Dr Mark Scrimshaw

My research has covered a range of topics, encompassing public perception of environmental management, risk in relation to exposure to chemicals and issues of sustainability related to recovery of phosphorus from wastewaters. However, the major focus has been, and remains, the fate and behaviour of chemicals. Research is predominantly laboratory based, and major topics include:

• Emerging contaminants; the evaluation of their environmental impact and approaches for controlling their discharge to the environment.
• The sources, fate and behaviour of organic micro pollutants in sediment and water.
• The fate of contaminants in wastewater treatment processes.
• Cost / benefits of increasing stringency of environmental quality standards.
• Development of analytical methods for the determination of contaminants in the environment and wastewater matrices.

Research Interests

Research Activity

Chemicals in the Environment

With a population of over 60 million in the UK, we deliver to the UK water industry around 3.6 billion tonnes of sewage a year (1½ times the volume of Lake Victoria, the largest of all African lakes) – its treatment presents a huge challenge, exacerbated by the occurrence of often hazardous chemicals. With the addition of urban and agricultural runoff, controlling the water quality of our rivers is a challenge underpinned by meeting statutory standards.

Meeting these standards comes at a cost. Research at Brunel addresses wider issues, such as looking at how we might reduce the concentrations of chemicals in the environment at a time of increasing population and chemical use, alongside the need to reduce CO2 emissions. Alos, of growing interest, what are appropriate standards and control measures and how we might become more intelligent about how we use chemicals and dispose of them.

The toxicity of chemicals in the real world

At present, ecotoxicological studies to determine the concentrations at which chemicals exert a toxic effect are undertaken in pure laboratory water as an exposure medium. However, this water is not representative of that which is present in the environment, where rivers contain dissolved organic matter (DOM) which may reduce the bioavailability of chemicals. Rivers and streams vary widely in DOM concentration as well as DOM characters (e.g., aromaticity), and these features of DOM may produce variation in dissolved concentrations of many chemicals and also in their bioavailability. As a consequence, it is possible that toxicity of chemicals determined in the laboratory may be lower than is the case in the “real” aquatic environment, resulting in the derivation of environmental quality standards (EQS) which are perhaps over protective.

Two research students, Anna de Polo and Cyril Onogbosele are both looking at this topic, Anna investigating environmental factors influencing the toxicity of metals in esturaine environments, and Cyril studing how dissolved organic matter may influence bioavailability and toxicity of organic contaminants, such as PFOS, HBCD and EE2.

Removal of contaminants during municipal wastewater treatment processes

Working with the UK Water Industry, where there remains a requirement to understand how biological wastewater treatment may operated to achieve maximum removal of trace organic and metallic contaminants. At present, projects are focussed in two areas, related to efficiency of processes in removing metals and organic contaminants along with studies into the impact of ligands in influencing the toxicity of metals in wastewater effluents.

Significance of organic ligands in municipal wastewater effluents.

This work, being undertaken in collaboration with Dr Sean Comber at Atkins, is supporting and EngD student, Carlos Constantino and is funded by the EPSRC and Severn Trent Water plc through the Engineering Doctorate programme. It is focussing on the influence of organic ligands in wastewaters on the bioavailability and toxicity of metals, in particular copper, nickel and zinc. The objective of the work is to increase understanding of binding of metals to organic ligands and to influence the debate on the introduction of speciation based environmental quality standards (EQS).

Indirect Potable Reuse: Hazard and Risk prioritisation.

Research being undertaken by Angelina Dominiguez-Chicas in conjunction with the UK Water Industry is evaluating methodology for assessing the hazard and risk associated with chemical contaminants in relation to indirect potable reuse (IPR) schemes. As part of the delivery of potable water, WHO guidelines now highlight the value of the water safety plan (WSP) approach. The project that Angelia is working on involves developing and applying methodologies to evaluate the risk posed by chemical hazards along the water supply chain as part of the WSP for indirect potable reuse schemes.

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.

Anna de Polo

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.

Water Reuse

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.

Cyril Onogbosele

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.

I have been involved in teaching at masters level since 1987 when I taught practical classes on the Public Health Engineering course at Imperial College. Subsequently, as a Research Officer, I was involved in teaching water and analytical chemistry at masters level, initially with 15 hours of lectures a year, which increased to 25 with development of contributions on environmental microbiology and wastewater treatment. I was also responsible for organising and participating in the week long “study tour” for 20–30 MSc students to East Anglia for 5 years.

Course Development

Since arriving at Brunel University, I have been involved in teaching on the MSc programme within the Institute for the Environment. After my arrival in November 2005, I delivered a 15 credit module in “Water Management” the following term. I jointly led in gaining approval for two new MSc programmes, in Environmental Science, the “Pollution and Monitoring” and the “Legislation and Management” programmes. I have been Programme Leader on the Pollution and Monitoring course since 2006. I have also been a Senate Representative involved in the approval of new courses at Brunel University.

External Teaching Duties

I have recently been appointed as an external examiner at UCL on the MSc in Environmental Systems Engineering run by the Department Civil, Environmental and Geomatic Engineering. I am also an external examiner for the MRes in Analytical Chemistry run by the School of Science and Technology at Nottingham Trent University.

I represent Brunel University on the Confederation of British Industry's (CBI) London Climate Change Panel and have been involved in hosting students at Brunel University who were on the Nuffield Science Bursaries scheme.
