“…The effectiveness of micro-Raman in the investigation of weathering products is also evident in a study of soils present at an abandoned zinc and lead mine by Goienaga et al (2011). By analyzing samples from the top 2 cm of soil, they were able to identify the presence of 16 primary (including dolomite, calcite, fluorite, graphite, and rutile) and 23 secondary minerals (zinc, cadmium, and lead minerals) resulting from several processes including: dissolution-precipitation processes; weathering of superficial mineral phases; percolation of dissolved ions; and precipitation.…”

“…The work was centered in two kinds of samples collected in an abandoned blendegalena mine described elsewhere. 44 The most likely source of the dust-type PM that is more relevant in the studied area is the nonvegetated soils. Thus, with consideration that the closer to the polluting activity the higher the metal content in soil, 20 topsoil (first 5 cm) samples were collected at nonvegetated areas near the mine entrance and the surrounding tailings.…”

“…also showed a wide distribution. The reasons for selecting these elements were (i) copper is a metal whose presence is relevant and can cause damage to human health when inhaled (Figure 3b), (ii) lead is a metal present in the galena that was extracted from the mine when it was exploited 44 (Figure 3c), and (iii) the presence of sulfur is indicative of both the degree of erosion of the extracted minerals (blende and galena) and the acid mine drainage that is taking place in the area (Figure 3d). From analysis of the information provided by the elemental maps obtained with SEM-EDX, some additional information can also be derived.…”

Clean air is considered to be a basic requirement of human health and well-being. An increasing range of adverse health effects has been linked to air pollution, at ever-lower concentrations. This research shows the newly developed Structural and Chemical Analyzer (SCA) to be a successful combination of Raman spectroscopy and scanning electron microscope-energy dispersive X-rays that opens up new insight into the composition of particulate matter (PM). The results obtained with soil and lichen samples demonstrate the capability of the technique to obtain elemental and molecular information of every single atmospheric PM focused at the micrometer and submicrometer levels. The SCA approach permitted the individual PM analysis, allowing the identification of the molecular (most commonly as sulphides, sulphates, carbonates, or oxides) form in which several hazardous metals (Zn, Pb, Cu, etc.) are evolved into potentially inhalable PM. During the present research, the synchronization of both techniques at a time revealed the morphological, elemental, and molecular forms of metal-rich PM, avoiding some analysis precautions and making the sample preparation and measurement steps more dynamic. In addition, the thermodynamic simulations carried out with the information obtained were helpful to differentiate whether the PM may be retained in the alveoli (i.e., galena) or if it may be dissolved and pass into the bloodstream (i.e., plattnerite).

“…Metals can be more or less mobile in the soil, in relation to their geochemical form which affects their solubility and thus their bioavailability . Therefore, metal speciation by molecular spectroscopy techniques is important in order to evaluate metal mobility and potential bioavailability of hazardous compounds . The use of Raman spectroscopy provides structural and molecular information about the compounds originated by corrosion of the galvanised steel and gives an idea of the potential risk of the pollutants in soil.…”

Urban soils are potential reservoirs of toxic metals as a consequence of traffic emissions. Sources like brake linings, tyres, road pavement, exhaust fumes, guardrail, traffic signals and other galvanised steel structures are used in a large variety of external constructions in the modern urban areas. Their beneficial properties from a corrosion and oxidation perspective are well-known but less is known about their contribution to the environmental fate of corrosion-induced released zinc. In this work, the impact of guardrails and other traffic pollutants on urban soils has been studied by means of Raman spectroscopy (molecular speciation) and thermodynamic speciation to understand the mechanisms of metal release and uptake by the soils. Hydrozincite, Zn 5 (CO 3 ) 2 (OH) 6 , was identified by means of Raman spectroscopy as the degradation compound of the galvanised zinc layer from guardrails which leads to the formation of soluble zinc, by acidic attack of the urban atmosphere, that drops and accumulate (zinc nitrate was identified) in soils. This fact shows the environmental risk of zinc release from the guardrails because zinc nitrate can be easily mobilised by water runoff, affecting the surrounding areas or groundwater. Other traffic pollutant that reaches guardrail and soil by atmospheric deposition, such as barium, was also identified in soil as well as in the guardrail in its carbonate form, BaCO 3 . Because of its low solubility, barium will accumulate in urban soils.
