Despite high production and usage of bisphenols including bisphenol A (BPA) as well as bisphenol A diglycidyl ether and its derivatives (BADGEs), little is known about the occurrence and fate of these substances in wastewater treatment plants (WWTPs) in the U.S. In this study, we investigated the occurrence, removal, mass flows, and fate of eight bisphenol analogues and six BADGEs based on the concentrations measured in influent, primary effluent, final effluent, and sludge from two WWTPs (WWTPA and WWTPB) in the Albany area of New York State, USA. BPA, bisphenol F, bisphenol S, and BADGE·2H2O were the predominant compounds found in influents of both WWTPs, at respective geometric mean (GM) concentrations of 90.0, 90.2, 31.2, and 6.48 ng/L in WWTPA, and 53.3

Bisphenol A (BPA) is a widely present endocrine disruptor chemical found in many household items. Moreover, this chemical can bioaccumulate in various terrestrial and aquatic sources; thereby ensuring continual exposure of animals and humans. For most species, including humans, diet is considered the primary route of exposure. However, there has been little investigation whether commercial-brands of dog foods contain BPA and potential health ramifications of BPA-dietary exposure in dogs. We sought to determine BPA content within dog food, whether short-term consumption of these diets increases serum concentrations of BPA, and potential health consequences, as assessed by potential hematological, serum chemistry, cortisol, DNA methylation, and gut microbiome changes, in dogs associated with short-term dietary exposure to BPA. Fourteen healthy privately-owned dogs were used in this study. Blood and fecal samples were collected prior to dogs being placed for two-weeks on one of two diets (with one considered to be BPA-free), and blood and fecal samples were collected again. Serum/plasma samples were analyzed for chemistry and hematology profiles, cortisol concentrations, 5-methylcytosine in lymphocytes, and total BPA concentrations. Fecal samples were used for microbiome assessments. Both diets contained BPA, and after two-weeks of being on either diet, dogs had a significant increase in circulating BPA concentrations (pre-samples=0.7±0.15ng/mL, post-samples=2.2±0.15ng/mL, p

Benzophenone-3 (BP-3) is a widespread environmental contaminant and an estrogenic compound. Very little is known with regard to the occurrence in indoor air and the inhalation exposure of humans to BP-3. In this study, 81 indoor air samples were collected from various locations in Albany, New York, USA, in 2014 and analyzed for BP-3 by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). BP-3 was found in all indoor air samples and the overall concentrations in bulk air (vapor plus particulate phases) were in the range of 0.19-72.0 ng/m(3) (geometric mean: 2.67 ng/m(3)). The highest concentrations (geometric mean: 10.7 ng/m(3)) were found in cars, followed by barber shops (6.57) ˃ public places (5.75)>homes (3.27) ˃ offices (1.96) ˃ garages (1.04) ˃ laboratories (0.47). The estimated geometric mean daily intake (EDI) of BP-3 for infants, toddlers, children, teenagers, and adults through indoor air inhalation from homes was 1.83, 1.74, 1.18, 0.69, and 0.51 ng/kg-bw/day, respectively. Although high concentrations of BP-3 were measured in some microenvironments, the estimated contribution of indoor air to total BP-3 intake was
