- ... Pollution of soils with As, Cd, Co, Cr, Cu, Ni, Pb and Zn, collectively termed heavy metals (HMs), can threaten human health and ecosystem functioning. Therefore, polluted soils must be remediated. Soil washing of strongly polluted soils and phytoextraction on moderately polluted sites seem currently the most attractive remediation methods. Both methods depend on HM solubility (extractability), wh ...

- ... Saponins form a group of plant-produced glycosides with potential as biopesticide ingredients. The environmental fate of saponins has never been fully investigated. In the present study, we use QS-18, a specific saponin from Quillaja saponaria as an example, to quantify hydrolysis under different conditions of pH, temperature and water chemical composition. Saponin hydrolysis in buffer solutions w ...
