Development of an automated trace analyser and a novel passive sampling device for the monitoring of ammonia in marine environments

Abstract

Ammonia is commonly used as an indicator of water quality, to assess the impacts of anthropogenic activity on ecosystem function and health. Water quality assessment often relies on the use of expensive equipment requiring a high degree of operator skill, or periodic, discrete, manual sampling and laboratory-based analysis, which is laborious, costly and without the guarantee that episodic pollution events will be detected. Low-cost, portable and/or field-deployable analytical tools are required to overcome this challenge. Hence, research conducted in the context of this thesis involves the development of novel analytical tools for the monitoring of ammonia in marine waters, covering both ac..
