This assignment involves reviewing a comprehensive list of academic papers and research articles related to aquatic plant studies, wetland engineering, and environmental science. The papers cover topics such as the use of aquatic plants in wastewater treatment, heavy metal accumulation in natural and constructed wetlands, and the role of submergent macrophytes in domestic greywater treatment. Additionally, the assignment includes studies on phytoremediation, biosorption, and the application of root zone method for treating high-strength abattoir waste. The research highlights the potential of aquatic plants and wetland systems in addressing environmental issues such as water pollution and heavy metal contamination.
