Microplastics have been proven to be pollutants in several stream systems, surface wells, and sea. The presence of microplastics is not spared from human activities on land by using plastic for daily activities. In marine waters, microplastics with a small size (<5mm) can contribute to the food supply chain, especially food sources from the sea and lead to humans on land.
