[Hygienic substantiation of maximum permissible concentrations of oil products in the soils of the Republic of Belarus].

Oil products are the one out of major pollutants in soil. For reduction of the technogenic load on human beings and performing preventive measures in the Republic of Belarus differentiated hygienic rate setting for oil products in the soil have been scientifically substantiated for follows different categories of Lands: agricultural lands, defense lands, lands for recreation, historical and cultural purpose, forest lands, lands of water fund, reserve lands--50 mg/kg; settlements sand, garden housing and dacha cooperatives,--100 mg/kg; industrial, transport, communication, energy, defense and other appointments lands--500 mg/kg.

[An experimental validation of the maximum permissible concentration of a mixture of mono- and bicyclic terpenoid alcohols in water]. / Eksperimental'noe obosnovanie predel'no dopustimoi kontsentratsii smesi mono- i bitsiklicheskikh terpenoidnykh spirtov v vode.

The maximum permissible concentrations (MPC) of Viterol in water were established, which was equal to 0.14 mg/l. Its organoleptic and general sanitary thresholds were determined at the same level.

[The hygienic validation of the MPEL for the fungicide tekto in reservoir water]. / Gigienicheskoe obosnovanie PDK fungitsida tekto v vode vodoemov.

Fungicide tecto (thiabendazol) is a low-toxic compound, produces a weak skin-resorptive and local irritating effect. Cumulation coefficient is 3.96. Threshold and subthreshold doses for tecto were determined as a result of 12-months chronic experiment on white rats--3.7 and 0.37 mg/kg, respectively. The allowable 24-hours dose for human exposure to the chemical is 0.6 mg. The threshold tecto concentration according to the effect on the general sanitary regimen of water reservoirs appeared to be 1 mg/l. According to the limiting toxicological index 0.05 mg/l was recommended as tecto MAC for the water of reservoirs.
