*EPI Suite (cited in Arnot and Gobas 2006); **SP, test solutions prepared with solid-phase desorption dosing system; SS, test solutions prepared from stock solutions. Further, information on substance application is provided as supporting information (Table S2). ***The specific radioactivity of the 14C radiolabelled test items was 8.19 MBq/mg (14C simazine), 5.17 MBq/mg (14C LHC), 12.71 MBq/mg (14C pyrene), and 32.18 MBq/mg (14C methoxychlor)
