土壤中挥发性有机物分析方法研究

Analytical method for volatile organic compounds in soil

近年来,随着经济的高速发展,人们对资源的需求不断增大。人们为了谋求经济利益开始破坏生态环境。滥砍滥伐、大量排放废弃物、对矿石过度开采等行为严重改变了土壤本身的化学和物理结构,而这些改变往往是不可逆的。众所周知,土壤的表面具有肥力,是一个可供植物生长的疏松表层,而且这个具有肥力的疏松表层只有2m左右。因此,如果土壤受到污染,就会对农业生产造成严重影响。我国作为人口大国,同时也是粮食出口大国,如果粮食产量具有较大波动,对我国的影响将十分严重。此外,废弃物、放射性物质、化肥以及农药的排放都会对土壤中的营养成分造成影响,进而影响土壤的净化、储水能力。因此,在促进经济发展的同时,我国还要注重对土壤的保护。土壤保护已经是当前环境保护工作的重中之重。基于此,本文通过对大量资料的查阅以及实验分析,总结了几种关于土壤中挥发性有机物的分析方法,以供各位学者参考。

In recent years,with the rapid development of the economy,people's demand for resources has increased.People began to destroy the ecological environment in order to seek economic benefits.Deforestation,large discharges of waste,and excessive mining of ore severely alter the chemical and physical structure of the soil itself,and these changes are often irreversible.It is well known that the surface of the soil is fertile and is a loose surface for plant growth,and this fertile loose surface is only about 2 meters.Therefore,if the soil is contaminated,it will have a serious impact on agricultural production.As a country with a large population and a large country for grain exports,if China's grain output has large fluctuations,its impact on China will be very serious.In addition,the discharge of waste,radioactive materials,fertilizers and pesticides will affect the nutrients in the soil,which will affect the ability of soil purification and water storage.Therefore,while promoting economic development,China must also pay attention to the protection of the soil.Soil protection has become the top priority of current environmental protection work.Based on this,this paper summarizes several methods for the analysis of volatile organic compounds in soil through the review of a large amount of data and experimental analysis,for the reference of scholars.
