What role do microplastics play in human health, and what are their implications?

Microplastics have emerged as a significant concern for human health due to their pervasive presence in the environment and within human biology.

Studies have found microplastics in various human tissues, including lungs, blood, and even the placenta, indicating widespread exposure. The accumulation of these particles can lead to chronic inflammation and oxidative stress in cells, impacting overall health.

• Microplastics do not break down in the human body, potentially acting like a constant irritant that triggers inflammation.
• They can initiate oxidative stress, analogous to having multiple small fires within the body, which contributes to various health issues.
• The presence of microplastics in newborns' meconium suggests exposure begins in utero, raising critical concerns about developmental effects.

The long-term implications of microplastic accumulation remain a topic of scrutiny, and evidence suggests that they might exacerbate health conditions, including cognitive decline and chronic diseases.
