EC50 ~ 3 10-5 mol L-1 corresponded to known weaker ligands of AhR, such as non-planar polychlorinated biphenyls (PCBs) or polycyclic aromatic hydrocarbons (PAHs)). To complete the picture, a photoproduct formed from 4-CP (5-chlorobiphenyl-2,4-diol) was synthesized, and a detail The toxic effects of photoproducts formed upon the photolysis of 2- and 4-chlorophenol (CP) frozen solutions in polycrystalline ice phase were determined with a bacterial luminescence test (Vibrio fisheri), and in vitro biomarker assay for dioxin-like effects (inductions of AhR-dependent luciferase in H4IIE-luc cells), and compared to the toxic effects of products of the same photoreaction in aquatic phase.
