Arsenic and Hg exhibited highly significant spatial variation ( p < 0.0001 for both), with the highest concentrations observed at location L2 (As: 4.56 μg/g; Hg: 0.64 μg/g) and the lowest at L6 and L4, respectively.

For Pb, a borderline significant difference was detected ( p = 0.050), with tub gurnard showing slightly higher mean values; however, this finding is limited by the high proportion of missing Pb data (68.1%).
