Contamination by bisphenol A (BPA) and microplastics in aquatic and terrestrial environments has intensified in recent decades, emerging as a significant environmental and public health issue. In this study, five soil sampling sites were investigated, with samples collected from a depth of 10–20 cm in the municipality of Francisco Beltrão, Paraná, selected based on the degree of anthropogenic influence. The particle size distribution indicated a sandy texture (P1: 22.5% sand) and predominantly clayey texture (P3: 81% clay; P5: 79%). The organic matter content ranged from 0.402% (P4) to 3.753% (P2), while the pH ranged from acidic to slightly acidic (4.8–5.8) and the cation exchange capacity (CEC) varied between 8.72 and 67.69 cmol·kg⁻¹. FTIR spectroscopy identified bands associated with clay minerals, organic matter, and silicates, notably a band at 1100 cm⁻¹ (P3), indicative of synthetic organic compounds. LC-MS/MS analysis showed a LOD of 3.39 µg kg⁻¹, a LOQ of 10.27 µg kg⁻¹, a coefficient of variation below 7%, and precision between 83% and 101%. BPA was detected in all samples, with a maximum value in P5, 60 times higher than in P3 and up to 8,000 times above global agricultural averages. The distribution of the contaminant was influenced by soil texture, organic matter content, pH, and anthropogenic intensity. These unprecedented results for the southwest of Paraná reinforce the need for public policies aimed at waste control and remediation strategies to preserve soil health and local ecosystems.
