PARTICLE SIZE AND OCCURRENCE CHARACTERISTICS OF ARSENIC IN RIVER SEDIMENTS OF ARSENIC-BEARING MINE AREAS

  • 摘要: 矿区河流沉积物是重金属污染物的迁移载体。研究了某含砷矿区河段沉积物砷含量分布、赋存形态及粒径对沉积物中砷水力传输的影响机制。结果表明:矿区河流沉积物中砷污染问题突出;沉积物颗粒大小不仅影响砷在沉积物组分中的分配与赋存形态,还会影响水环境中砷的传输。在矿区上游和中上游河段,沉积物均以粗砂、中砂组分为主,上游河段沉积物中砷含量为18.53 mg/kg,主要来源于原生矿物,以结晶水合铁铝氧化物结合态和残渣态等稳定形式存在。中上游河段沉积物中砷含量达到3492 mg/kg,主要来源于采矿活动导致矿石中砷的氧化溶出和部分原生矿物,粗砂、中砂组分(73.90%)中砷以弱结晶水合铁铝氧化物结合态和残渣态为主,分别占总砷含量的83.71%和83.82%,细砂、极细砂、粉砂中砷主要以专性吸附态和弱结晶水合铁铝氧化物结合态存在,分别占总砷含量的58.72%、58.51%和73.10%。在距离矿区2,4 km处的中游、下游河段沉积物砷含量仍有371,247 mg/kg,以细砂、极细砂、粉砂为主,其中专性吸附态和弱结晶水合铁铝氧化物结合态砷是主要形态;沉积物<0.25 mm(细砂、极细砂、粉砂)组分中砷含量是粗砂组分的1.5倍,<0.25 mm细颗粒沉积物对砷的水力传输起主导作用。因此,应加强废弃含砷矿区河流生态治理和水土保持,防止细泥沙入水;同时,加强下游河段沉积物生态疏浚和修复治理,防止沉积物中砷的再释放。
