Giant African land snails (Achatina achatina and Archachatina marginata) as bioindicator of heavy metal pollution

It is important to always monitor the bioaccumulation potential for heavy metals by organisms especially the edible ones, to assess their potential risk to human health. This study evaluated the bioaccumulation of heavy metals in the shell and soft tissues of snails. Forty snails each were purchased from Ikire and Ore towns. The snails’ shells, feet, digestive tracts and glands were analysed for bioaccumulation of...

Investigation of parameters influencing gas production and gasification kinetics of Ziguinchor biomass

This study presents the gasification of three types of biomass residues (wood, stem and shells) under CO2 and water steam, using the different analyses X-ray fluorescence (XRF). Generally, the experiments are carried out using XRF installations and a fixed bed reactor system. The tests are carried out on wood, stems, and shells, because of their energy contents (Lower heating value LHV), and their high availability in...
