Abstract:
Eight paired organophosphate diesters (Di-OPs) and organophosphate triesters (Tri-OPs) were investigated in wipes from analytical instruments and 47 material samples related to household products, including textiles, electrical/electronic devices, building/ decoration materials and children\'s products. The total concentrations of Di-OPs ranged in 3577-95551 ng/m2 in the wipes and limit of detection-23002 ng/g in the materials. The Tri-OPs concentrations varied significantly in the ranges of 107218-1756892 ng/m2 and 2.13-503149 ng/g, respectively. Four industrial Di-OPs were detected in > 65% of the studied samples suggesting their direct application in the studied materials. Furthermore, we demonstrated for the first time that four non-industrial Di-OPs, e.g., bis(2-chloroethyl) phosphate, bis(1-chloro-2-propyl) phosphate, bis(1,3-dichloro-2-propyl) phosphate, and bis(butoxyethyl) phosphate, identified as degradation products of their respective Tri-OPs were also detected in these studied samples, which might act as important emission sources of Di-OPs in indoor environments. We estimated the burden of Di-OPs and Tri-OPs in a typical residential house and instrumental room, which both exhibited important contributions from furniture, building and decoration materials, and electrical/electronic devices. Limit health risk was posed to local people via air inhalation.
摘要:
在分析仪器的湿巾和与家用产品相关的47个材料样品中,研究了八成对的有机磷酸酯二酯(Di-OP)和有机磷酸酯(Tri-OP),包括纺织品,电气/电子设备,建筑/装饰材料和儿童产品。湿巾中Di-OP的总浓度范围为3577-95551ng/m2,材料中的检出限为23002ng/g。Tri-OPs浓度在107218-1756892ng/m2和2.13-503149ng/g的范围内显着变化,分别。在>65%的研究样品中检测到四种工业Di-OP,表明它们直接应用于研究材料中。此外,我们首次证明了四种非工业Di-OPs,例如,双(2-氯乙基)磷酸酯,双(1-氯-2-丙基)磷酸酯,双(1,3-二氯-2-丙基)磷酸酯,和双(丁氧基乙基)磷酸酯,在这些研究样品中也检测到了它们各自的Tri-OPs的降解产物,这可能是室内环境中Di-OPs的重要排放源。我们估计了典型住宅和乐器室中Di-OP和Tri-OP的负担,两者都表现出家具的重要贡献,建筑和装饰材料,和电气/电子设备。通过吸入空气对当地人造成了有限的健康风险。
