title: [Determination of organic phosphate plasticizers and solvents in the environmental air of the shoe industry].
abstract: We have carried out a laboratory research with the purpose of evaluating the absorbing capacities of various commercial active coals, equipping therefore a room where we have maintained a constant concentration of solvents in the air. We have determined through a gaschromatographic method the conditions of dimension of the test tube, the quantity in weight of coal and the speed of the flow to secure at least 4 1 of sampling. Using test tubes of 10 mm of inner diameter, 70 mm long containing 0.8 g of active coal, 20-35 mesh, with diameter from 0.33 to 1 mm2, subjected to an aspiration of 0.35 l/m, we have diluted the solvents with CS2 and determined their quantity through gaschromatographic analysis. We have completed a research of trycresyl phosphate and other plasticizers upon 54 different types of cement used in 30 shoe factories in the comprehensory of Lastra a Signa. On the cement samples and glues it has been done the mineralization with sulphonitric mixture. It has been observed that the presence of the phosphorus in the samples of the cement is not always due to the presence of phosphorganic plasticizers. We have then carried out a distillation from the cements with n-hexane and a thin layer chromatographic analysis using as comparison commercial trycresyl phosphate. The various cements examined did not contain plasticizers.
