Abstract:Stable isotope values of δ 15 N NOd 3 and δ 18 O NOd 3 of dissolved nitrate (NO 3 ) are commonly used to identify the occurrence of denitrification as there is a progressive increase of δ 15 N NOd 3 and δ 18 O NOd 3 values accompanied by a decrease in NO 3 concentration. Thus, denitrification results in a positive trendline on the dual plot of δ 18 O NOd 3 versus δ 15 N NOd 3 . The combination of two trendlines with different slopes provides the "typical expected isotopic range of denitrification (TEIRD)" on t… Show more
