Special Issue Information

Dear Colleagues,

Analytical protocols for the analysis of chemicals and their metabolites in water matrices continue to be an active research area closely related to environmental quality and safety. Environmental water contaminants of recent concern are pharmaceuticals, estrogens, and other endocrine-disrupting chemicals. In addition, pesticides, microorganisms, and humic substances (HS), in their function as vehicles for contaminants and as precursors for byproducts in water treatment, traditionally play an important role. In this field, mass spectrometry (MS) and its combination with chromatographic techniques has proved to be highly successful in gaining reliable data about the presence and abundance of contaminants and their metabolites in water matrices. This Special Issue in Water is devoted to manuscripts (research, reviews, short communications) describing methods for qualitative and quantitative analysis of chemicals in all types of environmental water bodies over time and space using mass spectrometry (MS) and tandem MS (MS/MS). We also anticipate an emphasis on the present status of the application of hyphenated techniques (LC-MS, GC-MS, etc.) for the determination of water contaminants, especially transformation products.

Considering the adverse effects of gasoline additives and aromatic compounds on the quality of the water supply and the ecological environment of the water, a methodology, with short chromatographic separation time (22.5 min) and high separation quality, was optimized for the determination of 11 common gasoline additives and aromatic compounds using gas chromatograph coupled with triple quadrupole mass spectrometer (GC–QqQ–MS/MS) system. The extraction procedure of analytes was performed by headspace solid–phase microextraction (HS–SPME) and purge and trap (P&T), respectively. Both of the two extraction methods provided excellent chromatographic resolution in subsequently GC–QqQ–MS/MS detection system, with the coefficients of linear regression of the calibration curves with HS–SPME and P&T pretreatments were 0.9965~0.9998 and 0.9961~0.9999, respectively, n = 7. The limit of detections (LODs) of these selected oxygenate compounds were discovered to be 0.52~32 ng/L in the P&T–GC–QqQ–MS/MS detection system and 0.11~151 ng/L in the HS–SPME–GC–QqQ–MS/MS detection system. For benzene, toluene, ethylbenzene and xylene isomers (BTEX), the HS–SPME–GC–QqQ–MS/MS system provided outstanding detection performance because of the lower LOD obtained. However, for other selected compounds, the P&T–GC–QqQ–MS/MS system offered lower LODs. The proposed extraction–detection procedure is a simple and sensitive analytical approach for the detection of gasoline additives and aromatic compounds in water. Full article
