Abstract：
:In the present study, spiking was used as a strategy to evaluate the mutagenicity of individual compounds in a mixture. Mutagenicity of individual polycyclic aromatic hydrocarbons (PAH) was evaluated in an organic extract of diesel exhaust particles (DEP). The particles were extracted with dichloromethane (DCM). After replacing DCM with dimethylsulphoxide (DMSO), the extract was spiked with four individual PAH: benzo(a)pyrene, benzo(a)anthracene, pyrene and fluoroanthene. The PAH were added separately and in various combinations to the extract to determine the effects of each variable and to identify possible interactions between the individual PAH and between the PAH and the extract. The study was designed as a fractional factorial experiment with the five variables (the DEP extract and the four PAH), giving 16 (instead of 32) mixtures plus a triplicate centrepoint and background, i.e. a total of 20. The fractionated factorial design used in the present work supports a model with linear and interaction terms. The mixtures were tested for mutagenicity in the Ames assay using four strains of Salmonella typhimurium in the presence of rat liver xenobiotic enzymes (S9-mix). Projections to Latent Structures (PLS) was used to quantify the mutagenicity of each compound and possible interactions. The four individual PAH and the DEP extract acted additively in the Ames test with 10% S9-mix.
