Os experimentos de voltametria cíclica com os nitro-PAH foram conduzidos em N,N-dimetilformamida anidra (DMF) contendo perclorato de tetraetilamônio 0,1 mol L-1 (TEAP), usando-se uma célula de três compartimentos, equipada com eletrodos de trabalho e auxiliar de platina e eletrodo de referência de Ag/AgI (fio de prata imerso em DMF / TEAP 0,1 mol L-1, contendo iodeto de tetrabutilamônio 0,05 mol L-1). Esses potenciais podem ser ordenados do menos negativo para o mais negativo, o que corresponde à mesma ordem com que decresce a ação mutagênica direta (3-NF >> 1-NP > 6-NC >> 9-NA). Assim, o 3-NF, que apresentou o potencial de meia-onda menos negativo é, entre os nitro-PAH estudados, o de maior atividade mutagênica. Deste modo, estas propriedades podem ser utilizadas como indicativas do risco à saúde humana da exposição a nitro-PAH, sendo, portanto, de grande importância em estudos toxicológicos.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-01-09T16:05:27Z No. of bitstreams: 1 27051.pdf: 185649 bytes, checksum: 7e93544b332b65594bf5fab5e81d1384 (MD5)Made available in DSpace on 2012-01-09T16:05:27Z (GMT).
