[Use of personal dosimetry in the determination of average concentrations of methylmethacrylate in the air].

This article describes a method that uses sampling by diffusion dosimetry to determine mean shift concentrations of methylmethacrylate in the air of workplace. Silochrome S-80 with PMS-100 liquid phase worked as an adsorbent of methylmethacrylate vapors. Thermodesorption or elution with subsequent gas chromatography were used for extraction of the chemical from the adsorbent. The method successfully passed occupational trials in evaluation of air pollution with methylmethacrylate.

[A photometric method of analysis of cyanides].

The contributors propose a selective photometric technique for detection of sodium and potassium cyanides in different washings, sewage, overalls extraction. The technique was based on the formation of a polymetyne dye, and barbituric acid and pyridine reactions. It proved efficient in detecting the cyanides within 0.01-0.054 mg/dm3, 1-100 mg/l, 0.08-1.24 mg/dm3 with deviations not exceeding 23%. Duration of the test was limited to 25-30 min.
