Microplastics are practically ubiquitous contaminants in all environments on the planet. Therefore, present work aimed to investigate microplastic contamination lettuce, chives, and cilantro sold Itacoatiara, Central Amazon, Brazil. Samples of each vegetable were acquired from different commercial establishments. The samples washed with filtered distilled water remove any particles surface vegetables. Hydrogen peroxide was added used wash vegetables digest organic materials. solution stirred daily kept an oven at 60°C. separated using density difference technique. In total, 247 recorded. There no significant number per sample three types size also did not differ significantly between vegetables, smallest (0.067 mm) largest (4.865 being found lettuce. proportion colors recorded varied significantly. Blue red predominant, a greater abundance blue (n=207; 83.8%). particle formats, fibers (n=235; 95.1%) more representative than fragments (n=12; 4.9%). Thus, it can be confirmed that Amazon contaminated, consequently unsafe for direct human consumption, require washing plenty running eliminate before consumed fresh.
