Abstract
The study addresses the issue of microplastic pollution as one of the emerging threats to human health. Special attention is given to the main pathways through which microplastic and nanoplastic particles enter the human body — via drinking water, food, air, and household sources. The mechanisms of microplastic toxicity affecting various organ systems are described, including the digestive, respiratory, cardiovascular, reproductive, and immune systems. It is shown that microplastics are capable of accumulating toxic substances, disrupting hormonal balance, inducing oxidative stress, and triggering inflammatory responses. The work aims to raise awareness and explore ways to minimize the negative impact of microplastics on human health
