Analysis of Phthalic Acid Esters in Soil and Peanut from Guangdong Province

Abstract:

This study investigated the contents of 5 phthalic acid esters in the soil and peanut from Ningxi and Huazhou farms. 5 PAEs were detected by gas chromatography coupled with mass spectrometry (GC-MS) in soil and peanut. The soil background concentrations of PAEs ranged from 0.438 to 1.624 mg/kg in Ningxi and that range in Huazhou was from 0.468 to 1.235 mg/kg. The results showed that BBP and DEHP were both the major PAEs, and DEHP was the major PAEs of both sites. PAEs in the soil of two sites were contaminated slightly. The PAEs contents in peanut kernels ranged from 2.466 to 8.888 mg/kg and 3.436 to 5.594 mg/kg, respectively. Results show that the order of PAEs concentration of peanut in the both sites was: root > stem > leave > shell.
