This study delves into the unexplored distribution and accumulation of chlorinated paraffins (CPs), pervasive industrial contaminants used as flame retardants plasticizers, within hadal trenches, some Earth's most isolated marine ecosystems. Analysis sediments from Mussau (MS) Mariana trench (MT) reveals notably high total CP concentrations (∑SCCPs + ∑MCCPs) 10,963 14,554 ng g–1 dw, respectively, surpassing those in a reference site western Pacific abyssal plain (8533 dw). In contrast, New Britain Trench (NBT) exhibits lowest (2213–5880 dw), where correlates with clay content, δ13C δ15N values, but little organic carbon depth. Additionally, amphipods these trenches display varying levels, MS reaching concerning (8681–16,138 lw), while MT-1 show (4414–5010 lw). These bioaccumulation trends appear to be primarily influenced by feeding behaviors (δ13C) trophic levels (δ15N). Utilizing biota-sediment factor values principal component analysis, we discern that CPs sediment may come surface-derived particulate matters, above carrion. Our findings elucidate profound impacts emerging pollutants on least explored
