Abstract

The effect of the endocrine disruptor nonylphenol on the biological activity of loamy soddy-podzolic soil (Eutric Albic Retisol (Abruptic, Loamic, Aric, Ochric)) was studied in model experiments. The upper horizons of loamy soddy-podzolic soil sampled in Leningrad oblast were the object of this study. The number of soil microorganisms, the activity of soil enzymes, and soil respiration were determined with the methods commonly used in soil microbiology and biochemistry. The content of nonylphenol in soil samples was determined using high-performance liquid chromatography. Soil contamination with nonylphenol was shown to cause time- and dose-dependent changes in the activity of the pool of nitrogen, carbohydrates, and redox enzymes and increases the basal respiration. The results obtained are an important stage necessary for risk assessment of soil contamination with alkylphenols, and can be used in the development of a remediation methodology for soils contaminated with endocrine disruptors.

壬基酚对壤土水润土壤生物活性的影响

摘要

在模型实验中研究了内分泌干扰物壬基酚对壤土质肥沃土壤的生物活性的影响（Eutric Albic Retisol（Abruptic，Loamic，Aric，Ochric））。这项研究的目的是在列宁格勒州采样的壤土质肥沃的土壤上层。用土壤微生物学和生物化学中常用的方法确定土壤微生物的数量，土壤酶的活性和土壤呼吸。使用高效液相色谱法测定土壤样品中壬基酚的含量。结果表明，壬基酚对土壤的污染会导致氮，碳水化合物和氧化还原酶库的活性随时间和剂量变化，并增加基础呼吸。
