[Industrial pollution by solvents with special reference to limited values for mixtures].

The report concerns the AA. experience in the field of pollution due to solvents, particularly in the following industries: shoe manufacturing, graphics and the production and application of paints. The exposure risk in these 3 indutries is quantitatively and qualitatively defined based on data obtained from the gas--chromatographic analysis of 238 work environment samples. The data are evaluated with reference to limit values established by the ACGIH, the Italian Society of Occupational Medicine and the Italian Society of Industrial Hygiene. In additon to the evaluation with respect to the TLV and VLP, the hygiene parameter of TLVs for mixtures is evaluated in the field of industrial hygiene.
