Assessment of the hazards of polybrominated biphenyls.

Abstract: During their peak use period, PBBs represented under 1% of the total sales of fire retardant chemicals, and very probably would have escaped intensive study if they had not been mixed accidentally with animal feed preparations. Instead, international attention was drawn to PBBs by the state-supervised killing of over 35,000 cattle which had been contaminated with PBBs. Interestingly, low doses of PBBs exert a broad spectrum of toxicological, pharmacological, and biochemical effects despite low acute toxicity. … Show more

“…This organohalogenated compound has been previously reported in environmental samples, and it has been detected as a contaminant in organobromine fire retardants 27,28 . This aromatic organobromine compound was not detected in the remaining sites and its origin could be attributed to intensive traffic of fluvial transportation of wood chips between the processing plant located upstream the Valdivia and Angachilla rivers and the Corral Bay.…”

“…20 Sua aplicação se limitou praticamente a termoplásticos (acrilonitrila-butadieno-estireno -ABS) utilizados em equipamentos eletrônicos de uso doméstico e empresarial. 20,21 No Brasil não foram identificados dados sobre o uso do PBBs no passado, nem de sua produção ou existência de estoques. 22,23 Da mesma forma, não foram feitas importações ou exportações destes compostos no período de 1997 a 2015, não existindo dados para os anos anteriores.…”

“…29 Os PBBs ganharam bastante atenção após um acidente em Michigan (EUA), entre 1973 e 1974, quando cerca de 250-500 quilos de FireMaster BP-6 (HxBB) foram acidentalmente adicionados à ração animal, sendo a população local posteriormente exposta através da ingestão de leites e outros alimentos contaminados. 20,30 Como consequência do acidente, a empresa parou de produzir FireMaster BP-6 em 1974 e demais PBBs em 1977. 20,31 Apesar da aplicação dos PBBs ter diminuído desde meados da década de 1970, resíduos dos mesmos continuam sendo reportados em amostras ambientais e em seres humanos de diferentes partes do globo, como China, Espanha e Estados Unidos.…”
