On April 7, 2020, Hammel, Stephanie C.; Hoffman, Kate; Phillips, Allison L.; Levasseur, Jessica L.; Lorenzo, Amelia M.; Webster, Thomas F.; Stapleton, Heather M. published an article.Synthetic Route of 3319-31-1 The title of the article was Comparing the Use of Silicone Wristbands, Hand Wipes, And Dust to Evaluate Children’s Exposure to Flame Retardants and Plasticizers. And the article contained the following:
Organophosphate esters (OPE) are used as flame retardant additives, and along with phthalates, are also used as consumer product plasticizers. As such, human exposure is common and chronic. Deployed as personal passive samplers, silicone wristbands have been shown to detect >1000 industrial and consumer product chems.; however, few studies have evaluated chem. concentrations with their corresponding biomarkers of exposure, particularly in children. Little is known about how well wristbands predict individual exposure vs. existing validated external exposure tools, e.g., indoor air, dust, and hand wipes. The authors analyzed wristbands worn by children (ages 3-6) for 18 OPE and 10 phthalates and compared them to corresponding urinary biomarkers. In total, 13 of 18 OPE and all phthalates were detected in >80% of wristbands; six OPE and four phthalates were significantly associated with corresponding urinary metabolites (rs = 0.2-0.6; p <0.05). When compared to paired hand wipes and house dust, wristbands had similar or greater correlation coefficients with resp. urinary biomarkers. Results suggested wristbands can serve as effective, quant. assessment tools to evaluate personal exposure to some OPE and phthalates, and for certain chems., may provide a better exposure estimate than indoor dust. The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Synthetic Route of 3319-31-1
