polybrominated diphenyl ethers (PBDEs) released to environment PBDEs are a group of flame retardants that are often used in electronics. They are classified by the number of bromine atoms within the molecule
PBDEs are Emitted to The Environment The lower the number of congeners (possible PBDE compounds), the more readily the PBDE will partition into air. The higher the degree of bromination, the more readily PBDEs will partition into water. PBDEs can also be emitted through sediment which is carried to aquatic environments via storms and wind.
PBDEs are Bioaccumulated Plants and marine life absorb or eat the PBDEs. The lower the congener number, the lower the molecular weight of the PBDE, and the easier it bioaccumulates.
Microalgae and aquatic plants
Fish
Damages Anti-Oxidant Defense System
Inhibits Photosynthesis
Shortage of Cellular Energy
Limits Cell Division and Growth
Increases Mortality
Increases or Decreases Swimming
Decreases Sperm or Egg Production
Spontaneous Movement of the Embryo
Loss of Biodiversity If fish and marine life die while in the embryotic stage, dies because of malformations, or dies because its behavioral changes cause it to be easier prey, the population of that species will decrease. Decreasing the population of a species could put it at risk of becoming extinct.
Loss of Biodiversity If aquatic organisms are not able to grow and create energy, or are affected by other diseases due to PBDEs, they will not thrive and biodiversity will be decreased.
