Microplastics (MP) are small plastics (0.001 mm to 5 mm). These are divided into two categories: the primary ones, which maintain a defined size since their manufacture, and the secondary ones, which arise from the degradation of larger plastics. These represent an emerging threat to ecosystems and biota due to their small size, since they can be ingested by a wide variety of organisms, thus affecting food chains; in addition to having long periods of degradation in the environment, having a contaminating potential (1,2). Various investigations have shown that MPs can be released into terrestrial ecosystems, including agroecosystems, through various pathways, such as runoff, application of biosolids, and atmospheric deposition (3). In the future, MPs may represent a problem for various crops, including potatoes. This is due to the use of various polymeric agricultural materials, mainly composed of polyethylene (PE). These materials are used in the manufacture of greenhouse covers, agricultural meshes, germination trays and plastics for mulching that are used in various activities (4). Many of these implements wear out due to exposure to UV rays, mechanical abrasion and other factors, causing them to fragment into smaller particles. These microplastics are classified as secondary plastics (5). It has been proven that PE MPs directly affect crops through various mechanisms of absorption and translocation of plastic particles in plants, such as apoplastic pathways (5). However, there are no specific studies that address the impact that PE MPs have on the development of potato crops. Addressing this issue is crucial, given that Peru is the leading producer of this tuber in Latin America(6). Therefore, this work aims to demonstrate the translocation process and explore the effects of the bioaccumulation of PE MPs distributed in the range of 0.001 mm to 5 mm, and its implication in the growth and germination processes of this tuber (7).
