摘要

Phthalate esters (PEs) are aboundant chemicals which were commonly used as plasticizer, especially in the manufacture of poly(vinyl chloride) (PVC). Now PEs have been a kind of ubiquitous contaminants in the biosphere and have been found world-wide in atmosphere[l], water[2], soil[3] and biota[4]. Although most PEs have a very low accute toxicity, it is reported that chronic exposure to some PEs, such as di-(2-ethylhexyl)phthalate (DEHP), could cause liver cancer in rats and mice and decrease human platelet function[5]. So more attetion has been paid to analysis of PEs in biota samples. This paper developed a procedure for the analysis of phthalate esters (PEs) in biota samples by use of TLC and HPLC. It was found that the average recoveries for various PEs standards were between 92.3% and 98.1% with standard deviations of 3.9% to 5.6%. The method was successfully used to separate and determine PEs in some plant samples. The uptake of PEs by plants from soil were also investigated.
