The emerging field of microplastics explores the impact tiny plastic particles have on human health. Microplastics (particles 5mm and smaller) and nanoplastics (1mm and smaller), are created directly through manufacturing or indirectly from the degradation of larger plastic materials in the environment. Microplastics have been detected throughout the human body, including in the blood, saliva, liver, kidneys, and placenta.

Research has revealed that nanoscale plastic particles, prevalent in most food and water, can pass from pregnant rats to their unborn offspring and may impair fetal development. Nanoplastics have also been found in upper airways of humans, leading to concerns about long-term exposure and impact on respiratory health.

Considering the widespread presence of microplastics in the environment, understanding how they affect health and developing strategies to mitigate these effects is vital to protecting all communities from harmful effects.
