我国菜田土壤重金属污染现状及检测技术分析

为解决我国菜田土壤污染问题,该文分析了园艺作物生产过程土壤重金属检测以及保障"菜篮子"产品可持续生产系统的重要意义。通过对我国东北、华北、南方、西部等地区的菜田重金属污染已有的调查研究工作进行综述,论述了我国菜田土壤重金属污染现状,并对污染总体情况、布局及趋势进行了分析;针对菜田土壤重金属含量的有效检测问题,介绍了现有重金属含量检测方法,并进行了现有常规及新型重金属检测手段的对比,提出了目前土壤重金属含量检测中面临的主要问题,为我国菜田园艺作物生产过程重金属污染检测和防治工作提供参考依据。

Current Status and Detection Technologies Analysis of Heavy Metals Pollution in Vegetable Fields

In order to solve the problem of soil pollution during vegetable production,the significance of detec- ting heavy metals pollution in soil during horticultural crops production was pointed out to ensure sustainable vegetable production. After reviewing the current research of heavy metals detection in vegetable fields at sev- eral regions in China such as the parts of northeast, north,south and west, the heavy metals pollution status in vegetable fields were expounded, the overview situation, layout and the trend of the soil pollutions in vegetable fields were analyzed. Aiming at the effective detecting problem of heavy metals content in vegetable fields, ex- isting detection methods of heavy metals were introduced, the common and new heavy metals detection methods were compared. Then the major problems of heavy metals detection were summarized,so as to provide a refer- ence for conducting detection and prevention of heavy metals pollution during process of horticultural crops production.
