摘要: Abstract Two species of aquatic macrophytes were collected at two places the Tagus river, Rodao and Valada, during winter season. They completely immersed covered with a thick layer sediment. The aim research was to gauge degree pollution from concentrations minor- trace-elements. For most elements, sediments contain higher than plants. Different washing procedures tested optimize sediment removal. various samples so obtained analysed by PIXE INAA. results showed that plant material could never be free A correction factor calculated for each element on basis decreasing concentration Ti in course successive procedures. values elemental composition these plants should considered as valid approximations true contents
