              土壤渗流是农田土壤重金属输出的重要途径，过度耕种会加剧土壤水分和营养的流失，而降水会对这一过程产生影响。通常，土壤重金属渗流通量通过质量平衡模型间接计算，该模型假设土壤中未渗流的重金属通过径流途径输出。
            </p>
             <p>
              图详细展示了土壤渗流作为重金属纵向迁移重要途径的过程。如图所示，土壤中的重金属在降水和重力作用下，通过土壤孔隙向下渗透，最终进入地下水系统。图中左侧部分清晰地描绘了农田土壤剖面，包括表层土壤、根系分布区以及下方的地下水层。土壤中的水分和溶解态重金属随着水流向下移动，形成明显的渗流路径。
