The Importance Of Seaweed As Bioremediation Natural Agent

Abstract

Seaweed has emerged as a promising bioremediation agent for addressing heavy metal contamination in aquatic environments. This study presents a comprehensive review of ten selected references to explore the potential of seaweed-based bioremediation and its implications for environmental sustainability. The findings highlight the significant capacity of seaweed species to accumulate heavy metals, emphasizing the importance of species selection based on their metal uptake capabilities. Seaweed biomass and biochar demonstrate remarkable adsorption properties, providing efficient means of removing heavy metals from contaminated water through physical adsorption and ion exchange processes. Seaweed-based bioremediation techniques offer several advantages over traditional methods. The studies underscore the importance of considering environmental conditions and the presence of coexisting pollutants in designing seaweed-based bioremediation strategies. Optimal light availability, temperature, nutrient levels, and water quality parameters are critical for maximizing seaweed's metal removal efficiency. Overall, seaweed-based bioremediation offers a promising and sustainable approach for addressing heavy metal pollution in aquatic environments. Future research should focus on overcoming challenges related to biomass management, ecological impacts, and scaling up cultivation and processing methods to ensure the widespread implementation of this eco-friendly solution.
