    Description: 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.
    Description: Se determinan, mediante el análisis por fuorescencia de rayos X, las concentraciones de cromo, níquel, cobre, zinc y plomo en sedimentos superfciales de seis estaciones de la Bahía de Nuevitas en Cuba. El contenido de cromo se determinó con un intervalo de gran variación (89-513 mg.kg-1 ) en las estaciones estudiadas. La aplicación del grado de contaminación modifcado (mCd) clasifcó la contaminación de los sedimentos de la Bahía de Nuevitas como de “grado moderado”. La comparación con las Guías de Calidad de Sedimentos y del cociente promedio de toxicidad, mostró que el 100 % de los sedimentos estudiados están asociados a la presencia ocasional de posibles efectos adversos a la salud humana.
