BackgroundFish contains high-quality omega-3 fatty acids, protein, vitamins, and minerals due to this it is termed as an essential component of a balanced diet. But there have been concerns raised about the risks consuming fish that contaminated with toxins such methylmercury, polychlorinated biphenyls (PCBs), dioxins, pesticides, plastic waste. Consumption containing these pollutants raising global mortality morbidity rates.Scope approachesThe review examines current research outputs on health benefits potential consumption. The also discusses various approaches mitigating problems caused by consumption, highlights roles balancing when fish.Key findings conclusionDifferent indicated contaminants cause cancer, kidney failure, adverse neurological effect, cardiovascular diseases, so vulnerable groups pregnant, child breast-feeding children. In conclusion, need get more tangible evidence advantages disadvantages consumption safeguard wellbeing society.

Flame retardants (FRs) are chemical substances used to inhibit the spread of fire in numerous industrial applications, and their abundance modern manufactured products indoor outdoor environment leads extensive direct food chain exposure humans. Although once considered relatively non-toxic, FRs demonstrated by recent literature have disruptive effects on many biological processes, including signaling pathways, genome stability, reproduction, immune system function. This review provides a summary research investigating impact major groups FRs, halogenated organophosphorus animals humans vitro and/or vivo. We put focus those studies that explained or referenced modes FR action at level cells, tissues organs. Since highly hydrophobic chemicals, biophysical biochemical usually involve lipophilic interactions, e.g. with membranes elements pathways. present selected toxicological information about these molecular actions show how they can lead damaging membrane integrity, DNA compromising its repair, changing gene expression, cell cycle as well accelerating death. Moreover, we indicate this translates deleterious bioactivity physiological level, disruption hormonal action, dysregulation metabolism, adverse male female reproduction alteration normal pattern immunity. Concentrating subjects, make clear both advances knowledge years remaining gaps our understanding, especially mechanistic level.

In this study, 245 representative samples of aquatic products were selected from local markets in Shenzhen by stochastic sampling. The comprised eight species and fell into three product categories: fish, crustaceans, bivalves. A total BPs determined liquid chromatography coupled with mass spectrometry, namely, bisphenol (BPA), AF (BPAF), AP (BPAP), B (BPB), S (BPS), P (BPP), Z (BPZ), F (BPF). All detected products, except for BPAF, indicating pervasive contamination products. BPS demonstrated the highest detection rate both before after enzymatic hydrolysis, whereas BPAP exhibited lowest hydrolysis BPB displayed hydrolysis. concentration difference proved to be statistically significant. Moreover, 49–96% found combined state, underscoring essentiality conducting detections on following While health risks associated ingesting residues through consumption minimal residents at risk exposure, results suggest necessity more stringent regulations governing

Evaluating the health of river surface water is essential, as rivers support significant biological resources and serve vital drinking sources. While Water Quality Index (WQI) commonly employed to evaluate quality, it fails consider biodiversity does not fully capture ecological rivers. Here we show a comprehensive assessment in lower Yangtze River (LYR), integrating chemical metrics. According traditional WQI metrics, LYR's generally meets China's Class II standards. However, also contains 43 high-risk emerging contaminants; nitrobenzenes are found at highest concentrations, representing 25-90% total detections, while polycyclic aromatic hydrocarbons present most substantial environmental risks, accounting for 81-93% risk quotient. Notably, plankton-based index integrity (P-IBI) rates majority LYR samples (59.7%) 'fair', with significantly better observed autumn compared other seasons (

Abstract Dirty dozen chemicals (DDCs) are a group of 12 extremely toxic that were recognized at the Stockholm convention in 2001 for their severe impact on ecosystem and human health. Despite embargo restraint placed DDCs usage, these continue to find way into because they still secretly or openly applied by many nations, especially African regions. Moreover, can be perceived where have been employed previously before treaty due persistent profile. This study aimed critically review original works directed toward removal various dirty using covalent metal–organic frameworks (COFs MOFs). Specifically, this study, COFs/MOFs composites with remarkably tailored adsorptive profiles evaluated adsorption efficiency different DDCs. In addition, effect operating parameters importance environmentalists stakeholders optimization purposes was empirically discussed. also fills knowledge vacuums about COF/MOF‐DDCs process, offers insights reusability potential, fundamental mechanism, isotherm, kinetic modeling, framework future studies. Findings from revealed COF MOF high DDC capacity potential attributed admirable porosity existence plethora oxygen‐rich functional groups allow better interactions through chelation, halogen bonding, H‐bonding, π‐π stacking. points upscaling remediation technique. Future researchers need direct more efforts use density theory mechanism interpretation, exploration hybrid technology, cost analysis, scalability, thermodynamics, adsorption, desorption modeling.
