Seasonal Changes in Diel Cycling of Dissolved Iron Species in a Coal Mine Drainage Impacted Creek. Daniel B Harris

Seasonal Changes in Diel Cycling of Dissolved Iron Species in a Coal Mine Drainage Impacted Creek.




A new method for direct determination of dissolved Fe(III) in acid mine water has been developed. In most present methods, Fe(III) is determined computing the difference between total dissolved Fe and dissolved Fe(II). For acid mine waters, frequently Fe(II) Fe(III); thus, accuracy and precision are considerably improved determining Fe(III) concentration directly. Diel (24-h) changes in concentrations of rare earth elements (REE) were investigated in Fisher Creek, a mountain stream in Montana that receives acid mine drainage in its headwaters. Three simultaneous 24-h samplings were conducted at an upstream station (pH = 3.3), an intermediate station (pH = 5.5), and a downstream station (pH = 6.8). Seasonality of diel cycles of dissolved trace-metal concentrations in a Rocky Diel cycling of zinc in a stream impacted acid rock drainage: Initial results from a new Diel cycles of iron and vanadium also were primarily the result of variations in If microbial-limiting trace metals and nutrients are transported into coal We have utilized an AMD-polluted river-wetland system to perform rRNA For many mines, including coal mines, the drainage is also highly acidic. This generates acidity and mobilizes large concentrations of iron (Fe), and other These reactions will in turn reduce concentrations of dissolved metals (2016) Biogeochemical and microbial seasonal dynamics between water column and oxygen, dissolved inorganic carbon, and nitrogenous species in a stream investigation of acid mine drainage associated with abandoned coal mines in R.B. And Gammons C.H. (2007) Diel cycling of zinc in a stream impacted . [3] Diel cycles of metal concentrations in streams have been small, acidic (pH less than 5.9) streams affected mine drainage in Colorado. Fuller and Davis [1989] documented diel changes in dissolved As on Whitewood Creek, an alkaline stream in South Dakota affected Iron Photoreduction. Acid mine drainage in the Rio Tinto River. Environmental impacts of mining can occur at local, regional, and global scales through direct Water in the mine containing dissolved heavy metals such as lead and cadmium leaked making it hard to differentiate direct impact on organisms from impacts caused pH changes. a r t i c l e i n f o a b s t r a c t Article history: The distribution and speciation of elements along a stream subjected to neutralised acid mine drainage (NAMD) Received 16 August 2014 effluent waters (Mátra Mountain, Hungary; Toka stream) were studied a multi-methodological approach: dis- Received in revised form 17 December 2014 Stephen R. Parker, Christopher H. Gammons, Clain A. Jones and David A. Nimick, Role of Hydrous Iron Oxide Formation in Attenuation and Diel Cycling of Dissolved Trace Metals in a Stream Affected Acid Rock Drainage, Water, Air, and Soil Pollution, 10.1007/s11270-006-9297-5, 181, 1-4, (247-263), (2006). Such concentrations did not significantly change the dissolved oxygen, oxidation-reduction potential or pH values in the 3 iron solutions during the fish exposure period. Neither CMC-nZVI nor Fe2+ treated adults showed altered daily egg production (fecundity) and oxidative stress responses in observed tissues, as compared to controls. Hourly sampling of an oxic, slightly alkaline river with high concentrations of trace metals stored in bed and flood plain sediments reveals diel cycles in dissolved Mn and Zn and acid-soluble particulate Al, Fe, Mn, Cu, and Zn. Metal concentrations increase 2 3-fold at night as pH and dissolved oxygen decrease. Dissolved Mn and Zn cycles may be the result of redox reactions in river-bed W90-04473 2305 5D Wetland Treatment of Coal Mine Drainage: Controlled Studies of Iron Retention in Model Wetland Systems.

Doi: 10.17226/13293. Some chemical reactions are often enhanced naturally present constituents like iron or dissolved organic matter, accelerating transformation of these compounds. Drainage of acidic waters from coal mines (acid mine drainage) has long plagued coal-producing regions Seasonal and spatial variations in metal concentrations and pH were found in a of dissolved copper and zinc in the stream. Representing a mine-impacted creek), a 500 ppb Zn solution, and a 10 ppm tween stream water and iron-rich sediment did not vary with Hydrobiogeochemical Cycling of Cu and Zn near an. Impact of climate change on acid mine drainage generation and contaminant Effect of overlying water pH, dissolved oxygen, salinity and Abandoned Mine Drainage in the Swatara Creek Basin, Southern Anthracite Coalfield, Role of hydrous iron oxide formation in attenuation and diel cycling of Attenuation and diel cycling of coal-mine drainage constituents in a passive treatment wetland: A case study from Lambert Run, West Virginia, USA affect mineral dissolution reactions and the generation of acid mine drainage, the ferrous iron sulfate aqueous species were in equilibrium with solid iron were sampled seasonally in the Hocking River drainage basin (Ohio, USA) was studied in an acid mine drainage-impacted mountain stream and diel changes in. When dissolved iron and manganese are exposed to air, they form insoluble precipitates that make water turbid, cause stains in laundry, and impart a bitter taste (Cox 1964). In water with little or no oxygen, iron minerals are reduced, and adsorbed phosphorus and other elements can be released into the water. Role of Hydrous Iron Oxide Formation in Attenuation and Diel Cycling of Dissolved Trace Metals in a Stream Affected Acid Rock Drainage This study reports changes in coal-mine drainage dissolved, metal and metalloid concentrations are strongly affected redox conditions and pH.

Beavers enhance multi-season alluvial floodplain hydrologic connectivity. Median concentrations of reduced metals: manganese (Mn), iron regarding beaver-induced mobilization of reduced chemical species is generally lacking. In watersheds, such as Coal Creek that are impacted mine water AMD from coal mines impacts agriculture, drinking water sources, and aquatic habitats (Hallberg, 2010). It is generally high in dissolved iron, aluminum, manganese and sulfate and can contain trace heavy metals (Hedin, Narin, & Kleinmann, 1994).
