Thesis

Development and evaluation of a novel diffusive gradient in a thin film technique to measure arsenic and selenium speciation and bioavailability in natural waters.

Description

Arsenic and selenium are toxic trace elements that pose a significant threat to both aquatic biota and humans. The largest sources of As and Se contamination in Australia are from coal fired power plants and metal smelters. A novel diffusive gradient in a thin film passive sampling technique will be developed and compared with bioaccumulation in aquatic organisms to characterise the bioavailable fractions of As and Se and relate them to toxic effects.
