ABSTRACT
The residues of surfactants that are present on textile materials were found to affect the surface charge of tissues. If physical properties of clothes materials, such as electrifiability, the positive or negative charge, resistivity, hygroscopicity are known, you may predict the values of residues of surfactants to be adsorbed onto the surface of tissues.

Hygienic and toxicological investigations of soil, plants, and animals have shown that the superphosphates made from Algerian phosphorites little differ from those made from the apatites of the Kola Peninsula. Superphosphates A and B should be referred to as hazard class IV and the superphosphates treated by ammonium should be classified as hazard class III.

Anionic surfactant PO-ID at the level of 10, 25 and 50 kg/ha did not depress biological activity of soil and stimulated nitrogen metabolism. Water-migration and translocation indexes of this surfactant should be studied.

Use of surface-active substances (SAS) in the oil-extracting regions of the Ukraine should consider the fact that this is a rather small territory, densely populated, with environmental water and soil problems, significant contamination of several areas by pesticides, mineral fertilizers and complicated by the Chernobyl accidents sequels. SAS may influence the ecological-hygienic balance of the environment, they may enhance migration of many ingredients, increase their toxicity. The authors propose several measures aimed at improving the quality of preventive and actual state inspection over the oil enterprises.

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.

Urgent problems of the interaction of surface-active substances (SAS) with other ingredients under the conditions of chemical soil pollution are discussed, in particular, under the conditions of irrigation of agricultural fields with treated municipal sewage containing detergents. Before the beginning of the irrigation season the content of anion SAS in the arable layer of the soil is 2.02-2.66 mg/kg. In the middle of the vegetation period the quantity of detergents is increased 3-4 times fold. The authors suppose, that SAS may influence translocation of heavy metals from soil into plants. However, this question should be studied more carefully in the conditions of field experience with various SAS concentrations in soil.

Results are discussed of research studies on hygienic evaluation of the most spread surface-active substances in the USSR Hungary. Anionic substances were shown to possess the most pronounced skin-irritating effect while amphoteric substances were shown to possess the most pronounced skin-irritating effect while amphoteric substances produced the least effect. For efficient joint studies the Soviet and Hungarian methods should be unified.

It was established in experiments conducted on white rats that application to the skin of sulphonol and cintamide--5 for a period of three months result in morphological disorders of the ultrastructural organization of the epidermis, especially of the structure of intercellular contacts. A mixture of these substances produces a more severe noxious effect on the structures. These substances produced also a local effect on the skin microcirculation. The authors propose a scheme for explanation of the mechanism of structural-functional changes of the skin in local applications of surface-active substances.
