PBDEyhdisteet

PBDEyhdisteet, or polybrominated diphenyl ethers, are a group of flame retardants that have been widely used in consumer products to reduce flammability. These chemicals are added to materials such as plastics, textiles, and foams found in furniture, electronics, and building materials. Their purpose is to slow down the spread of fire by releasing bromine atoms that interfere with the combustion process.

The use of PBDEs has raised significant environmental and health concerns. They are persistent, meaning they do not break down easily in the environment and can accumulate in soil, water, and air. They also bioaccumulate, increasing in concentration as they move up the food chain, leading to potential exposure for humans and wildlife. Studies have suggested that PBDEs can interfere with thyroid hormone function and may have neurodevelopmental effects, particularly in children.

Due to these concerns, many types of PBDEs have been phased out or banned in various regions, including the European Union and North America. Manufacturers have been encouraged to find alternative flame retardant chemicals that are considered less harmful. However, the legacy of PBDE use means that these compounds can still be found in older products and in the environment. Ongoing research continues to assess the risks associated with PBDE exposure and to monitor their presence in various environmental matrices.
