XRF analysis of sediments from Nuevitas Bay (Cuba): assessment of current heavy metal contamination
Concentrations of chromium, nickel, copper, zinc and lead in surface sediments from six sta- tions located in Nuevitas Bay (Cuba) were estimated by X-ray fuorescence analysis. The Cr content in sediments shows a strong variation across the studied stations (89-513 mg.kg-1 ), in contrast with the other elements studied. The application of modifed degree of contamina- tion (mCd) classifes as moderate the contamination of Nuevitas Bay. The comparison with Se- diment Quality Guidelines and toxicity mean quotients shows that 100 % of the Sediments are associated with the occasional presence of possible adverse effects to human health.

Summary: | Concentrations of chromium, nickel, copper, zinc and lead in surface sediments from six sta-
tions located in Nuevitas Bay (Cuba) were estimated by X-ray fuorescence analysis. The Cr
content in sediments shows a strong variation across the studied stations (89-513 mg.kg-1
),
in contrast with the other elements studied. The application of modifed degree of contamina-
tion (mCd) classifes as moderate the contamination of Nuevitas Bay. The comparison with Se-
diment Quality Guidelines and toxicity mean quotients shows that 100 % of the Sediments
are associated with the occasional presence of possible adverse effects to human health. |
