In recent years,the number of heavy metal pollution accidents. According to the “China Youth Daily”A Chongqing business relocation legacy in soil purification. According to “Daily” ChengduHechi cadmium pollution occurs everywhere the slag pile. Reporter Liu Yanmin photoFrom last year’s CD rice crisis,Qujing chrome pollution incident to early this year Guangxi Longjiang cadmium pollution,a pollution incident in the periodic table of elements to some obscure heavy metal elements into the common people’s field of vision,we usually eat the agricultural products have not been subjected to heavy metal pollution? Heavy metal contaminated soil at tens of millions of dollars in fees after the undertake by who? Hunan has successfully solved a uranium mine farmland pollution problem of Qingdao Agricultural University professor Wang Kairong when accepted newspaper reporter when the interview disclosed,these problems,the country has begun to control,the first national soil pollution investigation report is expected to release in the two quarter,concern about soil pollution prevention law would also be in”Twelfth Five-Year Plan”During the issue.Recommended readingChina’s rich list ranked second in Karamay City beyond the Erdos (group of pictures) The European Union brewing a carbon tax levyJordan Jordan sport claims to tens of millions ofThe world bank said China must deeply reformDeath church denies bile bears prior injection of anestheticsThe Chinese model of income (group of pictures) Compete [God] Trading King surfacedZhao Xiao: the United States the move surprised me. Investigation Qingdao farmland security experts have the veinsQingdao Agricultural University professor Wang Kairong points out,the whole of China is now 20% of farmland pollution; last year,this year’s Longjiang crisis cadmium rice cadmium pollution incident,make people pay more attention to the “heavy metal pollution.”. Heavy metal pollution is caused by what? Qingdao farmland have been heavy metal pollution? Qingdao agricultural experts scholars have already begun to address these problems by investigation and study. Only part of the land of cadmium pollution exceed the standardAccording to the Qingdao Academy of Agricultural Sciences lab director,senior agronomist Chen Jianmei introduced,general farmland heavy metal pollution for two reasons: around the farm chemical plant waste water waste,or improper fertilization farmland once,leading to organic fertilizer in soil heavy metal content in residue.Chen Jianmei’s Qingdao Academy of Agricultural Sciences in 2010 to Qingdao city vegetable planting relatively centralized area soil heavy metal contents were investigated and analyzed,the last survey,Qingdao city soil quality basic safety. “Laixi,Jimo,Shandong and other monitoring points of comprehensive pollution index of soil are in a clean and safe state,suitable for planting vegetables. But Laixi and Jimo have 4 monitoring point samples of soil heavy metal cadmium content exceed the standard,and the pollution is mainly concentrated in the surface soil.” Chen Jianmei told the reporters,in fact,Qingdao’s heavy metal pollution of farmland in the country is not serious,because there is no obvious source of pollution. Winter vegetables with tieQingdao University of Science & Technology,College of environmental and safety engineering professor Qian Yi had also conducted a similar survey,he according to different land use types in Qingdao city is divided into five functional areas: industrial areas,commercial areas,residential areas,agricultural areas and tourist areas,findings shows,cadmium (Cd) in each function area content were higher than the national soil environmental quality standard of two,other heavy metals such as chromium (Cr),copper (Cu),nickel (Ni),lead (Pb),zinc (Zn) concentration were lower than the standard of two countries.Professor Qian Yi of Qingdao two important vegetable wholesale market of 24 kinds of common vegetables in season for sample testing,the results show that the Qingdao city winter vegetable heavy metal pollution is serious and spring vegetables,to lead (Pb),cadmium (Cd) pollution; Allium lead (Pb),cadmium (Cd) with high content of garlic,which is moderately polluted. Fortunately,health risk assessment in vegetable in Qingdao city last show,Pb,Cd content without significant risk to public health. Residential area more pollution due to battery”Cadmium distribution in nature is not extensive,cadmium in the soil comes mainly from zinc ore,lead-zinc smelting,alloy,electroplating,chemical plants and other waste water,industrial waste piles and chemical fertilizers and pesticides (phosphate fertilizer,compound fertilizer) abuse etc..” Qian Yi explained,his investigation of choice function area is polluted for a long time representative District,such as iron and steel industry,alkali,cement manufacturing enterprises in the industrial zone.Residential area is also possible because the battery life garbage pollution. “Living supplies most of the heavy metal pollution source,the coal particles,coating,paint also contain heavy metals,which can lead to the surface of the soil heavy metal content will be high.” Easy to stain decontaminationRely on plants to “Detox” takes seven or eight yearsSince 2009,China has more than 30 heavy metals pollution,seriously affecting people’s health,government sector and academia also countermeasures,hoping to purify the polluted farmland,can reduce the loss to the minimum. However,soil remediation spend hundreds of thousands of yuan,who is responsible for the repair,and who pay wait for a problem,perplexing government departments at all levels. Peanut soybean easy “eat” heavy metalWang Kairong told the reporters,the heavy metals pollution in soil is easy to enable the plant to the heavy metal content in exceed the standard,especially for containing protein of higher plants,such as soybean,peanut,cabbage and so on,are most vulnerable to heavy metal pollution in the invasion,and different varieties of plants to absorb heavy metals are not the same.Qingdao Academy of Agricultural Sciences senior agronomist Chen Jianmei confirmed to reporters,the peanut exports have been checking out the heavy metal exceed the standard,this also makes a lot of experts begin to study the absorption of heavy metal content of less variety.Uptake of heavy metals by differences in different rice varieties,who also reflects the very clear. Nanjing Agricultural University professor Pan Genxing’s team have done an experiment,found in hybrid rice,super rice cadmium exceed the standard risk for more severe than ordinary rice. Experts gathered planting rice in south of two kinds of soil,and in part to deliberately added cadmium in the soil,the experts found that,without cadmium in the soil,super rice on cadmium affinity is conventional rice 2.4 times,its grain cadmium content is more than 1 times the ordinary hybrid rice. Pan Genxing explained,that exceed the standard of super rice cadmium pollution is more serious,because it is a developed root system,on CD in soil with stronger absorption capacity. Kind mulberry sericiculture cleanse the landCrop heavy metal exceed the standard make people plagued,but also for the farmland soil pollution control to provide a train of thought. “Soil pollution remediation technology including soil washing,chemical oxidation,phytoremediation,generally speaking,the farmland in the remediation of heavy metal phytoremediation,long working cycle,and want to completely clean up the soil is not possible.” Wang Kairong himself in a uranium mine in Hunan farmland pollution remediation for example,”the repair work on 90 time begin the century did,before and after about seven or eight years of time to complete.”Then Hunan of cadmium pollution in the farmland is how to manage? The answer is a species of mulberry. Wang Kairong has discussed in detail the mulberry in the treatment of cadmium pollution in terms of efficacy: by using silkworm production mode to replace grain production mode,put an end to the sewage irrigation,eliminates the risk from cadmium in food chain,so that the soil productivity was restored,farmland than rice mode and improve the average annual output value of 2880 yuan / ha,than corn rises 8880 yuan / hectare,profit tax increased by 1980 yuan / ha,soil cadmium content of annual average decline in 1.33mg / kg. “Kind of mulberry sericiculture is management and use of Cd pollution in a successful economic ecological models,more patterns to be explored further.”However,seven or eight years is a long period,there is no efficient method? If the use of physical and chemical methods for repair of farmland soil pollution,can shorten the cycle,but hundreds of millions of dollars is a problem. “Therefore,the rapid restoration of farmland pollution,is technically feasible,but not economically feasible.” Wang Kairong said. Industrial land to “disinfection”By comparison,in recent years the city industrial land soil remediation the outcome of the case more. The relocation of factories,legacy land is likely to take the lead by the government to introduce environmental protection company soil restoration,but the costs in the hundreds of millions of.Qingdao new world of environmental remediation company limited marketing directorWu TaoBeing busy for a chemical plant remediation of soil preparation,due to the chemical factory production sector has gradually moved to other places,local governments hope to use this space to create a newIndustryPark,but before this,the land must first “disinfection”. “In March,we will to the chemical plant pollution status were investigated in more detail,such as the type of soil pollution,heavy metal concentration,whether pollution to groundwater and so on,and then reported to the government,the government submitted to the project,you can start the restoration project approval.” In February 16th,in the new world of the office,the relevant responsible person of the company Wu Tao briefed reporters on the soil remediation general process.According to Wu Tao,the city removed the chemical plant,printing plant,pesticide factory,electroplating plants and other plots are most easily legacy. “Such as the printing of the chromium slag,electroplating factory of cadmium in sewage discharge.” The huge costs paid by whoNew world of environmental remediation company limited,Shandong province is the first in the soil remediation of the