abstract

• Heavy metal accumulation in marine ecosystems at Guanahacabibes peninsula south coast (Cuba) is an increasing environmental concern due to increasing tourism in the last 10 to 15 years. In this way, some species such as Syringodium filiforme, Thalassia testudinum, and Sargassum buxifolium would exhibit heavy metals bio-indicating accumulation characteristics. Characterization of such bio-indicating species was carried out in this research followed by lead adsorption capacity determination for each one. The analysis included Scanning Electron Microscopy with Dispersive Energy of X-rays, Infrared Spectroscopy by Fourier Transform, BET Analysis and Optical Spectrometry of Emission with Inductively Coupled Plasma, etc. Results showed a very significant heavy metals bioaccumulation potential of tested species based on the physicochemical characteristics found in the biomass. The lead adsorption capacities were between 120 and 150 mg/g for Syringodium filiforme, Thalassia testudinum, and Sargassum buxifolium, respectively, and were greater than those reported for materials of similar origin and composition.
