Assessment of heavy metal contamination in water, sediments, and Mangrove plant of Al-Budhai region, Red Sea Coast, Kingdom of Saudi Arabia

Abstract

This study investigates the hydrographic parameters and contamination status of zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), lead (Pb), cadmium (Cd), vanadium (V), and nickel (Ni), etc. in surface water, surficial sediments, and mangrove tree tissues (Avicennia marina). Samples were collected from nine sites in Al-Budhai area of Red Sea coast of Jeddah. The trend values of metal contamination factor were Ni (3.23) > Cd (2.99) > Pb (2.86) > Zn (2.69). Translocation factor (TF) of the metals showed Avicennia marina tissues have a dominant role in the phytoremediation process through toxic metal uptake.

Impact of heavy metals on aquatic life and human health: a case study of River Ravi Pakistan

“…These contaminants are of particular concern due to their toxicity, persistence, and bioaccumulation, which pose significant threats to marine life and human health through the food chain (Tao et al, 2012;Briffa et al, 2020). Coastal sediments often serve as the final repository of contaminants originating from multiple sources (e.g., riverine input, atmospheric deposition, and direct industrial discharges) and usually act as important sinks for trace elements through adsorption and subsequent sedimentation (Al-Mur, 2021). Therefore, the pollution status of marine sediments has often been used as an important criterion to evaluate the condition of coastal environments and understand the possible environmental changes caused by anthropogenic activities (Kwok et al, 2014;Beltrame et al, 2009).…”
