Rapid global climate change causes seawater intrusion (SWI) and soil salinization, significantly altering the environmental behavior of heavy metals. However, the toxicity and related mechanisms of heavy metals under such conditions remain unclear. Herein, the effects of salinity and independent salt ions on the toxicity of hexavalent chromium (Cr(VI)) to barley root elongation were systematically investigated and an optimized biotic ligand model (BLM) was developed for Cr(VI) phytotoxicity prediction. The results reveal a nonlinear salinity-dependent Cr(VI) phytotoxicity. Specifically, toxicity decreases by 30% as the salinity increases from 0.05‰ to 1‰, and reaches a minimum at 1‰, but increases up to 3-fold at high salinity (8‰). This transition is attributed to the opposite effects of sulfate (SO42-) and chloride (Cl-) ions, as univariate experiments demonstrate that SO42- substantially inhibits Cr(VI) phytotoxicity, while Cl- exhibits a synergistic effect. Thus, the optimized Cr(VI)-BLM (R2 = 0.95, RMSE = 7.71%) was developed by incorporating the effects of salt ions (SO42- and Cl-) and main toxic Cr(VI) species (chromate (CrO42-) and sodium chromate (NaCrO4-)), achieving substantially improved prediction accuracy compared with the traditional free ion activity model (FIAM) (R2 = 0.87, RMSE = 12.53%). Furthermore, the optimized Cr(VI)-BLM was applied to quantify the toxic potency of different Cr(VI) species (CrO42-, hydrogen chromate (HCrO4-), and NaCrO4-) and confirm main toxic Cr(VI) species shifts from CrO42- to NaCrO4- with increasing salinity. These findings provide a critical theoretical foundation for ecological risk assessment of Cr(VI) in coastal areas under climate-induced SWI and soil salinization.

Technetium-99 (99Tc) contamination in marine environment is garnering increasing global concern, primarily due to its increasing releases from nuclear-contaminated water and spent fuel reprocessing activities. 99Tc with long half-life predominantly exists as TcO₄⁻ in marine environment, having high solubility and strong mobility in seawater, posing a serious risk to marine ecosystems. Although pollution status and accumulation behaviors of 99Tc in marine organisms have been reported, they have great limitations regarding the specific accumulation and transfer mechanisms within marine food chain. Herein, we critically synthesized the sources, geochemical distribution, transport behaviors, and biological transfer of 99Tc in marine environments, with emphasis on the microbially mediated redox processes that regulate the fate and bioavailability of 99Tc. We showed that the Irish Sea was among the ocean regions most impacted by 99Tc contamination and its concentration was up to 550 mBq L⁻¹. Additionally, we had reviewed the research achievements of 99Tc distribution in marine ecosystems, focusing on its bioaccumulation mechanisms in marine organisms like brown algae, holding the highest distribution concentration of 99Tc (19,700 Bq kg⁻¹). Notably, trophic transfer efficiency (TTE) and food chain transfer factor (FCTF) values were defined to evaluate the food-web transfer behaviors of 99Tc among different marine species. The highest TTE value (31.65%) was observed in the transfer from crustaceans to mollusks, while the highest FCTF value (49.86%) was found in the transfer from brown algae to crustacean. Future perspectives were also proposed for advancing the deep understanding of 99Tc contamination in marine ecosystems.

Elucidating the formation mechanism of geogenic contaminated groundwater (GCG), mainly polluted by arsenic (As), fluorine (F) and iodine (I), is crucial for elucidating relevant processes and improving water quality. The study focused on the Huang-Huai-Hai Plain in Henan Province, China, using 484 groundwater samples collected repeatedly from 2020 to 2022 combined with hydrogeochemical analysis and Positive Matrix Factorization (PMF) to identify GCG characteristics, controlling mechanisms, and health risks. Results indicated that the groundwater ranged from weakly acidic to alkaline, with confined water being predominantly weakly alkaline to alkaline, and exhibited high salinity. Groundwater with high concentrations of As, F, and I was predominantly found in alluvial and fluvial zones. Groundwater chemical composition is affected by evaporation and water-rock interaction, and the primary types of low-quality groundwater are mainly the evaporation-concentration and burial-dissolution types. Spatial analysis indicates the distribution of As, F, and I poisoning villages corresponds with areas of high-As, high-F, and high-I groundwater. Groundwater pollution poses the highest non-carcinogenic risk for children, and high-As groundwater poses the highest carcinogenic risk to this group. Additionally, potential endemic goiter areas are mainly in the flood plain. These findings indicate that groundwater safety is intrinsically linked to endemic diseases. Mitigating health risks necessitates targeted groundwater treatment, prioritized monitoring of high-risk zones, and integrated management of GCG influences to ensure safe water access for vulnerable communities.
