Compositional signature of trace elements in stream sediments along the Babahoy...
Cabrera, Marlon; Pazo, Maria; Gerassis Davite, Saki; Albuquerque, Maria Teresa; Sierra, C.; Boente, CarlosThe high concentration of potencially toxic elements (PTEs) in stream sediments may pose a significant threat since the pollutants may travel long distances to the sea, affecting aquatic environments and public health. When rivers cross large cities, minning, or cultivated areas, it is usually observing an increasing concentration of PTEs downstream, reachiong hazardeous levels due to the ability and persistenc...
Combining raw and compositional data to determine the spatial patterns of poten...
Boente, Carlos; Albuquerque, M.T.D.; Fernández-Braña, A.; Gerassis, Saki; Sierra, C.; Gallego, J.R.When considering complex scenarios involving several attributes, such as in environmental characterization, a clearer picture of reality can be achieved through the dimensional reduction of data. In this context, maps facilitate the visualization of spatial patterns of contaminant distribution and the identification of enriched areas. A set, of 15 Potentially Toxic Elements (PTEs) – (As, Ba, Cd, Co, Cr, Cu, Hg,...
Developing a new Bayesian Risk Index for risk evaluation of soil contamination
Albuquerque, M. T. D.; Gerassis, S.; Sierra, C.; Taboada, J.; Martín, J. E.; Antunes, Isabel Margarida Horta Ribeiro; Gallego, J. R.Industrial and agricultural activities heavily constrain soil quality. Potentially Toxic Elements (PTEs) are a threat to public health and the environment alike. In this regard, the identification of areas that require remediation is crucial. In the herein research a geochemical dataset (230 samples) comprising 14 elements (Cu, Pb, Zn, Ag, Ni, Mn, Fe, As, Cd, V, Cr, Ti, Al and S) was gathered throughout eight d...
