[Toxicology and hygienic regulation of lithium and its salts in the air of work areas]. / Toksikologiia i gigienicheskoe reglamentirovanie litiia i ego solei v vozdukhe rabochei zony.

Lithium salts can impair the central nervous system and kidney function and disturb the biological oxidation as well as desamidization of biologically active amines. The suggested MAC for lithium and its salts in the air of working area is 0.05 mg/m3 (aerosol, 2nd jeopardy grade).

[Evaluation of the morphofunctional status of peripheral blood cells using the GTsMK-3 hemocytometer]. / Otsenka morfofunktsional'nogo sostoianiia kletok perifericheskoi krovi na gemotsitometru GTsMK-3.

The suggested complex method for assessment of red blood cell and leukocyte counts and membranous function helps assess the time course of cellular membrane and peripheral blood status from the minimal volumes of the blood by precise estimation of cell loss using conductometry.

[Standardization of di-chlor-di-para-xylilene, di-bromine-di-para-xylilene and di-para-xylilene]. / Materialy k reglamentirovaniiu di-khlor-di-para-ksililena, di-brom-di-para-ksililena i di-para-ksililena.

Studied were the new components of dielectric coatings: di-para-xylilene, di-bromine-di-para-xylilene, dichlor-di-para-xylilene, which manifested themselves as low-toxicity compounds free from irritating, sensitizing and fibrogenous effects. The acute action thresholds for aerosols of the paraxylilenes were established at 10 mg/m3 (with regard to general and embryotoxicity), at 5 mg/m3 for the maximal inactive concentrations.
