Greenness assessment of analytical methods used for antibiotic residues determination in food samples

Food of animal origin plays an important role in ensuring a healthy and sustainable human diet. However, residues of pharmaceuticals, especially antibiotics, can be the cause of many health problems. To protect consumers and improve food quality, analytical methods used to determine contaminants should be simple, selective, and have high throughput and low detection limits. Recently, greenness metric tools have proven useful in evaluating analytical procedures and assessing their impact on the environment and sustainable development. The Analytical GREEnness metric (AGREE) was applied to evaluate the green profile of liquid- and solid-phase extraction procedures used to determine antibiotic residues in food samples. The comparison of the procedures was performed for tetracycline antibiotics, due to their broad application in animal husbandry. The twelve input variables of AGREE were compared for each procedure and the total score was evaluated to show the overall impact into the greenness improvement.
