Microplastics (MP) are widespread pollutants that pose a risk to soil ecosystems globally, especially in agricultural soils. This study introduces method extract and identify MP Brazilian tropical soils, targeting debris of low-density polyethylene (LDPE) polyvinyl chloride (PVC) polymers, commonly present settings. The involves removing organic matter extracting using density separation with three flotation solutions: distilled water, NaCl, ZnCl2. Extracted then analyzed through optical microscopy Fourier transform infrared spectroscopy. removal efficiency ranged from 46% 89%, depending on the initial content soil. Recovery rates for LDPE 81.0% 98.8%, while PVC samples showed range 59.7% 75.2%. Finally, this methodology was tested four raw (i.e., without any polymer enrichment) values found were 2517.5, 2245.0, 3867.5, 1725.0 items kg−1, ferralsol, nitisol, gleysol, cambisol samples, respectively, having diverse shapes including fragments, granules, films, fibers. approach lays groundwork future studies behavior
