Arsenic and its compounds
Description of the silver diethyldithiocarbamate method, which is based on the reduction of arsenic to arsine and the reaction of the latter with silver diethyldithiocarbamate in pyridine. Sampling, interferences, sensitivity, special reagents and equipment. The method is said to be simpler that the molybdenum methods and more sensitive than the Gutzeit method.

Ethyl silicate
Method of collection of ethyl silicate - (C2H5)4 SiO2 - in air. The analytical determination involves addition of a molybdic acid reagent to the sample to form a silicomolybdate complex which is reduced by an acid reagent. The colour is read on a colorimetric meter which a 660nm filter. Interferences have not been determined.

Description of the p-dimethylaminobenzaldehyde method, based on the addition of this aldehyde to the sample in acid solution and the spectrophotometric determination of the resulting substance. Sampling, interferences (aromatic amines and methyl hydrazine), sensitivity, special reagents and equipment.

Dimethylformamide
Method of collection and analysis of dimethylformamide - HCON (CH3)2. The substance is adsorbed in water and converted to hydroxamic acid by the addition of hydroxylamine sulphate and sodium hydroxide. The colorimetric determination of hydroxamic acid is made after addition of hydrochloric acid and ferric chloride. Concentrations of dimethylformamide as low as 5ppm (TLV 10ppm) can be determined. Other amides will interfere.

Determination of ethylene glycol in air by polarography
Stanovení étylénglykolu v ovzduší polarografickou metodou [in Czech]
Description of a method developed to determine ethylene glycol in the air of a factory producing Nitrosan 50. The method is based on splitting vicinal glycols by means of periodic acid. The reaction gives rise to formaldehyde and iodic acid which is freed from any periodic-acid excess by means of lithium hydroxide and determined by polarography. The presence of dinitro-o-cresol affects the determination by a deviation of about 3%, which is within the limits of reproducibility. The TLV which has been proposed for ethylene glycol in Czechoslovakia is 40µg/L; the method described in this article enables concentrations down to 1µg/L to be detected in air samples of 5L.

The respiratory system and harmful agents
Appareil respiratoire et nuisances [in French]
A monograph dedicated to the memory of Professor C. Gernez-Rieux which reviews co-ordinated thematic research carried out at Lille University over the last decade. Individual sections are devoted to: fundamental respiratory-system reaction processes to harmful agents; the respiratory system and occupational harmful agents (coalworker's pneumoconiosis, non-silicotic occupational bronchopulmonary disease and industrial pollution); respiratory disease due to fungal-spore inhalation, and hypersensitive pulmonary disease; bronchopulmonary disease and chronic respiratory insufficiency due to harmful agents.

Guides for short-term exposure of the public to air pollutants - II. Guide for hydrogen chloride
On the basis of a review of the documentation available as regards single or intermittent brief exposures to hydrogen chloride, the Committee has established a series of exposure limits applicable to short-term public exposures (from 10 to 60min and over) and to public emergency exposures (10 to 60min). The analytical methods available for the determination of HCl in air are briefly discussed.
