Bioanalysis Young Investigator
No full text Supervisor’s supporting comments It gives me great pleasure to nominate Shivani Tanwar, a National Science Council, Taiwan postdoctoral fellow presently at National Taiwan University (Taiwan) for the Bioanalysis: Young Investigator 2011 award. She joined my laboratory in 2006. I have found her very diligent with high academic interests and intellectual ability. She is highly motivated and self driven for research work with the ability to design new experiments. Shivani is a promising scientist, motivated to work in multidisciplinary research areas and quite capable of setting up her own team and carrying out independent research. She is quite efficient at training her juniors. She belongs to the brightest segment of Indian students. As part of her PhD, she worked on the development of new methods for chiral separation and determination of enantiomeric excess of certain pharmaceutically and biomedically important compounds. In her work she has applied certain fast and de novo reaction techniques, which have been proven to be techniques of immense importance in chiral separation. Shivani had several job offers, but her keen interest for research pushed her to accept the postdoctoral position in Taiwan, and we still now share knowledge and discuss scientific issues today. Shivani deserves this honor. I recommend her name without any reservations. </jats:p

No full textAmong the wide range of emerging pollutants, perfluorinated compounds and various pharmaceuticals, such as nonsteroidal anti-inflammatory drugs, are showing growing concern. These contaminants can be found in freshwater ecosystems because of their incomplete removal during wastewater treatments so, their water solubility and poor degradability result in their continuous discharge and pseudo-persistent contamination. Usually, expected levels of these analytes are particularly low; therefore, sensitive and selective analytical techniques are required for their determination. Moreover, sampling and preconcentration are fundamental steps to reach the low detection limits required. The polar organic chemical integrative sampler (POCIS) represents a modern sampling approach that allows the in-situ preconcentration of ultra-trace pollutants. In this work, a fast liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method was developed for the determination of diclofenac, ketoprofen, mefenamic acid, naproxen, ibuprofen, perfluorooctanoic acid, perfluorooctanesulfonate and caffeine in water for human consumption. The chromatographic separation of analytes was achieved in less than 6 min. Quantitative analysis was performed in multiple reaction monitoring mode using ketoprofen-d3 as internal standard. Two different sites of Northern Italy were studied deploying POCIS for four weeks in both inlet and outlet of two drinking water treatment plants. The evaluation of time-weighted average concentration of contaminants was accomplished after the calibration of POCIS; to this aim, the sampling rate values for each compound were obtained by means of a simple calibration system developed in our laboratory. Ketoprofen, perfluorooctane sulfonate, perfluorooctanoate and caffeine were measured in both sites at the ng l−1 level. Copyright © 2016 John Wiley & Sons, Ltd
Occurrence of PCPs in Natural Waters from Europe
No full textIn the framework of the study of emerging pollutants in the aquatic environment, personal care products (PCPs) play a relevant role as they are used in everyday life. They are continuously introduced into the natural water compartment, mainly through treated and untreated sewage but also via different pathways. This chapter describes the "state of the art" of the distribution and impact of PCPs on European natural waters (rivers, lakes, groundwater, drinking water, etc.). An extensive review of the recent literature has been carried out, gathering together the most relevant studies and presenting the results in five sections: fragrances, UV filters, detergents, preservatives, and repellents. In each section, data on the main molecules employed in PCP formulations are reported and compared. The physicochemical properties of many PCP compounds are summarized in the respective tables along with an additional table listing the measured concentrations of all PCPs detected in waters all over Europe
