Abstract

Abstract

River sediments are the transporters of pollutants. In this study, the effects of sediments particle size on hydraulic transport, content distribution, and speciation of arsenic in arsenic-bearing mine river were studied. The results showed that arsenic pollution was prominent in river sediments of the mine area; particle size affected not only the distribution and speciation of arsenic in various sediment particle size fractions but also their transport in water environment. The sediments were mainly composed of coarse sand and medium sand in the upstream and middle and upper reaches. In the upstream reaches, arsenic content in the sediments was 18.53 mg/kg, which mainly came from the primary minerals and existed in stable forms, such as well-crystallized hydrous Fe and Al oxides and residual. The content of arsenic reached 3492 mg/kg in the middle and upper reaches, which mainly came from oxide dissolution of arsenic-bearing ore and some original mineral. The amorphous and poorly-crystalline hydrous oxides of Fe and Al and residual were the main existing forms in coarse sand and medium sand components(73.90%), accounting for 83.71%, 83.82% of the total arsenic content, respectively. In fine sand, very fine sand and silty sand, the specific adsorption and amorphous and poorly-crystalline hydrous Fe and Al oxides were the main constituents, accounting for 58.72%, 58.51% and 73.10% respectively. The arsenic contents were still 371, 247 mg/kg in the sediments from middle and lower reaches of 2 km and 4 km away from the mine. The sediments existed mainly in fine sand, extremely fine sand and silt-sand, and predominant forms of arsenic were the specific adsorption and amorphous and poorly-crystalline hydrous Fe and Al oxides. Arsenic in the component less than 0.25 mm(fine sand, very fine sand, silted sand) was 1.5 times of that of the coarse sand component, and fine grain sediments played a leading role in the hydraulic transmission of arsenic. Therefore, the ecological control and soil and water conservation in the upper and middle reaches and the ecological dredging and rehabilitation of sediments in the downstream reach should be strengthened.
