The accumulation of metalloids in the food chain can pose a great risk to human health and aquatic biota. The aim of this study was to evaluate the repartition, ecological and health risks of arsenic in surface sediments from a fluvial-lagoon environment, between the Comoé River and Ebrié Lagoon in Côte d'Ivoire. Arsenic contamination levels in sediments were evaluated using the pollution indices. The ecological risk was investigated by potential ecological risk index. The non-carcinogenic and carcinogenic risks indices were used to assess human health risks. The results showed that total concentrations of arsenic (2.92 ± 0.27 - 5.42 ± 4.6 mg/kg) were higher than the Upper Continental Crusts value (2 mg/kg). The mouth of the Comoé River was also found to be one of the most contaminated fluvial-lagoon environments. The sediments were moderately contaminated by arsenic. The non-carcinogenic risk indices values were ranged from 1.49×10-2 ± 1.36 ×10-3 to 3.48 ×10-1 ± 2.95×10-1, indicating low adverse effects both for children and adults. The total carcinogenic risk showed low potential carcinogenic effects both for children and adults. However, the values of non-carcinogenic risk and the total carcinogenic risk indices for children were found to be higher than those for adults, suggesting that children are most exposed to deleterious effects than adults. The study also demonstrated the low mobility of arsenic. Further studies including the determination of arsenic total concentrations in fish, the assessment of the ability of fish to accumulate arsenic from the sediments, and the mobility assessment using in situ diffusive gradients in thin films (DGT) method will be investigated to better understand the fate of arsenic.
