| Sumario: | [EN] Environmental degradation or contamination is subject to the presence of heavy metals such as: arsenic, cadmium, mercury, nickel, lead, etc., which may have a geogenic (natural) or anthropogenic origin (produced by hazardous waste), the latter bring with them negative consequences for human health, due to the bioaccumulation of trace elements. Today, spectrometric techniques, through the integration of geospatial technologies and multi-source data, are considered an alternative to traditional field sampling methods, and their use is gaining strength every day. This article uses the so-called “Crosta technique” to detect the presence of characteristic minerals existing in the Southeast Regional Park of the Autonomous Community of Madrid, and, on the other hand, to locate the existence of heavy metals. In a qualitative evaluation, applying the “Crosta composition”, a high concordance between the minerals bentonite and sepiolite is evidenced with the official contrast cartography, from the Geological and Mining Institute of Spain, in addition, a slight modification was made in the input bands of the “Crosta composition”, obtaining an overestimation of the minerals. Finally, by means of a visual interpretation of those main components that contain the spectral information related to heavy metals, a list of coordinates was generated, which will be validated in field campaigns, where the use of spectroradiometers and the chemical analysis of samples will be key to determine the goodness of the results. |
