5.8 Appendix 3: Overview analysed samples and applied 
techniques 
Table 49 and Table 50 summarises all available information about samples such as 
sampling site, sampling date, species, gender, pooled individuals and applied measuring 
techniques for both screening, final quantification as well as determination of formula 
and congeners group patterns.
