A spring according to flow direction, drainage Huang Hai,<a href="http://www.abercrombiemadrid.com" target="_blank" class="postlink">abercrombie madrid</a>, Zhama Long and the Western Steel as the main investigation points will be located in the source area of ​​Halle jianhe Huangshui upper segment as the control points, shown in Figure 1. <br /> 1 National Environmental Protection Agency, . <br /> The above analysis, the former chemical plant in Qinghai Haibei Cr6 + contaminated by plant and soil and have the Cr6 + compounds into the ground around the plant is caused by groundwater, surface water upper reaches Nirvana water and water it Xining duo Cr6 + concentration increased the direct cause of the great threats to the environment. Cr6 + to prevent the worsening of water pollution, pollution control has become very urgent. Only speed up the chemical plant's pollution control Haibei, total eradication of Cr6 + sources in order to effectively curb the C r6 + Nirvana watershed pollution in the occurrence and ensure the continued safety of drinking water sources. Sub-departments should continue to attach great importance to this. <br />A Gold Silver Beach <br /> Abstract: Objective Line Water hexavalent chromium (Cr6 +) Pollution and pollution sources. Methods Nirvana Halle jianhe water source areas upstream as control, according to the Line to be A spring water, Niehai sewers, water sources duo it, Zama down, unitary steel bridge is set to survey sites, in 1996-2003 in water samples collected in these areas and C r6 + recorded for analysis with results 1999-2003 Cr6 + A spring with an average recorded for the 45.192 mg / L, Nirvana Niehai drainage water upstream, downstream Zama drop off and unitary steel bridge Cr6 + with water were recorded year by year, Halle jianhe i1 upstream to 2003 has not detected a Cr6 +, 2003 年 duo water source for the first time it detected Cr6 + (0.007 mg / L), A spring near the conclusion of the Qinghai Haibei Line the water under the plant is upstream of Cr6 + major source of pollution. <br /> Cr6 + monitoring to determine the value and industrial distribution of water in the upper reaches of the West Town Line as a starting point. Flow along the Line starting to BU to Xining to import a small Gap Huangshui including all tributaries within the watershed of industrial enterprises, in particular, it will be possible with the production and efflux of Cr6 + in the enterprise as the survey the focus. Along the Huangshui involved in the investigation of the state, city, county Haibei,<a href="http://www.buyghdhair.org/" target="_blank" class="postlink">buy ghd hair</a>, Huangyuan, Huangzhong County and the city of Xining. <br /> 1 Materials and methods <br /> References: <br /> <br />           <br /> <br /> <br /> spring by the Qinghai grasslands Haibei chemical pollution of chromium compounds, the Cr6 + content in the range of 25.0081.20 mg / L, the average out of GB / T 14848-1993 standards for groundwater quality standards in three categories (core 0.05 mg / L) more than 900 times, up to 1623 times the maximum exceeded, indicating that the spring water has been seriously polluted, and showed increasing trend year by year,<a href="http://www.toryburch-flats.net" target="_blank" class="postlink">tory burch flats</a>, under the Zhama Long section of the river (the paragraph were to state-controlled cleaning points) and West Section of the steel is basically increasing year by year. In the dry season, Zhama Long, West Steel paragraph often Cr6 + content of the water out of GB3838-2002 Since 1997, the Water Conservancy Department 1 per month for water quality monitoring information, by Qinghai Haibei chemical pollution of chromium compounds, Nirvana Xining section of the water surface water C r6 + concentration increasing trend, especially in the dry season C r6 + Line exceeded the water Add a serious history, exceeding the duration is also longer. The year 1997, only 1 month of monitoring values ​​exceeded in 2000 to monitor the value exceeding 9 months. May 2003, in June it twice in Xining duo by Nirvana waterfront water wells No. 1 for the first time detected Cr} +, concentrations were 0.007 and 0.006 mg / L, although did not exceed the standards of GB3838-2002 However, on the water source has been a security threat. May 2003 with the 1st and at the same time sampling and monitoring of the Line section of the water right duo C r6 + concentration in surface water is 0.159 mg / L, beyond the GB3838-2002 standard in the class of Cr6 + III (0.05 mg / L) 2 times. <br /> Pollution survey, nirvana Nirvana of water flow over the West area of ​​steel section of Qinghai Haibei addition to the chemical plant, but did not find other possible pollution of Nirvana contribution of Cr6 + with water discharging unit, the former chemical plant Haibei Nirvana is to investigate the region upstream of the only water containing C r6 + efflux sources of pollutants. Our detailed investigation of the plant also illustrates this point. The plant is located in water source areas Haibei Line Gold Silver Beach grassland. The base class for the gravel during the 1989-1999 production of sodium dichromate, because of poor management, pollution control facilities is not put into use and other factors, a large number of high concentrations of Cr6 + production of waste water, part of the mother liquor straight xenophobic environment; temporary heap residue field, the bankruptcy of discarded industrial plant of chromium raw materials and the production of waste retained in the plant by leaching,<a href="http://www.oakleysunglassess.net/" target="_blank" class="postlink">Oakley Sunglasses</a>, seepage, etc. easily into groundwater, as groundwater area depth for the 0-9.5 m, sand and gravel to form the impermeable layer distribution layer without very vulnerable to groundwater pollution, groundwater containing Cr6 + compounds with the flow of Shandong west, away from the plant at around 0.8 km west of the formation of Springs (mainly A spring-based) leaking through the swamp about to 12.7x 104 m3 / d of the flow channels and Halle jianhe row Runie Hai. Years of monitoring the spring shows, spring water exceeded the average in Cr6 + more than 900 times, into the surface water has become a major source of pollution. We according to production process and possible ways of pollution emissions from the plant balance of Cr6 + were measured, the results show is now stranded in the Golden & Silver Sands aquifer C T'6 + was about 978.61 t. The survey also revealed that the region between groundwater and surface water are closely related, and Halle jianhe upstream tributary of the Yellow Line is the source of water; Halle jianhe the East River Reservoir is a large beach drinking water, industrial and agricultural important source of water; Nirvana duo downstream water right for the water source is the main source of water supply in Xining City, is one of environmental sensitive areas are on the water are higher, and are in need of special protection areas. Water in the canal Niehai Halle jianhe of the Cr6 + concentration 0.188 mg / L, while the irrigation of farmland, crops, irrigation area and irrigation area of ​​ecological groups of pollution should not be ignored. The original chemical left in the environment of Qinghai Haibei containing Cr6 + in a large number of pollutants that the water flowing through these regions Nirvana Nirvana River and water sources of water pollution. <br /> 2 Results and discussion <br /> 1.2 Cr6 + monitoring methods <br /> Huangshui as a tributary of the Yellow River is the eastern part of Qinghai Province, one of the main rivers. Since 1996, environmental protection, water conservancy and other departments in the Line section of the detection of water more than hexavalent chromium Cr6 +, part of the time the concentration exceeded the national surface water environmental quality standards. Xining duo in 2003 it has detected within the water source wells C r6 +.
