What do we know about particles of plastics in humans?

Particles of plastics being detected in humans in one study highlights a significant area of concern in environmental health. This finding suggests that microplastics, which are tiny plastic fragments resulting from the breakdown of larger plastic items, can enter the human body through various pathways, such as ingestion or inhalation. The presence of these particles raises questions about their potential health effects, which are still being researched.

Understanding that particles have been found within human bodies has prompted further investigation into the sources of microplastics and their biological impacts. While it's known that some materials in the human body can be harmless or even beneficial, the identification of plastic particles does not support that they play a positive role in health or are absorbed in a way that is beneficial to human physiology. Instead, the focus is on understanding their origins and potential risks to human health. This makes the finding in the study particularly relevant as scientists and health officials seek to understand the implications of these discoveries.
