A set of 45 Persistent Organic Pollutant were analysed in surficial mangrove sediments at 21 stations. Chlorinated Pesticides (CLPs), Polychlorinated Biphenyls (PCBs) and Polycyclic Aromatic Hydrocarbons (PAHs) have concentrations ranging from 2.2 - 27.4, and 83 - 544 ng/g, respectively. The most abundant CLPs were endosulfan, alachlor, heptachlor, lindane (gamma-HCH) and DDT, which metabolites pattern revealed recent use. Selected PAHs diagnostic ratios show pyrolytic input predominantly. The sum of 7 carcinogenic PAHs (SC-PAHs) represented 30 to 50% of Total PAHs (TPAHs). According to effect-based sediment quality guidelines, the studied POPs levels imply low to moderate predictive biological toxicity. This study contributes to depict how far water resources are shifting within what is now termed the Anthropocene due to increasing local pressures in developing countries or African countries. specialized Pesticides Polycyclic aromatic hydrocarbons Polychlorinated biphenyls Sediments Mangrove Africa CAMEROUN DOUALA 038 082 102 160 111542 [15 ] 2020 0025-326X https://www.documentation.ird.fr/hor/fdi:010081264 10.1016/j.marpolbul.2020.111542 0025-326X [F B010081264] https://www.documentation.ird.fr/hor/fdi:010081264 https://www.documentation.ird.fr/intranet/publi/2021-05/010081264.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-05-17 2025-02-24 fdi:010081264 fre
