[Environmental and biological monitoring of subjects occupationally exposed to precious metals (gold lost-wax casting)].

Environmental monitoring during lost wax casting in jewelry handicrafts was performed for gold, silver, zinc and copper by means of personal samplers and ICP-AAS techniques were used for determining airborne metals. Personal sampling was prolonged for a working week by continuous monitoring during 8 hours shifts, replacing the membrane filter every 2 hours, in 6 workers; in the same workers urine samples were collected during the week and levels of Au, Ag, Zn and Cu were measured by ETA-AAS. During casting process Ag air concentrations ranged 0.27-0.6 mg/m3 while mean levels of Au, Cu, and Zn were 0.028 0.030 and 0.056 mg/m3 respectively. Urinary excretion of Ag (I) determined by solvent extraction and separation by liquid anion exchanger proved very high, after 24-36 h from the casting processes.

[Monitoring of occupational activities under the risk of heat stress: use of mathematical models in the prediction of physiological parameters].

Some authors proposed mathematical models that, starting from standardized conditions of environmental microclimate parameters, thermal impedance of the clothing, and energetic expenditure allowed the forecast of the body temperature and heart rate variations in respect to the basal values in subjects standing in the same environment. In the present work we verify the usefulness of these models applied to the working tasks characterized by standardized job made under unfavourable thermal conditions. In subject working in an electric power station the values of the body temperature and heart rate are registered and compared with the values obtained by the application of the studied models. The results are discussed in view of the practical use.

[Simplification of periodic audiometric tests in persons exposed to industrial noise. An operative proposal].

Today the pure tonal audiometric test is the most used in periodical screening of the "hypoacusis" hazard in exposed patients because of its easy performance. The high number of patients to be tested and the screening frequency suggested to simplify the annual checks by testing only some of the frequency to be tested is made on the basis of the first complete audiogram performed according to a scheduled scheme. Available screening data and testing on the field show that a consistent reduction in testing time is possible and that the complete exam is reliable.

[Retrospective study of the morbidity in a group occupationally exposed to chlorotriazine herbicides: preliminary results].

Two different groups of workers, involved in production or formulation of chlorotriazine herbicides during the last 10 years, have been retrospectively studied for occurrence of diseases related to the exposure to Atrazine, Simazine, Propazine, and Terbuthylazine. A control group has been selected between clerical workers of the same plants. Subjects exposed to the different compounds have been studied for inhalator and dermal exposure by active sampling, skin pads, and hand washings; samples have been further processed and specifically analysed. Urines have been studied for the presence and concentrations of mono and bidealkylated triazine metabolites. Exposure data have been collected during the last five years and extrapolations have performed for exposures in the preceding years. Clinical finding and laboratory data for all workers have been obtained from medical surveillance records. Data available for the last 10 years have been evaluated to highlight possible differences between the investigated groups.

[Burns risk caused by the interaction of NIR at radiofrequency and metal structures at a building site].

This study pointed out an induced electric field originated from two radio aerials and measured on two cranes being in an neighbour building site. On the basis of the results of the calculations effectuated, it has been showed that the values of the electric field were within the IRPA reference values; although these values, the metallic structures of the two cranes seemed to interfere with the electromagnetic field as well as to create some situations of risk for the workers of the building site. At last, for this reason were suggested some techniques of primary prevention.

[Retrospective study of morbidity in a group professionally exposed to chlorotriazine herbicides].

Two different groups of workers involved, during the last 10 years, in the production or formulation of chlorotriazine herbicides have been retrospectively studied in order to verify the occurrence of diseases possibly related to Atrazine, Simazine, Propazine and Terbuthylazine exposure. A control group has been selected between clerical workers of the same plants. Exposure data have been collected during the last five years and some extrapolations have been performed to hypothesize the level of exposure in the preceeding years. Clinical findings and laboratory data obtained from ten year medical surveillance records have been evaluated to highlight possible differences between the investigated groups. A first close examination of the data concerning the anamnesis and clinical, hematochemical and functional reports of the three groups of investigated subjects does not show any pathological situation or symptoms specifically connected to chlorotriazine compounds exposure and/or significant differences between exposed and non exposed. A next series of statistical surveys involving some of the hematochemical indicators (RBC, WBC, Hb%, SGOT, SGPT, gamma GT) has been performed either on internal values of each group or on the average-values of the three groups differently exposed (production, formulation, control). The first survey was a longitudinal study, the second one was a cross sectional one. Both the investigations have excluded significant differences attributable to the occupational exposure.

[A case of occupational pulmonary siderosis: the pathogenetic and prognostic considerations].

Pulmonary siderosis is a disease which can be considered with the pneumoconioses of the so-called inert dust (either by deposit or by accumulation) and, from the earliest nosographic descriptions dating back to the thirties and forties, it has been substantially considered a benign form because of the scarce sclerogenic evolution and the preservation of discrete respiratory function. We present a case of pulmonary siderosis characterized on one hand by the importance and clarity of the cytopathological picture and on the other by the presence of changes, although modest, in lung function which confirm the most recent hypotheses in the literature on the potential evolution of pneumosiderotic diseases and their relatively less benign prognosis. From a preventive point of view the case draws attention to the need for greater control of environmental hygiene conditions in small factories. From an insurance and medico-legal point of view siderosis has recently been explicitly added to the occupational diseases which can be declared to the Italian state department dealing with occupational disease and disability payments (I.N.A.I.L.) (DPR of the 13.04.1994, section 47).

[Role and significance of information tools in occupational asthma].

Role of education in occupational asthma. Subjects' education, i.e. information and training in the specific topic, has a substantial role in several medical fields and is considered to be the challenge to reach the primary, secondary and tertiary preventive goals. In occupational medicine workers information and training is considered particularly relevant and it has been included in a recent governative law regarding prevention and health care at the workplace. The present short review deals with the role of education in occupational asthma, which at present appears the most frequently compensated occupational lung disease.

[Diagnosis and consultation at the Hospital Unit of Occupational Medicine (UOOML)].

The author describes the operating course of the Occupational Medicine Operating Units (OMOU) in our region. (Lombardia) These Units, born as a second level support to the Basal Occupational Medicine Units, greatly enlarged, as time passed, the limits of their users together with the charge of preventive duties ordered to the employers by the recent laws regarding Occupational Hygiene. (DLgs 277/91-DLgs 626/94) The author also illustrates the variety of the diagnostic demands to the OMOU according to the enlargement of the legal protection of occupational diseases and to the numerous aspects of specific job fitness. He underlines the need of multiple specialistic skillfulnesses achievable by means of a complete integration of OMOU in to the hospital to which they belong. In conclusion the author illustrates the new tasks of the OMOU in the field of the therapy and rehabilitation.
