This powerpoint presentation outlines a study on pharmaceutical chemical contamination in surface water. Topics covered include: estrogen hormones; adverse ecological effects; effect of effluents from wastewater treatment plants; sources of estrogen; compounds of interest; analytical methods; free estrogen methods; percentage recovery and RSD of
SPE - GC/MS Analysis; detection limits (ng L<sup>-1</sup>); Presence of Emerging Contaminants
in Surface Waters; stream sampling; and, PNEC Values of Hormones and
Observed Concentration Range. The second part of this study examined the aqueous phase destruction of pharmaceutical chemical contamination using ultrasound. Topics covered in this section include: Schematic and Picture of Sonication
Unit; experimental system conditions; batch system equations; rate constant vs. pH; peroxide effects - degradation percent
with time; hydrogen peroxide effects -
dosage and pH; effect of alkalinity; process conditions; continuous flow reactor - mass balance; correlation between molecular weight
and first order degradation rates; Predicted vs. Observed Degradation; and, future/on-going work. Includes 4 references, figures.
