Identification and structural elucidation of ozonation transformation products of estrone.

ABSTRACT:

Background

Quantitative methods for the analysis of contaminants of emerging concern (CECs) are abundant in the scientific literature. However, there are few reports on systematic methods of identification and structural identification of transformation products. For this reason, a new method based on high-resolution mass spectrometry and differential analysis was developed in order to facilitate and accelerate the process of identification and structural elucidation of transformation products CECs. This method was applied to the study of ozonation transformation products (OTPs) of the natural hormone estrone (E1).

Results

A control compare trend experiment consisting in the comparison of a control sample to several samples having been exposed to decreasing concentrations of
