We studied the effects of TPs at environmentally relevant concentrations along a wide concentration gradient (0￢ﾀﾓ160 mg g￢ﾈﾒ1) and tested the effects on plant growth, soil pH and the key ecosystem process of litter decomposition and soil respiration. The addition of TPs negatively affected shoot and root growth already at low concentrations. Tea litter decomposition slightly increased with lower additions of TPs but decreased later on. Soil pH increased until a TP concentration of 80 mg g￢ﾈﾒ1 and leveled off afterwards. Soil respiration clearly increased with increasing concentration of added TPs. Plant growth was likely reduced with starting contamination and stopped when contamination reached a certain level in the soil. The presence of TPs altered a number of biogeochemical soil parameters that can have further effects on plant performance. Considering the quantities of yearly produced TPs, their persistence, and toxic potential, we assume that these particles will eventually have a significant impact on terrestrial ecosystems.</p> 570 Soil respiration ; Soil pH ; Litter decomposition ; Microplastic pollution ; Tire particles ; Soil Pollution, Control, and Remediation ; Research Article ; Plant growth Litter decomposition Soil respiration Soil pH 500 Naturwissenschaften und Mathematik::570 Biowissenschaften; Biologie::570 Biowissenschaften; Biologie 04 agricultural and veterinary sciences 15.
