Water pollution control planning for the Taizi River watershed,a typical Chinese case study,is presented in this paper. Based on comprehensive *** quality in the watershed was assessed and predicated;water quality models for the river and reservoir were built;and function of water bodies and environmental assimilative capacity were determined ;and then the planning for industrial pollution sources and concentrated sewage treatment were made respectively.

background precipitation in Lijiang, China was investigated. Results showed that the chemical composition of atmospheric background precipitation mainly comes from fly ash and continental atmospheric transfer, and does not have any obvious correlation with oceanic aerosol, taking Amsterdam in the Pacific Ocean and St. Georges in the Atlantic Ocean and Katherine, Australia as examples for analysing. 

A continuous haze episode with high concentration of fine particulate matter occurred in Shanghai from May 19th to May 21st, 2010. Average hourly concentration of PM2.5 reached （0.096±0.041） mg/m3 during these three days. Results of semi-continuous monitor of water-soluble ions in aerosols indicated that three secondary ions, sulfate, nitrate and ammonium, were the main contributors to this haze episode, accounting for about 70% of PM2.5 mass concentration. At the first day’s night, nitrate formation rate was fast due to high temperature, low relative humidity and sufficient gaseous precursors, which caused high nitrate concentration. In the second day’s morning, another nitrate peak occurred due to favorable reaction conditions and enough atmospheric oxidation capacity. On the third day, concentration of sulfate instead of nitrate was high because the sulfate aerosols were transported back from sea after secondary transformation from SO2, which was emitted from human activities on land. Because of different transformation mechanism and different reaction factors, nitrate and sulfate peaks occurred alternatively, forming continuous haze event. Therefore, nitrogen oxides and sulfur dioxide should be controlled synergistically to effectively control haze in Shanghai. For nitrogen oxides, local emission sources should be controlled strictly due to the fast transformation rate and complex effects. For sulfur dioxide, attention should be paid to regional joint control due to its long-range transportation.

Organic carbon (OC) in definitely small area sediments(according to marine dimension)off the Huanghe River Estuary is investigated in order to evaluate the feature of regional difference of physical and chemical properties in marginal sea *** distributions of OC in sediments with natural grain size and the relationship with the pH,Eh ,Es and Fe3+/Fe2+ are *** addition,OC decomposition rates in surfacial/subsurfacial sediments are *** concentrations range from 0.26% to 1.8%(wt)in the study area. Significant differences in OC content and in horizontal distribution as well as various trends in surfacial /subsurfacial sediments exhibit the feature of regional difference remarkably in marginal sea sediments. The complicated distribution of OC in surface sediments is due to the influence of bacterial activity and abundance, bioturbation of benthos and physical disturbance. The OC decomposition rate constant in surfacial /subsurfacial sediments ranges from 0.009 7 to 0.076 a-1 and the relatively high values may be mainly related to bacteria that are mainly responsible for OC mineralization;meio-and macrofauna affect OC degradation both directly, through feeding on it, and indirectly through bioturbation and at the same time coarse sediments are also disadvantageous to OC *** almost all the middle and bottom sediments the contents of OC decrease with the increase of deposition depth, which indicates that mineralization of OC in the middle and bottom sediments has occurred via processes like SO reduction and Fe-oxide reduction.

A series of indicators, including serum lysozyme activity, G-banding chromosome aberration (G-banding CA) analysis, sister chromatid exchanges (SCEs), chromosome aberration (CA), T-lymphocyte transformation rate (TcTR),-GT, GPT and AKP, were employed in the present survey among occupationally vinyl chloride (VC) exposed workers and inhabitants living in VC polluted area in a polyvinyl chloride (PVC) factory. The results showed that the serum lysozyme (S-LZM) activities in Group 3 (adult inhabitants exposed to 0.20 mg/m3 VC for at least 8 years), Group 2 (workers exposed to 4.1 mg/m3for at least 7 years occupationally), Group 1 (workers exposed to 25.7 mg/m3 for at least 2 years) were significantly higher than control. G-banding CA analysis showed that the total chromosome breakage rates in both Groups 1 and 2 were higher, but no difference existed between Group 3 and control. Only Group 1 was observed having higher SCEs, CA level and lower TcTR than control. AKP levels in Groups 1 and 2 were higher than control,but noγ-GT and GPT differences were found among groups. The study also suggests that G-banding CA analysis is more sensitive than CA and SCEs

Two pollution zones in middle and lower reaches of Hanjiang River were selected for studying restoration processes. In each zones 6 stations were set up in upper stream of sewage outfall, 50m, 100 or 150m, 250 or 525m and 1250 or 3500m apart from the outfall. Chemical monitoring and microbial community biomonitoring were carried out simultaneously. Either the chemical monitoring or the biological monitoring proved the self-purification process of water body along with the increased distance from the sewage outfall. 4 biological parameters (species number of protozoa, percentage of phytomastigophora, diversity index and heterotrophy index) and parameter Seq of the colonization process all have statistically significant correlations with chemical comprehensive pollution indexes Pa and Pb.

The exploitation of coal, petroleum and natural gas in northern Shaanxi not only promoted the rapid development of economy, but also brought about enormous pressure to fragile ecology and resulted to severe water pollution, water and soil loss, vegetation destruction and other ecological environmental problems, so many countermeasures were put forward according to these problems, such as greatly developing circular economy, conducting cleaner production in petroleum enterprises, continuously renewing mining technology and so on.