professional company,according to the relevant person in charge,the industry perspective,soil remediation is a huge market. “In general,soil remediation cost time all is in 10 million yuan level,only taking Beijing as an example,some of the relocation of the chemical factory need to repair the land,the market has 300 to 500 hundred million.”High land restoration costs,in our country should undertake by who? Wu Tao told the reporters,in general,currently on the market of land remediation projects in industrial land mostly,development of higher value,but because at present many of the remaining enterprises land was once state-owned chemical enterprises,these enterprises a property conversion or even bankruptcy,so the land restoration subject but also from countries lead the way,”repair fund supported by the government,if the future commercial development,so its beneficiaries can also participate in.”Author / journalist Li Yang Latest news Soil heavy metal pollution investigation is expected to hard bakedJuly 18,2006,the State Environmental Protection Administration andThe Ministry of land and resourcesUnited started the budget of 1000000000 yuan of the first national soil pollution investigation,according to the plan,2008 is the survey summary stage,the main task is to prepare the investigation report,a comprehensive summary and integrated survey results,however,until today,the pollution investigation report the detailed content and not disclosed.According to the Qingdao Agricultural University professor Wang Kairong is disclosed,this report will be in the two quarter of this year. “In fact,this report early in the end of last year has been completed around the data collection work,but some local heavy metal pollution is serious,the relevant departments should check seriously,data is relatively sensitive,so the more cautious.” Wang Kairong explained,this report to seven to 80 reflected at present our country soil pollution,”because this investigation is sampling investigation,isMinistry of environmental protectionLand and resources administration to formulate a general survey plan,commissioned by the following provinces to the environmental protection unit to do,and some provinces may because of financial or method of limits,unreliable survey data,or simply not to investigate,using the original data,thus can not fully reflect the current situation of soil pollution.” Wang Kairong also revealed,soil pollution prevention and control law will be in the “12th Five-Year Plan” launched.Qingdao University of Science & Technology professor Qian Yi also on the soil pollution preventionLawThe introduction of full of confidence. “Early last year,the State Council has officially approved the” heavy metal pollution “Twelfth Five-Year Plan” “(referred to as” planning “),this is our country first introduced the” Twelfth Five-Year Plan “.”Reportedly,”Twelfth Five-Year Plan” period,Shandong will build soil pollution environmental regulation system,to commissariat,vegetable base and other important sensitive area for risk assessment,prohibited the use of heavy pollution soil cultivation,production of agricultural and sideline products. To carry out environmental remediation of contaminated soil,without assessing and harmless control of land shall not undertake is on the move and two times the development of. Plan of levying environmental tax in Jiangxi province is pilotEnvironmental experts according to Ministry of land and resources data estimation,the whole nation is annual because of heavy metal contamination of food high amounts to 12000000 tons,equivalent to Guangdong annual grain total output,can feed 40000000 people resident in the Pearl River delta.In order to curb pollution,industry insiders have suggested that learning some developed countries environmental tax collection practices.Ministry of environmental protectionVice MinisterTensionThe army also has said publicly,on environmental tax issues,Ministry of Finance,Administration of TaxationAnd the Department of the environment has been studied,there has been some basic considerations. It is reported,in 2010 July,the environment tax levy has released a draft,2013 schedule has also been tentatively identified. However,the environment tax would eventually be a still unknown.According to the plan,in the nationwide levy resource tax,the relevant departments in the discussion of agreement,would first select some key city pilot. Reportedly,Jiangxi,Hunan,Hubei and other provinces and cities may become environmental tax pilot. October 17,2011,the State Council issued the “on the strengthening of environmental protection work of key opinion”,put forward clearly to carry out economic policies conducive to environment protection,and actively promote the environmental tax reform,research on Levying Environment Protection tax. This opinion come on stage,means that the environmental tax reform formally on the agenda.Ecological tax environment tax,green tax,is the end of the twentieth Century international tax academic arisen concept. Some developed countries levy environment tax mainly sulfur dioxide tax,the tax on water pollution,noise,solid waste and garbage tax tax tax 5. According to “China Daily”
