[Heavy metals in the environment and their impact on the organism]. / Tiazhelye metally v okruzhaiushchei srede i ikh vliianie na organizm.

Heavy metals are chief contaminants of the environment, having an adverse effect on the population, especially on children. Results of hygienic and clinical observations suggest to us that compounds of heavy metals might cause changes in functions of metabolism and structure of some organs and systems raising the level of morbidity. It is necessary that a common system be set up of investigations, based on achievements of hygienic science both in this country and abroad; comprehensive investigations designed to study effects of heavy metals on human health be conducted; methodological approaches to the assessment of complex studies be worked out.

[Occupational aspects of modern work conditions in lead production]. / Gigienicheskaia kharakteristika sovremennykh uslovii truda pri rabote so svintsom.

Production of lead crystal, ceramic paints and roentgenologic grids is associated with air lead levels exceeding the MAC and occurrence of other toxic chemicals in air. Ambient air in populated area near crystal production appeared to contain high lead levels. The authors specified measures aimed to prevent lead influence on the exposed workers and population.

[The prophylactic use of pectin in chronic lead exposure in industry]. / Profilakticheskoe primenenie pektina pri khronicheskom vozdeistvii svintsa na proizvodstve.

An effect was studied of lead on certain physiologic, hematological and biochemical parameters in workers engaged in the lead-acid cell manufacture, as was a prophylactic action of pectin in the aforementioned groups of persons. Elimination of lead from the organism was found to be on the increase after the intake of pectin-vitamin preparation (PVP, 3-4 g daily for one month), with the above parameters returning to normal. It is recommended that regular courses of pectin prophylaxis be delivered under control of adequate tests and levels of lead in indicator biological media if we are to achieve a maximal effect in prevention of chronic lead poisoning.

[The toxicological-hygienic characteristics of surface-active substances used in the technological processes of the oil-producing industry]. / Toksikologo-gigienicheskaia kharakteristika nekotorykh poverkhnostno-aktivnykh veshchestv, ispolzuemykh v tekhnologicheskikh protsessakh neftedobyvaiushchei promyshlennosti.

The authors suggest two stages of ecological and hygienic evaluation of surface active substances widely used in oil extraction. Stage 1. Toxicological-hygienic evaluation of these substances. Stage 2. Ecological-hygienic aspects of surface active substances (migration into soil, phytotoxicity, effect on the water quality and oth.). It was established at stage 1 that proxanol, proxamin, diproxamin are compounds of minor hazard (class 4 hazard). These substances belong to local skin-irritating substances. Proxanol produces skin-resorptive effects which is confirmed by clinical signs of intoxication, reduction of weight of the experimental animals.
