Soil and sediment collected in the vicinity of an open electronic waste disposal and recycling facility located in Guiyu, Guangdong, China, were analyzed for the levels of common polybrominated diphenyl ethers (PBDEs) by using soxhlet extraction and gas chromatography/mass spectrometry. The PBDEs were detected in the soil and sediment samples at levels of 0.26-824 ng/g (dry weight). The obtained isomer profiles of PBDEs from the two soil samples collected from different contamination sites were found to be similar to various technical formulations of fire retardant products.
对在中国广东贵屿一个露天电子垃圾处理与回收设施附近采集的土壤和沉积物样本，采用索氏提取法和气相色谱/质谱联用仪分析了其中常见多溴二苯醚（PBDEs）的含量。在土壤和沉积物样本中检测到的PBDEs含量为0.26 - 824纳克/克（干重）。从不同污染地点采集的两个土壤样本中获得的PBDEs异构体分布情况，与各种阻燃产品的工业配方相似。
