Eight elements (Al, V, Fe, Ni, Zn, As, Sr, Cd) accumulated significantly in exposed oysters. Cd and Fe were partially eliminated during depuration. Cytotoxicity and genotoxicity increased markedly, correlating positively with internal Ni, Fe, and V levels. In contrast, LPO and ChE showed no significant changes. Despite significant bioaccumulation, all EDI and THQ values remained below USEPA safety thresholds, indicating no immediate risk to human consumers following a 30-day exposure. This is the first study to jointly evaluate ecotoxicological responses and human health risks in a native estuarine bivalve exposed to SePM, integrating environmental monitoring with food safety within a One Health perspective.

Additionally, observations at the boat pass highlighted the fish lock method as a significant factor affecting glass eel abundance, with efficiency depending on tidal range.

Focusing on China's coastal regions, the framework's adaptability and generalization capability were systematically validated. Seven key water quality indicators, namely COD<sub>Mn</sub>, WT, DO, TP, BOD<sub>5</sub>, NH<sub>3</sub>-N and pH, were determined by using random forest (RF) and extreme gradient boosting (XGBoost), and the accuracy rate was over 96 %. To evaluate model performance, seven machine learning (ML) algorithms, RF, XGBoost, extra tree (EXT), decision tree (DT), support vector machine (SVM), multiple linear regression (MLR), and k-nearest neighbor (KNN), were employed for WQI prediction; and six classifiers, RF, EXT, SVM, KNN, XGBoost, and naïve bayes (NB), were used for water quality grade classification. Among them, the EXT algorithm exhibited the best performance in WQI prediction, while XGBoost achieved the highest classification accuracy (98.32 %) with an AUC of 1.00 in all categories. In WQI model, weighted quadratic mean (WQM), unweighted root mean square (RMS), and arithmetic mean (AM) show strong generalization ability. Among them, the lowest fuzzy rate of the WQM model is 22.26 %, and that of the AM model is 22.45 %. Finally, XGBoost coupled with WQM and AM is selected for intelligent evaluation of coastal water quality in China. The results show that the overall water quality in China's coastal areas is good, with only two classes of “good” and “medium”, but no “marginal” or “poor” classes. Among them, the Yellow Sea has the best water quality, and the WQI score is generally higher than 80, all of which are “good” classes; The water quality in the South China Sea is relatively poor, and the WQI score is generally higher than 50, with the “medium” class as the main one.

Antibiotic resistance genes (ARGs) pose a significant threat to human health by promoting the spread of resistant pathogens, making infections harder to treat and increasing mortality risks.

In this study, we employed time-series metagenomics to investigate the responses of ARG profiles in free-living (FL) and particle-associated (PA) fraction to oxygen loss during a 22-day summer deoxygenation event in the East China Sea. In total, we identified 1,186 ARG subtypes and 2,279 mobile genetic element (MGE) subtypes. The most dominant resistance classes of antibiotics were multidrug (23.5%), followed by tetracycline (15%), macrolide-lincosamide-streptogramin (13.4%), peptide (10.3%), glycopeptide (8.7%), aminoglycoside (7.3%), and beta-lactam (4.9%). We found that ARG richness in FL fraction increased with declining oxygen levels, particularly for beta-lactam and multidrug class, while no significant relationship was observed in the PA fraction. Although the total relative abundance of ARGs in both fraction showed no significant oxygen dependence, beta-lactam and multidrug resistance genes in FL fraction significantly increased with oxygen loss. Co-occurrence network analysis revealed stronger positive associations between ARGs and MGEs in the FL fraction, suggesting enhanced gene transfer among environmental bacteria. Furthermore, neutral community model analysis indicated that stochastic processes also played an interactive role in shaping ARG composition dynamics in both bacterial fractions. Our findings provide evidence that coastal deoxygenation preferentially enriches high-risk ARGs (e.g., beta-lactamase genes) in FL bacteria through MGE-mediated transfer, highlighting escalating antibiotic resistance risks that threaten both ecosystem and human health under climate warming.
