Influence of grain size distribution of compost from urban greenery on the distribution of microplastics and their leachability

Original language description

Microplastics have been found in composts made from urban greenery: polyethylene terephthalate (PET) &gt; polystyrene (PS) &gt; polyethylene (PE) &gt; polypropylene (PP). Microplastics and additives are most concentrated in composts in the 0.63-1.25 mm grain size class. Additives in dry matter of compost represent 0.11-0.13% of microplastics. A maximum of 15% of the total content of chemical compounds in the dry matter passes into the aqueous leachate. The leachability of additives from compost is higher than the leachability of chemical compounds from polymers. The leaching of additives in the 0.63-1.25 grain size class affected the germination index of the watercress.
