Graphitic carbon nitride, an affordable and non-toxic compound featuring various C-N bonds, was utilized to grow highly branched polyamidoamine dendrimer on the zeolite/graphitic carbon nitride composite. Fourier transform infrared spectroscopy, X-ray diffraction analysis, field emission scanning electron microscopy, and energy-dispersive X-ray analysis were employed to confirm and characterize the material. The adsorption properties of the adsorbent for the removal of malachite green were examined using the batch method. Consequently, the key parameters affecting the adsorbent’s performance in removing malachite green (MG), such as pH, contact time, initial concentration, and adsorbent dosage, were investigated and optimized. The maximum adsorption capacity and removal efficiency of the adsorbent were found to be 1111 mg g<sup>−1</sup> and 99%, respectively, at a pH of 10, a low ZMPA/MG ratio of 6:10 mg mL<sup>−1</sup>, and a dye concentration of 200 mg L<sup>−1</sup> over a duration of 30 min. Various adsorption isotherms were analyzed, and the results were fitted to the Langmuir isotherm, which exhibited a high <i>R</i><sup>2</sup> value of 0.987. The adsorption capacity (385–1170 mg g<sup>−1</sup>) increased with rising dye concentrations from 200 to 1200 mg L<sup>−1</sup> under equilibrium conditions. These findings can be attributed to the strong electrostatic interactions and/or trapped dye molecules within the cavities between the adsorbent and the absorbed. The innovative zeolite composite may be considered a promising adsorbent for malachite green removal in diverse wastewater samples (from paint and textile industries) due to its high adsorption capacity and removal rate.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the varying numerical ranges and characteristics of different water quality parameters (WQPs), the selection of optimal retrieval algorithms is also different, which undoubtedly increases the complexity of different WQPs retrieval. To solve this problem, this study took the Hongjianao Lake in China as the research object, based on the measured data of chlorophyll-a (Chl-a), turbidity (TU), chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP), ammonia nitrogen (NH<sub>3</sub>-N), electrical conductivity (EC) and potential of hydrogen (pH) and Sentinel- 2 images, compared the ability of Boruta, recursive feature elimination (RFE) and shapley additive explanations (SHAP) methods to obtain the optimal feature subset. The random forest algorithm (RF), back propagation neural network algorithm (BP), and support vector machine algorithm (SVM) algorithms were used to retrieve lake water quality, and the coefficient of determination (R<sup>2</sup>), root mean square error (RMSE), mean absolute error (MAE), and the ratio of performance to deviation (RPD) were used to evaluate the prediction accuracy of multiple combined models from different aspects. The SHAP method was employed to quantify the contribution of input characteristics to WQPs. Subsequently, an integrated nutrient state index was established by utilizing the inversion results of Chl-a, COD, TN, TP, and NH<sub>3</sub>-N, along with the entropy weight method to assess the nutrient status level. The results showed that the optimal model, SHAP-RF, has better retrieval accuracy for WQPs (Chl-a, <i>R</i><sup>2</sup> = 0.66, RMSE = 0.28 µg/L; COD, <i>R</i><sup>2</sup> = 0.73, RMSE = 7.30 mg/L; EC, <i>R</i><sup>2</sup> = 0.69, RMSE = 160.58 us/cm; NH<sub>3</sub>-N, <i>R</i><sup>2</sup> = 0.59, RMSE = 0.11 mg/L; pH, <i>R</i><sup>2</sup> = 0.73, RMSE = 0.007; TN, <i>R</i><sup>2</sup> = 0.84, RMSE = 1.09 mg/L; TP, <i>R</i><sup>2</sup> = 0.65, RMSE = 0.015 mg/L; TU, <i>R</i><sup>2</sup> = 0.63 RMSE = 3.17 ntu).

The subtraction between the green and red bands was the first choice for EC inversion. The red-edge bands and their combination contribute significantly to TN inversion. TP was most sensitive to the red-edge bands and shortwave infrared bands. The red band exhibited the highest sensitivity to TU inversion.

We analyzed six reservoirs characterized by severe drought conditions in the Brazilian semiarid from 2014 to 2019. Exposed soil, open vegetation, and human occupation in the riparian zones of the reservoirs were the LULC classes with the most significant impact on total dissolved solids, dissolved inorganic nitrogen, salinity, and water volume. In contrast, an increase in forested areas was associated with a reduction in total phosphorus levels in the water. These human activities negatively affected taxonomic diversity while positively influencing secondary production by increasing the biomass of generalist and tolerant organisms. The negative relationship between forested areas and taxonomic diversity may be attributed to the extreme reduction in water volume caused by drought and the combined effects of multiple land uses surrounding the reservoirs. This exacerbated environmental stress and diminished the potential benefits of riparian vegetation on biodiversity. These findings highlight the importance of considering multiple factors related to land use, human activities, and climate to effectively conserve water quality and biodiversity in the reservoirs.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, soil samples were carried out following standard protocol. The concentration of nutrients after treatment revealed increase in nutrients level in 28 days of treatment as the weight of sludge dosage rises from 0 to 30%. However, as the remediation period progresses from 28 to 56 days, nutrients level of effluent and soil begins to drop, though nutrients level after the treatment period falls within the permissible range of habitat and agricultural soil after remediation period. The level of cyanide after treatment revealed a drop in concentration of effluent/soil as the dosage of sludge rises. In the same vein, concentration of effluent/soil cyanide also drop as the period of incubation increases from 28 to 56 days. The decrease in the level of cyanide is more pronounced in the 42nd and 56th days of treatment.
