  • Evaluation of water quality and bioaccumulation of metals in commercially important fishes: a human health concern
    Aneetta Libiya Job, Nigariga Pasumpon, Rahul Varma, Sugumar Vasudevan
    Environmental Geochemistry and Health, 2023
    The present study aimed to determine the physicochemical properties of the coastal water and metal concentration in the muscle tissues of five commercially important fish species (Leiognathus equulus, Lates calcarifer, Sillago sihama, Scolopsis bimaculatus, Lutjanus fulviflamma) along Thondi coast, as well as the potential human health risks on consumption of these species were also studied. Water quality parameters, such as mean temperature (31.3 ± 1.86 °C), salinity (28.35 ± 0.79‰), pH (7.95 ± 0.22), TDS (12840 ± 1.49 mg L<sup>-1</sup>), TSS (310 ± 0.51 mg L<sup>-1</sup>) and DO (5.99 ± 0.14 mg L<sup>-1</sup>) were obtained. Various nutrients such as calcium (300.0 ± 36.05 mg L<sup>-1</sup>), inorganic phosphate (0.186 ± 0.02 μg L<sup>-1</sup>), magnesium (1077.6 ± 107.01 mg L<sup>-1</sup>), nitrate (1.584 ± 0.31 μg L<sup>-1</sup>), nitrite (1.179 ± 0.34 μg L<sup>-1</sup>), silicate (29.717 ± 1.93 μg L<sup>-1</sup>) and total phosphorus (0.153 ± 0.08 μg L<sup>-1</sup>) were also analysed. The concentration of metals As, Cd, Cr, Cu, Pb and Zn in the muscle tissue was determined using atomic absorption spectroscopy (AAS). Arsenic, Cu and Pb were found to be highest in S. sihama; 1.2364 ± 0.12, 1.6102 ± 0.28 and 1.0103 ± 0.21 μg/g respectively. Cadmium and Zn were found maximum in S. bimaculatus; 0.0876 ± 0.04 and 1.0564 ± 0.16 μg/g respectively, whereas Cr was found highest in L. Calcarifer; 1.6781 ± 0.18 μg/g. Compared our results with FAO/WHO/EU regulations. The estimated daily intake (EDI) specifies that there is no risk of consuming these species. However, the target hazard quotient (THQ) in As is found to be > 1 in these fish species, which implies a possible danger to consumers.

    Cellulose Chemistry and Technology, 2022
    The study shows a comparison of cellulose extracted from two species of red seaweeds, namely Hypnea musciformis and Sarconima filliformis. The celluloses were characterized by FTIR, XRD, TGA and SEM analyses. The studies show similarities in the characteristics of the celluloses extracted from H. musciformis and S. filliformis. FTIR analysis confirms the presence of O-H and C-H bonds in the celluloses of both species, while the XRD patterns of celluloses confirm their crystallinity, with a maximum peak at 22°. The thermal stability of the celluloses from H. musciformis and S. filliformis was observed in the range of 250 to 350 °C. The morphological structure of the celluloses was studied using SEM and both celluloses showed smooth pore-free surface.
  • Baseline study of trace metal concentrations in abandoned, lost or otherwise discarded fishing gear along Thondi coast, Palk Bay, India
    Nigariga Pasumpon, Sugumar Vasudevan
    Journal of Sea Research, 2022
    The Abandoned, Lost or otherwise Discarded Fishing Gear (ALDFG) are commonly found in the ocean these days due to the negligence of the fishermen. The present study aims to identify the discarded fishing gear sample and determine metals' absorption rate by ALDFGs. The identification of the ALDFG was done with the help of ATR-FTIR in which it was confirmed that the samples are mostly made of nylon 6. Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) peaks such as 3435.43 cm−1, 2926.38 cm −1, 2857.74 cm−1 correspond to nylon 6. Adsorption of trace metals by Inductively Coupled Plasma-Mass Spectroscopy (ICP-MS) confirmed the presence of elements such as Aluminium, Barium, Cadmium, Calcium, Chromium, Cobalt, Copper, Iron, Lead, Magnesium, Manganese, Nickel, Phosphorus, Potassium, Rubidium, Sodium, Strontium, Vanadium and Zinc in the identified plastic sample. The Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDX) micrographs were confirmed the adsorption of elements by the surface of the sample and revealed the level of adsorption of trace metals in the abandoned, lost or otherwise discarded fishing gear.
