A standard method was used to evaluate the acute toxicity (96h) of fluoride on Bufo gargarizans tadpoles at Gosner stage 33. Toxicity symptoms of fluoride in B. gargarizans tadpoles included abnormal motility, loss of equilibrium and decompensation. Dose- and time-dependent increases in mortality rate were observed in response to the test fluoride. The 24h, 48h, 72h and 96h LC50 (median lethal concentration) of NaF to B. gargarizans tadpoles were 693.02 mg/L, 660.57 mg/L, 643.12 mg/L and 622.81 mg/L, respectively. The safe concentration (SC) of fluoride in water for larvae B. gargarizans was 6.2281 mg/L. Furthermore, the DNA damage caused by high-dose fluoride exposure was detected by DNA ladder. The results offered basic data to further research and highlighted the necessity of management of fluoride in water to protect aquatic animals.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"55 1","pages":"430-433"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88037522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal water source is atmosphere precipitation. And its aquifer may be the stratum of Jialingjiang formation in Lower Trias (T1j).

On the basis of exploration and practice of water right transfer in the Yellow River Basin, the construction of water right transfer in the Yellow River Basin is analyzed. The management mechanism of water right transfer consists of five parts: technical inspection, appraisal to water-saving effect, administrative approval, organization and supervision of water right transfer, verification to water-saving engineering. The result of implementing water right transfer is introduced in the respects of enhancing water use efficiency and benefits, protecting of farmers' legal right, quickening water-saving rehabilitation in irrigation district, ensuring the sustainable utilization of Yellow River water. Yellow River water right transfer type in the future is discussed. According to Yellow River water resources management practice in recent years, Yellow River water resources condition and water demand of the social and economic development in Yellow River Basin, the development directions of Yellow River water right transfer in the near future are brought forward. They are practice of water right transfer by modern agricultural water saving, practice of trans-regional water right transfer, exploration to the two-level market of Water Right transfer in the Yellow River Basin.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"78 1","pages":"1043-1046"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86613167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of acid concentration, extraction time, sludge particle size and solid/liquid (S/L) ratio on removal of Cu from industrial sludge were investigated. The results indicated that extraction of Cu by 1 N nitric acid for 90 min at an S/L ratio of 1/20 is the most economical traditional extraction conditions; the higher microwave power can increase the Cu extractable fractions; active carbon addition shortened the extraction time required to extract 80% Cu industrial sludge from 15 to 10 min. The addition of a microwave absorber, the microwave power input and the S/L ratio are the most important factors to microwave acid extraction of Cu. The results reveal that sulfuric acid was an effective extractant; Cu fraction bound to the Fe-Mn oxides was extracted. Conversely, the residue fraction remained during acid extraction.","PeriodicalId":6425,"journal":{"name":"2011 International Symposium on Water Resource and Environmental Protection","volume":"5 1","pages":"1822-1825"},"PeriodicalIF":0.0,"publicationDate":"2011-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88990942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the configuration 1, groundwater recharges lake water, while in the configuration 2 groundwater received lake water input. The dynamic relation between groundwater and Qigai Lake was caused by the rapid response to the recharge and discharge events of groundwater.

There was no significant difference in wetting front shape and the maximum depth of each treatment, and the maximum depth was 17cm, which located at the conjunction point of coverage area and infiltration area, which all were higher than that of CK. Soil profile moisture distribution of each treatment accorded to general rule, which gradually decreased from surface to deeper layer.
