| 摘 要： | 采用Tessier连续提取法、BCR连续提取法和Leleyter连续提取法,研究广州"南肺"果园土壤Hg和As的形态分布和生物可给性。结果表明,果园土壤Hg和As形态分布都以残渣态为主;3种方法的土壤生物可给性分析均表明,Hg和As生物可利用态的含量较少;生物不可利用态是主要形态,其次是潜在可利用态。

| Abstract: | Fractions of heavy metals mercury and arsenic in an orchard soil were analyzed with Tessier′s method,BCR′s method and Leleyter’s method.The results showed that residual fraction of heavy metal was the predominant fraction.As for bioavailability of heavy metals,the percentages of bioavailable fractions were lower than those of other fractions in three analysis methods. |
