Indoor microenvironments can have a relevant contribution towards the total exposure to pollutants. The biomarkers of exposure and effect were analysed in general population, to evaluate the impact of VOCs, PAHs and tobacco smoke exposure in everyday life. We designed a model fo…

This thesis explores urban smoke and its nuisances in Georgian England, especially focusing on the period, 1800-1830. During this period, a number of English towns experienced accelerated industrialisation and many of them first experienced air pollution. In 1821, Michael Angelo…
This study used magnetite (Fe3O4) nanoparticles (NPs), mesoporous silica coated magnetite NPs (SCMNPs) and thiol functionalised silica-coated magnetite nanoparticles (SH-SCMNPs) for Hg(II) removal and recovery from water. The Fe3O4 NPs were prepared via conventional co-precipita…
Contamination of aquatic environments via anthropogenic release of metals is an increasing global environmental concern. The greatest concerns exist within estuarine and harbour environments, where point and non-point metal sources are prevalent. Historically, monitoring program…
The integration of offshore wind farms through Multi Terminal DC (MTDC) networks into the GB network was investigated. The ability of Voltage Source Converter (VSC) High Voltage Direct Current (HVDC) to damp Subsynchronous Resonance (SSR) and ride through onshore AC faults was s…
Future energy supply infrastructure schemes for the built environment are set to consist of a diverse mix of distributed generation technologies, increasingly stringent local emissions reduction targets, and potentially complex ownership structures. This thesis presents a new mo…
This thesis presents work carried out to further the understanding of the use of waste Acid Mine Drainage (AMD) solids to remove phosphorus from wastewaters. AMD can result in serious pollution and so is often treated by the Coal Authority in the UK the resultant solids being a …
Due to their high swelling ability, high water retention capacity and low permeability, compacted bentonites have been considered as a key component of cover lining systems for storage of low and medium level toxic wastes and as barrier and backfilling materials for long-term sa…
The most common technique for carbon dioxide removal from gaseous streams is amine scrubbing, a proven technology in the oil and gas industries. The use of this route in coal fired power plants is not fully understood and the likelihood of solvent degradation is high. Decreased …
The key question this thesis aims to address is to what extent can micro-generation sources contribute to the carbon emission reduction targets set by the UK government. The operational emissions of micro-CHP capable micro-generators were examined against the UK grid electricity…
Research has been undertaken to develop new yttria slurry systems for use in mould face coats for investment casting TiAl alloy, solving the pre-gelation problems of commercial yttria slurry systems to increase slurry life. Meanwhile, the new face coats should also have excellen…
There has been a great deal written about the difficulties faced by small and medium-sized enterprises (SMEs) compared to larger businesses. SMEs face difficulties complying with environmental legislation, particularly because of the amount of complex law. This can result in the…
Results are presented from sets of field and laboratory experiments conducted to measure and quantify the Hydraulic Residence Time Distribution in treatment ponds containing vegetation. The field measurements were taken in the Lyby field pond (Sweden) with complementary experime…
The world is facing the challenge of global warming and environment protection. On the other hand, the demand of electricity is growing fast due to economic growth and increase in population. Since the growth in demand is also a heavy factor in energy equations, then the renewab…
Buses, the main form of public transport in many urban areas, are considered as an efficient and environmentally friendly transport mode because of their high passenger capacity. The concept of bus priority was originally proposed to protect buses from urban traffic congestion s…
This thesis focuses on modelling the degradation of particles in gas-solid fluidised beds. Modelling is performed by using a coupled approach where the gas phase is treated as a continuum and the solid phase is represented by individual discrete particles, using the discrete ele…
Accelerated carbonation involves exposing a material to a concentrated atmosphere of carbon dioxide, and can be used to treat hazardous wastes and soils and create new construction materials. The present work examines the use of accelerated carbonation to reduce the hazardous pr…
Local weather data (wind direction, wind speed and temperature) from meteorological stations and daily synoptic data have been examined in relation to airborne particulate material (PM10) concentrations recorded at 17 pollution monitoring sites throughout Kent for the period 200…
Hydrocarbon selective catalytic reduction (HC-SCR) is emerging as one of the most practical methods for the removal of nitrogen oxides (NOx) from light-duty-diesel engine exhaust gas. In order to further promote the chemical reactions of NOx-SCR by hydrocarbons, an understanding…
