[New hygienic requirement in work with lead].

A project "Hygienic requirements for work with lead" is specified. The project covers principal hygienic requirements for production (including small and individual enterprises) where lead is the main occupational hazard and determines work conditions and prophylactic measures. The authors considered new prophylactic approaches--average shift MAC for the air of workplace (0.05 mg/m3) and monitoring of serum lead level in accordance with exposure grade.

[The functional dynamics of attention and its relation to the individual typological properties of the nervous system in middle-aged and elderly persons].

The age dynamics of attention's function and its correlation with functional mobility of nervous processes at adults in age from 21 to 74 years old were studied. It was determined that this period of ontogenesis characterized gradual and irregular determination this function. It was revealed that mean exponents of attention's qualities and peculiarities its age dynamics depended from individual-typological properties of nervous system et adults and old men. The adults with high exponents of function mobility of nervous processes at all age groups have high level of development of attention's function and slower changing and delay of beginning of involution this mental function. The adults with low exponents of function mobility of nervous processes characterized earlier beginning and intensive deterioration of attention's function.

[Physiological-occupational assessment of acoustic load with equal energy but different time and informational characteristics].

The article deals with results of experimental study comparing effects of 4 types of acoustic load--noise (constant and impulse) and music (electronic symphonic one and rap)--on hearing sensitivity, processes in nervous system and subjective evaluation. All types of acoustic load were equal in energy (on evaluation according to equivalent level during the experiment). The study included 2 levels of load--90 and 95 dB. The differences revealed demonstrate importance of impulse parameters of noise and musical load for reactions of acoustic analyzer and central nervous system. The experiments show that evaluation of harm caused by temporary and impulse noises should be based not only on assessment of specific (hearing) function, but also on parameters of central nervous system state. The authors found that music of certain acoustic and informational parameters may harm hearing function.

[Importance of hygienic monitoring in detection of etiological mechanisms of chronic lead poisoning in battery production plants].

The authors demonstrate importance of hygienic monitoring for describing the course of chronic lead intoxication among workers of storage battery production. The authors specify and describe the principles of hygienic monitoring program, grouped and individual parameters (hygienic, medical and biologic) that are risk factors for chronic lead intoxication and subjects of control. The article contains some examples demonstrating possibilities of hygienic monitoring for matching the occupational morbidity parameters of storage battery production workers with work conditions and other parameters influencing the disease.

[Comparative evaluation of prognostic models of the development of vibration disorders caused by local vibration].

The article compares the present domestic and foreign patterns of vibration disorders probability forecasting, uncovers the main causes of their difference and deals with the quest of a pattern, which is the most adequate to available empirical data. Extensive epidemiologic data on vibration morbidity helped to create a new forecasting pattern. The established dependence is expressed by an equation, a table and a plot, which enable to evaluate vibration disease risk under exposure to vibration of different levels and duration and to elucidate the safe length of service. The level of vibration was proved to reduce the latent period of vibration disease in accordance with range of exposure, probability intervals and length of service, prophylactic measures and insurance therefore should be differentiated for everyone exposed to vibration.

[Occupational morbidity due to the effects of vibration and noise in leading USSR industries and main objectives of its prevention].

The article presents data on the prevalence and dynamics of noise and vibration related occupational morbidity in different regions of the USSR, branches of industry and professional groups. Diseases caused by noise and vibration present major and ever growing occupational pathology in the Soviet Union. Particularly high morbidity rates were traced in the Russian Federation, Ukraine, Kazakhstan and Lithuania, primarily in coal mining, metallurgy, machinery construction branches of industry, and, as to occupational hypoacusis,--in metallurgy, some branches of machinery construction, automobile construction and light industry. Vibration related risk factors were revealed in such professional groups as choppers, emery polishers, tool sharpeners, loggers, drill operators; noise related risk factors--in blacksmith's works, weaving and some others. Certain decrease in occupational morbidity rate was registered before 1985 with a tendency to increase in the last 4-5 years. Prevention of vibration and noise related morbidity should include complex measures, modernization of industrial sites and health services improvement.

[Analysis of the incidence of vibration disease in machine-building industry].

A study was performed of vibration disease prevalence and morbidity dynamics for 10 years at the enterprises of the RSFSR Ministry of Machine-Building Industry. The results of the study proved that the major VD prevalence was found in automobile, heavy and energy machinery industries, machine-tool and agriculture machinery industry (80%). With regard to the morbidity rate and duration of work/D morbidity correlation, the contributors identified 8 major VD-risk professions, including those for female workers, an earlier development of the disease being more characteristic of females in some professional groups. It was established that some are less/or more liable to VD in comparison with others of the same professional group, which can be accounted for by different individual factors that influence the latent development of the disease. The revealed differences can determine the most promising techniques in VD prevention at machine-engineering plants.

[Prognostication on the development of vibration disease in laborers using manual machines].

Prognosing of vibration disease (VD) is normally made both with regard to the number of the VD cases depending on the duration of work in vibration-hazardous professions, and with respect to its latent period. The results of prognosing depend to a vast extent on the methodological principles and criteria used. The data obtained from an epidemiological survey helped to determine quantitatively the interdependence between the vibration dosage and the VD latent period calculation on the average working day dosage basis. It was also shown that in case with marked high frequency and low frequency vibrations, as well as in combinations of vibration with other industrial factors, the calculated VD period can be shortened or prolonged) by 1-3 years. Further improvement of the VD prognosing techniques should be based on the evaluation of group and individual risk-factors criteria.
