DIAZ RIZO, Oscar et al. XRF analysis of sediments from Nuevitas Bay (Cuba): assessment of current heavy metal contamination. Nucleus [online]. 2014, n.55, pp. 11-14. ISSN 0864-084X.

Concentrations of chromium, nickel, copper, zinc and lead in surface sediments from six stations located in Nuevitas Bay (Cuba) were estimated by X-ray fluorescence analysis. The Cr content in sediments shows a strong variation across the studied stations (89-513 ), in contrast with the other elements studied. The application of modified degree of contamination () classifies as moderate the contamination of Nuevitas Bay. The comparison with Sediment Quality Guidelines (SQGs) and toxicity mean quotients shows that 100 % of the sediments are associated with the occasional presence of possible adverse effects to human health
