“…As a result, cadmium poisoning often leads to diseases and organ dysfunction, such as renal insufficiency, lesions, hypertension and even cancer [6]. These toxic metal pollutants are continuously being discharged into the environment, exacerbating the pollution of the environment [7,8]. Even without direct exposure to these metal contaminants, they can eventually endanger human health through bioconcentration.…”

Carbon dots and metal-organic frameworks (MOFs) have been widely used in a variety of applications such as sensing, energy storage, and catalysis, with fewer applications in electrochemical sensing. In this study, C-Dots/UiO-66-NH2 was prepared as a modified material for glassy carbon electrodes for the detection of cadmium and lead ions in water by electrochemical methods (DPV) by selecting m-phenylenediamine as a source of carbon dots and amino-functionalized zirconium-based metal-organic frameworks, which are the combination of these two popular materials. Due to the complexation of amino groups with metal ions, a sufficient amount of amino groups provided a good interface for the adsorption of metal ions. Under the optimal deposition conditions, C-Dots/UiO-66-NH2 exhibited good linearity and excellent detection limits for metal ions (Cd2+, Pb2+) in the concentration range of 30 to 180 µg/L. The results showed that C-Dots/UiO-66-NH2 was suitable for the determination of Cd2+ and Pb2+ in water. In addition, the C-Dots/UiO-66-NH2/GCE sensor has good immunity to interference and detection stability.

Landfill leachate has great pollution risk to groundwater, which is of practical significance to study the characteristics of leachate leakage and surrounding groundwater pollution and its harm to human health. Taking a typical valley-type landfill in South China as the research object, this paper ascertained the leakage area based on geophysical methods and groundwater sampling. A total of 21 parameters such as pH, total hardness (TH), total mineralization (TM), permanganate index (CODMn), ammonium (NH3-N), nitrites (NO3-N), nitrates (NO2-N), sulphates (SO4−), chloride (Cl−), fluorides (F−), volatile phenols, cyanide, and heavy metals (HMs) in groundwater and some indicators in leachate were tested, and the water quality and health risks were evaluated by using the Nemerow pollution index (NPI) method and BCRA (Rish-based Corrective Action) model. The results indicate that the leakage areas are existing in the middle of the landfill site, the middle and the south of the anti-seepage dam with a depth about 15-22m and main pollutants of CODMn and NH3-N. The main pollutants of pH, NH3-N, Fe and Mn were ranged from 5.80 to 6.70, 0.06 to 0.74 mg/L, 0.002–2.763 mg/L, and 0.003–1.181 mg/L, their rates exceed the class Ⅲ standard at 28.57%, 28.57%, 4.29% and 14.29%, respectively. The Nemerow pollution index showed that the groundwaters at ZK01 and ZK04 were seriously polluted. Groundwater quality was affected by leachate and natural geological background. The total non-carcinogenic risk of groundwater was ranked as LS102 < LS101 < ZK02 < ZK01 < ZK03 < ZK05 < ZK04, with Cl− and Mn as the main non-carcinogenic pollutants in the landfill. This rank reveals the rule that the closer to the waste body, the higher the risk.
