Palabras clave: elementos traza, sedimentos estuarinos, índices de contaminación, agricultura, acuicultura RESUMEN La calidad de los sedimentos superficiales de las lagunas costeras Lobos y Tóbari, ambas receptoras de efluentes del Valle del Yaqui, en el Golfo de California, México, fue evaluada. Las concentraciones de níquel, zinc, cobre, cadmio, manganeso, plomo y hierro fueron determinadas en sedimentos de estas lagunas y del estero el Soldado que es un área natural protegida sin descargas antrópicas. El índice de contaminación metálica (ICM), el factor de enriquecimiento (FE) y el índice de geoacumulación (I geo ) fueron calculados. Se utilizaron los valores guía de calidad de sedimento (SQV, por sus siglas en inglés) para valorar el potencial riesgo a la salud de la biota. La laguna Lobos presentó la media de concentración más alta de zinc (70.1 µg/g) y cobre (16.3 µg/g), Tóbari la más alta de manganeso (747 µg/g) y El Soldado la más baja de hierro (1.05 %), así como también el menor ICM. Tanto en la laguna Lobos como en la Tóbari, el manganeso fue el único elemento que presentó un FE que indica influencia antropogénica y un I geo que corresponde a moderado. Los sitios más afectados en ambas lagunas fueron los más cercanos a las zonas agrícolas. Los SQV sugieren que en los sitios con concentraciones de níquel > 51.6μg/g (registrado en un sitio en Lobos) y de manganeso > 260μg/g (Lobos y Tóbari), deben establecerse medidas de mitigación. Lo anterior, dado que a esos niveles, dichos elementos pueden causar efectos adversos y deterioro del habitat que las especies utilizan para su reproducción, crianza y/o protección en estos ecosistemas costeros.

“…The Ziya River system (ZYS), which is a major water system in the Haihe Basin, has been significantly contaminated by heavy metals due to industrial development and rapid urbanization. Previous studies have already reported high metal contents in the sediments from the ZYS (Tang et al 2015, Tang et al 2014, Tang et al 2013. The sediments of the ZYS have been considered to be high ecological risk due to heavy metals.…”

The distributions and mobilities of metals in pore water strongly influence the biogeochemical processes and bioavailabilities of metals at sediment-water interfaces. Heavy metal concentrations were measured in pore water samples from the Shaocun River (SR), the Wangyang River (WR), and the Xiao River (XR), tributaries of the Ziya River system, northern China. The aim was to assess heavy metal contamination in the system and the associated environmental risks. The mean Cd, Cr, Cu, Ni, Pb, and Zn concentrations in all three tributaries were 0.373, 57.1, 37.7, 20.4, 14.0, and 90.6 μg/L, respectively. The calculated Cd, Cr, Cu, Ni, Pb, and Zn diffusion fluxes in the rivers were −0.427 to 0.469, −71.8 to 42.5, 3.16 to 86.6, 5.29 to 14.0, 7.24 to 19.0, and −204 to 21.9 μg/(m 2 day), respectively, showing that the pore water was a source of most of the metals to the water column. Only Cu and Pb in the XR and Cu in the WR exceeded the final chronic value recommended by the US Environmental Protection Agency, but the metals in the WR sediment could have caused toxic effects.These results are likely to be useful to the authorities responsible for sustainable river management.

“…In 1980, Lars Hakanson reported an ecological risk index for aquatic pollution control; therefore, Hakanson' method has been often used in ecological risk assessment as a diagnostic tool to penetrate one of many possible avenues towards a potential ecological risk index, i.e., to sort out which drainage area, reservoir, and substances should be given special attention 7,10,21,22 (Tables 4). The index is calculated as the following equations (4), (5), (6), (7), (8): …”

Abstract. The aim of this paper is to assess the heavy metal pollution and potential ecological risk in surface sediments from accumulation lakes on the sector inferior of the Olt River: Govora, Babeni-Marcea, Zavideni, Dragasani and Strejesti. Heavy metals are among the most persistent of pollutants in the ecosystem such as water, sediments and biota because of their resistance to decomposition in natural condition. Accumulation of heavy metals in the environment results primarily from human activity. In addition, an important role in the "enrichment" heavy metal reservoirs they have natural processes, such as the disintegration of rocks and volcanic activities. Sediment is the ultimate destination for heavy metals discharged into the environment. The main aspects of the present work are to: determine to content and spatial distribution of heavy metals (Cd, Cu, Ni, Zn, Pb, Cr, Hg) in surface sediments from accumulation lakes on the sector inferior of the Olt River; calculating the pollution load index (PLI), the Nemerow pollution index (PI) and potential ecological risk (RI) in order to evaluate the potential ecological risk.Keywords: heavy metals, surface sediment, accumulation lakes, potential ecological risk AIMS AND BACKGROUNDHeavy metals are among the most persistent of pollutants in the ecosystem such as water, sediments and biota because of their resistance to decomposition in natural condition. Metal have low solubility in water, get adsorbed and accumulated on bottom sediments 1 . The increase the heavy metal content in the reservoirs is shown notably by increasing their concentration in bottom sediments. Accumulation of heavy metals in the environment results primarily from human activity. In addition, an
