“…Otro caso de estudio se llevó a cabo en la ría de Bilbao, una de las zonas más contaminadas de la costa cantábrica debido al vertido directo de efluentes urbanos, mineros e industriales durante los últimos 170 años. Irabien et al (2019) examinaron el registro sedimentario reciente de la bahía interior del Abra (<30 m de profundidad) en la que desemboca el estuario, utilizando un enfoque multidisciplinar que incluyó indicadores geoquímicos (Pb, Zn y Cd), micropaleontológicos (foraminíferos) y radioisotópicos ( 210 Pb, 137 Cs) con el fin de analizar su estado ambiental y destacar las posibles consecuencias de eventos meteorológicos extremos sobre las áreas costeras históricamente industrializadas. En 2015 se recolectaron seis testigos (entre 50 y 69 cm de longitud) utilizando un muestreador hammer corer operado por buzos (Fig.…”

Se presentan las características principales del método de datación de sedimentos recientes mediante el radioisótopo natural 210Pb y su validación utilizando radionucleidos artificiales tales como 137Cs y 239,240Pu. Se hace una revisión de los principios generales de esta metodología, se aportan recomendaciones prácticas para la recogida de testigos sedimentarios en el campo y su posterior procesamiento en el laboratorio, se describen diferentes técnicas analíticas utilizadas en la determinación de sus concentraciones y se explican brevemente varios modelos para la interpretación de los perfiles obtenidos. Por último, se incluyen ejemplos prácticos de su aplicación en secuencias sedimentarias procedentes de distintos ambientes marinos (estuario, bahía y plataforma continental) en el norte de la Península Ibérica.

The impact of urban and agricultural development on sediment quality in the Alvarado Lagoon region in the southern Gulf of Mexico requires an examination of the historical behavior of potential toxic metals (PTMs) and polycyclic aromatic hydrocarbons (PAHs). Consequently, this study aims to assess the ecotoxicological hazards that benthic species and human consumers face in the area. These results are crucial for economic activities in the region and can help prevent future hazards. We examined two sediment profiles from the ecosystem: Profile 1, which spans the period between 1929 and 1998, and Profile 2, which covers the years between 1929 and 2007. The study evaluated the degree of human-induced pollution of six trace metal elements (PTMs): arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb), and vanadium (V) in the sediments of Alvarado Lagoon. The Enrichment Factor (EF) and Geoaccumulation Index (IGeo) were computed as internationally recognized indices to measure the magnitude of contamination and additional anthropogenic and geochemical inputs contributing to the natural levels of the elements. Our analysis indicates that there is no evidence of either enrichment or pollution (EF < 1 class 1; IGeo < 0 class zero) found in the sediments of Alvarado Lagoon. The occurrence of these elements can be attributed to their lithogenic origin, as supported by a significant correlation observed between them. Within the 16 polycyclic aromatic hydrocarbons (PAHs) analyzed, solely Naphthalene (Nap) and Phenanthrene (Phe) were identified in both sediment profiles. The levels of chemicals are indicative of minimal ecotoxicological risks, with Nap ranging between 0.25 and 0.43 µg g−1 and Phe ranging between 0.31 and 0.79 µg g−1. The analysis of factors in this study identified two distinct factors, one related to lithogenic processes and another related to petrogenic processes. The sedimentary profiles of the study site confirmed low levels of potentially toxic metals and polycyclic aromatic hydrocarbons (PAHs), posing insignificant environmental risks. As a result, the ecosystem in this area has demonstrated resilience.
