Concentration dataset of 8 selected trace elements in cultured rainbow trout (Oncorhynchus mykiss) and dietary exposure risks in the Missouri adult population

Abstract

Highlights Concentrations of eight trace elements in O. mykiss from aquaculture. Only Cr, in some samples, exceeded the permissible limit. EWI values of analyzed trace elements were below the PTWIs. Arsenic was the highest contributor to non-carcinogenic risk in adult consumers. Cancer risk of As, Cd, Cr, and Pb in the adult population is probable. High intake per week of O. mykiss posed health risks to the adult risk group.

Dietary exposure assessment of selected trace elements in eleven commercial fish species from the Missouri market

“…Fish feeds, at times, contain metals above the prescribed limits (Mannzhi et al, 2021;Maule et al, 2007). Other studies found chemical contaminants such as PCBs (McMullin et al, 2022) and total Hg (Ikem et al, 2021a) in feeds. Consequently, seafood may contribute to the total dietary intake of chemical contaminants in humans.…”
