The active substances were analysed in the runoff samples and the eluates from the laboratory tests by ultra-high-performance liquid chromatography coupled with UV detection at BAM, and in runoff samples by liquid chromatography coupled with tandem mass spectrometry at MPA Eberswalde.
In the present study a number of predetermined biochemical substances were analysed.
Furthermore, databases and lists of active substances were analysed, such as the register of detergents and cleaning agents of the German Federal Environmental Agency, which provided (product-independent) summary analyses, and the German drug directory "Rote Liste".
The toxicological data for the substances were analysed on the basis of reviews, supplemented by original literature, and summarised and evaluated with respect to the exposure data (for details cf. Hahn et al. [ 16]).
The substance was analysed by the Maritime and Coastguard Agency.
While such results identify the sexual benefits users seek from different substances, additional analyses examined the sexual risks associated with their use.
Also, since many commercially available laxatives are mixture products consisting of two or more pharmacologically active substances, our analyses on the various categories of laxatives are limited due to missing information on the exact composition of these products.
Therefore more open-ended explorative methods could be used e.g. proteomics and metabolomics to gain further insights in the activated mechanisms and based on such analyses determine substances for detailed analyses [ 92, 93].
Mass and energy balances and material and substance flow analyses have been therefore drawn to assess and compare design solutions utilizing two mixed plastic wastes (MPW) obtained from separate collection of plastic packaging, after different levels of pre-treatments.
Mass and energy balances and material and substance flow analyses have been drawn to assess and compare design solutions utilizing a packaging derived fuel (PDF) obtained as scrap by food industrial processes.
