A Moroccan study of marine samples from the Gulf of Al Hoceima found total arsenic concentrations of 122.9 milligrams per kilogram of dry weight in shrimp and 103.3 milligrams in red porgy, compared with lower levels in sardines. The health risk index exceeded the reference threshold of 1, reaching 10.29 for shrimp, 8.01 for red porgy, and 1.35 for sardines; arsenic accounted for more than 85% of the index value. The study noted that its estimates assumed that 3% of total arsenic was inorganic, without directly measuring its chemical forms, and called for further analyses to identify its sources. It also stressed that the presence of arsenic does not necessarily mean there is an immediate health risk.
