“…In addition, AGNPS pollution presents characteristics such as complexity, hysteresis, multiple sources of pollution, wide distribution, difficulty in control, etc. [11,12]. Many studies have reported that chemical fertilizers, soil particles, microplastic particles, livestock manure and pesticides can enter soil surface runoff and underground runoff under rainfall conditions.…”

With the expansion of the scope and diversity of agricultural non-point source (AGNPS) pollution, environmental pollution in water bodies and soils has intensified, seriously affecting the quality of life of urban and rural residents. This paper presents a comprehensive analysis of the current status of AGNPS pollution from five aspects: fertilizers, pesticides, agricultural films, livestock and crop residues. The study also includes a comprehensive risk assessment of the nitrogen and phosphorus pollution, microplastic pollution, and heavy metal contamination attributed to the current AGNPS pollution in China. The findings reveal widespread nitrogen and phosphorus pollution across provinces in China, a low risk of microplastic pollution, and acute contamination with heavy metals such as As, Cd and Hg, notably in Hubei, Gansu, Liaoning, Guizhou, and Hunan. Additionally, the study reveals that in Chinese provinces currently facing severe heavy metal pollution, heavy metal contamination constitutes a significant carcinogenic risk to adult health and a serious non-carcinogenic risk to child health. Consequently, guided by the ‘3R theory’ principles of source reduction, interception, and remediation, this paper suggests an array of expanded strategies for AGNPS pollution management. These strategies are proposed to aid in the sustainable advancement of AGNPS pollution control.

The present study investigates the electrocatalytic nitrate reduction reaction (NRR) on a Cu/Au electrode surface in a neutral pH potassium chloride (KCl) environment saturated with nitrogen, oxygen, and carbon dioxide, three of the most abundant atmospheric gases. The electrode was characterized using OCP, EIS, SEM, EDX, XPS, and XRD to assess its electrochemical properties, catalytic feasibility, and surface morphology. Results indicated that nitrate ions undergo a consecutive reduction process ( → → ) on the Cu/Au electrode. O2 saturated environment impeded the NRR process through O2 adsorption on the electrode surface prior to the → conversion. In contrast, CO2 saturated condition enhanced the reaction by neutralizing the NRR byproduct ions, thus accelerating the overall NRR kinetics. Under CO2 environment the NRR process was found more facile compared to that of other two gases. NRR took place at a peak potential of −0.71 V and −1.06 V for the first and second reduction wave, respectively. Kinetic analysis showed that the reduction reactions in presence of CO2 followed first‐order, diffusion‐limited kinetics. The Cu/Au electrode exhibited high sensitivity (3.49×10−1 μA μM−1) with an LOD of 0.46 μM for nitrate detection, and finally demonstrated excellent performance in real sample analysis.
