| 摘 要： | 对开封市郊区化肥河沿岸及全郊区土壤进行典型采样调查 ,研究了化肥厂含砷废水灌溉对土壤中砷含量的影响。结果表明 :(1 )不同灌溉方式下砷在土壤中的含量变化规律是重污灌区水浇地和菜地高于污灌混灌区耕地和菜地 ;(2 )土壤中砷含量沿化肥河以排污口为界向下游逐渐增加 ,垂直于河流流向因距河远近、不同土地利用方式也表现出明显的规律性变化特征。

| Abstract: | Impact of irrigat ion with arsenic-containing sewage from chemical fertilizer factory on soil arsenic content was evaluated based on sampling of representative soils along Huafei River and in the suburbs of Kaifeng city.The results showed that soil arsenic content varied among different irrigation patterns with higher soil arsenic content in high rate sewage irrigation area than in sewage irrigation and mixed irrigation areas.Soil arsenic content steadily increased along Huafei River from drainage out let downstream and showed a clear regularity as a function of the distance perpendicular to the direction of main stream and soil utilization patterns.The safe sewage irrigation duration obtained by correlation analysis was 30~35 years.Irrigation with clear water was an effective way to lower soil arsenic content. |
