摘　　要：时隔40年,我国终于在2022年迎来了全国第三次土壤普查,这40年来,我国经历了快越式发展,城乡加速融合,但是由于这40年来的不合理开发,环境也受到了巨大的影响,为全面掌握土壤资源状况,国家将全面展开第三次土壤普查。本次将根据土壤三普测定砷和汞指定用国家标准《土壤质量总汞、总砷、总铅的测定原子荧光法》(GB/T 22105-2008)和行业标准《土壤和沉积物砷、汞、硒、锑、铋的测定微波消解/原子荧光法》(HJ 680-2013)进行一次方法比较,寻求效益更好的科学技术,以便于之后使用。After 40 years,China finally ushered in the third national soil survey in 2022.Over the past 40 years,China has experienced rapid development and accelerated urban-rural integration.However,due to the unreasonable development in the past 40 years,the environment has also been greatly affected.In order to fully grasp the status of soil resources,the state will carry out the third soil survey in an all-round way.This time,a method comparison will be made according to the national standard for the determination of total mercury,total arsenic and total lead in soil quality atomic fluorescence method(GB/T 22105-2008)and the industrial standard microwave digestion/atomic fluorescence method for the determination of arsenic,mercury,selenium,antimony and bismuth in soil and sediments(HJ 680-2013),so as to seek more effective science and technology for later use.
