| In this paper, foreign and domestic air particulate standard reference material systems and their preparing technologies were systematically introduced. The problems about domestic air particulate standard reference material were analyzed, including simple types, limited target components, and weak preparation technology. Based on foreign development experience, domestic needs and research ability, strategies and suggestions were made to improve the development of air particulate standard reference material, including to increase the kinds of air particulate standard reference materials matrix and pollutant components, to strengthen cooperation with foreign research institutions, to reinforce the scientific research, and to conquer the difficulties of preparation technology. |
