Toxicity assessment of arsenic and cobalt in the presence of aquatic humic substances of different molecular sizes
(Elsevier B.V., 2017-05-01)
using environmentally relevant concentrations of arsenic and cobalt were conducted both in the presence and absence of aquatic humic substances (AHS) and the fractions of different molecular sizes in the range of (< 5, ...
Toxicity assessment of arsenic and cobalt in the presence of aquatic humic substances of different molecular sizes
(2017-05-01)
The release of contaminants in aquatic ecosystems can be influenced by humic acids. In this study, toxicity tests using environmentally relevant concentrations of arsenic and cobalt were conducted both in the presence and ...
Effect of cobalt supplementation and fractionation on the biological response in the biomethanization of olive mill solid waste
(2016)
Due to the low trace metals concentration in the Olive Mill Solid Waste (OMSW), a proposed strategy to improve its biomethanization is the supplementation of key metals to enhance the microorganism activity. Among essential ...
