Bottom Line: Hair mercury concentration in fishermen group was significantly higher than in control group (p < 0.01).There was no significant difference in hair total mercury concentrations between sampling areas (p > 0.05).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.).

ABSTRACT
A number of ninety-six hair samples from Sicilian fishermen were examined for total mercury detection by an Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. The mercury levels obtained were compared with mercury levels of 96 hair samples from a control group, in order to assess potential exposure to heavy metals of Sicilian fishermen due to fish consumption and closeness to industrial activities. Furthermore, the mercury levels obtained from hair samples were sorted by sampling area in order to verify the possible risks linked to the different locations. The overall mean concentration in the hair of the population of fishermen was 6.45 ± 7.03 μg g(-1), with a highest value in a fisherman of Sciacca (16.48 μg g(-1)). Hair mercury concentration in fishermen group was significantly higher than in control group (p < 0.01). There was no significant difference in hair total mercury concentrations between sampling areas (p > 0.05). 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.).

Mentions: Ninety-six fishermen from Sicily with no dental problems were enlisted for hair sampling. Ninety-six additional samples were taken from a control group working in no maritime sectors. The control group was also selected to be of Italian nationality. They were young and healthy and none of them had dental problems. They are also occasional smokers, not exceeding five cigarettes day−1. Subjects were between 35 and 45 years of age and came from six areas of Sicily: Siracusa, Messina, Trapani, Sciacca, Catania, and Palermo (Figure 1). All the hair samples examined in this study (fishermen and control group) came from these six sampling areas. A questionnaire was completed for each volunteer (all were men) in order to assess his dietary habits. The per capita fish consumption of the control group ranged from 1 to 2 days/week, while the per capita fish consumption of fishermen ranged from 5 to 7 days/week. The two groups of volunteers had an average age of about 43 years and an average height of 1.72 m. About 5 g of head hair samples was collected using sterilized plastic scissor and washed with ultrapure water for total Hg levels detection by ICP-MS method.
