Photocatalytic Removal

Bisphenol A (BPA) produced from biomass is a typical endocrine disrupting compound that is carcinogenic and genotoxic and can be accumulated in water due to its extensive use and difficult degradation. In this study, the porous ZnO photocatalyst with core-shell structure and large surface area was successfully developed for the efficient photocatalytic degradation of BPA. The various effects of calcination temperatures, BPA concentrations, ZnO dosages, pH and inorganic ions on the degradation performance were systemically studied. The results showed that 99% degradation of BPA was achieved in 1 h using the porous ZnO calcined at 550°C under the conditions of 30 mg/L BPA, 1 g/L ZnO, and pH of 6.5. Besides, the inhibition effects of anions for the photocatalytic removal of BPA decreased in the order of H2PO4- > HCO3- > SO42- > Cl−, while the cations K+, Ca2+, and Na+ had little effect on the photocatalytic degradation of BPA. The results of scavenging experiments showed that h+, ·O2-, and e− played the key role in the photocatalytic degradation process. Finally, the main pathways of BPA degradation were proposed based on ten intermediates found in the degradation process. This work may provide a good guideline to degrade various endocrine disrupting compounds in wastewater treatment.

Dibutyl phthalate (DBP), an accepted environmental endocrine disrupting compound, which has anti-androgenic effects,is widely used in many industries such as plastics, pharmaceuticals, plastic food packaging materials. This article intends to study the effect on JNK/MAPK pathways in the damage of rat testicle sertoli cells induced by DBP via vitro test. Testicular sertoli cells of rates were incubated by medium containing DBP in different concentrations (0μg/ml,1μg/ml,10μg/ml, 100μg/ml). after culturing for 24 hours the expression of vimentin was detected by immunofluorescence; the expression of vimentin mRNA detected by RT-PCR; Western blot analyzed the expression of related protein of JNK/MAPK pathways in sertoli cells. The results showed that vimentin highly express in sertoli cells and gradually decrease with the increase of poisonous doses. The mRNA expression of vimentin in each exposure group has a downtrend with the increase of does. The total protein of JNK and P-JNK protein increased gradually in a dose effect manner. These results suggested that DBP can decrease the expression of vimentin mRNA, the decrease of which was regulated by JNK/MAPK signal transduction pathway that activated by DBP, and then induced the apoptosis of Sertoli cell.
