PET Microparticles Has Severe Toxic Effects to Arabidopsis thaliana in Hydroponic Cultivation

Extended Abstract Plastic microparticles and nanoparticles are growing invisible threat. Estimates speak of a threefold amount of plastics in the year 2050 compared to today. The effect of these particles on aquatic organisms is relatively well mapped, but their effect on plants remains still poorly understood [1]. Plants are the key part of entire human population diet. Microplastics and nanoplastics are known to bind and concentrate harmful chemicals from the environment (POP, toxins, pesticides, PCB etc.), [2]. They increase stress too and especially in plants, they bind to the surface of root fibers [3]. It is estimated that there is such plastic pollution in European agriculture soil as in the North Pacific gyrus [4]. In this study, we have analyzed the effect of bacteria-sized particles on Arabidopsis thaliana , peas ( Pisum sativum L.) and maize ( Zea mays L.) in hydroponic cultivation which eliminates the influence of soil and soil microbiota. The procedure with trifluoroacetic acid was used for the synthesis of PET microparticles (MPs), [5]. The result was particles with a reduction coefficient
