“…19,43 These adsorbed metals (linked to Fe-Mn oxides) have the potential to be transferred to the aquatic environment, by means of changes in the redox potential or pH of the medium. 11,13,44,45 In the oxidizable fraction (F3), relatively high values are observed for Cr and Cu. On average, 29.5% of Cr and 25.0% of Cu were found in this fraction, ranging from 11.7-60.1% for Cr and 8.2-42.6% for Cu among the sampling points (S1 to S13).…”

“…The large quantity of these elements in this fraction shows that they are linked to the crystalline network of the secondary minerals and are not easily remobilized to the aquatic environment. 13,19,28,[45][46][47] Figure 3 also shows that there was a modification in the fractionation profile of trace elements (S11 to S13) after the Mariana environmental accident with deposition of the mud layer (S11a to S13a). Modification in the fractionation profile can be better observed in Table 3, where the average values between sampling points are presented for the concentration of each element in the different sediment fractions.…”

“…The metals (Cu and Cr) are strongly complexed by organic matter (humic substances) in the sediments, being released after degradation of organic matter or oxidation of sulphides to sulphates. 17,19,45 Furthermore, Cu is commonly found to be strongly bound to organic matter, due to the high stability constant of organic copper compounds. 28 The largest quantities of As found in the oxidizable fraction (F3) of the sediments at sampling sites S6 and S7 (Figure 3) may be related to contribution of the oxidative dissolution of arsenic-rich sulfide minerals from the Passagem Mine (municipality of Mariana ), the oldest and most important gold mine in the region located upstream of S6 and S7.…”

, the Fundão dam ruptured which caused the spill of a large quantity of tailings from the extraction of iron ores to the Gualaxo do Norte, Carmo and Doce Rivers. Seven months prior to the rupture, our group had collected water and sediment samples at 13 points along the Tripuí Creek and the entire length of the Carmo River. Six months after deposition of the mud, new samples were collected in the Carmo River. Thus, the present study sought to evaluate the concentrations of trace elements in the waters and their distribution and mobility in sediment by BCR sequential extraction before and after the deposition of the tailings mud. Arsenic concentrations in the water samples were between 10.4 and 50.4 µg L -1 , which exceeded 10 ug L -1 (maximum limit permitted by Brazilian environmental regulations for water destined for human consumption) . The tailing mud layer on the sediments caused concentration increases of As (20%), Cd (13%), Co (5%), Cr (9%), Cu (11%), Ni (4%), Pb (7%) and Zn (19%) in the easily remobilized fractions. The presence of the elements in these fractions was indicative of high ecotoxicological risk and potential harm to the health of the local population.

“…While those samples collected within 20 m of the highway may contained pollution from direct vehicle traffic, it is not seen as a major contributor to the overall data set. According to Botsou et al [30] and others for instance, detections of metals near roads and highways are not an issue of concern as vehicle emissions rarely excessed 10 m from the road traffic [31,32].…”

Abstract:Hazardous substances (e.g., toxic elements, oxides of nitrogen, carbon and sulfur) are discharged to the environment by a number of natural and anthropogenic activities. Anthropogenic air pollution commonly contains trace elements derived from contaminants and additives released into the atmosphere during fossil fuel combustion (automobiles, power generation, etc.) as well as physical processes (e.g., metal refining, vehicle brake wear, and tire and pavement wear). Analysis of pollutant chemical concentrations in lichens collected across the Las Vegas Valley allows documentation of the distribution of air pollution in the Valley. Analyses of lichen biomass (Buellia dispersa), when compared to windrose diagrams, shows pathways of airborne pollutant transport across the Las Vegas Valley. The west and north sectors of the Las Vegas Valley contained the lowest target contaminates (e.g., Cr, Cu, Co, Pb, Ni) and the highest NO 3 − while the east and south sectors contained the highest levels of target contaminates and lowest NO 3 − . Additionally, metals and NO 3 − detected in the east and south sectors of the valley indicate that air pollution generated in the valley is moving from the south to the north-northeast and across the valley, exiting on the north and south side of Frenchman Mountain.

“…En este sentido, los procedimientos de extracción secuencial X CONGRESO IBÉRICO DE AGROINGENIERÍA X CONGRESSO IBÉRICO DE AGROENGENHARIA 3 -6 septiembre 2019, Huesca -España proporcionan información tanto sobre la identificación de los principales lugares de unión, como la fuerza de la unión entre el metal y los distintos constituyentes del suelo. Los metales unidos a las fases lábiles del suelo (es decir, intercambiables o unidos a carbonatos) son más propensos a ser absorbidos por las plantas y transferidos a la cadena trófica que aquellos unidos principalmente a la matriz mineral del suelo [10]. A pesar de la gran cantidad de información existente sobre la concentración de metales en los suelos, las investigaciones sobre la influencia del sistema de cultivo en la acumulación y especiación de metales en los suelos agrícolas siguen siendo limitadas.…”

Concentración, distribución y procedencia de metales y metaloides en suelos bajo diferentes sistemas de cultivo Resumen: El objetivo de este estudio fue evaluar la influencia de cuatro tipos de cultivo en la acumulación y especiación de metales en suelos, e identificar su procedencia. Se tomaron 40 muestras de suelo de cereales, frutales, cítricos y hortícolas, y se analizaron Cd, Co, Cr, Cu, Cu, Fe, Mn, Ni, Pb, Zn, As y su especiación química. Los resultados mostraron que los suelos de cítricos y hortícolas estaban enriquecidos con Pb y Cd, los de cereales con Pb y los de frutales con Zn, destacando que todos estaban enriquecidos con Cu, especialmente los suelos de cítricos. Los suelos de cereales tienen un mayor riesgo debido a la alta movilidad de Cd, mientras que en los de hortícolas el mayor riesgo fue causado por la movilidad de Pb. En los suelos de cereales, Pb, Cu y Cd tenían origen antrópico, mientras que el resto tenía un origen geológico. En cítricos, Cd, Pb, Zn y Cu tenían un origen antropogénico, y el resto geogénico. En cítricos, As, Pb, Zn, Cu, Mn y Cd tenían un origen antropogénico mientras que Fe y Cr tenían un origen geogénico. Los suelos hortícolas, Cu, Mn, Pb, and Zn tendrían un origen antropogénico mientras que el resto tendrían un origen geogénico. Por lo tanto, se puede concluir que la producción agrícola intensiva enriquece los suelos por metales de acuerdo con el tipo de cultivo.Palabras clave: especiación química, metales pesados, análisis multivariante, sistema de cultivo
