Abstract: The total mercury in 96 hair samples from Sicilian fishermen was detected by inductively coupled plasma mass spectrometry (ICP-MS). In order to assess the possible exposure of Sicilian fishermen to heavy metals due to fish consumption and close industrial activities, the mercury levels obtained were compared with those of 96 hair samples in the control group. In addition, the mercury content obtained from hair samples was classified by sampling area to verify the possible risks associated with different locations. The total average concentration in fishermen s hair is   μ G   g − 1, with the highest value among fishermen in Sciacca (16.48   μ G   g − 1). The hair mercury concentration of the fisherman group was significantly higher than that of the control groupn control group (). There was no significant difference in hair total mercury concentrations between sampling areas (). The results of this study indicate a greater risk of exposure to mercury in Sicilian fishermen, in comparison to the control population, due to the high consumption of fish and the close relationship with sources of exposure (ports, dumps, etc.).
