Abstract:According to the requirement of the "Environmental Protection Law of the People's Republic of China"(2014 edition),there were some problems in environmental monitoring and supervision system, such as delay in the monitoring work confronted with new type environmental problems, imperfect monitoring system, vacuum zone of supervision over the entire process, weakness of legal responsibility investigation, uninformed environmental supervision and monitoring information, slow growth of social monitoring organizations and etc. And reform orientation of environmental monitoring legislation was put forward, including establishing modern monitoring management system, enhancing active disclosure of monitoring information, strengthening whole process quality control, depending more on social monitoring organizations, propelling people oriented environmental monitoring, and refining legal responsibility of environmental monitoring.

Abstract:Land Surface Temperature (LST) is an important parameter of surface energy balance components. With the rapid development of satellite remote sensing technology, satellite remote sensing has become an important approach to retrieving LST over large areas. Various satellite based retrieval algorithms have been proposed, and the Split Window algorithm has been proved to be a high precision algorithms. In this study, the LST of Wuxi was retrieved from Landsat 8 data with the SW algorithm. The retrieved LST data were further compared with both simultaneous ground measured temperature data and the MODIS LST product. Results showed that the retrieved LST had good accuracy with errors of less than 1 K. Furthermore, the Thermal Field Variance Composite Index computed from the retrieved LST data was used to analyze the spatial distribution of urban heat island. The urban heat island effect was quantified, and the effects of different land cover types on the heat island were also investigated.

Abstract:On the basis of the remote sensing monitoring operational processes of haze pollution, EOS/ MODIS and MODO4_L2 product were chosen as the main data and the secondary data, respectively. The LM-BP artificial neural network was used to retrieve the mass concentration of regional atmospheric particles. The contribution rate of the remote sensing monitoring index and the meteorological index on the haze pollution were analyzed. The operational remote sensing evaluation index of haze pollution was selected. Based on the synchronously analysis of two typical haze pollution cases in Jiangsu Province in January 2013,the remote sensing result was basically consistent with the ground measured result. Haze pollution remote sensing monitoring can be used as an effective supplement to the ground monitoring, macroscopically reflecting the spatial regional distribution of haze pollution. 

Abstract:Three different extraction methods (perchloric acid, nitric acid potassium hydroxide and ultrapure water) were compared in determination of fluoride content in camphor leaves. In addition, instrument analysis methods including ion selective electrode and ion chromatography were discussed. The extraction was assisted by ultrasonic for 45min, discontinuously. Perchloric acid extraction got the most efficiency, but coincidence degree of curves prepared on different days, daytime deviation and the slope of the conversion coefficient were not as good as another two, but these disadvantages could overcome by adjusting pH and ionic strength before analysing; Nitrate acid potassium hydroxide method got similar efficiency as perchloric acid extraction, better precision, but more steps in determination procedure; ultrapure water extraction average effect is 80% of the former two. The results of ion selective electrode and ion chromatography varied greatly, which needed further investigation.

Through optimization, we realized the synchronous derivative of phenols, including chlorinated phenol methyl phenol and nitro-phenol .The Derivative efficiency of 14 different types of phenolic compounds in water is up to 75.5%~119%.

Abstract:A new method was established to detect the arsenic in ambient air by using impregnated filter adsorption, microwave digestion and atomic fluorescence spectrometry, which improved the original sampling method and was more effective than the wet digestion. The method greatly reduced the detection limit to satisfy emission limit requirements in the national standard GB 3095-2012.

Abstract:While discussing the actual number of probes used in inspecting dual exhaust pipes car, there existed many different points between requirements from the environment sector and actual operation of environmental inspection carried out by inspection agent. We need to find out how many probes should be used during actual inspection so as to get an accurate concentration data exactly in a scientific way. We therefore could give out a fair judgment based on the inspection result of exhaust gas. Here by in this article, we demonstrated in the following three aspects: inspection specification; verification based on comprehension; detailed analysis of the construction image of exhaust pipe.

Abstract:Compared with atomic fluorescence spectrometry (as the national standard method) in determining the total mercury in soil, the DMA 80 direct mercury testing method had a better detecting limit. Precision and accuracy satisfied the requirement of analyzing practical soil samples. Furthermore, there is no significant differences between two methods on the basis of analyzing 30 practical soil samples because of its fast, accurate, non pollution.

Abstract:In this paper, the meteorology of a typical air pollution episode in Beijing City was investigated by combining observed data and the WRF meteorology model from January 9 th to 15 th ,2013.The weather conditions, atmospheric environmental background and mechanism of formation about this heavy air pollution were all analyzed. The results showed that during this serious air pollution incident, the air quality index in Beijing jumped to the level five from 9th to 10th,maintained level six from 11th to 13th, reduced to level five in 14th and ended in 15th with level three.The average concentration of PM2.5 was 323μg/m3 from January 10th to 14th;the ground meteorological elements characterized mainly as average wind(1.47 m/s), average humidity(73.6%), 24 h average temperature transformer(-2.72~2.68℃)and 24 h average pressure transformer(-3.65~2.63 hPa). The situation was closely related to the local meteorological conditions; the stable atmospheric circulation continuously provided favorable environmental field for this heavy air pollution. Small wind speed, high humidity, low PBL, lasting inversion layer were the main reasons for this heavy air pollution incident and ground wind convergence, sinking motion in the boundary layer were the important causes of this heavy air pollution incident.

Abstract:According to the 2000 2012 data of national urban wastewater discharge, the GM(1,1) mode and prediction function were established. The prediction function was assessed through the posterior variance test and the model was used to predict the 2013 2017 urban wastewater discharge. Finally the suggestions and measures about the control of urban wastewater discharge were proposed.

Abstract:The pollution levels of 5 kinds of inorganic anions (SO2-4、NO-2、NO-3、Cl- and F-) in atmospheric PM2.5 in 7 points in Kunshan were determined synchronously with ion chromatography technique. Results showed that average concentrations of 5 kinds of ions in summer atmospheric PM2.5 were in order of SO2-4> Cl-> NO-3> F-> NO-2, and the autumn average concentration order was SO2-4> NO-3 > Cl-> F-> NO-2. The amount of SO2-4、NO-3 and Cl- in PM2.5accounted for more than 20% . Besides the F- the average concentration of ions in fall was higher than in summer. The value of ［NO-3］/［SO2-4showed that stationary sources in kunshan atmospheric particulate matter pollution which still accounted for a large proportion. However, most of the ratio of the measuring point is close to 1, which showed that mobile source of pollution was also a major pollution source of atmospheric particulates in kunshan.

Abstract:With the economic development of Taihu Lake watershed and the continuous usage of aquatic resources, the outbreaks of aquatic plants severely hinders the improvement of water quality and sustainability of ecosystem of Taihu Lake. When these aquatic plants died, the water quality had potential to be exacerbated, which posed a great threat to the drinking water safety in Suzhou City. Based on four years investigation on the community structure, distribution and seasonal cycle of aquatic plants in Taihu Lake, a long term monitoring primary system were established, which supported the integrated management for government, as well as played a role of model for the national aquatic plants monitoring work.
