Since no analytical methods to quantify the main metabolites of CBX and OLQ were reported yet, the aim of this work was to develop a sensitive and reliable LC-MS/MS method for simultaneous determination of the carcinogenic desoxy metabolites DOLQ and DCBX and the marker residues QCA and MQCA (presented in free form or as glycine conjugates, namely, QCA-glycine and MQCA-glycine, resp.) in swine muscle and liver tissues.
The analytical method developed for determination of the residues of CBX and OLQ and their main metabolites in swine muscle and liver tissues was validated according to the EU Decision 2002/657/EC .
The developed method well fulfilled the requirements for the monitoring of the residues related to CBX and OLQ. The relative standard deviation (RSD) of interday values of the six compounds analyzed by the present method was 5.5-9.2% and for the intraday test was 5.0-7.4% (Table 4).

the correlations between the first-order factors) and when the correlations between the first-order factors of meaningfulness, comprehensibility and manageability were fixed at 1.00 indicating that the OLQ measures SOC as a unidimensional construct.
SEM analysis of cross-lagged longitudinal data, which generated more information not only about unexplored predictive relationships of SOC and work characteristics but also about the structure and the stability of SOC as measured by the 13-item OLQ. The current findings were consistent with other recent work using confirmatory factor analysis that have shown a theoretically based second-order factor structure as an adequate way of constructing SOC (see Feldt, Lesldnen et al., 2000; Feldt et al., 2003; Feldt & Rasku, 1998; Gana & Gamier, 2001; Kivimaki, Feldt, et al., 2000).
