摘　　要：对黑龙江土壤样品中的壬基酚(NP)、壬基酚一氧乙烯醚(NP1EO)和壬基酚二氧乙烯醚(NP2EO)的残留状况开展研究。结果表明,NP、NP1EO和NP2EO均有不同程度的检出,检出率在68.46%~95.38%之间;NP、NP1EO和NP2EO的浓度分别为ND^156.8μg kg-1、ND^15.70μg kg-1和ND^13.63μg kg-1,均值分别为22.02μg kg-1、4.04μg kg-1和2.15μg kg-1;进一步分析,已检出的样品中,NP在0~10μg kg-1的比重最大,NP1EO在4~6μg kg-1比重最大,NP2EO在1~2μg kg-1比重最大。NP的残留水平高于NP1EO和NP2EO,说明NP相对较难降解,更易在土壤中累积。The residual state of Nonylphenol（NP）,nonylphenol monoethoxylate（NP1EO） and nonylphenol diethoxylates（NP2EO） in agricultural soil samples in Heilongjing Province were investigated.It is showed that NP,NP1EO and NP2EO were detected in different contents,with the relevance ratio between 68.46% and 95.38%.NP,NP1EO and NP2EO concentrations were ND-156.8 μg kg-1,ND-15.70 μg kg-1 and ND-13.63 μg kg-1,with the mean of 22.02 μg kg-1,4.04 μg kg-1 and 2.15 μg kg-1,respectively.Further analysis,NP at 0-10 μg kg-1 was the largest proportion,while NP1EO and NP2EO were 4-6 μg kg-1 and 1-2 μg kg-1,respectively.The residue level of NP was higher than those of NP1EO and NP2EO,which implied that the degradation of NP was relatively difficult and easily accumulated in soil.
