Abstract: La presente obra es resultado de una serie de diversos esfuerzos para integrar un catálogo de los frecuentes huracanes y otros fenómenos hidrometeorológicos que han acontecido en México durante cinco siglos, contemplando desde la época prehispánica hasta el siglo XX. Los coordinadores de los textos del libro, integraron un amplio grupo de investigación, con múltiples resultados que son reportados en la parte medular del estudio. Esta publicación, además, está asociada a una base de datos, consultable en Intern… Show more

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.

Objetivo: analizar la erupción del volcán Cosigüina en 1835 relacionando la historia del clima y el estudio de las emociones en el marco interdisciplinario de la historia ambiental, un ángulo pertinente para entrelazar las vivencias individuales y colectivas con el paisaje. Metodología: a la luz de perspectivas historiográficas recientes, se examinan cinco testimonios sobre la erupción y se otorgan elementos para ampliar el entendimiento histórico de las manifestaciones extremas de la naturaleza y las respuestas de las sociedades. Al mismo tiempo, se contextualiza el evento vulcanológico ocurrido en el estado de Nicaragua en el marco de la Pequeña Edad de Hielo y se presenta el entramado social del golfo de Fonseca donde se generaron los relatos. Originalidad: aunque el estallido del Cosigüina ha sido examinado por la vulcanología recurriendo a testimonios, el recuento de los acontecimientos no se ha problematizado desde la investigación histórica, a la que sumamos con este artículo que además incorpora un testimonio inédito. Conclusiones: estableciendo un diálogo entre las historias del clima y de las emociones, centrarse en el miedo y el asombro ante los fenómenos de la naturaleza permite una revaloración creativa en la historia ambiental.
