 abstract={The effects of leachates from newly-synthesized bioplastics on the early stages of higher plant growth were studied together with the putative identification of the chemicals in the given microbioplastic leachates. Three polylactide-based bioplastics and pure polylactide (PLA) were subjected to the phytotoxicity tests (1) to determine the intrinsic effects of chemicals on the germination and early growth of plants without prior incorporation of the chemicals into a soil and (2) to find the impact of the chemicals introduced into a soil on the germination and plant growth. Plants Sorghum saccharatum, Lepidium sativum and Sinapis alba were used. For two out of four microbioplastics the total ion chromatograms revealed the presence of chemicals in the leachates. Out of 20 individual m/z values, 6 were putatively attributed to the known compounds. Microbioplastic leachates did not affect seed germination and contributed rather to the stimulation than inhibition of the early plant growth. In the soil tests the inhibition of root and shoot growth of dicotyledons occurred more frequently than in the liquid phase tests. It indicates the potential interactions between the chemicals in the leachates and soil matrix. Dicotyledons were more sensitive than monocotyledons in the evaluation of phytotoxicity of microbioplastic leachates.},
