To investigate the relationship between exposure to polycyclic aromatic hydrocarbons (PAHs) and mortality for specifc cancer sites, 1152 men, employed for at least 1 year at a prebake aluminium smelter, were followed-up from 1972 until 31 December 2001. Exposure to PAHs was estimated from a detailed reconstruction of the working history experienced in the(More)
In order to assess early neurotoxic effects associated with relatively low levels of mercury absorbed through fish eating, two groups of 22 adult male subjects, habitual consumers of tuna fish, and 22 controls were examined using a cross-sectional field study. The assessment included neurobehavioral tests of vigilance and psychomotor function, hand tremor(More)
A mortality cohort study (1951-1988) was conducted on 526 female workers in two lead and zinc mines in southwestern Sardinia (Italy), 310 of whom had been exposed to silica. Women exposed to silica showed a nonsignificant 38% increase in the standardized mortality ratio (SMR) for nonmalignant respiratory diseases, which was highest and statistically(More)
The exposure to DNA reactive carcinogens is known to elicit a specific humoral immunological response, with the production of antibodies toward the carcinogen adducts. Consequently, the presence of circulating anti-carcinogen antibodies has been proposed as a marker of carcinogen exposure, and as a potential modulating factor in chemical carcinogenesis. In(More)
OBJECTIVES To assess early effects on the Central Nervous System due to occupational exposure to low levels of inorganic mercury (Hg) in a multicenter nationwide cross-sectional study, including workers from chloro-alkali plants, chemical industry, thermometer and fluorescent lamp manufacturing. The contribution of non-occupational exposure to inorganic Hg(More)
OBJECTIVES The purpose of this study was to evaluate the health consequences of employment in the lead-smelting industry. METHODS A mortality study of 1388 workers and laborers in production and maintenance departments was conducted in an Italian lead-smelting plant. The vital status of cohort members was determined from 1950 to 1992. Standardized(More)
The genetic effects of occupational exposure to low polycyclic aromatic hydrocarbon (PAH) concentrations were investigated in primary aluminium industry workers. The study subjects were employed in a plant that uses pre-baked anode cells, and has relatively low PAH contamination. Forty-two male workers belonging to different job categories (anode(More)
OBJECTIVES The aim of this paper was to analyse the concentrations of HgU and HgB in three different groups: 122 workers exposed, 18 workers formerly exposed and 196 subjects not occupationally or environmentally exposed to mercury. METHODS All the subjects filled out a questionnaire concerning personal data, lifestyle, occupational or non-occupational(More)
The mortality of 724 subjects with silicosis, first diagnosed in 1964-70 in the Sardinia region of Italy, was followed up through to 31 December 1987. Smoking, occupational history, chest x ray films, and data on lung function were available from clinical records for each member of the cohort. The overall cohort accounted for 10,956.5 person-years. The(More)
The mortality of 918 Sardinian lead-smelter workers followed between 1972 and 2001 is reported. The assessment of individual exposure to inorganic lead was based on several environmental and blood lead measurements available, for each department and task, between 1985 and 2001. The mortality for all cancers was within the expected numbers (SMR 1.01, n 108).(More)
