This survey evaluated the presence of AFM1 in human urine samples from a specific Brazilian population, as well corn, peanut, and milk consumption measured by two types food inquiry. Urine donors who live city Piracicaba, State São Paulo, Brazil were analyzed to detect aflatoxin M1 (AFM1), an B1 metabolite, which may be used exposure biomarker. The analysis was performed using immunoaffinity clean-up detection high-performance-liquid chromatography with fluorescence detector. A total 69 45...
Introdução: A esquistossomose é uma doença parasitária negligenciada com ampla distribuição no Brasil, especialmente em estados do Nordeste como Alagoas, onde se associa a contextos de pobreza, saneamento inadequado e exclusão social. Objetivo: Analisar o perfil epidemiológico da estado Alagoas entre os anos 2013 2023, considerando incidência casos, mortalidade, taxa cura determinantes sociais envolvidos. Metodologia: Estudo epidemiológico, descritivo, retrospectivo abordagem quantitativa,...
The karstic area of São Domingos, central Brazil, holds extensive drainage systems. In order to understand its biodiversity, various volumes water were filtered with planktonic nets in stretches subterranean and superficial rivers on five different occasions. We sampled four drips (152L), three calcite pools (368L), two fed mainly by percolation (6,395L), coming from a sinkhole (4,175L) along caves, one resurgence (158L), epigean (101,690L). Physical chemical variables measured at some...
Two different approaches to define the ecological status of several catchments in NW Portugal are compared. At a coarser scale, whole stream networks were classified using GIS according variables related to: a) biotic indicators (native and exotic fish species, benthic index characteristics riparian corridor); b) chemical contamination (industrial urban organic loads water quality). This methodology was preceded by typological classification, so that could be determined separately for each...
We examine the Holocene environmental changes in a wet dune slack of Portuguese coast, Poço do Barbarroxa de Baixo. Lithology, organic matter, biological proxies and high-resolution chronology provide estimations sediment accumulation rates conditions relation to sea-level change climate variability during Holocene. Results show that was formed 7.5 cal. ka BP, contemporaneous with last stages rapid rise. This depositional environment under frequent freshwater flooding water ponding allowed...
To assess the effects of urbanization on populations Ocypode quadrata along semiarid Brazilian coast, four urban beaches with varying levels usage and one rural beach as a reference were analyzed. Each was morphologically characterized, considering tidal range (m), slope, length sand grain size (ɸ), Urbanization Index (UI). On each beach, transects marked perpendicular to waterline, 10 meters wide spaced apart, extending from 5 below high tide line base dune (when present) or anthropogenic...

Journal of Coastal Research, SI 50 (Proceedings 9th International Symposium), 231 – 236. Gold Coast, Australia, ISSN 0749.0208 Dune slacks are peculiar features coast with evident scenic, ecological geological value yet existing knowledge on their origin, dynamics is poor.
