| 英文摘要 | Agricultural application of large amounts of glyphosate [n-(phosphonomethyl)-glycine] may affect soil metal behaviors to some extend, because glyphosate can react with many kinds of metals to form metal complexes. cosorption of zn and glyphosate on a red soil (rs, udic ferrosols) and a wushan soil (ws, anthrosol) was studied. in comparison with the ws, the rs has less adsorption capacity for zn and higher for glyphosate. the presence of glyphosate decreased zn adsorption on the two soils, which are resulted from the decreased equilibrium solution ph caused by the added glyphosate, and also the formation of water-soluble complexes of glyphosate with solution zn2+ that had lower affinity to soil surface in comparison with zn2+ itself. such effect is more significant on the rs than on the ws, mainly because of the less adsorption quantity of zn on the former one. on the contrary, the presence of zn increased the adsorption quantities of glyphosate on the rs and ws, which is resulted from the decreasing ph value of the equilibrium solution caused by zn2+ exchange with h+ ions of soil surface. such results suggest that glyphosate in field may increase the mobility and bioavailability of zn and correspondingly increase its environmental risk.
