[The mycotoxicological and dust contamination of the air in plants for the preliminary processing of cotton and hemp].

Investigations are carried out in two enterprises for primary processing of cotton and one - of hemp. On the working places were determined dust concentrations on the technological lines and the mycotoxicological pollution of the air. Examinations were made on the workers. Concentrations above the norm were established of total dust and high rate of concentration with microbes and spores of microscopic fungi from the families Cladosporium, Alternaria, Aspergillus, Penicillium and Fusarium. The proved toxic and allergenic effect of the microflora and the high concentrations of the dust are prerequisites, which impose a reevaluation of the approaches to hygiene standardization of dust from natural textile fibres. Thus the prophylaxis of occupational diseases of a large contingent of workers will considerably improve.
