    Assessment of polyaromatic hydrocarbons and pesticide residues in domestic and imported pangasius (Pangasianodon hypophthalmus) fish in India
    (Society of Chemical Industry, 2015) Chatterjee, N.S.; Banerjee, K.; Utture, S.; Kamble, N.; Madhusudana Rao, B.; Panda, S.K.; Suseela Mathew
    The pangasius catfish (Pangasianodon hypophthalmus) is a ubiquitous item of seafood in global markets. However, pesticide residues in aquaculture fish, arising from agricultural run-off and/or direct application during pond preparation, pest control and harvest, are a potential food safety concern. This study assessed the level of chemical hazard in domestic and imported pangasius fish in India. A total of 119 contaminants, including polyaromatic hydrocarbons (PAHs), organochlorines (OCs) and other groups of pesticides, were screened in 148 samples during 2014–2015 as the first endeavour of its kind in an Indian context, employing a validated gas chromatography/tandem mass spectrometry (GC/MS/MS) method. Apart from the low-level incidence of OCs, pesticides such as quinalphos, malathion, parathion-methyl, etc.weredetected in38%of the samples. Incomparisonwith Indian pangasius, fewer contaminants at low residue level were detected in pangasius fillets imported from Vietnam. The human dietary exposures of the residue concentrations detected were less than the maximum permissible intakes and hence appeared safe. However, detection of commonly used pesticides indicated their direct application in aquaculture and contamination from agricultural run-off. This emphasizes the need for continual residue monitoring in aquaculture fish.

    Multiresidue analysis of multiclass pesticides and polyaromatic hydrocarbons in fatty fish by gas chromatography tandem mass spectrometry and evaluation of matrix effect
    (Elsevier, 2015) Chatterjee, N.S.; Utture, S.; Banerjee, K.; Ahammed Shabeer, T.P.; Kamble, N.; Suseela Mathew; Ashok Kumar, K.
    This paper reports a selective and sensitive method for multiresidue determination of 119 chemical residues including pesticides and polyaromatic hydrocarbons (PAH) in high fatty fish matrix. The novel sample preparation method involved extraction of the target analytes from homogenized fish meat (5 g) in acetonitrile (15 mL, 1% acetic acid) after three-phase partitioning with hexane (2 mL) and the remaining aqueous layer. An aliquot (1.5 mL) of the acetonitrile layer was aspirated and subjected to two-stage dispersive solid phase extraction (dSPE) cleanup and the residues were finally estimated by gas chromatography mass spectrometry with selected reaction monitoring (GC–MS/MS). The co-eluted matrix components were identified on the basis of their accurate mass by GC with quadrupole time of flight MS. Addition of hexane during extraction and optimized dSPE cleanup significantly minimized the matrix effects. Recoveries at 10, 25 and 50 lg/kg were within 60–120% with associated precision, RSD < 11%.
