Unraveling the mysterious pathways of pollutants to deepest oceanic realms holds critical importance for assessing integrity remote marine ecosystems. This study tracks transport into depths oceans, a key step in protecting sanctity these least explored By analyzing hadal trench samples from Mariana, Mussau, and New Britain trenches, we found widespread distribution organophosphate ester (OPE) flame retardants but complex pattern OPE regions. In Mariana Trench seawater column, concentrations range between 17.4 102 ng L–1, with peaks at 500 4000 m, which may be linked Equatorial Undercurrent topographic Rossby waves, respectively. Sediments, particularly (422 g–1 dw), showed high affinity, likely due organic matter serving as medium, influenced by "solvent switching", depletion", "filtering processes". Amphipods three trenches had consistent levels (29.1–215 lipid weight), independent sediment pollution patterns. The OPEs amphipods appeared more surface-dwelling organisms, suggesting influence depletion". highlights need an improved understanding deep-sea pollutant sources transport, urging establishment protective measures habitats.

Abstract Hadal trenches have recently been recognized as hotspots for organic carbon burial and degradation in the deep sea owing to its distinctive “funnel‐shaped” topography frequent tectonic activity. In this study, we analyzed dissolved (DOC) concentration, optical properties, molecular compositions of water‐extractable matter (WEOM) sediment samples collected along two transects spanning diverse marine environments New Britain Trench (NBT) area. A significant positive correlation between DOC concentrations total (TOC) contents sediments emphasizes crucial role (OM) supply production hadal environment. addition, parameters (e.g., fluorescence index, a 350 /DOC) suggest remarkable influences terrestrial OM on composition (DOM) NBT sediments. Indeed, correlations stable isotopes sedimentary TOC (δ 13 C) related (SUVA 254 , /DOC, S R humic‐like) indicate that microbial has an important impact DOM. Moreover, analysis DOM showed increased aromaticity double bond equivalents equivalent western landward core axis cores, also suggesting enhanced OM. The input into led aromatic, refractory, high weight Our findings implications understanding fate ocean.
