¡¼Abstract¡½The study developed an effective and economical method for the analysis of PCBs with GC-ECD in surface sediment samples through evaluating the performance of silica gel and Florisil column coupled with different elution solvents with regard to consumption of solvent, sensitivity and limit of detection. The detection limits are in the range of 0.11~0.35ng/g, and recoveries of main PCBs congeners range from 77.9% to 112.1% (average is 86.8%) Finally, PCBs in the surface sediment samples in the low reach of the Yangtze River were analyzed by using the optimized method and the quality control result shows that such method is effective.

¡¼Abstract¡½Surface sediments in lower reach of the Yangtze River, collected in 2004 and 2005, were analyzed for heavy metals including Co, Cr, Cu, Ni, Pb, Zn, Hg and As. The whole concentration and their first fraction (including exchangeable, water and acid soluble phase) of BCR sequential extraction were analyzed using ICP-MS. Results showed that most heavy metals come from natural release of earth element, while increased concentration of Cu, Zn, Hg and As demonstrated anthropogenic inputs. The levels of heavy metals in upper basin were higher than that near the Yangtze estuary. Jingjiang, a deposition zone, showed combined pollution of heavy metals. At last Cu and Zn with both high whole concentration and bioavailability had potential ecosystem risk to lower reach of the Yangtze River.

With large numbers of local monitoring, the results demonstrate that GSM mobile communication base has some influence to the level of environmental electromagnetic radiation, especially to buildings in the 50 meters around GSM mobile communication base. However, most GSM mobile communication bases accord with requirement of national standard on environmental impact of electromagnetic radiation. There is no pollution from electromagnetic radiation to ambience when the equipment is running normally.

¡¼Abstract¡½In this paper, the problem of using automatic air monitoring system for the quality control chart was discussed and improved quality control of the mapping method was present. Examples have shown that the improved quality control chart could determine calibration cycle of the equipment in light of the drift condition. When determining regulatory limit, according to the difference between machines to reduce the equipment's regulatory restrictions, we can acquire more accurate and reliable results.
