article description
Emerging public health concerns relating to the epigenetic effects of EDCs, along with thereconceptualization of dose response curves, provides a compelling rationale for addressingestrogenically active contaminants in drinking water. These environmental health concerns arenow known to have long lasting impacts, especially on fetal development. For this drinkingwater research, the estrogenic EDC byproducts were identified and the treatment processes werecompared using the dose applied, the number of byproducts formed and the relativequantification of the treatment byproducts. The analytical optimized method presented andimplemented in this research successfully determined the percent degradation of the parentcompound for each disinfection treatment selected. From the resulting data, the chlorination ofEE2 and DES produced the highest percent degradation of the parent compound, with the leastnumber of byproducts. The optimized method decreased sample variability; showed a better fitto a linear calibration with both high and low concentrations of the parent compound; and lowerMQLs and MDLs. Continuing research is needed to help in understanding the completeconsequences of estrogenic endocrine disruptors in drinking water and the inevitable publichealth impact.
