Abstract: This article analyzes the method and control strategies of detecting soil cadmium content from the perspective of environmental sanitation monitoring. First, the materials and methods required for testing experiments are introduced, and the test results are explained. Subsequently, combined with the test results, the corresponding prevention and control measures are proposed, including taking precautions, building the relevant index system, and detailed discussing the applicable prevention and control strategies for water pollution and soil pollution.It is hoped that the relevant personnel can be inspired to provide theoretical reference for the orderly development of the future testing and prevention and control work.

随着工业排放物所含重金属的增加,土壤系统将难以维持原有的稳定性,研究表明,多数重金属均会给土壤功能造成危害,甚至对附近动植物的生长产生负面影响。作为导致土壤被污染的主要元素,镉给植物生长还有人体健康所带来影响有目共睹,要想使镉污染得到有效防治,关键是要对土壤中的镉含量加以明确,具体来说,就是基于环境卫生监测对镉进行检测,根据检测结果制定切实可行的防治方案,这也是本文所讨论的主要内容。
1土壤中镉含量检测实验
1.1实验材料
实验材料为水田土壤。检测土壤镉前需对监测点加以确定,保证所选择监测点兼具代表性以及完整性。以环境卫生监测所提出的要求为依据,选取某地区2个县进行土壤镉检测,通过随机抽取的方式,确定监测点,在各监测点对土壤样品进行采集,样品采集深度控制在10~15cm间,采样量以1kg为宜[1]。本次实验共采集水田土壤样品60份。……
