| Popis: | The aim of this research was to determine the concentrations of calcium, iron, manganese, zinc, potassium and sodium in the water and leaves of Aechmea blanchetiana (Baker) L.B species collected between the cities of Ilhéus and Itacaré, Bahia, Brazil and verify if the metals found in the water can be absorbed by the leaves. Flame atomic absorption spectrometry (F AAS) and flame photometry were used for the determination of metals. pH measurements, dissolved oxygen and water temperature were also made. The results obtained were used in an exploratory analysis. Principal component analysis (PCA) showed clearly the distinct formation of two clusters and the correlation analysis indicated that the leaves of A. blanchetiana seem to absorb iron, calcium, manganese and zinc from the water tank. |
