“…Higher values were obtained in the Kaohsiung harbours in Taiwan, with similar characteristics to those of the Tangier Bay, where over 70% of domestic wastewaters were still directly being discharged untreated into the rivers and several industrial parks considered as contaminated zones were located around the city of Kaohsiung (Chen et al, 2007). Others works related to contamination of sediments in Spanish harbours have reported higher values of Cu, Pb, Cd and Zn than in the Tangier Bay in Ceuta (Guerra-Garcia and García-Gómez, 2005), Cartagena and Cádiz (Casado-Martínez et al, 2006). The Cr and Ni levels in the Tangier Bay were generally lower than those reported in the Cartagena and Cádiz harbours.…”

“…This fact could indicate a common origin of metals, which are probably transported by the organic matter from the sewage effluents of urban influence, as reported by Rodríguez-Barroso et al (2009) in sediments of the River Mghogha, probably due to a common contamination source coming from an industrial park. Table 4 shows the average metal concentrations reported in sediments from different parts of northern Morocco and other harbours and bays in the world (Achab et al, 2007;Bellucci et al, 2003;Chen et al, 2007;GuerraGarcía and García-Gómez, 2005;Casado-Martínez et al, 2006). Sediments coming from northern Morocco (a salt marsh core from Nador) showed low metal concentrations and the authors suggested that they are probably very close to the natural background (Bellucci et al, 2003).…”

SUMMARY: The distribution, enrichment, and accumulation of heavy metals in the surface sediments of the Tangier Bay, Morocco, were investigated. Surface sediment samples from eleven locations in the Bay of Tangier were collected in 2007 and characterized for grain size, organic matter and metal content (e.g. Fe, Mn, Cr, Cu, Ni, Pb, Zn and Cd). The evaluation of the heavy metal contamination status of the bay showed minor enrichment by the enrichment factors (EF) calculation, corroborated by the metal pollution index (MPI). The results of a Pearson correlation showed high positive correlations among organic carbon and most metals (0.788

“…6,21 Datos sobre la movilidad y biodisponibilidad potencial de los elementos obtenidos con estos procedimientos secuenciales resultan muy útiles en la estimación de riesgos ecológicos. 22,23 Por otra parte, la determinación cuantitativa del grado de contaminación de un sedimento puede realizarse mediante el empleo de los llamados índices de contaminación. 24 Existen diversos criterios basados en los coeficientes de enriquecimiento o factores de concentración, que permiten establecer el índice de contaminación en sedimentos.…”

Recebido em 28/8/11; aceito em 1/12/11; publicado na web em 28/2/12 STUDY OF METAL CONTAMINATION IN AQUATIC SEDIMENTS OF THE BAY OF MATANZAS. Surface sediments of the Bay of Matanzas (Cuba) were studied to assess its environmental quality by using several criteria (metal content index, pollution load index and sediment quality guidelines). Two partial digestion sediment procedures and a modified BCR sequential extraction were used. The concentrations of metals were measured by atomic spectroscopy methods. The founded contents of Cu (2,4-27,9 mg kg -1 ), Zn (2,5-55,5 mg kg -1 ) and Ni (8,,2 mg kg -1 ) were below those reported by other authors. The results obtained suggested that the most polluted sites were 3, 5, and 6. The sequential extraction procedure showed that most of the studied metals were associated to the more stable fractions.Keywords: metal pollution; marine sediments; digestion and extraction methods. INTRODUCCIÓNCuba, debido a sus características geográficas particulares, posee amplias y diversas zonas costeras, cuya calidad ambiental, generalmente, se ve comprometida por los diferentes usos socio-económicos a que son destinadas. La Bahía de Matanzas es un ejemplo de ello. En investigaciones desarrolladas en esta zona se han evaluado alteraciones del contenido total en sedimentos de diversos metales pesados, tales como, Cu, Ni y Zn, entre otros, estableciéndose igualmente su posible origen. 1-3 Sin embargo, no se conoce la fracción disponible de metales para los organismos vivos en el ecosistema. Además, no se ha evaluado la presencia de V, elemento de particular interés debido a la actividad que se desarrolla en esta bahía relacionada con la industria del petróleo cubana.Es conocido que la contaminación por metales en sedimentos no puede ser evaluada sólo a partir de su contenido total, ya que la distribución de diversas formas químicas del metal en diferentes fases del sedimento, puede condicionar su mayor o menor movilidad, y por tanto la magnitud de su impacto sobre el ecosistema. 4-6 Para evaluar de forma selectiva diferentes fracciones metálicas, diversos métodos de lixiviación parcial ácida de los metales, también llamados métodos de una sola etapa o métodos simples, han sido empleados en lugar de los métodos de extracción total. 7-11 Varios de estos métodos constituyen normas internacionales (DIN 38414, EPA 3050 y 3051, ASTM D 3974 e ISO 11466, entre otros). En general, existe poca información sobre la relación entre las fases geoquímicas del sedimento disueltas y la eficiencia de extracción que se alcanza para cada elemento por un método específico. 12,13 La información que se obtiene sobre el contenido del metal varía en dependencia de la composición del sedimento, del elemento de interés y de la fortaleza del ataque que se realiza, 12,14-16 por lo que resulta conveniente determinar la eficiencia de extracción de los metales de interés en los sedimentos en estudio, junto al contenido total, para una mejor interpretación ambiental de los resultados. 17 Otros métodos frecuentemente emplead...

“…The powder samples, less than 63 μm, are used for heavy metal analysis. Total metal concentration can be measured by acid digestion in an airtight Teflon system [29]; digestion by aqua regia and concentrated HF using microwave heating and metal concentration measurement by AAS equipped with a THGA graphite furnace, Mercury Hydride System and a flame system [30]; microwave acid digestion (HNO 3 and aqua regia) and determination by flame or furnace AAS [31]; digestion with HNO 3 , HF, aqua regia and HClO 4 and determination by AAS [32]; a three-step treatment of sample drying, acid digestion (by HF-HClO 4 -HNO 3 mixture in Teflon beakers) and AAS analysis [33]; acid digestion (HNO 3, HClO 4 and HF in Teflon cups) followed by heating, cooling and determination by AAS [34]; digestion with a mixture of hydrofluoric and perchloric acids in a platinum crucible, evaporation, dissolution and determination by flame AAS [35].…”
