V originále
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. Uma quantidade significante de 1-nitropireno foi detectada em amostras reais coletadas próximas ao centro de Brno.
In Czech
This study was focused on the fractionation of the mixture of polycyclic aromatic hydrocarbons and their derivatives, especially nitrated derivatives, found in soil and roadside dust extracts. Liquid chromatography with an open silica gel bed was used. Different volumes of hexane, hexane:dichloromethane (1:1 and 4:1, v/v), dichloromethane and methanol were used for the elution of individual fractions. Increasing volume of hexane was not sufficient for complete separation of a slightly polar fraction from the aromatic fraction. Increasing content of hexane in the elution mixture improved the separation of the group of target compounds. Soil and roadside dust extracts were obtained by using a pressurised solvent extractor with dichloromethane as the extraction solvent. Detection limits of the method ranged from 50 to 220 pg of individual nitro-PAHs injected into gas chromatograph. A significant amount of 1-nitropyrene was detected in the real samples collected close to the Brno centre.
