Analysis of Ketoprofen in Fish: Life Cycle Assessment Using Sensors vs. Conventional Methodology

Life cycle assessment (LCA) is a powerful tool to quantify the environmental burdens of different analytical techniques. This work assesses impacts associated with use simple electrochemical carbon paper sensor (CPS) for ketoprofen detection in fish by LCA comparison traditional liquid high-performance chromatography (HPLC) fluorescent detection. The results indicate significant advantages CPS compared HPLC 16 18 analyzed categories impact (ReCiPe2016(H) method), average values 26% lower than HPLC. due, higher relevance, electric energy consumption during “Analysis” step and, secondarily, acetonitrile as mobile phase. On an annual basis, saves 333 kg 1.4 dichlorobenzene equivalents (1.4 DCB eq) non-carcinogenic and 6.9 eq carcinogenic human toxicities, 43.6 oil fossil resources, 91.4 CO2 greenhouse gas emissions high capital investment, maintenance costs, reagents quantities required mitigate economic competitiveness this technique rapid less complex portable device under studied conditions.
