Simultaneous and direct determination of glyphosate and AMPA in water samples from the hydroponic cultivation of eucalyptus seedlings using HPLC-ICP-MS/MS
Autor: Lázaro C. Sicupira, Flaviano O. Silvério, Rodrigo Eduardo Barros, João P. F. Tiago, Gevany Paulino de Pinho
Publikováno v: Journal of environmental science and health. Part. B, Pesticides, food contaminants, and agricultural wastes. 55(6)
Glyphosate is the main herbicide currently used in the world due to wide applicability and efficiency in controlling weeds in many crops. However, its overuse may lead to undesirable impacts on the environment and to human health in the long run. Thi
