In order to find out completely the soil-wheat contaiminated by heavy metals in Tianjin sewage farm, we collect samples on the dry land and examinate contents of heavy metals in soil-wheat system. Firstly, the anthor evaluates that soil irrigated by sewage that has been contaminated slightly, the main polluting factors are Cd and Zn, and then the anthor evaluates soil according to different regions, soil types and irrigating water. Secondly, the anthor analyzes content and enrichment ability of heavy metals in different part of wheat, evaluates wheat is contaiminated by Cd widespreadly, only few samples polluted by Zn.Finally the anthor put up correlative analysis about heavy metal contents in the soil-wheat system, as well as plant enrichment coefficient and some physico-chemical properties of soil, and establishes a prognostic model about heavy metal content among wheat spike, soil, soil types, PH, organic matter and salinity with the quantifying theory.The prognostic accuracy of primarily contaminative factors is the best with compound correlative coefficient examining, the model can be founded.With improvement of living level, people need cleaner food.
为全面了解天津市污灌区农产品生产地土壤和旱地作物小麦的重金属污染状况,我们于2004~2005年对全市污灌区的土壤和小麦进行了采样,在对该区土壤—小麦系统中六种重金属元素(Cd、Cu、Pb、Zn、Cr和Ni)的含量进行检测的基础上,本文首先分析评价了污灌区农田土壤的环境质量总体已达到了轻度污染水平,主要的污染因子是Cd和Zn,同时对污灌区农田土壤分区县、土壤类型和不同灌水类型进行了评价;然后分析了重金属在小麦不同部位的含量与富集能力,评价了污灌区旱地作物小麦普遍遭受了Cd的污染,只有个别样点遭受了Zn的污染;最后对土壤—小麦系统重金属含量间以及植物富集系数与土壤部分理化性质间进行了相关分析,由于土壤类型是定性变量,本论文以数量化理论建立了小麦穗实中重金属含量与土壤中重金属全量、土壤类型、PH值、有机质和全盐量间的预测模型,经复相关系数检验,污灌区主要的污染因子Cd和Zn的预测精度最高,模型可以成立。

Cyanide in water, in tissues of aerial part of plants and in air was analyzed spectrophotometrically. Results from this study indicated less than 10.85% reduction of the applied iron cyanide complex was detected in hydroponic solution in the presence of plants. Little amounts of cyanide were found in all parts of plant tissues, indicating the passage of ferrocyanide through the plants.
结果表明:(1)低浓度实验组52.99mg CN L^(-1水溶液中10.85%的亚铁氰化物被植物吸收,随着浓度的升高吸收到植物体内的亚铁氰化物的比例依次递减,但是统训学分析显示各实验组单位体重的植物吸收亚铁氰化物的量无显著性差异;(2)在植物的各个部位都能检测到微量的亚铁氰化物,表明亚铁氰化物通过植物的蒸腾作用在植物体内的迁移。
