摘要

摘要: 珠江三角洲代表性土壤浅层和深层样品测试数据表明,珠江三角洲土壤中存在较严重且分布广泛的氟元素污染,土壤氟的高含量区分布于冲积平原,显著地受海相沉积背景控制,与海相沉积密切相关,氟含量从地表到地下1.5~2.5m均较高,但含量变化较小。高氟含量区分布与全新世海侵范围基本一致,两者具有较好的耦合关系,表明该区氟元素污染属于自然作用引起的土壤污染,与人类经济活动关系不大,推测这是由于海水中氟元素在土壤富集的结果,需要采取相应措施进行土壤中氟元素污染的回避、防治和修复。

Abstract: On the basis of the test data of representative soil samples from shallow and deep soil in the Pearl River delta, fluorine elements have seriously and widely polluted the soil. The high concentration regions of fluorine are distributed in the alluvial plain, controlled by marine sedimentation. The fluorine concentra-tions are high,and change little from surface to 1.5-2.5 m subsurface. The high concentration regions were coupled with marine invasion ranges in the Holocene, indicating the fluorine pollution was caused by natural factors in the Pearl River delta rather than by human economic activities. We need to take corre-sponding measures to avoid, prevent and repair the fluorine pollution in soil.
