摘　　要：报告了硼加工车间空气中粗、细颗粒物的分布,包括粒子数量分布和质量分布。鄂破、球磨、雷蒙磨车间的粉尘质量浓度分别高达28,33和23mg m3。粉尘中PM10所占比例分别为62 1%,62 7%和56 5%。而在PM10中,细粒子比例较低,分别为10 1%,14 2%和9 22%,但PM2 5的质量浓度分别为1 76,2 94和1 20mg m3。用ICP-MS测定的球磨和雷蒙磨车间空气中硼的质量浓度分别为425 6和669 1μg m3,其污染水平是相当高的。The distributions of fine and coarse particles in the air of boron processing plants,including the number concentration and mass concentration,were reported.The dust concentrations in the workshops of crushing,ball milling and Leimond milling are up to 28,33 and 23 mg/m^3,respectively.The percentages of PM\-\{10\} in the particles are repectively 62.1%,62.7% and 56.5%,whereas the percentages of fine particles in PM\-\{10\} are relatively small,with 10.1%,14.2% and 9.22%,respectively.However,the mass concentrations of PM_(2.5) are respectively 1.76,2.94 and 1.20 (mg/m^3.)In addition,the aerial boron concentrations in ball milling and Leimond milling workshops are analyzed with ICP-MS,with the results of 425.6 and 669.1 μg/m^3,respectively,which indicates quite serious pollution.
