[Serum thiocyanate level as a discriminating element in evaluation of exposure to carbon monoxide].

Blood carbon monoxide concentration levels in two groups of subjects to a different degree of exposure are examined in the light of the subjects declared smoking habits and serum thiocyanate levels. The latter parameter proved an effective pointer to individual exposure to CO due to tobacco combustion. Assessment of the results showed that it could be proposed as an indicative and discriminating test of habitual exposure to CO, so as to enable expired CO and HbCO values to be interpreted in occupationally exposed subjects.

[Absenteeism and influenza. Analysis of relationship between the excess morbidity and the influenza phenomenon].

The results are reported of a survey on the influenza phenomenon made on a sampling of about 100,000 subjects from the FIAT working community. The study is based on the absenteeism information for both over and under three days absence, for the time period between October 1976 and April 1977. In addition, a tentative evaluation of the influenza phenomenon has been made not only for the overall working population but also for various age groups.

[Blood levels of lead and erythrocyte ALA-dehydrase in 200 employees of a Turin metallurgical plant. Analysis of variables connected with alcohol drinking and smoking habits].

The relationships between blood value of Pb and activity of Ala-dehydrase erythrocyte enzyme were studied in relation to the following variables: age, activity, residence, smoking habits, drinking habits. 200 adults, subdividable into occupationally exposed were examined. The data obtained showed a relationship between smoking and Aladehydrase; a relationship was also found to exist between alcohol and blood Pb and inhibition of Ala-dehydrase activity.

[Analysis of some hematological parameters and variables connected with drinking and smoking in relation to subclinical blood lead values].

Long-term investigation of the mechanisms involved in the uptake of lead and its effect on the body is referred to. The relation between smoking, drinking and some blood parameters and blood lead and Ala-dehydrase is examined. A close connection between blood lead and alcohol, but not smoking, was noted, whereas both variables led to marked inhibition of Aladehydrase. A model for the relation between alcohol and blood lead was sought. There was a significant relation between Ala-dehydrase activity and the red cell count; this was corroborated by further statistical analysis and observation of increased globular values.

[Markers of hepatitis virus A and B infection in subjects undergoing a hiring examination in a large business].

The prevalence of some hepatitis-A and hepatitis-B markers has been studied in 495 individuals (male 291, female 204) attending a preemployment medical examination at a great factory in Northern Italy between November 1978 and April 1979. A 2.0% and 13.7% incidence has been respectively found for HBsAg and anti-HBs in the whole population. A statistically significative difference has been recognized between people coming from Southern and Northern Italy, as well as between first-employment subjects and workmen or countrymen. A higher incidence of anti-HBc has been detected in men, in older age groups, and Southern immigrants, without any statistically significative difference related to their previous activities. Anti-HAV antibody has been found in 57.9% of whole population, with a greater incidence in younger people and in southern immigrants. First-employment group showed a lower incidence of anti-HAV, notwithstanding the great number of southern immigrants in this group.

[Lead. Environmental diffusion and biological aspects].

The problems raised by ambient lead are examined with reference to its uptake, absorption and metabolism in man, animal metabolism and toxicology, sub-clinical effects, and health aspects. The existing research picture of this very complex field is surveyed.

[Analysis of the seasonal pattern of blood lead levels in relation to different concentrations of atmospheric lead].

Blood lead levels have been analysed in a group of people resident in Turin in relation to different concentrations of lead in the atmosphere. Blood samples were taken in three periods of the year corresponding to seasonal maximums of pollution. Blood lead levels showed a marked decrease in the summer when the lowest concentrations are observed but the following autum sample did not show an increase. It is therefore considered likely that blood values would have been found to be increased if the final sample had been put off by 1-2 months.

[Carbon monoxide: environmental and biological aspects].

The problem of carbon monoxide as a pollutant is examined. Its physico-chemical features are considered along with the sources of pollution (natural and technological), the characteristics of the pollutant in the environment and, particularly, the effects of car and industrial emissions and of cigarette smoke on the human organism.
