Abstract

Safe water quality is critical to human health, biodiversity, and ecology. The deterioration of water quality has become a widespread problem in the Chao Phraya River and for the communities living along the canals. Testing of the river water characteristics, such as dissolved oxygen, biochemical oxygen demand, and coliform bacteria, have been inferior to the standard established by the Pollution Control Department (PCD, 1994). There is an urgent need to further explore the health risks associated with this environmental health problem and the feasibility of possible bioremediation strategies. The goal of this study is to determine how the urban environment may affect salinity in the canals west of the Chao Phraya River. This study will also explore the potential of Avicennia officinalis mangroves to serve as biofilters and bioremediate the water quality. I hope to highlight the adaptive features mangroves have developed, such as salt secretion via their leaves, compartmentalization of salts, osmoregulation, and salt exclusion through their roots to survive under high salinity conditions (Krishnamurthy et al., 2017; Parida & Jha, 2010). Findings will be used to advocate for the health of communities living along the Chao Phraya River, structural change to better support ecological biodiversity, and greater care for the environment.
