This powerpoint presentation begins by providing a brief overview of the formation and fate of chlorinated
pharmaceutically active compounds during
wastewater disinfection in Canada. Research objectives included the following: investigate the kinetics of degradation for
selected PhACs when reacted with chlorine in
pure water samples;
determine kinetics of formation of byproducts; and,
investigate PhAC degradation and byproduct
formation in actual wastewater samples. Presentation summary includes the following:
potential for chlorinated byproduct formation exists due to
current disinfection strategies;
experiments in lab water show pseudo-first order kinetics
for Gemfibrozil, Naproxen, Diclofenac, and Ibuprofen;
chlorinated gemfibrozil byproducts formed by zero order
kinetics with respect to themselves, generally fit model for
parallel reactions;
wastewater trials to date show degradation of Gemfibrozil,
but no formation of byproducts; and,
to date, no toxicity data exists on chlorinated byproducts. Includes tables, figures.
