Abstract Per- and polyfluoroalkyl substances (PFASs), which have their origins in both industrial processes consumer products, can be detected at all treatment stages wastewater plants (WWTPs). Quantifying the emissions of PFAS from WWTPs into marine environment is crucial because potential impacts on receiving aquatic ecosystems. In this study, levels five were measured influent effluent sewage water samples obtained a municipal WWTP, discharges flow False Bay, Indian Ocean coast Cape Town, South Africa. Additionally, seawater, sediment, biota eight sites along Bay also analysed. Results showed high prevalence different environmental matrices. Perfluorononanoic acid was most dominant these matrices with maximum concentration wastewater, 10.50 ng/L; 18.76 239.65 ng/g dry weight (dw); invertebrates, 0.72–2.45 µg/g dw; seaweed, 0.36–2.01 dw. The study used chemical fingerprint PFASs WWTP effluents to track dispersion across large, previously pristine examined how each accumulated organisms. demonstrates that primary secondary cannot fully remove such compounds. There thus need improve quality before its release promote continuous monitoring focusing sources PFAS, including transformation fate ecological risks, particularly areas WWTP.

Reproductive system diseases pose prominent threats to human physical and mental well-being. Besides being influenced by genetic material regulation changes in lifestyle, the occurrence of these is closely connected exposure harmful substances environment. Endocrine disrupting chemicals (EDCs), characterized hormone-like effects, have a wide range influences on reproductive system. EDCs are ubiquitous natural environment present industrial everyday products. Currently, thousands been reported exhibit endocrine this number likely increase as testing for potential has not consistently required, obtaining data limited, partly due long latency many diseases. The ability avoid EDCs, especially those artificially synthesized origin, increasingly challenging. While can be divided into persistent non-persistent depending their degree degradation, recent uptick research studies area, we chosen focus pertaining detrimental effects health several that widely encountered daily life over past six years, specifically bisphenol A (BPA), phthalates (PAEs), polychlorinated biphenyls (PCBs), parabens, pesticides, heavy metals, so on. By focusing impact hypothalamic-pituitary-gonadal (HPG) axis, which leads development diseases, review aims provide new insights molecular mechanisms EDCs’ damage encourage further in-depth clarify potentially EDC through various other mechanisms. Ultimately, it offers scientific basis enhance risk management, an endeavor significant societal importance safeguarding health.

The number of pollutants and chemicals with the potential to reach environment is still largely unknown, which poses great challenges for researchers in various fields science, environmental scientists, analytical chemists. Chromatographic techniques, both gas chromatography (GC) liquid (LC) coupled different types detection, are now invaluable tools identification a wide range chemical compounds contaminants water. This review devoted chromatographic techniques GC-MS, GC-Orbitrap-MS, GC-MS/MS, GC-HRMS, GC × GC-TOFMS, GC-ECD, LC-MS/MS, HPLC-UV, HPLC-PDA, UPLC-QTOFMS, used determinate emerging organic aquatic media, mainly urban water, published scientific literature over past several years. article also focuses on sample preparation methods analysis aqueous samples. Most research minimizing steps, reducing amount solvents used, speed analysis, ability apply it analytes sample. extremely important application sensitive selective monitor status water quality assess its impact human health.

The presence of contaminants emerging concern (CECs) in agricultural and fisheries water has raised significant environmental health concerns. Vacuum membrane distillation (VMD) shown promise as an effective method for removing non-volatile contaminants, such CECs, from water. This study presents a novel application bench-scale VMD unit to treat Lagoa da Conceição, Florianópolis, Brazil, using microporous membranes (0.22 µm) under the following optimized conditions: 75 °C, flow rate 24 L·h-1, vacuum pressure -640 mmHg. system demonstrated remarkable performance several key antimicrobials, including sulfamethoxazole, ciprofloxacin, azithromycin, clindamycin (500 μg·L-1), with rejection rates 99.1%, 98%, 99.9%, 99%, respectively, average flux 7.08 L·m-2·h-1. Additionally, achieved substantial 99.98% salt rejection. Ecotoxicity tests revealed low toxicity azithromycin but high clindamycin, while human risk assessment indicated moderate-to-high risks ciprofloxacin clindamycin. findings highlight potential sustainable technology removal CECs biocompounds, enhancing safety reducing hazards. offers promising solution addressing contamination on broader scale.

Abstract Contaminants of emerging concern (CECs) pose a significant threat to human and ecosystem health due their persistence, bioaccumulation in higher trophic levels, potential toxicity. While vivo models are commonly used for toxicity screening, developing alternative vitro techniques rapid environmental risk assessment is essential. Spermatozoa, with compartmentalized structure, measurable characteristics sensitivity changes, offer as an model screening. We evaluated the impact selected CECs, including pharmaceuticals pesticides, on sperm function highly motile subpopulations from donor semen. Standardised protocols were applied assess various functional parameters after 1–4 h exposure either individual or mixture chemicals. Our findings revealed that total motility insufficient detect subtle toxic effect. More responsive measures, such kinematics, induced hyperactivation, viability, mitochondrial membrane (MMP) presence reactive oxygen species (ROS) should be assessed elucidate effect environment function. Most chemicals exerted dose–response parameters, concentrations resulting most negative effects. The inherent spermatozoa oxidative stress, damage energy metabolism, makes them robust assessing These features highlight utility cellular evaluating CECs advancing methodologies.

Water quality is continuously deteriorating due to various drivers of change, including rapid urbanization, industrial development, inadequate sanitation facilities, and climate change. Furthermore, the detection newly monitored emerging contaminants, which are not always fully regulated, has turned water pollution into a "time bomb" on verge exploding. While laboratory-based methodologies offer significant advantages, such as high sensitivity, accuracy, selectivity, steady growth sensors soft for on-line on-site monitoring purposes cannot be overlooked. This review focuses sensor innovations over past five years, providing an in-depth comparison between classical methods novel advanced technologies. It also explores current strategies controlling potential regulation limits, solutions overcome transboundary challenges management. Special attention given class perfluoroalkyl compounds (PFAS), ubiquitously found in matrices. For them, traditional technologies presented evaluate their reliability future off-lab applications.
