Over the past decades more and more attention is paid to pollution and its negative environmental impacts. In the thesis I focused on microplastic and its removal from wastewater by using constructed wetlands. Microplastics are plastic particles smaller than 1 mm. They occur in wastewaters in form of microbeads from cosmetic products, fibres released during washing of synthetic clothes and as fragments from discarded plastic products. Many researches have focused on removal of microplastics from wastewater in conventional biological wastewater treatment plants. However, the removal efficiency of constructed wetlands is understudied. Based on the preliminary results, it can be concluded that constructed wetlands are very effective for the removal of microplastics in the short term. In the future, the focus should be on determining the long-term capacity of constructed wetlands to remove microplastics and the potential for degradation/fragmentation of microplastics under these conditions.
