[Contribution of heavy metals to the development of reproductive disorders].

In order to evaluate the role of heavy metals in the reproductive status, a complex hygienic evaluation of total daily entry of lead, cadmium, zinc, and copper in the organism, biomonitoring of metals in indicator biosubstrates, and epidemiological follow-up of the reproductive function were carried out in 6962 healthy women living in industrial cities of the Dnepropetrovsk region. Total daily entry of lead is 0.27 mg, that of cadmium 0.

[The characteristics of the air pollution of an industrial region].

[Experimental evaluation of the combined effect of the noise and aerosols in the air of steel mills].

The analysis of 3 chronic experiments on white rats pertaining to the study of the combined effect of noise at 85 and 95 dBA and aerosols containing manganese, chromium, nickel oxides and SiO2 showed that there were noted the effects caused by their combined impact. The shifts were clearly marked in the state of the endocrine and cardiovascular systems.
