Environmental and Toxicological Perspectives of Soil Microplastics in Northern Nigeria

The study examined the environmental and toxicological implications of microplastics in the soil of Northern Nigeria, which has not been addressed through research. The microplastics, as a product of plastic degradation, have environmental risks and can be recognised as sources of soil decay ecosystem pollutants in increasing numbers. This study aimed to investigate the sources, routes, and ecological effects of microplastics in the soils of Northern Nigeria, and specifically in agricultural activities, waste management, and atmospheric emissions. In its design, the study used a rigorous examination of the secondary information in the form of peer-reviewed publications, institutional monographs, and international media to collect detailed information on the environmental destiny and toxicological dangers embedded in microplastics in the soil systems of the area. Findings reveal that soil microplastics are related to lower soil productivity, malfunctioning microbial functions and disturbance of plant growth, directly posing risks to food security and human health. The results underscore the need to focus on increased research and development, ameliorate waste management strategies, and incorporate sustainable agricultural methods to improve the health of soils and food production in the area. The study recommends establishing effective monitoring systems, capacity building and introducing policies to deal with microplastic contamination in the soil, which is important in safeguarding environmental sustainability and human health.
