Transformations of phosphate (Pi) in different soil fractions were tracked using the stable isotopic composition of oxygen in phosphate (δ 18 O p ) and Pi concentrations. Clay soil from Israel was treated with either reclaimed waste water (secondary, low grade) or with fresh water amended with a chemical fertilizer of a known isotopic signature. Changes of δ 18 O p ...
The nitrogen (N) and oxygen (O) isotopic composition (δ 15 N and δ 18 O) of water soluble aerosol nitrate was measured in aerosol samples collected in Eilat, Israel, from August 2003 to November 2004. During this period δ 15 N values ranged from −6.9‰ to +1.9‰ and δ 18 O from +65.1‰ to +84.9‰ and exhibited strong seasonal variability with higher average δ 15 ...
The phosphate oxygen isotopic composition in naturally occurring particulate phosphatic compounds (δ 18 O p ) can be used as a tracer for phosphate sources and to evaluate the cycling of phosphorus (P) in the environment. However, phosphatic compounds must be converted to silver phosphate prior to isotopic analysis, a process that involves digestion of particulate matter in acid. This...
