 It is currently unclear if this contamination is affecting human health, but if the water is also found to contain nano-particle pollutants, there could be adverse impacts on human well-being, according to scientists associated with the study.However, plastic tap water pollution remains under-studied, as are the links of how pollution transfers between humans, air, water, and soil.it was estimated that there was approximately 150 million tonnes of plastic pollution in the world's oceans, estimated to grow to 250 million tonnes in 2025.
