Something very similar is happening in the atmosphere. Acidic sulfur emissions from power plants have been rapidly declining over the past decade, and the neutralizing base – ammonia – is emitted from...
This research examined the environmental fate of two polycyclic aromatic hydrocarbons (PAHs), naphthalene and phenanthrene, under in situ, sulfate-reducing conditions, and the composition of the micro...
Acid mine drainage (AMD) is an acidic, iron-rich leachate that causes the dissolution of metals. It constitutes a worldwide problem of environmental contamination detrimental to aquatic life and water...
The atmospheric concentrations of nonsea-salt (nss) SO4 2– and trace elements (As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Sb, Se, V, and Zn) were measured for aerosol samples collected concurrently at ten site...
Chemistry of surface waters from the Tateyama caldera known as a site of frequent landslides in northern central Japan was investigated to obtain the relationship between their geochemical characteri...
We analyzed rainwater collected from Huanjiang, China, between June, 2007 and May, 2008, with the aim of understanding the origin of the acid rain and its potential impacts on CO2 uptake by carbonate...
The Lower Murray Reclaimed Irrigation Area (LMRIA) comprises approximately 5,000ha of flood-irrigated agricultural land located on the floodplain of the River Murray between Mannum and Lake Alexandrin...
Sea level has risen approximately 1.2 mm/year over the last 100 years (Hennessy et al., 2004) and is predicted to rise up to 80 cm by 2100 relative to 1990 sea levels (IPCC, 2007). The number of extre...
Significant quantities of sulfidic sediments have been reported to have recently accumulated in inland wetlands of Murray Darling Basin due to a combination of long periods of inundation and the entra...
Thermochemical reduction of MgSO4 by natural gas was carried out in the presence of water. Chemical and carbon isotopic variations were characterized with microcoulometry, gas chromatography, FT-IR, ...
Atmospheric aerosol samples were collected from 1993 to 2003 at Tsuruoka, Japan, a coastal area on the Sea of Japan. Concentration of water-soluble chemical components and sulfur isotopic ratios of su...
We report the chemical composition of groundwaters—including the first data on the sulfur isotopic composition of dissolved sulfate—from the volcanic aquifers of Mt. Vulture, one of the most important...
This study was conducted to assess the effects of organic and inorganic copper on performance in growing pigs. A total of 100 pigs, average age 63 d and initial body weight 21.46??.13 kg, were assigne...
We use a 3-D global chemical transport model (GEOS-Chem) to interpret aircraft observations of nitrate and sulfate partitioning in transpacific dust plumes during the INTEX-B campaign of April–May 200...
The cloud condensation nuclei (CCN) properties of ammonium sulfate particles mixed with organic material condensed during the hydroxyl-radical-initiated photooxidation of isoprene (C5H8) were investig...
