Alternative methods proposed to detect pesticides and antibiotics in water and natural food

Water or food of natural origins (from plants or animals) that we consume on a daily basis can contain unwanted supplies for our organism, such as pesticides or antibiotics. A doctoral thesis carried out by Jorge Juan Soto Chinchilla, from the Department of Analytical Chemistry Department of Analytical Chemistry, at the University of Granada (Universidad de Granada) University of Granada, and directed by professors Ana Mara Garc a Campaa and Laura G miz Gracia, proposes new analysis methods for the detection of pesticide residue (carbamates) and antibiotic residue (sulfonamides) in water, plant foods and food of animal origin (milk and meats from varied sources). These new methods constitute a routine analysis alternative to the analysis used until now. Research forms part of several projects financed by the Spanish National Institute for Agrarian and Alimentary Research (INIA) and the Ministry of Education and Science, in collaboration with the company Puleva Biotech.

The main goal of the work New analytical methodologies, under quality criteria, for the determination of pharmaceutical residues in waters and food, carried out by the research group Quality in Food, Environmental and Clinical Analytical Chemistry (FQM-302), has been to develop new methods to detect residues in food of these contaminants below the Maximum Residue Levels (MRL) established by the European Union, in order to guarantee the quality of the product and permit its distribution and consumption. Researchers point out, regarding water, that the interest caused by control of residue levels of pesticides, which can be found in water as a result of treatment of crops with such compounds, is widely known. However, concern on detecting pharmaceutical residue, specifically antibiotic, is quite recent. The presence of these contaminants in fresh waters can cause a certain bacterial resistance or allergic reactions in
