The contaminating chemicals are polybrominated diphenyl ethers (PDBEs), a form of brominated flame retardant. They are used as flame retardant additives in many computers, TVs and household textiles. The Swedish research found that PDBEs were present in the blood of office workers who use computers, and also in hospital cleaners and workers at an electronics-dismantling plant. The highest levels were in the latter, demonstrating the role of electrical goods in the contamination.
Research has shown that low level exposure of young mice to PDBEs causes permanent disturbances in behaviour, memory and learning. PDBEs have also been shown to disrupt the thyroid hormone system, a crucial part of the development of the brain and body.Contamination of human breast milk by PDBEs is rising fast [4].
The River Tees has recently been shown to be heavily contaminated with PDBEs, downstream of a Great Lakes Chemical Company plant at Newton Aycliffe, County Durham, which has manufactured PDBEs [5].
The World Health Organisation has called for these chemicals “not to be used where suitable replacements are available” [6], yet they are still in widespread use - and there is no labelling to warn consumers. Some computer companies, such as Dell, have announced that they are intending to get rid of them [7], but this is the tip of the iceberg.
Dr Michael Warhurst, Toxics Campaigner at Friends of the Earth said:
“This research confirms the need for these chemicals to be
replaced with safer alternatives. This should happen now where alternatives
are available - the bleating of the chemical industry and their servants
in the DTI must be ignored.Consumers must be given a Right to Know what
chemicals are in products, but the Government must also act to get rid
of nasty chemicals.”
