海南槟榔园土壤重金属含量分布与评价

     

摘要

运用常规分析方法.测定海南不同地区和不同种植年限槟榔园土壤铜、铅、总砷和总汞含量.采用污染指数分析法,评价槟榔园土壤重金属环境污染状况.结果表明,除翰林样区槟榔园区土壤列为Ⅱ级"警戒"土壤质量等级外,其他土壤铜[(18.68±14.25)mg/kg]、铅[(25.27±7083)mg/kg]、总砷[(2089±2.43)mg/kg]和总汞[(0.08±0.07)mg/kg]含量均未超出国家一级土壤环境质量标准.不同地区间,槟榔土壤铜、铅和总坤含量差异显著;不同种植年限间,槟榔土壤铜、铅、总坤和总汞含量差异十分显著.%The soil copper, lead, total arsenic, and total mercury of Areca catechu plantations in Hainan between the different regions and different years of cultivation was measured by conventional analysis methods. Soil heavy metal pollution of Areca catechu plantations was evaluated using pollution index analysis. Soil Cu [(18.68±14.25)mg/kg], lead [(25.27±7.83)mg/kg], total arsenic [(2.89±2.43)mg/kg] and total mercury [(0.08± 0.07)mg/kg] content was within the standards, listed as the first level of soil environmental quality standards, but garden soil of Areca catechu in Hanlin sample plot were listed as grade Ⅱ "alert" level of soil quality. The soil copper, lead, and total arsenic in Areca catechu plantations were very significant difference between different regions. The soil copper, lead, total arsenic and total mercury in Areca catechu plantations were very significant difference between different years of cultivation.
