Spatial and temporal variations in copper speciation in ...

Abstract. Copper in estuaries has been an issue of concern for its toxicity to marine organisms. The ability to understand the processes that control copper speciation is a key factor towards achieving an improved assessment of the ecological risk it poses in the marine environment.

Heavy Metals Spatial Distribution Characteristics in a ...

statistics method could accurately analyze the spatial variation of heavy metals and metalloid in the mining area. Over-all, higher concentrations of heavy metals and metalloid were found in the center of both the north and south sides. The content of copper in the south was significantly higher than that in the north due to paddy field land uses.

Spatial variability - Wikipedia

Spatial variability occurs when a quantity that is measured at different spatial locations exhibits values that differ across the locations. Spatial variability can be assessed using spatial descriptive statistics such as the range.Let us suppose, that the Rev z(x) is perfectly known at any point x …

COPPER ISOTOPE TRACERS OF FLUID FLOW AT BINGHAM …

Copper isotope variation in chalcopyrite can be observed throughout the Bingham Canyon Mine and used to understand high temperature mineral processes. At Bingham, copper isotope variation in hypogene minerals (e.g. chalcopyrite) ranges from -0.05 to +1.95‰. Two sections spanning the deposit were chosen to observe spatial variation in

Spatial variability and temporal changes in the heavy ...

Spatial variability of zinc content, expressed as the variation coefficient (v = SD/mean), was as in the case of copper higher in soils of furrows than of ridges, and was generally higher in layer 0–10 cm than 0–30 cm. It was also found that there is no clear time trend in layer 0–30 cm, whereas in layer 0–10 cm, the coefficient of ...

Spatial Distribution and Variation of Heavy Metals and ...

Aug 26, 2010 · Abstract: The spatial distribution and variation of six heavy metals and metalloid in soil of Zhuji Lipu copper mining area was studied using geostatistics approaches combined with GIS. These elements included Pb, As, Cr, Cu, Zn and Ni. The statistical analyses showed that concentrations of these elements were lognormal distribution.
