Impact/Purpose:
The objective of the present study was to systematically investigate the interactions between the estrogens (E1, E2, E3, and EE2), TEST, AND and PROG, and the solid components of synthetic wastewater. Specifically, the goals were to confirm the occurrence of abiotic transformation of estrogens in the presence of vegetable material, and to model this process. The knowledge obtained here will establish the basis for the optimization of wastewater treatment technologies based on the enhancement of this transformation mechanism.
Description:
The abiotic transformation of estrogens, including estrone (E1), estradiol (E2), estriol (E3) and ethinylestradiol (EE2), in the presence of model vegetable matter was confirmed in this study. Batch experiments were performed to model the catalytic conversion of E1, E2, E3, and EE2 in synthetic wastewater. Greater than 80% reduction in the parent compounds was achieved for each target chemical after 72 h with the remaining concentration distributed between aqueous and solid phases as follows: 13%, and 7% for E1, 10% and 2% for E2, 6% and 2% for E3, and 8% and 3% for EE2, respectively. Testosterone, androstenedione and progesterone were also monitored in this study, and their concentrations were found to be in agreement with initially spiked amount. Data collected under laboratory conditions provided the basis for implementing new abiotic wastewater treatment technologies that use inexpensive materials.
