摘要:Abstract(#br)Pedotransfer functions (PTFs) have been developed to estimate soil fine fraction bulk density (BD FF ) using the relationships with soil organic carbon content (SOC) and particle size distribution. Current PTF's overlook the influence of lithology on BD FF estim...

摘要:Abstract(#br)More than 100 million people in Asia are presently exposed to groundwater with arsenic (As) concentrations exceeding the World Health Organization standard of 10 μg L −1 . Arsenic contaminated groundwater within basins of the central portion of the Yangtze River...

摘要:Abstract(#br)The storage and flux of carbon from soils, the planet's third largest carbon pool, strongly influence the global carbon cycle and are essential, but poorly constrained, parameters for global climate models. An estimated 40% of all soil carbon is stored as inorga...

摘要:Abstract(#br)Atmospheric concentrations of the powerful greenhouse gas nitrous oxide (N 2 O) have increased dramatically over the last 100 years, and part of these emissions come from streams and rivers. N 2 O production has been more carefully studied in soils, but runoff of rea...

摘要:Abstract(#br)Mekong River Delta sediment bears arsenic that has been released to groundwater under anaerobic conditions over the past several thousand years. The oxidation state, speciation, and distribution of arsenic and the associated iron bearing phases are crucial deter...

摘要:Abstract(#br)Millions of people in the deltaic regions of S/SE Asia regularly consume As contaminated groundwater. Arsenic persists within these groundwaters despite being flushed by several pore volumes of recharge, indicative of an in situ solid phase source. Despite the i...

摘要:Abstract(#br)Many islands throughout SE Asia are experiencing rapid development and land-cover conversion that potentially threaten sensitive coastal ecosystems, such as seagrasses, through increased loading of sediment and nutrients originating from disturbed catchments dra...

摘要:Abstract(#br)To advance understanding of hydrological influences on As concentrations within groundwaters of Southeast Asia, the flow system of an As-rich aquifer on the Mekong Delta in Cambodia where flow patterns have not been disturbed by irrigation well pumping was exami...

摘要:Abstract(#br)Arsenic is contaminating the groundwater of Holocene aquifers throughout South and Southeast Asia. To examine the biogeochemical and hydrological processes influencing dissolved concentrations and transport of As within soils/sediments in the Mekong River delta,...

摘要:Summary(#br)Annual total suspended solid (TSS) loads in the Mae Sa Catchment in northern Thailand, determined with an automated, turbidity-based monitoring approach, were approximately 62,000, 33,000, and 14,000 Mg during the three years of observation. These loads were equi...
