PhD thesis: Rapid Quantification of Nitrate/Nitrite Concentrations in Freshwater: Enhancement of the ‘Diffusive Gradients in Thin-films’ Methodology
Supervisors: Professor Louis Schipper, Dr Adam Hartland, Professor Bill Henderson, Dr Gerald Rys (Ministry for Primary Industries)
To understand the relationship between land management decisions and water quality, Thomas’ PhD seeks to test diffusive gradients in thin-films (DGT) for the measurement of nitrate/nitrite, and furthermore enhance this methodology so that in-field analysis may be undertaken. DGT overcomes the major limitations of grab sampling, the current measurement technique, by addressing the high variability of nitrate/nitrite. DGT provide time integrated concentration data, are inexpensive, and easy to use.
