DIAGNOSIS OF HEAVY METAL POLLUTION IN SURFACE SEDIMENT OF TERMINOS LAGOON, CAMPECHE: A STATISTICAL APPROACH
The levels of heavy metals in sediments of Terminos Lagoon, one of the largest coastal lagoons and of great ecological importance of Mexico, were evaluated; the analysis of heavy metals included geochemical approaches (normalization) and multivariate statistics. Sediment samples were collected at 45...

| description | The levels of heavy metals in sediments of Terminos Lagoon, one of the largest coastal lagoons and of great ecological importance of Mexico, were evaluated; the analysis of heavy metals included geochemical approaches (normalization) and multivariate statistics. Sediment samples were collected at 45 sites in October 2010; digestion was accomplished according to the 3050B method of the Environmental Protection Agency of the United States and quantification was performed by inductively coupled plasma mass spectrometry. Additionally, organic matter content and particle size distribution were determined. The heavy metal concentrations found in this study are relatively low and similar to those reported previously. The spatial distribution of several of the metals analyzed here is probably influenced by the rivers discharge, especially for B, Ba, Co, Mn, Ni and Zn. Significant positive correlations between elements used as normalizers (organic matter content, silt and Fe) indicated that concentrations of most metals analyzed here can be explained by natural biogeochemical processes, except As and Mg. Principal Component Analysis indicated that some of the stations near of the Atasta lagoon mouth, Chumpán River and Palizada River, have higher concentrations ranges in comparison to the local background and therefore are considered vulnerable sites to heavy metal pollution. |

Se evaluaron los niveles de metales pesados en sedimentos de la Laguna de Términos, una de las lagunas costeras más grandes de México y de gran importancia ecológica; para el análisis de metales pesados se emplearon aproximaciones geoquímicas (normalización) y estadística multivariada. Muestras de sedimento fueron recolectadas en 45 sitios en octubre del 2010; la digestión se realizó según el método 3050B de la Agencia de Protección Ambiental de los Estados Unidos y la cuantificación se realizó por espectrometría de plasma inducido. Adicionalmente, se determinó el contenido de materia orgánica y la granulometría. Las concentraciones de metales pesados encontradas en este trabajo son relativamente bajas y similares a las reportadas anteriormente. La distribución espacial de varios de los metales analizados parece estar influenciada por las descargas de ríos, en particular para B, Ba, Co, Mn, Ni y Zn. Las correlaciones positivas significativas entre los elementos usados como normalizadores (contenido de materia orgánica, limo y Fe) indican que las concentraciones de la mayoría de los metales analizados se pueden explicar por procesos biogeoquímicos naturales, con excepción de As y Mg. El análisis de Componentes Principales indicó que algunas de las estaciones cercanas a la boca de la Laguna de Atasta, río Chumpán y río Palizada, presentan concentraciones más allá de los rangos de fondo locales y por lo tanto se consideran sitios vulnerables a la contaminación por metales pesados.Palabras clave: laguna costera, metales pesados, sedimentos.
