Determination of Cu, Zn, Pb and Cd by Atomic Emission Spectrometry with Inductively Coupled Plasma in Waters and Sediments from San Juan Ecosystem, Santiago de Cuba

Abstract

In this paper the levels of concentration of copper, zinc, lead and cadmium in waters and sediments from the ecosystem San Juan in the Santiago of Cuba province were evaluated. Two sampling of the ecosystem in two stations belonging to the high and middle part of the river, in rainy
and little rainy periods were carried out. The conservation and treatment of the samples were developed according to established standards and the determinations of the elements were realized using atomic emission spectrometry with inductively coupled plasma. The concentrations intervals
of the studied elements were established so much in the superficial waters like in the sediments and it was demonstrated that exists statistical significant differences for the factors station, period and type of sample, being the middle part of the river, the little rainy period and the sediments, where the grater concentrations of the pollutants appear.
