5. Effects on Plant Physiological Processes
The presence of microplastics in soil can disrupt key plant physiological processes, including photosynthesis, water uptake, and nutrient assimilation.
Studies, such as those found in Science of The Total Environment, reveal that plants exposed to microplastics often exhibit reduced chlorophyll content and impaired water transport.
These physiological stressors can ultimately translate into lower crop yields and diminished quality, threatening agricultural productivity and food security.
