Chemicals Monitoring and Water Quality
The chemicals monitoring and water quality research group undertakes pure and applied researches to understand the levels and risks of emerging contaminants of global concern. We are interested in mapping contaminants including heavy metals, pesticides, PAHs, EDCs, PPCPs, PCBs in aquatic environment with a view of developing new sustainable materials for their removal. We also desire to understand how changing climate impacts movement, quality and quantity of water.
Our project aims to model sustainable methods for achieving cleaner water, safer and enough food, pollution reduction, ecological and health risk assessment of prevalent chemical contaminants in our aquatic environment.
We work in a broad range of environments: from streams, through agricultural soils, groundwater, rivers and wetlands, to the coastal waters. Due to the interdisciplinary nature of our research, we work with chemists, microbiologists, GIS experts, and social scientists.
Since our laboratory infrastructure is under development, we work with many foreign collaborators to achieve most of our research aims. These include Lancaster Environment Centre at Lancaster University, International Environmental Research Centre at Gwangju Institute of Science and Technology (GIST) South Korea, etc.
Most of our researches and programmes have global relevance and have attracted funding supports from many organisations such as the TETfund, American Chemical Society (ACS), United Nations Office for South-South Co- operation, etc.
