我國(guó)土壤環(huán)境狀況總體不容樂觀,部分地區(qū)土壤污染較重,耕地土壤環(huán)境質(zhì)量堪憂,工礦業(yè)廢棄地土壤環(huán)境問題突出。下一步,應(yīng)從完善土壤污染防治政策法規(guī)標(biāo)準(zhǔn)等方面進(jìn)一步加強(qiáng)土壤污染防治工作。

在加快完善土壤污染防治政策法規(guī)標(biāo)準(zhǔn)方面應(yīng)盡快修訂《土壤環(huán)境質(zhì)量標(biāo)準(zhǔn)》等相關(guān)標(biāo)準(zhǔn),制訂主要污染物分析測(cè)試方法、土壤標(biāo)準(zhǔn)樣品等標(biāo)準(zhǔn),,以不斷完善土壤環(huán)境保護(hù)標(biāo)準(zhǔn)體系,滿足土壤環(huán)境監(jiān)管工作的需要。

土壤中的總石油烴是土壤檢測(cè)的重要指標(biāo)，目前國(guó)家還沒有制定統(tǒng)一的監(jiān)測(cè)分析方法，國(guó)際國(guó)內(nèi)對(duì)于土壤中的總石油烴特別是土壤中沸點(diǎn)較高（170℃-430℃）、碳數(shù)在c10-c35的石油烴類的標(biāo)準(zhǔn)方法及文獻(xiàn)均為紅外分光光度法為主，國(guó)內(nèi)暫行方法采用國(guó)家環(huán)?？偩志幹频摹度珖?guó)土壤污染狀況調(diào)查樣品分析測(cè)試技術(shù)規(guī)定》里的紅外分光光度法測(cè)定。這種方法靈敏度低；有機(jī)溶劑使用量大，分析過程中容易產(chǎn)生誤差，影響測(cè)定數(shù)據(jù)的準(zhǔn)確性。如何使測(cè)量精確及準(zhǔn)確是石油烴總量測(cè)定中需要解決的問題。

The overall situation of soil environment in my country is not optimistic. Some areas have serious soil pollution, the quality of cultivated land soil environment is worrying, and the soil environment problems of industrial and mining wasteland are prominent. In the next step, soil pollution prevention and control work should be further strengthened from the aspects of improving soil pollution prevention and control policies, regulations and standards.

In terms of speeding up the improvement of soil pollution prevention and control policies, regulations and standards, relevant standards such as "Soil Environmental Quality Standards" should be revised as soon as possible, and standards such as analysis and testing methods for major pollutants, soil standard samples should be formulated, so as to continuously improve the soil environmental protection standard system and meet the requirements of soil environmental protection. regulatory needs.

The total petroleum hydrocarbons in the soil is an important indicator for soil testing. At present, the country has not formulated a unified monitoring and analysis method. The international and domestic concerns about the total petroleum hydrocarbons in the soil, especially the high boiling point (170℃-430℃) and carbon number in the soil. The standard methods and literatures of petroleum hydrocarbons in c10-c35 are mainly infrared spectrophotometry. The domestic temporary method adopts the infrared spectrophotometry in the "National Soil Pollution Status Survey Sample Analysis and Testing Technical Regulations" compiled by the State Environmental Protection Administration. . The sensitivity of this method is low; the amount of organic solvent used is large, and errors are prone to occur during the analysis process, which affects the accuracy of the measured data. How to make the measurement precise and accurate is a problem that needs to be solved in the determination of the total amount of petroleum hydrocarbons.



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a deactivated capillary empty column to determine the content of total petroleum hydrocarbons in soil, and the area normalization method was used for quantification, and the results were accurate and reliable.
