Microplastics enter agricultural soils through sewage sludge, atmospheric deposition, and irrigation. Their accumulation in the soil profile may alter soil physicochemical properties and crop physiology, and, through the food chain, may lead to human exposure to these particles posing a potential health risk. This pilot study aimed to assess the occurrence of potential microplastic in agricultural soils of the Lubelskie Voivodeship (Poland), with particular attention to the morphological characteristics and chemical identity of a subset of them. Six composite soil samples, collected in accordance with ISO 18400-102, were dried, homogenized, and subjected to alkaline-oxidative digestion (KOH/H2O2) to remove organic matter, followed by filtration through GF/F glass-fibre filters. The extracted particles were examined using an infrared microscope and classified into four morphological categories. In total, 108 particles were morphologically identified as potential microplastics using an infrared microscope, and their abundance ranged from 107 to 294 particles kg-1 dry soil (mean 197 ± 62 particles kg-1). Irregular fragments predominated (57.4%), while fibres, compact/rounded particles, and flat, film-like particles occurred at lower and comparable frequencies (12.0-16.7%), with the proportion of each shape category varying between soil batches. Chemical identification by FT-IR spectroscopy, performed on a subset of 27 particles (25.0% of the total), large enough for ATR measurement, confirmed the presence of polyethylene, poly(vinyl chloride), polypropylene, and polyethylene terephthalate. The results indicate the presence of potential microplastics in all analyzed samples, and highlight the need for further research, based on a larger number of samples, into their effects on soil quality, environmental safety, and human health.
