文章尝试利用变量聚类分析方法对矿区附近农田土壤重金属污染的主要污染物进行辨识,并采用 综合主成分分析法对矿区附近农田土壤重金属污染情况进行评价和分级。分析结果表明:利用变量聚类分 析法可以有效地辨识矿区附近农田土壤重金属污染中的主要成分;运用综合主成分分析法,确定样本的综合 主成分,并对其排序和聚类,可以有效揭示矿区附近农田土壤重金属污染物的数据结构、相互关系和不同样 品点的污染程度。采用主成分分析方法对矿区附近农田土壤重金属污染情况的评价结果,反映了矿区主要 重金属污染物的影响,同时又定量化了土壤复合重金属污染研究。辨识和评价结果可为矿区附近农田土壤 重金属污染治理对策的提出和重点治理区域的确定提供参考和指导。

长江三角洲地区(简称长三角地区)是我国重要的工农业生产基地,关注该地区农用地土壤重金属污染状况对促进地区经济社会良性发展、保障生态环境安全具有重要意义。本文根据近 20 年发表的长三角地区农用地土壤重金属相关文献中的重金属含量数据,全面分析长三角不同区域农用地土壤典型重金属累积情况与污染状况,系统探究导致长三角地区农用地土壤重金属累积与污染的主要原因。分析发现,工业“三废”排放、交通运输、化肥、农药、农膜等的大量施用(使用),使得长三角地区农用地土壤中重金属 Cd 累积与污染情况最为严重,其次是 Cu、 Hg 和 Pb,而浙江台州和安徽铜陵分别存在Cd、 Hg 和 Cu, Cd、 Pb 和 Cu 多种重金属复合污染问题。针对长三角地区农用地土壤重金属污染防治的迫切需求和主要污染成因,在农用地土壤重金属污染源头控制、农用地土壤重金属快速动态监测、农用地土壤分级管理、重金属污染农用地土壤修复新技术研发、农用地土壤污染防治立法等方面提出了相关防治建议,以期为改善长三角地区农用地土壤生态环境、促进优质高效农业的可持续发展提供参考。

Ratio of turbidity and TSS (Tur/TSS) was used to characterize PSD of stormwater particles. Pb and Zn preferred to accumulate in finer RDS, while Cu, Cr and Ni in coarser RDS. HMs pollution in stormwater particles increased linearly with Tur/TSS. Dissolvability of HMs and PSD variations contribute to the differences between RDS and stormwater.

Soil contamination with heavy metal(loid)s threatens soil ecological functions, water quality and food safety; the latter is the focus of this review. Cadmium (Cd) and arsenic (As) are the toxic elements of most concern for food safety because they are relatively easily taken up by food crops. Rice is a major contributor of both Cd and As intakes to the Chinese population. Contamination and soil acidification are the main causes of high Cd levels in rice grains produced in some areas of southern China. The risk of Cd and As accumulation in food crops can be mitigated through agronomic practices and crop breeding. Liming is effective and economical at reducing Cd uptake by rice in acid soils. Paddy water management can produce opposite effects on Cd and As accumulation. Many genes controlling Cd and As uptake and translocation have been characterized, paving the way to breeding low accumulating crop cultivars through marker-assisted molecular breeding or genetic engineering. It is important to protect agricultural soils from future contamination. Long-term monitoring of anthropogenic additions and accumulation of heavy metal(loid)s in agricultural soils should be undertaken. Mass-balance models should be constructed to evaluate future trends of metal(loid)s in agricultural soils at a regional scale.
