Resumo
Os retardantes de chama são amplamente utilizados em plásticos, têxteis, móveis, automóveis e principalmente em compostos eletrônicos. Eles são elementos importantes para retardar a propagação das chamas e diminuir as chances de acidentes mais graves. No passado, utiliza-se em grande escala como retardantes de chamas as bifenilas polibromadas (PBBs) e éteres difenílicos polibromados (PBDEs), no entanto, estudos recentes realizados mostram que esses compostos apresentam efeitos tóxicos, além disso, são poluentes orgânicos persistentes (POPs) que são resistentes à degradação, bioacumulam e biomagnificam no ecossistema, o que tem preocupado cientistas e órgãos governamentais. Diante disso, muitos países têm reduzido a produção e o uso de retardantes de chama bromados em seus processos. Desta forma, é retratado um levantamento de dados sobre a presença de polibromados em produtos eletrônicos vendidos em mercados populares e reforçando a necessidade da construção de uma regulamentação específica para esses compostos.
Flame retardants are widely used in plastics, textiles, furniture, automobiles and mainly in electronic compounds. They are important elements to slow down the spread of flames and decrease the chances of more serious accidents. In the past, polybrominated biphenyls (PBBs) and polybrominated biphenyl ethers (PBDEs) were widely used as flame retardants. However, recent studies have shown that these compounds have toxic effects, in addition, they are persistent organic pollutants (POPs), that are resistant to degradation, bioaccumulate and biomagnify in the ecosystem, which has worried 2 scientists and government agencies. Therefore, many countries have reduced the production and use of brominated flame retardants in their processes. In this way, a survey of data on the presence of polybrominated compounds in electronic products sold in popular markets is portrayed, reinforcing the need to build a specific regulation for these compounds.
