Exposure to organophosphate esters (OPEs) remains a significant concern, especially in aquatic systems where these compounds can bioaccumulate organisms. However, limited information exists regarding their potential health risks humans through the food web tropical ecosystems. This study investigated levels, bioaccumulation, and trophic transfer of OPEs sediments marine fish species from Cartagena Barbacoas bays, Colombia. Twenty target were quantified fish. The average concentrations ∑18OPEs ranged 2.80 115 ng/g dry weight (dw), while ∑20OPE 212 1968 lipid (lw), with highest found carnivorous species. Trophic magnification factors (TMF) for varied 11.0 25.8 such as 2-ethylhexyl diphenyl phosphate (EHDPP), 4-isopropylphenyl (4IPPDPP), tris(2-isopropylphenyl) (T2IPPP), tricresylphosphate (TCP), indicating biomagnification within web. Biota-sediment accumulation (BSAF) ∑11OPEs 0.340 4.32, showing Spearman correlation log Kow fish: Pargo chino (r = -0.78, p < 0.05), Mojarra blanca 0.79, Lisa 0.72, 0.05). suggests that bioaccumulation certain increase lipophilicity compounds. Despite findings, human risk OPE exposure via consumption was be minimal.
