氟硅产业园区植物及土壤对氟的富集能力
|
摘要
[目的]探究氟硅产业园区植物及土壤对氟污染物的富集能力。[方法]采用连续浸提法对氟硅产业园区82个采样点的土壤及植物叶片中不同形态氟含量进行测定,并对其吸收氟污染物的能力进行评价。[结果]产业园区植物叶片总氟平均含量为(943.45±23.43)mg/kg;土壤总氟平均含量为(865.07±19.25)mg/kg。植物叶片中可还原态氟与离子交换态氟呈显著正相关(r=0.680 5),土壤中水溶态氟、铁锰结合态氟与其他形态氟之间具有显著相关性,而植物叶片总氟含量与土壤总氟含量无显著相关性。[结论]超累积氟的植物有山茶树、枫杨、香樟等,对土壤氟富集能力较强的植物有苎麻、小叶樟、夹竹桃等。
[Objective]To evaluate the absorption and purgation of plants and soil to fluorine pollution in fluorion silicon industrial park.[Method]The different forms fluorine of soils and leafs of 82 sampling sites in the fluorine silicon industrial park were determined. [Result]The average concentration of fluorine was( 943.45± 23.43) mg/kg. The average fluorine concentration of soil was( 865. 07 ± 19. 25) mg/kg.There was a positive correlation between the reducible and exchangeable fractions in leaves and a significant correlation among the water-soluble( r = 0.680 5),Fe/Mn-F and other forms of fluorine in soils. Nevertheless,there was no significant correlation of total fluorine in leaves and soils. [Conclusion]The super-rich fluorine-contaminated plants were screened out,such as Pterocarya stenoptera,Salix babylonica and Pyracantha fortuneana,et al. And several species with higher soil fluorinated concentration ability were screened out,such as Boehmeria nivea,Deyeuxia langsdorffii,Nerium indicum,et al.
