SPM analysis on groups of single aerosol particles around steel plant

Several methods for preparing samples of dispersed single aeroslo particles used in scanning proton microprobe(SPM) analysis were tested.Many elements such as Al,Si,S,Cl,Ca,Ti,Cr,Mn,Fe,Ni,Cu and Zn in the groups of different single aerosol particles from the Capital Steel Plant area were analyzed by SPM,The distributions of elemental contents in the group of single particles were mapped with three dimensional contour and the isometric.A new approach to study the group of different single aerosol particles for air pollution is developed in the present work.The results are significant to assessing the environmental impact of the dispersed single aerosol particles.     

锦凌水库水生生物群落结构及鱼产力研究

于2019年5月和2020年6月对锦凌水库的水质、浮游生物和底栖动物进行了调查研究.结果显示,锦凌水库浮游植物共检出8门116种,平均密度为7.0×106ind./L,平均生物量为3.03mg/L;浮游动物共检出4类70种,平均密度为2192ind./L,平均生物量为3.88mg/L;底栖动物共检出3门9种,平均密度为...
