Chemical data on environmental matrices from an abandoned mining site

Abstract

This article contains analytical data on chemical composition of waters and solid samples (mining wastes and biominerals) collected in an abandoned mining area, and they are related with the research article “Geochemistry of rare earth elements in water and solid materials at abandoned mines in SW Sardinia (Italy)” (Medas et al., 2013). Specifically, we present physicochemical data (temperature, electrical conductivity, pH, and redox potential), major components and the main contaminants (Zn, Mn, Cd, Ni, Cu, Pb) detected in stream waters and drainages from mine wastes. Waters were monitored from 2009 to 2011 during different seasonal conditions to give an insight into metal dispersion under different hydrological conditions.

XRD-Thermal Combined Analyses: An Approach to Evaluate the Potential of Phytoremediation, Phytomining, and Biochar Production

“…The samples of Juncus acutus were harvested along the banks of two streams that flow within the above described mine district (Figure 1). The seasonal behavior of the two selected streams—Rio Irvi, Casargiu [45,46] and Rio Naracauli [47], Ingurtosu—is due to the climate of southern Sardinia, characterized by a long dry season starting in May and ending in September or October with minimum rainfalls in July and maximum in November [48]. Sampling was performed at the end of the dry period and thus with low levels in the streams.…”
