Background:
The wide use of volatile organic solvent-based products in wood carpentry and the possible effects of long-term exposure to low dose mixtures of these solvents prompted an investigation in a group of small enterprises.
Objectives:
The investigation aimed at estimating risk in wood carpentry work via assessment of exposure.
Methods:
Exposure to solvents was studied in a group of 13 enterprises (selected from a group of 52), via personal samplings, both active and passive. The solvents to be examined were selected on the basis of the information contained in the technical-toxicity sheets of the products used in these factories.
Results:
The results show an average exposure generally within the TLV-TWA recommended by the various industrial hygiene associations. However, considering the wide variability of the concentration values observed, the possibility that these limits might be exceeded in the long term cannot be excluded. Comparison of the results of active and passive samplings, showed a substantial similarity of the two systems, with evident advantages of the passive system, as far as ease of use, workers' acceptance and costs are concerned.
Conclusions:
The results of this study can be a useful reference for all those (employers, occupational physicians, technicians, workers' representatives) who are required to take preventive measures especially in cases where environmental investigations are hindered by technical difficulties or are not regularly used in evaluation systems.
