Abstract

The invention is applicable to the technical field of environmental safety monitoring, and discloses a method for determination of 55 volatile organic pollutants in soil, and the method comprises the following steps: sample pretreatment, preparation of a to-be-tested solution, setting of parameters, establishment of a standard curve and internal standard method determination. According to the method for determination of the 55 volatile organic pollutants in the soil, a soil sample with a certain amount is extracted with methanol, a matrix correction fluid is added, after headspace treatment, a gas chromatography-mass spectrometry method is used for qualitative and quantitative analysis of the 55 volatile organic pollutants in a soil sample, the method has the advantages of simple operation, high accuracy, high sensitivity, less interference and good repeatability, in a concentration range of 40-800 mug / L, the curve linearity of the 55 volatile organic pollutants is good, correlation coefficients all are above 0.999, and the method has strong practicability for monitoring of the volatile organic pollutants in the soil, can be used for risk assessment of the pollution status of the soil.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of environmental safety monitoring, in particular to a method for measuring 55 kinds of volatile organic pollutants in soil. [0003] 【Background technique】 [0004] Soil organic pollutants can be directly ingested by the human body, and may even accumulate in the body, affecting the biochemical and physiological reactions of the human body, thereby affecting metabolism, development and reproductive functions, and may also affect the level of human intellectual development and damage the nervous system and endocrine system. Organic pollutants in the human body may promote the growth of tumors and increase the incidence of cancer. Soil organic pollutants can directly destroy the normal function of the soil, and can be absorbed by plants and accumulated in the food chain, thereby endangering human health. Soil organic pollutants affect the metabolism and genetic characteristics of soil animals and the...
