Inorganic and organic forms of arsenic (As), as well as omega-3 fatty acids were measured in 578 fish/seafood samples that belong to 15 species of commonly consumed seafood in Kuwait. Arsenic speciation data, with the toxicological profile of inorganic arsenic (iAs) and fish consumption rates were applied in a probabilistic risk assessment to estimate the risk from exposure to iAs. The nutritional benefits of omega-3-fatty acid levels in various species of fish were taken into consideration. Results showed that the mean daily intake of iAs through fish consumption among the Kuwaiti population was 0.058 µg/kg/day, and the 95th percentile was 0.15 µg/kg/day. Although the mean intake level did not exceed the incremental lifetime cancer risk (ILCR) at 1 × 10−4, the 95th percentile of iAs intake showed an ILCR of 2.7 × 10−4. Kuwaiti children (aged 6–12 years) were found to have a higher mean intake of iAs at 0.10 µg/kg/day with 68% of children in this category, exceeding the risk specific dose associated with an ILCR of 1 × 10−4. The fish species, hammor (grouper; Epinephelus coioides), is the top contributor to iAs intake, and tuna is the major source of omega 3-fatty acids for the Kuwaiti population.
