This powerpoint presentation begins by providing a brief overview of emerging contaminants such as Pharmaceuticals and Personal Care Products (PPCPS), Pesticides and
Endocrine Disruptors (EDCs). Overall study objectives were to: determine spatial and temporal variations of PPCPs,
EDCs and pesticides in the Montreal area;
identify the main sources of contamination; and,
verify contaminants removal by ozonation in lab. Specific objectives were to: assess oxidation kinetics in natural waters; and,
determine if benchscale
results would predict fullscale
removal data from previous sampling campaigns. Methodology presented includes: target compounds; analysis by online
SPE and LCMS/
MS; two types of filtered water; compounds spiking;
ozone dosages;
room temperature;
compound analysis;
addition of tert butanol
(50 mM); and,
ozone decay. Presentation conclusions indicate the following: ozone is highly effective for removing PPCPs and EDCs
(contaminant structure, CT value);
pesticides - advanced oxidation process (AOP);
caffeine removal at benchscale
was similar to removal
observed in fullscale
WTP;
contribution of all processes at fullscale;
cytostatic agent - environmental issue; and,
ozonation byproducts
should be identified - potential
impact and (eco)toxicological effects. Includes table, figures.
