Determination of Microplastics as a Pollutant of Agricultural Land

Abstract

Bosnia and Herzegovina has not yet established adequate plastic waste management systems, which contributes to the increasing presence of microplastics in soil. Microplastics in soil may affect its physical properties, reduce water retention capacity, and negatively influence plant growth by inducing oxidative stress and reducing seed germination. This study investigates the presence of microplastics in different types of agricultural land (pasture, garden, arable land, mountain soil, and greenhouse soil) within the Tuzla Canton. The results confirmed the presence of microplastics in all analyzed samples. The occurrence and distribution of microplastics were influenced by land use, environmental conditions, and past anthropogenic activities at the sampling sites. Microplastics were identified through microscopic analysis based on particle number, morphology, and color. The detected concentrations ranged from 40 to 80 particles/kg. Although microplastics were present in all samples, no significant adverse effects on agricultural production or the health of humans and animals were observed within the scope of this study. The findings highlight the need for further research and improved waste management practices to better understand long-term environmental impacts.
