Water is considered as one of the most important natural resource. Water is the most essential asset of our day-to-day life as it is used for drinking, in agricultural and industrial processes.
Rivers are the main water sources for drinking, irrigation, recreational and industrial uses in many inland areas around the globe.
Pollution of the aquatic environment and ubiquitous water quality deterioration is of major concern. Modern wastewater treatment systems include a complex of different physical.
The release and accumulation of organic and inorganic pollutants in the environment by natural and anthropogenic sources have led to serious environmental problems.
Environmental issues nowadays include the presence of contaminants in waters that are increasing in numbers and classes of chemicals. The environmental and human health will always depend on the protection of the air, waters, and soil.

Jonathan Y.S. Leung earned his bachelor degree (BSc, 1st class honours) and master degree (MPhil) at City University of Hong Kong. He was awarded International Postgraduate Research Scholarship (IPRS) and Australian Postgraduate Award (APA), and then studied for his doctorate degree (PhD) at the University of Adelaide, Australia. He is a marine ecologist with broad research interests. In particular, he is interested in how environmental factors, especially pollution and climate change, influence marine invertebrates from physiological level to community level. Apart from marine ecology, he is collaborating with Guangzhou University in China to study environmental chemistry and pollution caused by anthropogenic activities. Over the last few years, his research areas have been focusing on: (1) Impacts of hypoxia, ocean acidification and warming on the fitness and survival of marine invertebrates (e.g. polychaetes and molluscs), (2) Ecological functions of macrobenthic community in mangrove ecosystems following habitat modifications, (3) Environmental monitoring and risk assessment of pollutants (e.g. heavy metals, PAHs, PBDEs, etc.) in different environmental media, and (4) sewage treatment technology.
