[Occupational hygiene in industrial assembly work].

Data on occupational hygienic characteristics of industrial-assembly work are reported, which have not been subject upto now to such studies. Complex hygienic evaluation of the basic physical and chemical factors of the working environment is performed as well as physiological and ergonomic characteristics of the principle professional groups, analysis of the occupational diseases and diseases with temporary disability and clinic and laboratory examinations on the workers. The following peculiarities of occupational hygienic aspect are established: 1.

[Evaluation of the immune status of pupils of the Secondary Vocational-Technical School of Rubber and Plastics].

Children of a Secondary Polytechnical school of rubber and plastics were studied. The task aimed at tracing the immunological reactivity of the young generation in the conditions of the chemical industry. The following methods were used: reaction for reactivity of the neutrophylic leucocytes, defining of hemoglobins G, M, E, establishing the complement in serum, the skin autoflora condition, assessment of the microbic saliva content.

[Natural immunity of the pupils in a secondary vocational and technical school for rubber and plastics].

In connection with the reconstruction of the educational system and occupational training of the youths, the problem of the effect of the occupational factors on the organism of the juveniles is of exceptional importance. The search of early changes by the application of immunological tests in that aspect is very rational. The state of microflora of the deep layers of the skin, the microbic contamination of nasal mucosa have been studied as well as the content of complement in serum and serum immunoglobulins G, A and M and the phagocytosis in the students from SPTS.

[Determination of the mean length-of-service and mean daily exposure to lead of workers in battery manufacture].

The determination of the occupational risk at the working places by only comparing the lead concentrations determined in the air of the working environment and MAC is not sufficiently complete, if consideration is not given to the length of service of the workers in contact with that metal. The determination of the mean daily exposure is of great significance in that case as well as the number of the days during which the workers had been exposed to the noxious effect of lead. That is why, the application of the method of A.
