title: [Hygienic evaluation of working conditions in furniture factories].
abstract: The studies embrace basic productive shops from two furniture enterprises with leading noxious factors of the work environment: toxic chemical substances, noise and vibration (local and general). The concentrations of nine chemical substances from the composition of the used acid-hardening varnishes (polishes) and carbamide-formaldehyde glue are defined. The total concentrations of the formed multicomponent mixtures of organic solvents are calculated. Data show that in a greater part of the work places are measured noise levels, surpassing the hygienic norms, from the range of medium to high frequency. The measured local and total vibrations are in the limits of the hygienic norms, provided that the exposure is limited to 15 minute daily. On the basis of the established concentration of the toxic chemical substances in the air of the work environment an assessment is made on the work conditions. The assessment is confirmed by the analysis of the objective changes in the examined specific biochemical, clinic and laboratory indices of workers. Conclusion is given that the workers from these work places are subject to high occupational risk.
