摘要:
The objectives of this investigation were to determine the mercury content inan assortment of commercially available processed tuna samples and unprocessed fish fillet andseafood samples by applying a direct mercury analysis technique. The mercury concentrations in theprocessed tuna products ranged from 0.0329 to 0.412 mg/kg. Significant variability in the measuredmercury content was observed across all tuna packing and packaging methods, even for products fromthe same manufacturer. Products that were labelled to contain albacore tuna generally had highermercury levels than products that were labelled to contain light tuna, although overlap in mercurycontent was observed. The mercury content of fish fillets ranged from 0.00351 to 1.85 mg/kg. Thedetermined mercury concentrations for the catfish fillet, tilapia fillet, shrimp, and scallopsamples were all relatively low (<0.0400 mg/kg) compared to the other unprocessed seafood *** tuna and swordfish fillet samples had higher mercury content relative to the test samples, withconcentrations ranging from 0.0833 to 0.575 mg/kg and 0.872 to 1.85 mg/kg for tuna and swordfish,respectively..
