Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

ABSTRACT: There is growing evidence that aryl organophosphate flame retardants
14
(aryl-OPFRs) can disrupt lipid metabolism in animals. However, epidemiologic studies of this
15
possible phenomenon are lacking. In this study, we explored the association between urinary
16
concentrations of three aryl-OPFRs (triphenyl phosphate (TPHP), tricresyl phosphate, and
17
2-ethylhexyl diphenyl phosphate (EHDPP)) metabolites and plasma levels of triglyceride (TG)
18
and total cholesterol (TC) in 259 general population by comparing with six alkylated and
19
chlorinated OPFRs. Multivariate linear regression analyses clarified that the log-transformed
20
TC levels appeared to increase linearly across the quartiles of 5-OH-EHDPP (p trend
