摘要: 对武汉市东湖主湖区的郭郑湖和塘林湖114个沉积物样品的磁化率与代表性样品的频率磁化率系数、磁滞回线参量和重金属元素进行系统分析, 综合区域环境背景, 探讨应用岩石磁性方法技术评价大型城市内陆湖泊沉积物污染程度的可行性及其效果.结果表明, 在主成分中, 郭郑湖沉积物没有一个主成分占绝对优势, 仅有少数重金属元素含量与磁化率相关, 磁化率χ与重金属富集强度的相关性较差; 而塘林湖沉积物有一个“工业源”的主成份占绝对优势, Fe (全铁)、Co、V、Mn、Ti、Ba、Cr、Ni、Cu等元素与饱和等温剩磁SIRM、χ关系密切(相关系数大于0.87).郭郑湖与塘林湖的沉积物的饱和等温剩磁与重金属富集强度的相关程度高于磁化率, 因此, 可以用其(SIRM) 作为环境污染程度的指示参量.Abstract: In order to probe the relationship between urbanization processes and the extent of water contamination, measurements were taken the magnetic susceptibility (χ) of 114 samples, and of the frequency-dependent susceptibility and magnetic hysteresis parameters and heavy metal of representative samples from sediments of Guozheng Lake and Tanglin Lake, Wuhan, Hubei Province.Resultsshow that in Guozheng Lake no principal component predominates and the correlation between susceptibility and heavy metal content is low. However, in Tanglin Lake, a principal component originating from industry predominates. Fe (total iron), Co, V, Mn, Ti, Ba, Cr, Ni and Cu are highly correlated with saturation (Ms), isothermal remanent magnetization (SIRM) and χ and the correlation coefficients are generally higher than 0.87. For sediments of both lakes, the correlation of SIRM with contents of heavy metals is higher than that of χ. So, saturation isothermal remanent magnetization (SIRM) can be considered as a proxy of the extent of heavy metal pollution.
