摘要
根据土壤类型、土地利用现状,较系统地研究了四川省攀枝花市芒果基地土壤和芒果镍污染含量。结果表明,西区、盐边、仁和区芒果基地土壤镍平均值分别为47.9、39.2和21.7 mg/kg,超过国家Ⅱ级环境标准值的达分别达30%、41%和5%。除仁和基地外,其它二基地土壤明显高出我国其它地区镍普遍含量(20.7~31.1 mg/kg)。母质是影响土壤镍变异的主要因素。西区、盐边、仁和基地芒果镍平均值分别为0.80,0.66,0.60 mg/kg(干样计),芒果中平均镍含量与各基地土壤镍平均含量之间呈现出正相关趋势。
The Ni pullutions both in soil and mango in mango base in Panzhihua city of Sichuan province were studied.The sample were collected according to the soil type,the using purpose of land.The results showed that the Ni average contents were 47.9,39.2 and 21.7 mg/kg respectively in West district,Yanbian and Renhe mango base and there were 30 %,41 % and 5 % of Ni contents in soil surpass the Ⅱgrade environment standard in West district,Yanbian county and Renhe district respectively.The average Ni values in soil were higher than those of common Ni contents in other districts of China(20.7-31.1 mg/kg) except the renhe district.The matrix was the main factor affecting the Ni content in soil.The Ni contents in Mangoes among West district,Yanbian county and Renhe district were 0.80,0.66,0.60 mg/kg(of dry matter) respectively,and there were a positive relationship between the average contents of Ni in mango and the corresponding soil.
