Rapid direct injection LC-MS/MS method for analysis of prioritized indicator compounds in wastewater effluent

Abstract

Trace organic compounds (TOrCs) have been detected in drinking water sources for several years, raising concerns due to their potential risks to public health.

Monitoring and Ecotoxicity Assessment of Emerging Contaminants in Wastewater Discharge in the City of Prague (Czech Republic)

“…The pharmaceuticals with the lowest concentrations quantified in this sampling period were bezafibrate, oxcarbazepine, and triclocarban (11,15, and 17 ng/L respectively), and chloramphenicol was below the LOD. All these contaminants did not exceed the maximum concentration reported in other effluents from WWTPs worldwide, ranging from 262 ng/L to 79.86 µg/L [27][28][29].…”

Predicting trace organic compound attenuation with spectroscopic parameters in powdered activated carbon processes

“…Mass spectrometry was performed with an Agilent 6490 MS system and an electrospray ionization source equipped with Agilent jet stream technology for enhanced sensitivity. Method optimization parameters, compound transitions and relevant QA/QC has been published in previous work (Anumol et al, 2015b). All data analysis and processing was done using the Agilent MassHunter software (Ver.…”

“…Trace organic compounds (TOrCs) comprising of pharmaceuticals, personal-care products, industrial constituents, and others are commonly detected in the aquatic environment and drinking water sources (Focazio et al, 2008;Benotti et al, 2009;Scott et al, 2014).…”

Predicting trace organic compound attenuation by ozone oxidation: Development of indicator and surrogate models

“…Mass spectrometry was performed with an Agilent 6490 MS system and an electrospray ionization source equipped with Agilent jet stream and iFunnel technology. The detailed procedure and information including method optimization parameters, compound transitions and relevant quality assurance/quality control (QA/QC) are available in previous work (Anumol et al, 2015b). All data analysis was performed using the Agilent MassHunter software (Ver.…”

“…Even though current analytical techniques including mass spectrometry are challenging to apply to real-time on-line detection of TOrCs, it is noteworthy that rapid advances in analytical instrumentation and methods including automated sample handling, preparation, and direct aqueous injection enables at-line monitoring of TOrCs Anumol et al, 2015b), which can help the implementation of the developed indicator model for ensuring treatment efficacy in water reuse. Spectroscopic surrogates can also be readily measured without any specialized pretreatment or sample preparation.…”
