采用开放式（ORS）和半封闭回收（SCRS）两种不同的回收方式，对某多废弃物（电子、塑料和橡胶废弃物以及废弃的家用电器和车辆）回收区收集的土壤和室外沉降尘样品中12种有机磷阻燃剂（OPFRs）的分布进行了测定。在分析的12个opfr中，11个在所有土壤和粉尘样品中检测频率为75%-100%。土壤样品中的Sigma OPFR浓度在ORS （122-2100 ng/g）显著高于SCRS （58.5-316 ng/g）和附近农田（37.7-156 ng/g）。沙尘样品中Sigma OPFR浓度高于土壤样品，其空间分布与土壤相似，从ORS （1390 ~ 42700 ng/g）降至SCRS （914 ~ 7940 ng/g）。三（2-氯异丙基）磷酸（TCIPP）是两种土壤(
Distribution of 12 organophosphate flame retardants (OPFRs) was determined in soil and outdoor settled dust samples collected from a multi-waste (electronic, plastic, and rubber wastes and abandoned household appliances and vehicles) recycling area, that encompassed different modes of operation i.e. open (ORS) and semi-closed recycling (SCRS). Among the twelve OPFRs analyzed, eleven were detected at a frequency of 75%-100% in all soil and dust samples. In soil samples, Sigma OPFR concentrations were significantly higher at ORS (122-2100 ng/g) than at SCRS (58.5-316 ng/g) and nearby farmlands (37.7-156 ng/g). The Sigma OPFR concentrations in dust samples were higher than those in soil samples with spatial distribution similar to that observed for soil, decreasing from ORS (1390-42,700 ng/g) to SCRS (914-7940 ng/g).Tris(2-chloroisopropyl) phosphate (TCIPP) was the major OPFRs in both soil (
