Sources and fate of nitrate in a groundwater-fed estuary elucidated using stable isotope ratios of nitrogen and oxygen
nitrate oxygen isotope
2014/10/16
We used d15N-nitrate (NO{
3 ) and d18O-NO{
3 to unravel the provenance and fate of NO{
3 in a groundwater-fed
estuary. A total of 13 monthly and two time series surveys were undertaken in the Werr...
Application of an Oxygen Electrode to Evaluate Superoxide Anion-scavenging Ability
Application Oxygen Electrode Evaluate Superoxide Anion-scavenging Ability
2010/9/15
The ability to scavenge superoxide anion radicals (•O2−) was determined using an oxygen electrode. The method is based on the determination of •O2− generated by the reaction of...
