Their pervasiveness has led to increasing human exposure, and their recent detection in human blood raises alarming concerns about systemic bioaccumulation and long-term health effects. Moreover, their adverse impact on biological systems, particularly on gastrointestinal, immune, and vascular health, has also become a growing concern as discussed in this review. ——————————————————————————————— Introduction: Microplastics have become ubiquitous in the global environment and are now recognized as a significant emerging pollutant. Recent studies indicate that microplastics can enter the human body through multiple exposure routes, including ingestion via food and water, as well as inhalation of airborne particles. Once inside the body, these particles can induce a range of adverse health effects, including oxidative stress, immune dysregulation, and developmental abnormalities. Although research is still evolving, the detection of microplastics in critical biological matrices such as placental tissue and breast milk underscores the potential for systemic exposure and raises pressing public health concerns (Luo et al., 2019 )¹. Recent studies have consistently reported the widespread presence of microplastics in various environmental matrices and human biological samples. Human exposure to microplastics can occur via multiple routes, including oral ingestion, inhalation, and dermal contact. Emerging evidence suggests that such exposure may induce a range of adverse health effects, such as oxidative stress, DNA damage, organ dysfunction, metabolic disturbances, immune dysregulation, neurotoxicity, and reproductive and developmental toxicity. Furthermore, epidemiological investigations have suggested potential associations between chronic diseases and microplastic exposure, underscoring a growing public health concern regarding their long-term biological effects [1].
