Alternative methods proposed to detect pesticides and antibiotics in water and na...(the consuming population. Innovativ...)

In order to achieve this, the study carried out by the UGR University of Granada, used techniques that have not been much explored in these fields. Cathodoluminiscence detection (CL) connected to Flow Injection Analysis (FIA) and High Performance Liquid Chromatography (HPCL), or Capillary Electrophoresis (CE) with UV/Vis detection using an online preconcentration technique in the capillary itself, or detection via Mass Spectometry (MS). MS can also unequivocally identify the analysed compounds. Research has been specifically based on carbamates, a widely used pesticide family, and on sulfonamides, a group of wide-spectrum antibiotics commonly used in medicine and veterinary science.

Researchers point out that methods developed in this work could be applied in the future to routine analysis for this kind of residue control in plant foods and foods of animal origin, in Quality and Alimentary Safety laboratories, or in the detection of such contaminants in waters of varied sources. These methods definitely constitute interesting alternatives to the already established and less sensitive methods which imply a greater consumption of organic solvents and generate more contaminant residues, the author of the thesis points out.

FQM-302 research group has been working on the proposal of methods of detecting contaminant residues in foods and in the environment for several years. Currently work is being carried out in different doctoral theses which looks at the study of other pesticide families and their degradation products, as well as the study of other antibiotics such as quinolones and beta-lactams using the methods mentioned above.
