摘要

There is growing interest in the identification of novel aryl organophosphate triester (OPTE) congeners that may exist in the environment. In this study, we discovered 11 novel aryl OPTEs in north China house dust using a characteristic aryl phosphate fragment-guided high-resolution mass spectrometry method with data-independent acquisition. Tripentylated triphenyl phosphate (TPeTPhP), dicresyl phenyl phosphate (DCrPP), diisodecylphenyl phosphate (DIDPP), butoxyethoxyethyl octyl phenyl phosphate (BEEOPP), dioctyl nonylphenyl phosphate (DONPP), propoxypropyl bis(diphenyl phosphate) (PPBDPhP), octyl nonylphenyl phenyl phosphate (ONPPP), and (saturated mono-oxygen butoxybutyl) butoxyethoxyethyl phenyl phosphate (MBBPP) were detected in 84-100% of 45 samples. ONPPP was present in the highest median concentration of 69.0 ng/g, followed by DONPP (68.7 ng/g), DIDPP (50.3 ng/g), BEEOPP (42.5 ng/g), DCrPP (33.7 ng/g), PPBDPhP (25.0 ng/g), TPeTPhP (9.28 ng/g), and MBBPP (4.80 ng/g). Seven novel aryl OPTEs were also detected in standard house dust SRM2585, and the concentration of DIDPP (4375 ± 660 ng/g) was 4-fold higher than that (1048 ± 44.5 ng/g) of triphenyl phosphate, a typical aryl OPTE. The discovery of these novel OPTEs has significantly enriched our understanding of the aryl OPTEs present in house dust.
