Estimation of Mg, Cd, and Ni levels in urban waterfront using one-dimensional transport model

Accurate quantification of heavy metals is essential for optimizing remedial efforts at polluted waterfronts. Although surface water quality models can be helpful tools for rapid quantification of heavy metals in streams, they cannot be extrapolated to other water bodies. This study estimated Mg, Cd, and Ni levels in one of the polluted urban waterfronts in the Niger Delta Province, Nigeria (5.317°N, 6.467°E)...

Dynamics of microbial communities in co-digestion of water hyacinth (Eichhornia crassipes) with ruminal slaughterhouse waste under mesophilic conditions

Co-digestion of water hyacinth (WH) (E. crassipes) with ruminal slaughterhouse waste (RSW) has the potential for improving biogas production by complementing process parameters. This study evaluated microbial communities in co-digestion of WH with RSW at 32ËšC by isolation, phenotype analysis, DNA extraction and PCR amplification of the 16S rRNA genes. Digestion of WH and RSW separately exhibited lag times of 5 to 20...
