“…For that reason, lower hair mercury contents registered in older humans could indicate a change in either the protein metabolite or the synthetic processes of hair growth. 16 The average mercury concentration in hair of the 50 males sampled was 7.03 p.g/g, while that of the 56 females was 8.59 p.g/g ( Table 2) . The frequency distribution was similar in all concentration ranges for both males and females (t = 0.60; P < .05).…”

The mercury content in hair of the population in Madrid (chosen randomly) was in the range of 1.29-129.47 micrograms/g (geometric mean = 7.96 micrograms/g). The mean mercury content in hair of occupationally exposed workers was 12.70 micrograms/g (range = 2.91-65.43 micrograms/g). The highest means, which were found in two families (i.e., 67.89 micrograms/g and 92.47 micrograms/g, Families A and B, respectively), probably resulted from external factors. No statistically significant variations in the mercury concentrations in hair were found with regard to sex, age, or dental fillings. A significant correlation (r = 0.785; P less than .01) was found between the concentration of the total mercury found in nursing infants and their mothers.

Mercury exists in various chemical forms. The important forms from a toxicological viewpoint are the metallic form, also called the elemental form, the divalent inorganic forms and methylmercury compounds. Elemental (Hg 0 ) mercury has a high vapor pressure and the vapor causes a number of cases of poisoning via inhalation. Classical mercury poisoning is characterized by a triad of signs, namely tremors, erethism and gingivitis. Mercurial erethism, which is characterized by behavioral and personality changes such as extreme shyness, excitability, loss of memory, and insomnia are also observed. Recently, the effects of mercury exposure at levels around 0.05 mg/m 3 or lower have been of concern and may include minor renal tubular damage, increased complaints of tiredness, memory disturbance and other symptoms, subclinical finger tremor, abnormal EEG by computerized analysis and impaired performance in neurobehavioral or neuropsychological tests. Abnormal gait, dysarthria, ataxia, deafness and constriction of the visual field are typical of the symptoms of methylmercury poisoning observed in Minamata and Iraqi outbreaks, as well as in occupational methylmercury poisoning cases. Furthermore, an infant born to a mother with excessive methylmercury consumption showed various neurological disturbances and delayed development. Since several populations are believed to be still exposed to methylmercury through the consumption of fish and sea mammals, neurobehavioral deviations in children of these populations have recently been investigated.
