Fiberglass is widely used in the manufacture of boats. This material was considered safe for the environment. But the new analysis showed for the first time that it is capable of breaking down and polluting coastal waters, as well as entering the food chain, Mir24 reports.

Fiberglass particles were detected in the soft tissues of oysters and mussels collected from the operating shipyard in Chichester Harbor (south of England). Using micro-Raman spectroscopy, scientists found 2,740 particles per kilogram in mussels and 11,220 particles per kilogram in oysters.

Fiberglass, used since the 1960s, is known for its durability. But it is extremely difficult to dispose of this material, and it is often simply thrown away. As a result, the smallest particles of glass fall into the water. Together with seawater, they enter the body of filtering creatures such as mussels and oysters.

This is dangerous not only for ecosystems, but also for human health. Mussels and oysters are a common delicacy. The dish is considered healthy, but due to the high content of fiberglass, it can be harmful to health.
