USO DA ANÁLISE MULTIVARIADA NA AVALIAÇÃO DOS NÍVEIS DE CÁDMIO, CRÔMIO, FERRO, ZINCO, COBRE, CHUMBO E ALUMÍNIO E SUAS INTERCORRELAÇÕES NO COMPARTIMENTO HÍDRICO DA REGIÃO DE BARCARENA-PA
Abstract
The water bodies of the Amazon have suffered
rapid environmental degradation caused by industrial
effluent and other sources. This study aimed to apply the
analysis to check the levels of cadmium, chromium, iron,
zinc, copper, lead and aluminum and their intercorrelations
in the bodies watermark near the town of Barcarena-PA
which is installed an aluminum industrial pole. The metals
analysis was made by ICP-OES. There were no significant
correlations between the elements, just a good negative
correlation between Cu and Fe (-0.627), positive correlation
between Pb and Zn (0.632) and a regular negative
correlation between Cr and Cu (-0.436) and Fe and Pb (--
0.505), positive correlation between Cu and Zn (0.424). The results of PCA show that two groups stood out: Group I Cr- Cd and Al, group II Pb and Zn. These results confirm in part the results obtained by HCA.
