Problems in establishing dust allowable concentrations were evaluated. Topics addressed included trends in the development of dust allowable concentrations, general structural construction of dust allowable concentrations, and the study method of dust allowable concentrations. Purposes of classification were to simplify the method, speed up establishing concentration, and benefit monitoring. Seven categories were classified according to dust characteristics and four categories were classified according to extent of occupational harm done by the dusts. Animal experiments in conjunction with epidemiologic data were suggested as a valid means of establishing dust hygienic standards. The authors conclude that it is very important to set up a systematic study method for pulmonary toxicity experiments. It is advisable, from technical development strategy, to select a practical and feasible method.
