Determination of Chemical Contaminants in Indian prawns by Fast GC-MS/MS using modified QuEChERS as an extraction method

Persistent Organic Pollutants (POPs) like poly-aromatic hydrocarbons (PAH), poly-chlorinated biphenyls (PCB), organochlorines (OC) and agricultural pesticides like organophosphorus (OP) and synthetic pyrethroids (SP) are ubiquitous environmental contaminants due to various anthropogenic activities. Many of these contaminants in addition to being endocrine disruptors are lipophilic in nature hence capable of bio accumulating in the fatty parts of the organs such as breast milk, blood and fatty tissues. Due to their harmful effects, EU has set strict regulations for these chemicals in all the food products. Since, agricultural runoff, municipality and industrial effuent discharge are the major sources of such contaminants they largely affect the aquatic environment and marine habitat. Hence for marine food products like fish, EU-MRLs for most of the contaminants are set as 10 ng/g. Since, in India marine food industry contributes major part of export, it is need of the hour to have validated multi-residue method for qualitative and quantitative monitoring, especially for Indian prawn (Fenneropenaeus indicus). Due to inadequate number of approved testing facilities and high number of samples to be tested, sensitive and reliable validated analytical method with high throughput needs to be developed. This study reports development and validation of a fast method for analysis of 95 analytes (including SP, OC, OP, PAH and PCB) in prawns using GCMS-TQ8040 Triple Quadrupole (GC-MS/MS) system from Shimadzu Corporation, Japan. Sample preparation method involved QuEChERS extraction, followed by Solid Phase Extraction (SPE) cartridge clean-up.
