Abstract Bisphenol-S (BS) has recently raised public concerns for its adverse effect on the health safety and ecological security. BS concentrations were detected in many water resources, ranging from 10 ng L −1 to 300 μg , so that various purification techniques have been sought remove BS. This study investigated performance of ozonation ferrate oxidation degradation since they are both promis...

1 environmental advocates, regulatory agencies and the mainstream press have given much attention to the possible harm to health posed by bisphenol A. Bisphenol A is one of the most manufactured chemicals worldwide — more than three million tonnes of it are produced each year — and human exposure throughout the developed world is thought to be ubiquitous. Because bisphenol A has estrogenic prop...

Epoxide-amine oligo-adducts were synthesized via a one-pot microwave assisted heterogeneous catalytic transfer hydrogenation. Accordingly, 4-nitroanisole was reduced under microwave conditions to give 4-aminoanisole which reacted immediately with the diglycidyl ether of bisphenol A in an addition polymerization reaction to yield oligo(amino alcohol)s. The hydroxy groups of the new formed oligom...

This study examined the biodegradation potential of three wastewater micropollutants (triclosan, bisphenol A, and ibuprofen) by Nitrosomonas europaea and mixed ammonia-oxidizing bacteria in nitrifying activated sludge. N. europaea could degrade triclosan and bisphenol A, but not ibuprofen. The degradation was observed only in the absence of allylthiourea (an inhibitor for ammonia monooxygenase ...

The vulnerability of developing brains to environmental chemicals has been reported. Here, we examined the temporal effects of bisphenol A on dopaminergic neurons. Exposure of 5-day-old rats to bisphenol A caused hyperactivity in juveniles, after which spontaneous motor activity leveled off at 8 weeks of age, when apoptotic cell death was still observed along with the loss of tyrosine hydroxyla...

BACKGROUND Associations of bisphenol A and phthalates with chronic disease health outcomes are increasingly being investigated in epidemiologic studies. The majority of previous studies of within-person variability in urinary bisphenol A and phthalate metabolite concentrations have focused on reproducibility over short time periods. Long-term reproducibility data are needed to assess the potent...

A highly sensitive and selective method for simultaneous determination of some hydroxyl group-containing endocrine disruptors, including bisphenol A (BPA), bisphenol B (BPB), bisphenol E (BPE), bisphenol F (BPF) and 4-nonylphenol (4-NP), was developed. The method consists of precolumn derivatization of the analytes, solid-phase extraction (SPE) and subsequent chromatographic analysis by high-pe...

The current study includes the screening of indigenous extracellular laccase producing fungus from the soil, identified as Phanerochaete chrysosporiumspecies.The selected strain was applied under the optimized condition for the production of  laccase in the solid state fermentation. The effect of polyethylene glycol and Triton X-100 on the enhancement of enzyme activity and bi...
