Recent studies have highlighted the pervasive presence of microplastics in human bodies, with every human placenta tested showing traces of these particles. The research, involving 62 placental tissue samples, identified polyethylene—the material commonly used in plastic bags and bottles—as the most frequent type of plastic found. The alarming findings were further supported by another study that detected microplastics in all 17 human arteries examined, suggesting a possible link to vascular blockages.

These discoveries add to the growing evidence of microplastics’ spread within the environment and their entry into the human body, with previous studies having found these particles in human blood, breast milk, and faeces. The potential health effects of microplastics on humans, especially unborn babies, are of significant concern, although the full impact remains uncertain. Laboratory research has demonstrated that microplastics can cause damage to human cells.

The studies, led by Professor Matthew Campen, reflected deep concern over the health implications of widespread microplastic contamination, hinting at a contribution of these particles to a range of health issues. Global plastic production continues to escalate, exacerbating the microplastic pollution crisis. This situation poses a dire threat to mammalian life on Earth, with humans consuming and inhaling up to 211,000 microplastic particles annually.

Further highlighting the urgency of the issue, the research also drew connections between microplastics and increasing incidences of diseases such as inflammatory bowel disease and colon cancer in individuals under 50. Conducted by researchers and published in the Toxicological Sciences journal, the study utilized chemical analysis to identify the presence of various microplastics, including PVC and nylon, in placental tissue samples. The omnipresence of microplastics in the environment underscores the critical need for extensive research into their long-term effects on human health and the environment.
