摘要: Abstract Concentrations of 11 trace elements in three tissues porbeagle shark Lamna nasus (n = 33) were determined. The maximum observed concentrations Cd and Pb muscle 0.04 0.01 mg kg − 1 , respectively, all samples below European seafood limits for these metals. Hg either the red or white that exceeded regulations one-third specimens. concentration, however, increased with length, fish > 195 cm had > 1.0 mg kg a value 2.0 mg kg . Fe Cu were, on average, 9.7 10 times higher than nearby muscle, respectively. Mn, Zn, As Se also found significantly muscle.
