| 摘 要： | 对2006~2015年长沙市郊一蔬菜种植区进行定位监测,并测定灌溉水样、土壤和农区蔬菜品质各项指标。研究表明:2006~2015年,该监测点水质基本处于安全状态;土壤中Pb、As、Hg、Cr含量均处于安全范围,但Cd除2008年外均超过标准限量,说明该监测点土壤已经受到Cd污染;白菜样中的Pb、Cd、Hg含量有少数年份超标,2014~2015年白菜中4种重金属检测值均未超过标准限量。

| Abstract: | Long-term located monitoring was conducted at vegetable cultivation area in the suburb of Changsha City from 2006 to 2015, and some indicators of irrigation water, soil and cropland over vegetables quality were determined. The results showed that water quality was in the security state in the determining point from 2006 to 2015. In the meantime, the content of Pb, As, Hg, Cr in the soil were in a safe range, but the content of Cd was more than standard limits except 2008, which showed that the soil has been polluted by Cd. Meanwhile, the content of Pb, Cd and Hg in Chinese cabbage samples was more than standard limits alone or together in a few years, except 2014 and 2015. |
