Development of a biosensor/bioassay for measuring nutrient pollution (2005–2007)
Monitoring nutrients in water bodies is a key challenge. To date no routine method allows continuous or time integrated monitoring of nutrients. Consequently it is generally limited to grab sample nutrient analysis or chlorophyll monitoring. This collaboration aims to develop a novel biosensor allowing continuous monitoring of nutrients using growth of standard algae in semi-controlled conditions. Nutrients enter the growth chamber via diffusion through a membrane. The project includes selection of suitable algae calibration evaluation and validation studies. The outcomes will provide a new tool for effective evaluation of nutrient input which is essential for appropriate management of water pollution.
