Greenhouse farming as a source of macroplastic and microplastics contamination in agricultural soils: a case study from Southeast-Hungary

Greenhouse plastic contaminations in agricultural soils were studied to quantify and examine the macroplastic microplastic contaminants on soil surface, profile, groundwater under greenhouse farmland. Random sampling was used select three areas a farm where data collected. Four composite samples collected from shallow (0–20 cm) deep (20–40 for each point, respectively. Three profiles dug, at intervals of 20 cm. Groundwater also same depth 100 Microplastics extracted using predigestion organic matter with 30% H 2 O density separation ZnCl . The total mass macroplastics farmland 6.4 kg ha –1 Polyethylene polyvinyl chloride dominant structures, sizes 1–5 0.5–1.0 cm, Overall, average abundance microplastics 225 ± 61.69 pieces/kg, size structure 2–3 mm. concentrations depths 0–20 20–40 cm 300 93 150.0 76.3 concentration 2.3 pieces/l, fibers structure. Given that found soil, profiles, groundwater, we recommend careful cleaning disposal plastics further research shed light level contamination groundwater.
