More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new Duke University study finds that high levels...
Our automatic digestion device is applied in determining the quantity of organic carbon in the soils/sediments. Its operation process is simple. The reaction conditions are optimized; the complex pret...
Sub-bottom profiling was conducted in the Japanese Exclusive Economic Zone (EEZ) around Minamitorishima Island, western Pacific Ocean, to investigate the features and distribution of mud rich in rare...
Much of what is known about the evolution of Antarctica's cryosphere in the geologic past is derived from ice-distal deep-sea sedimentary records. Recent advances in drilling technology and climate pr...
An investigation of mercury (Hg) in soils and stream sediments was conducted to understand the impact of urbanization on Hg deposition and accumulation on the upper west fork of the White River waters...
Pore-water exchange caused by ebullition of small oxygen bubbles produced by microalgae in the surface layer of sand sediment at St. Joseph Bay (SJB), Gulf of Mexico, was contrasted with ebullition o...
Molecular distribution and compound-specific hydrogen isotopic ratios (δD) of n-alkanes in shallow-water surface sediments from the Chaka salt lake and from various terrestrial plants in the surround...
Trace metals in the surface sediments were measured to investigate the spatial distribution and annual variations of metals (Cr, Co, Ni, Cu, Zn, As, Cd, Pb, Hg) and to evaluate the pollution status f...
The Daliao River System (DRS) estuary in the Liaodong Bay has a highly industrial, urbanized, and agricultural catchment. The objective of this study was to investigate the multi-elemental geochemist...
An apparent temporal increase in Mn and As in a thin surface layer (ca. 2 cm) of sediments in Lake Biwa, Japan, was observed by comparing depth profile data from 1977 and 2009. By our estimation, sev...
The concentrations of the herbicide Diuron and algaecide Irgarol in the Seto Inland Sea, Japan, were assessed for October 2008 and October 2009. Overall, 29 seawater, sediment and plankton samples we...
The distribution of heavy metals in recent sediments deposited along the Tietê River, a highly polluted river in southeast region of Brazil was studied. Around the metropolitan area of São Paulo...
Monosaccharide compositions were determined for a sediment core (RD-1) collected from a tropical wetland, Rawa Danau, West Java, Indonesia (location 6°11′ S and 105°59′ E) to assess the sources and d...
The ornithogenic sediments in the maritime Antarctic are good archives for studying the changes of historical penguin population. Rare earth elements (REEs) along with biological and lithophile eleme...
To constrain the origin of fluoride and arsenic contamination of groundwater in Kalalanwala, Punjab, Pakistan, the geochemical and mineralogical characteristics of the aquifer were studied. Subsurface...
