Despite technological advances in water purification, humanity remains vulnerable to a tiny but extremely persistent threat: microplastics. These are invisible plastic particles that are formed as a result of the breakdown of plastic household items: clothing, kitchen utensils, hygiene products. They do not decompose completely, but accumulate in soil, water - and ultimately, in our bodies.
Over the past decades, more than 9 billion tons of plastic have been produced worldwide. And a significant portion of this material eventually breaks down into micro-fragments that none of the existing treatment technologies can completely remove from drinking water. Treatment plants reduce the concentration, but they do not solve the problem fundamentally. That is why microplastics return to the environment again and again - and to our tables.
According to ecologist Un-Jung Kim of the University of Texas, even a simple action, such as drinking a glass of water, can mean contact with potentially dangerous microparticles. They not only accumulate in the body, but can also carry toxic impurities from wastewater. The consequences are cardiovascular diseases, hormonal disruptions, and oncology.
Another problem is the lack of a clear standard. The world has no single definition of what constitutes microplastic, and no agreed-upon methods for measuring its levels in water. This prevents governments from effectively regulating pollution, and manufacturers from being held accountable for their contribution to the problem.
Environmental chemist Jenny Kim Nguyen calls for universal testing standards to objectively assess the scale of the threat. But the researchers also say society must act. Consumers can reduce their plastic footprint by choosing textiles made from natural fibers and avoiding single-use products.
Microplastics are a problem that is invisible, but which is bringing humanity closer to an environmental and health catastrophe every day. And if we don't act today, tomorrow will be too late.
