  • Title: [Evaluation of work environment in the flax textile industry. V. Air microflora in the flax spinning and flax weaving rooms].

    Journal: Med Pr; 1980; 31(2):91-7. PubMed ID: 7421569.
    Abstract:
    Microbiological air pollution in spinning and weaving rooms was determined by aspiration impinger using an aeroscop (Chirana, Czechoslovakia). The air samples were taken on Petri dishes with Bacto-broth-agar (Difco) or Bacto-blood-agar (Difco). After incubation at 37 degrees C for 24 h the number of bacterial or mould colonies and bacterial cells per 1 m3 of the air was calculated. The number of bacterial cells in flax spinning rooms ranged from 10.5 X 10(3) to 12,5 X 10(4), while in flax weaving rooms--from 2,4 X 10(3) to 10(4) per 1 m3 of air. In the examined samples of the air the bacterial pollution was found to dominate (45,1--95%). Gram-positive sporing bacteria were most frequently recognized. In the air of weaving rooms some moulds: Mucor sp., Circinella sp., Hormodendrum sp., Vetricillum sp., Aspergillus sp. and Penicillum sp. were also found (16.8--54%). It was observed that the microbiological air pollution in spinning and weaving rooms of flax industry was greater than in cotton industry. A wet technology of flax spinning promotes microbiological pollution in the air of this kind of workposts. A high level of mould cells in the air at workposts enhances the risk of workers' exposure to mycotoxins.
