Abstract

Society has progressively appropriated nature since ancient times. With the advent of modernization or globalization, technological and social development, supported by the capitalist system of production, has brought about even more intense transformations on planet Earth. These modifications are present in the Anthropocene, a geological Epoch in which humanity plays a predominant role, becoming a geological-geomorphological-pedological agent capable of irreversibly altering the dynamics of the terrain. In this scenario, where capitalist paradigms reverberate in both urban and rural areas, soils are targets of degradation and contamination by human action, transforming into Anthroposols through anthropedogenesis: pedological volumes with characteristics very distinct from natural ones. This recent classification proposal, although not yet official, systematizes knowledge about these materials and contributes to the discussion about soils in the Anthropocene. Thus, the aim of this work is to contribute to the document "Antropossolos: proposta de ordem (1ª aproximação)", elaborated by Curcio, Lima, and Giarola (2004), suggesting a classificatory suborder of Anthroposoils that reflects the uniqueness of agricultural volumes contaminated by potentially toxic metals (PTMs) (As, Cd, Cu, Cr, and Pb) present in pesticides, using samples from sweet potato (Ipomoea batatas) cultivation areas under conventional preparation in the Timburi APA, located in the municipality of Presidente Prudente /SP. To do so, land use maps will be made, soil samples will be collected for routine physical and chemical analyses, and morphological descriptions will be provided to analyze the possible existence of Anthroposoils and their classification into a new suborder. The identification of PTMs will be carried out through Raman spectroscopy and Differential Pulse Anodic Stripping Voltammetry (ASV). This work ultimately aims to confirm the existence of Anthroposols in the Anthropocene, in order to contribute to the debate related to Brazilian "anthropopedology."
