Abstract Although the utilization of pesticides accounted for the group of persistent organic pollutants was banned years ago, a count of pesticides are still directly or indirectly a source of contamination in Europe. One of them, simazine is still allowed for use in the United States. Aim of this experiment was development of soil remediation method which could be utilized for degradation triazine class pesticides – simazine was an example used. A method for soil remediation based on ozonation processes in fluidized bed was successfully utilized for removal of simazine from contaminated soil. For the study soil highly contaminated with simazine up to the concentration of 0.05% w/w was used. Determination of the pesticide levels in soil was performed using extraction and gas chromatography. The method allowed 80% reduction of pesticide concentration level. The degradation of pesticide was accompanied with changes of physicochemical parameters of soil, i.e., decrease of pH and a increase of nitrates concentration. Despite changes in physicochemical properties of the soil, the developed method proved to be highly effective and can be successfully applied on an industrial scale.

一种西玛津污染土壤的修复方法

摘要 虽然在多年前就禁止使用属于持久性有机污染物的农药，但在欧洲，农药的数量仍然是直接或间接的污染源。其中之一，西玛津仍被允许在美国使用。本实验的目的是开发可用于降解三嗪类农药的土壤修复方法——西玛津就是一个例子。一种基于流化床臭氧化过程的土壤修复方法被成功地用于去除污染土壤中的西玛津。对于研究土壤，使用浓度高达 0.05% w/w 的西玛津高度污染。使用萃取和气相色谱法测定土壤中的农药含量。该方法可将农药浓度水平降低 80%。农药的降解伴随着土壤理化参数的变化，即pH值的降低和硝酸盐浓度的增加。尽管土壤的物理化学性质发生了变化，但所开发的方法被证明是非常有效的，并且可以成功地应用于工业规模。
