WebFeb 27, 2024 · In this study, we assessed the acute and chronic toxic effects of Sb (III) and Sb (V) on Eisenia fetida (Savingy) (E. fetida) by applying the filter paper contact method, aged soil treatment, and avoidance test experiment. In the acute filter paper contact test, the LC50 values for Sb (III) were 2581 mg/L (24 h), 1427 mg/L (48 h), and 666 mg/L (72 h), … WebApr 20, 2006 · The S2 state properties of Sb-tetraphenylporphyrin (SbTPP) derivatives were investigated using subpicosecond spectroscopic methods. The S2 fluorescence of various SbTPP derivatives was observed for the first time. It was revealed that the S2 fluorescence lifetime changed depending on the donor-ability of the ligand because of the contribution …
