This study investigated the applicability of waste antivirus copper film (CF) as a Fenton-like catalyst. The reaction activity of HO and CF in combination was significantly enhanced by ultrasound (US) irradiation, and the synergy factor calculated from bisphenol A (BPA) degradation using CF-HO-US was 9.64 compare to that of dual factors. Photoluminescence analyses were conducted to compare the generation of hydroxyl radicals during both processes. In this sono-Fenton-like process, BPA degradation was affected by solution pH, temperature, ultrasound power, CF size, HO dose, and initial BPA concentration. The BPA degradation curves showed an induction period (first stage) and a rapid degradation period (second stage). Process efficiency was totally and partially enhanced in the presence of chloride and carbonate ions, respectively. Chemical scavenger tests showed that both free and surface-bound hydroxyl radicals participate in BPA degradation under the sono-Fenton-like process using CF. The functional groups and copper crystals on the CF surface remained unchanged after five consecutive reuses, and the BPA degradation efficiency of CF was maintained over 80% during the reuse processes as a sono-Fenton-like catalyst.

Bisphenol A (BPA) is a widely used industrial compound commonly found in various everyday plastic products. Known for its endocrine-disrupting properties, BPA can enter the human body through multiple pathways. Prenatal exposure to BPA not only disrupts placental structure and function but also interferes with normal steroid metabolism.

Efficient nutrient recovery from source-separated urine is vital for wastewater treatment, with microalgae as a promising solution. However, bisphenol A (BPA) in urine can hinder microalgal resource recovery and pose water quality risks. The role of plant hormones in enhancing microalgal growth and pollutant removal is known, but their impact on BPA-laden urine treatment is not well-studied.

Bisphenol A (BPA), a ubiquitous environmental endocrine disruptor, is suspected of disturbing brain development through largely unknown cellular and molecular mechanisms. In the central nervous system, oligodendrocytes are responsible for forming myelin sheaths, which enhance the propagation of action potentials along axons. Disruption of axon myelination can have lifelong consequences, making oligodendrocyte differentiation and myelination critical stages of brain development.

Preeclampsia (PE) is a pregnancy-related disease that poses a significant threat to the health of both the mother and the fetus. Previous studies have primarily focused on the role of the placenta in PE pathogenesis; however, normal decidualization is crucial for the subsequent development of the placenta and pregnancy. Bisphenol A (BPA) is an environmental endocrine disruptor commonly used in the synthesis of polycarbonate and epoxy resins.
