Environmental Quality Standards and effluent discharge consents for metals.
The objective of this project is to investigate the role of complexants in the removal of copper, nickel and zinc during wastewater treatment, and to contribute to the argument for speciation based standards and consents.

The aim of Anna’s research is to make a contribution to the development of a biotic ligand model predicting copper toxicity in estuaries and seas. In order to achieve this objective it is necessary, firstly, to identify the main challenges that need to be addressed and, secondly, to develop a strategy of research that allow investigating the identified problems. The first step was indeed a review of the information available in the literature. This investigation underlined two main topics of research: a) The interactions between organic matter and copper toxicity, with particular regard to the effects of different types of organic matter, displaying different complexation capacities; b) The influence of physiology on copper toxicity and their interactions at variable salinities.

The aim of this study is to develop a robust procedure for hazard assessment and risk characterization for indirect potable reuse (IPR) schemes, focussing on chemical contaminants of concern, and related to modelling of the catchment, which will help ensure that the potable supply is chemically safe and meets international (WHO) and national guidelines.

Occurrence and Removal of Emerging Contaminants in Wastewaters
The water industry faces significant challenges over the coming decades, with requirements to meet increasingly stringent environmental quality targets along with increasing pressure to reduce energy use and associated emissions of CO2. Whereby it should be balance between the quality of water or treated wastewater and requirement to reduce CO2 emissions.
This research, being undertaken in collaboration with the UK wate rindustry, will begin with a focus on the impact of dissolved organic matter (DOM) on the partitioning of some model compounds with a range of hydrophobicities., to determine if the prsence of DOM may influence removal on suspended solids. It will then move onot the effect of DOM on toxicity, using EE2 woth DOM, and then the addition of both PFOS and HBCD to detremine if there is any influence from competative binding.
