Description	Este estudo focalizou o fracionamento da mistura de hidrocarbonetos policíclicos aromáticos e seus derivados, especialmente derivados nitrados, encontrados no solo e em extratos de poeira de beira de estrada. Foi utilizada cromatografia líquida com coluna de sílica gel aberta. Diferentes volumes de hexano, hexano:diclorometano (1:1 e 4:1, v/v), diclorometano e metanol foram usados para a eluiçao de fraçoes individuais. O aumento do volume de hexano nao foi suficiente para separar completamente uma pequena fraçoo polar da fraçao aromática. O aumento do conteúdo de hexano na mistura de eluiçao melhorou a separaçao do grupo dos compostos alvos. Extratos de poeira de beira de estrada e do solo foram obtidos pelo uso de um solvente extrator pressurizado com diclorometano como solvente de extraçao. Os limites de detecçao do método variaram de 50 a 220 pg para cada nitro-PAHs, injetado no cromatografo gasoso.
