Summary: Conventional water treatment methods are ineffective in removing endocrine disrupting compounds (EDCs) from wastewater. Electrochemical Advanced Oxidation Processes (eAOPs) show promise in oxidizing EDCs but produce unknown transformation products (TPs). A comprehensive evaluation of these technologies is necessary for safe real-life application. This study demonstrated the electrochemical degradation of 17α-ethinylestradiol (EE2) using a boron doped diamond anode with different supporting electrolytes, quantified EE2 and identified TPs using liquid chromatography and mass spectrometry, and evaluated estrogenic activity using transgenic medaka fish. The results showed high removal efficiency of EE2 but also the generation of potentially toxic TPs, highlighting the need for caution in the use of eAOPs.

Summary: This study investigated the genetic toxicity of chlorinated sediment hydrophobic organic compounds (HPOCs) from reservoirs along the Dongjiang River. The results showed that the hydrophilic organic compounds (Cl-HICs) were the major contributors to oxidative damage and dioxin-like toxicity compared to the hydrophobic organic compounds (Cl-HOCs). Antioxidants were found to significantly reduce the reactive oxygen species (ROS) induced by Cl-HOCs and Cl-HICs, but had little effect on DNA oxidative damage.

Summary: An increasing level of pesticide exposure is observed due to the consumption of fruits, vegetables, and grain products in a vegetarian diet. Certain fungicides commonly used in Poland were found to potentially exhibit endocrine-disrupting properties, leading to adverse effects on cell viability, proliferation, and antioxidant capacity. It is important to avoid exposure to these fungicides.

Summary: Spinal cord injury (SCI) refers to the damage of the spinal cord caused by either trauma or disease. SCI is characterized by various injury phases that affect the transmission of sensory and motor signals, resulting in temporary or long-term functional deficits. Estrogens and estrogenic compounds have been shown to effectively alleviate the effects of SCI, making them potential treatment options.

Summary: Life-history traits of the popular piscivore species Lateolabrax latus were investigated along the western Pacific coast, revealing a main spawning period from January to March, a maximum age of 11 years, and larger body size in females. Understanding these basic life-history traits is crucial for better ecological understanding and management of this important predatory fish species.

Summary: The study reveals that anthropogenic pollution has a negative impact on the ecological state of the Nidda River, leading to liver lesions and abnormal function of the CYP1A1 system in fish. There is minimal variation between seasons and sampling sites, but it was observed that liver condition is poorest during the spawning season and downstream of industrial dischargers, tissue integrity and EROD activity are most affected. Different fish species show varying sensitivity to pollution, with brown trout being the most impacted and European chub being less affected.

Summary: This study examined the biomonitoring and ranking effects of polycyclic aromatic hydrocarbons (PAHs) pollution on rockfish in the Maowei Sea, China. The results showed moderate concentrations of PAHs in the surface seawater, indicating industrialization and urbanization as possible sources. Significant differences in enzyme activities and metabolites were observed between different areas. The fish expert system (FES) demonstrated higher biological effect levels in certain sampling sites.

Summary: This review summarizes the pretreatment and determination methods for estrogenic disruptors in dairy products. Solid-phase extraction (SPE), liquid phase microextraction (LPME), gas chromatography-mass spectrometry (GC-MS), liquid chromatography-mass spectrometry (LC-MS), Raman spectroscopy, and biosensors are discussed as potential techniques for analyzing e-EDCs. The findings provide a reliable theoretical basis and operational method for future e-EDC analysis.

Summary: This study investigates the estrogenic activity of bisphenol A (BPA) and its analogues using zebrafish-based assays. The results suggest that these compounds have hormone-like effects on the heart and liver of zebrafish, and their activation of estrogen receptors varies. The study also identifies a gene that can serve as a biomarker for estrogenicity in larval fish.

Summary: An estimated 1.5-2.7 billion wild fish are caught by UK commercial sea fishing fleets annually, most of which are subjected to severe stressors during capture. While fish are recognized as sentient beings in UK law, commercially caught wild fish are excluded from welfare protections, leading to major welfare issues in wild capture sea fisheries with great potential for reforms.

Summary: This study examines the impact of maternal foraging strategies during pregnancy on neonatal health and survival in South American fur seals. The results show that mothers who shift towards a benthic-nearshore foraging strategy during late pregnancy give birth to pups with greater body mass, higher glucose levels, and lower blood urea nitrogen levels. These pups are more likely to survive compared to those born to mothers using a pelagic-offshore foraging strategy. The findings suggest that maternal foraging strategies during late pregnancy can influence neonatal survival through the transfer of glucose to the fetus.

Summary: This study evaluated the short- and long-term cellular tolerance responses in two brown macroalgae species of Dictyota genus under controlled laboratory conditions. The results showed that high salinity values induced changes in photosynthetic parameters and oxidative stress measurements, but did not cause significant damage to the photosynthetic apparatus. These findings contribute to the understanding of cellular tolerance strategies in Dictyota spp. and their potential use in biomonitoring desalination impacts in the field.

Summary: Human pressure from industrial and agricultural development has led to a biodiversity crisis, with environmental pollution being one of the main drivers. Studies in South America have focused on the concentrations of endocrine disruptor chemicals in animals, but there is limited understanding of their effects on reproductive and thyroid levels. Future research should prioritize emergent contaminants and evaluate their impact on native species using available methods.

Summary: Anthropogenic activities have led to an increase in trace elements in the environment, which can have harmful effects on biota. Seabirds, especially gulls, are used as bioindicators of environmental pollution and have been found to accumulate high levels of trace elements. However, the research on lesser-known trace elements in gulls is limited, and future studies should focus on these elements.

Summary: This study examined the ecology of brown trout and native fish species in two adjacent rivers in Chilean Patagonia. The results showed that brown trout dominated the fish community in terms of biomass and showed distinct diets in the two rivers. The study highlights the importance of understanding interactions between native and introduced species at local spatial scales.
