Determination of selected pharmaceuticals in tap water and drinking water treatment plant by high-performance liquid chromatography-triple quadrupole mass spectrometer in Beijing, China.

Environ. Sci. Pollut. Res. Int. 22(3) , 1854-67, (2015)

A simultaneous determination method of 14 multi-class pharmaceuticals using solid-phase extraction (SPE) followed by high-performance liquid chromatography-tandem mass spectrometer (HPLC-MS/MS) was established to measure the occurrence and distribution of the...

Emerging organic contaminants in coastal waters: anthropogenic impact, environmental release and ecological risk.

Mar. Pollut. Bull. 85(2) , 391-9, (2014)

This study provides a first estimate of the sources, distribution, and risk presented by emerging organic contaminants (EOCs) in coastal waters off southwestern Taiwan. Ten illicit drugs, seven nonsteroidal anti-inflammatory drugs (NSAIDs), five antibiotics, ...

Enzymatic characterization of ELOVL1, a key enzyme in very long-chain fatty acid synthesis.

Biochim. Biophys. Acta 1851(2) , 231-7, (2015)

X-linked adrenoleukodystrophy (X-ALD) is a neurometabolic disease that is caused by mutations in the ABCD1 gene. ABCD1 protein deficiency impairs peroxisomal very long-chain fatty acid (VLCFA) degradation resulting in increased cytosolic VLCFA-CoA levels, whi...

High sensitive multiresidue analysis of pharmaceuticals and antifungals in surface water using U-HPLC-Q-Exactive Orbitrap HRMS. Application to the Danube river basin on the Romanian territory.

Sci. Total Environ. 532 , 501-11, (2015)

The occurrence of 67 pharmaceutical and antifungal residues in the Danube river on the Romanian territory was studied by using solid-phase extraction (SPE) and LC-Q Exactive Orbitrap high resolution MS in both full scan (FS) MS and targeted MS/MS modes. A sin...

Ultra-high-performance liquid chromatography-Time-of-flight high resolution mass spectrometry to quantify acidic drugs in wastewater.

J. Chromatogr. A. 1423 , 96-103, (2015)

A novel analytical approach involving an improved rotating-disk sorptive extraction (RDSE) procedure and ultra-high-performance liquid chromatography (UHPLC) coupled to an ultraspray electrospray ionization source (UESI) and time-of-flight mass spectrometry (...

Introduction of human pharmaceuticals from wastewater treatment plants into the aquatic environment: a rural perspective.

Environ. Sci. Pollut. Res. Int. 22 , 10559-68, (2015)

Incomplete removal of pharmaceuticals during wastewater treatment can result in their discharge into the aquatic environment. The discharge of pharmaceuticals in wastewater treatment plant (WWTP) effluents into rivers, lakes and the oceans has led to detectab...

Pharmaceutically active compounds in sludge stabilization treatments: anaerobic and aerobic digestion, wastewater stabilization ponds and composting.

Sci. Total Environ. 503-504 , 97-104, (2014)

Sewage sludge disposal onto lands has been stabilized previously but still many pollutants are not efficiently removed. Special interest has been focused on pharmaceutical compounds due to their potential ecotoxicological effects. Nowadays, there is scarce in...

Determination of pharmaceuticals in bivalves using QuEChERS extraction and liquid chromatography-tandem mass spectrometry.

Anal. Bioanal. Chem 407(13) , 3841-9, (2015)

A method for the quantitative determination of seven pharmaceuticals in bivalves was developed by QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction, followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) with electrospray ion...

Mechanism for enhanced degradation of clofibric acid in aqueous by catalytic ozonation over MnOx/SBA-15.

J. Hazard. Mater. 286 , 276-84, (2015)

Comparative experiments were conducted to investigate the catalytic ability of MnO(x)/SBA-15 for the ozonation of clofibric acid (CA) and its reaction mechanism. Compared with ozonation alone, the degradation of CA was barely enhanced, while the removal of TO...

A solid-phase extraction method for rapidly determining the adsorption coefficient of pharmaceuticals in sewage sludge.

Water Res. 67 , 292-8, (2014)

The partitioning of pharmaceuticals in the environment can be assessed by measuring their adsorption coefficients (Kd) between aqueous and solid phases. Measuring this coefficient in sewage sludge gives an indication of their partitioning behaviour in a waste...
