Newly discovered bis-(2-ethylhexyl)-phenyl phosphate (BEHPP) was a ubiquitous contaminant in surface soils from a typical region, South China

Establishment of a Target, Suspect, and Functional Group-Dependent Screening Strategy for Organophosphate Esters (OPEs): “Into the Unknown” of OPEs in the Sediment of Taihu Lake, China

“…BEHPP is a novel OPE and has been detected in indoor dust 22 and surface soil. 52 Thus, its distribution characteristics in different environmental media as well as its exposure risk should be interpreted. In addition to biological transformation processing, meta-OH-TPHP is likely to have industrial sources, and the presence of meta-OH-TPHP in indoor dust and sediment samples indicates a more extensive distribution and potential biological exposure of this toxic substance.…”

“…Among them, BEHPP and meta -OH-TPHP deserve specific attention. BEHPP is a novel OPE and has been detected in indoor dust and surface soil . Thus, its distribution characteristics in different environmental media as well as its exposure risk should be interpreted.…”

High-Resolution Mass Spectrometry Screening of Emerging Organophosphate Esters (OPEs) in Wild Fish: Occurrence, Species-Specific Difference, and Tissue-Specific Distribution

“…Beyond the above well-known OPEs, some emerging OPEs have been recently discovered in consumer products or in the environment. − For example, bis-(2-ethylhexyl)-phenyl phosphate (BEHPP) was identified in indoor dust collected from Nanjing city in China for the first time, following its widespread presence in sediment, surface soil, and indoor dust in China. ,,, Two new aryl-OPEs including 2-biphenylol diphenyl phosphate (BPDPP) and tris­(2-biphenyl) phosphate (TBPP) were identified in smartphones, and subsequently, TBPP and BPDPP isomers were detected in indoor dust and soil from China. ,, An abundant and ubiquitous OPE, namely, tris­(2,4-di- tert -butylphenyl) phosphate (TDtBPP), was continuously found in various environment media such as office, home, and e-waste dismantling facility, sediment, water, and atmosphere. ,− ,, This analysis delivers two insights: (a) the prevalence of emerging OPEs in the environment indicates the underestimation of ecological risk of aquatic organisms in most previous studies, which have generally focused on traditional OPEs; and (b) the monitoring list of OPEs is continuing to be expanded. Unfortunately, current chemical regulations do not call for a similar level of scrutiny of the emerging OPEs as of well-known OPEs.…”
