“…Moreover, these sites repel negatively charged matrices, thus further reducing interferences. This is highly advantageous over solid-phase extractions of steroid hormones from environmental matrixes using either octadecyl (C18)-bonded silica adsorbent or HLB cartridge. Extracts of C18 or HLB often require further clean up by liquid–liquid extraction, solid phase purification on C18/NH2 columns, , silica gel column chromatography, , gel permeation on Biobeads SX-3 columns, high performance liquid chromatography (HPLC) fractionation, , or a combinations of these methods. ,, Intense extraction and clean up procedures increase the potential for mechanical losses of the analyte of interest …”

“…From the amount of flowing river water and the volume of the effluent at this sampling point, 30% of the river water is estimated to be of effluent origin (). Sewage-treatment plants are known to be the major source of E1 and E2 (i.e., human/animal urine origin) in river water ( ). In the Katsura River, an administrative agency's survey detected E1 and E2 with comparable concentrations to ours using an enzyme-linked immunosorbent assay and concluded that the major source is effluent from the sewage-treatment plant ().…”

“…This may be explained by the presence of calcium-sensitive channels on the cell membrane which have a role as gravireceptors (Häder et al 2009). Shishida et al (2000) have tested the quality of different sewage treatment processes of wastewater by means of bioassays. Lake Mariout plays an important economic role in aquatic ecology.…”
