壬基酚聚氧乙烯醚及其降解产物壬基酚在香蕉和土壤中的消解动态及风险评估
Residue decline study and risk assessment of nonylphenol ethoxylates and its metabolites nonylphenol in banana and soil
摘要
Abstract
Aimed to evaluate the safety and regular use of nonylphenol ethoxylates(NPnEO), residue decline study of NPnEO and its metabolites nonylphenol (NP)in banana and soil were investigated and the samples were analyzed by UPLC-FD in 2009 -2010. The decline curves of NPnEO in banana and soil accorded the first-order kinetics. The half-life of NPnEO turns tobe8.8-12 din banana and 6.9 -8.5 d in soil,its metabolites NP turns to be 16 - 18 d in banana and 24 -26 d in soil. During the harvest period of the banana, the residue of NPnEO and NP in banana are under 0. 01 mg/kg. By calculating,the intakes of NP per man and per day from banana is 0. 09 μg. Risk quotient (RQ) is 0. 003. The residue could be declined to the safety level.关键词
