Microplastics in saltmarshes: developing extraction methods and examining past accumulation
… and providing habitats for a diverse range of biota. However, the sources and accumulation of microplastics on saltmarshes have not yet been subject to detailed research. These environments have the potential to resolve the temporal evolution of plastic pollution since production began, …

EXPLORING THE ECOSYSTEM SERVICE VALUE AND THE IMPLEMENTATION OF AN ECOSYSTEM SERVICE POLICY APPROACH IN A NORTHERN UK CITY.
This project aims to identify and engage two main target groups within the Liverpool City Region (LCR): key decision-makers and the public living within LCR. Both are stakeholders within the commentary surrounding green infrastructure within the region. The project broadly aims to explore …

An investigation into control strategies for activated sludge wastewater treatment plants.
The activated sludge process is widely used throughout the world for the treatment of wastewater from domestic and industrial users. This process is not normally efficiently controlled and hence increasingly important financial incentives and environmental considerations exist for improving the …

Kajian pemboleh-pemboleh ubah yang mempengaruhi aras pengetahuan, tindakan dan kesedaran murid sekolah rendah di Johor terhadap isu alam sekitar
… in this research is about primary school pupils’ environmental awareness which has yet to achieve the prescribed objectives despite the implementation of cross curriculum environmental education which has been implemented in 1988. This research was carried out to (i) identify teachers’ views about …

Examination of hydrated and accelerated carbonated cement-heavy metal mixtures
… (TG). Thermodynamic modelling using a geochemical code, PHREEQC, and the edited database, was carried out to elucidate the chemical reactions occurring in cement/heavy metal systems. Heavy metals acted as accelerators for hydration of CaO, CaS and Portland cement except that Zn2+ …

Development of maritime logistics system to support marine and fisheries integrated centres in small island and boundary areas
The geographical configuration of the Republic of Indonesia is an archipelago with most of its inhabitants living in the western region, especially in Java and Sumatra, on the contrary, the population in the eastern region, especially on the island of Papua, is quite low. This results in uneven …

Biodiversity Assessment: moving towards an evidence-based index for biodiversity offsetting
… takes a scientific and pragmatic approach to bridge the gap between empirical approaches to biodiversity assessment and the practical, often subjective, methods used by practitioners. Although commonalities among methodologies exist, systematically reviewing the state of the art, revealed a …

Development of a correction approach for future precipitation changes simulated by General Circulation Models
Producing reliable estimates of changes in precipitation at local- and regional-scales remains an important challenge in climate change science. Statistical downscaling methods are often utilised to bridge the gap between the coarse resolution of General Circulation Models (GCMs) and the …

Environmental impact of mine drainage and its treatment on aquatic communities
… of eight Welsh streams impacted by mine drainage is used to discern the effects of water and sediment related variables and elucidate the most important variables in the impact of mine pollution on freshwater macroinvertebrate communities. The implications of this are to be considered for …

Imaging and analysis of natural and manufactured nanoparticles
… nanomaterials (NMs) became a potential, but largely unknown, risk to human health and the environment. Carbon based NMs including carbon nanotubes (CNTs) and fullerenes are an important class of NMs and are further studied in this thesis. Potential fate and behaviour of single-walled CNTs …

Towards understanding the fate of perfluoroalkyl compounds (PFCs) within urban environments: implications for human exposure.
… were found to be similar to those from France, Germany, USA, Canada and Australia and much greater than from homes in Kazakhstan and Thailand. Concentrations of EtFOSA were significantly higher in house dust samples from Australia compared to the UK, and were raised in all other countries. The …

Algal resource depression by macro-invertebrate herbivores in a chalk stream: An empirical approach
Herbivory is a globally important ecosystem function, occurring in all major biome types; including benthic freshwater habitats. Algal biofilms and their herbivore consumers are therefore important components of stream food webs. However there is relatively little empirical data quantifying the …

The impacts of silver nanoparticles on planktonic and biofilm bacteria
Nanoscale silver particles represent a new generation of cost-effective antibacterial technologies. Due to the increased manufacturing and use of silver nanoparticles (Ag NPs) in consumer goods their release and accumulation into the environment is highly likely but their fate, behaviour and …

Nano- to catchment-scale investigations of metal transport processes in mining-impacted river systems
… by: assessing the role of river catchment geomorphology in metal storage; quantifying metal sources across streamflow conditions; and investigating the metal-bearing nanoparticle flux in the river water. This study investigated metal dispersion at the Nant Cwmnewyddion and the Nant Magwr, …

Relative sea level, sediment supply and barrier dynamics as driving mechanisms of Holocene coastal change.
The combined effects of climate change and population pressure lead to regional and local coastal responses that pose major challenges for the future resilience of coastal landscapes, increasing the vulnerability of communities, infrastructure and nature conservation interests. Improving …

Cave pollen taphonomy in Kurdish Iraq
… factors on the composition of the pollen assemblage, with special reference to the problem of the Neanderthal ‘Flower burial’ at Shanidar Cave, Kurdish Iraq. Limited systematic taphonomic work has been done in cave environments, with most of the studies on an ad hoc basis. However, the number of …
