Bisphenol F (BPF) and bisphenol S (BPS) are becoming widespread in the environment despite lack of information regarding their fate during wastewater treatment environment. This study assessed biodegradation kinetics BPF BPS biological with activated sludge using GC-MS/MS, identification biotransformation products (BTPs) LC-QTOF-MS. The results showed that degrade readily unlikely accumulate bi...
Bisphenol A (BPA), which is widely used for manufacturing polycarbonate plastics and epoxy resins, has been banned from use in plastic baby bottles because of concerns regarding endocrine disruption. Substances with similar chemical structures have as BPA alternatives; however, limited information available on their toxic effects. In the present study, we reviewed disrupting potential gonad thy...
Bisphenol S Adsorption Behavior on Ferralsol and Biochar Modified Soil with Dissolved Organic Matter
A major cause for dental resin composite restoration replacement is secondary caries attributed to Streptococcus mutans. Salivary esterases were shown to degrade resin composites. Hypothesis: S. mutans contain esterase activities that degrade dental resin composites and adhesives. Esterase activities of S. mutans were measured using synthetic substrates. Standardized specimens of resin composit...
The occurrence of endocrine disrupting chemicals (EDCs) is a major issue for marine and coastal environments in the proximity urban areas. EDCs Pearl River Delta region well documented but specific data related to Macao unavailable. levels bisphenol-A (BPA), estrone (E1), 17α-estradiol (αE2), 17β-estradiol (E2), estriol (E3), 17α-ethynylestradiol (EE2) were measured sediment samples collected a...
