    Abstract 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.

    Abstract The bioaccumulation of trace metals in 10 selected edible seaweeds was studied using inductively coupled plasma mass spectroscopy (ICP-MS). Bioaccumulation of higher levels of manganese (4.94 ± 0.15 μg/g) and aluminium (4.21 ± 0.18 μg/g) and lower levels of arsenic (0.18 ± 0.02 μg/g) and vanadium (0.09 ± 0.02 μg/g) were observed in Chlorophyta. In Rhodophyta, bioaccumulation of iron (8.51 ± 0.19 μg/g) was high, while lower levels of magnesium (0.13 ± 0.02 μg/g) and strontium (0.21 ± 0.01 μg/g) were observed among the seaweeds studied. Health assessment studies were also conducted on seaweeds to understand their effects on human consumption. The findings imply that consuming macroalgae has no health risk due to these elements in the general population. Furthermore, the confirmative toxicity of specific metals, such as Cd, Pb, and Zn metals in macroalgae, should be monitored constantly.

    Abstract The present study deals with the bioaccumulation of heavy metals in different seagrass species (Syringodium isoetifolium, Halodule pinifolia, Cymodocea serrulata, Halophila ovalis) along Thondi coast and decaying seagrass offshore. Heavy metal concentrations in the seagrass samples were analysed during the period of April 2019 to March 2020 using atomic absorption spectrophotometry. Among the heavy metals assayed, the level of manganese was higher (15.62 ± 1.02 mg/kg) and chromium was the least metal observed (0.002 mg/kg). One-way ANOVA revealed significantly higher level of heavy metals in summer season, while it gradually decreased through pre-monsoon to monsoon season (P < 0.05). Cadmium and chromium were observed to be below detectable levels in the seagrass species. S. isoetifolium was found to bioaccumulate higher levels of heavy metals than the other seagrass species studied. Elucidation of heavy metal levels in the dead and decayed seagrass offshore revealed a higher level of heavy metals than live seagrass species.

    Abstract 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

    Abstract This study aimed to monitor the concentrations of metals including Cd, Pb, Cu and Zn in commercially important and commonly edible brown, red and green algal species collected from Thondi coast, southeast India. Green seaweed Chaetomorpha linum contained higher (Cd 8.51 mg kg−1, Pb 5.24 mg kg−1, Cu 15.38 mg kg−1, and Zn 22.34 mg kg−1) concentrations of metals than other tested seaweed samples. The concentrations of metals significantly varied within and between the investigated species of seaweed samples (P < 0.05). It was revealed that Cd, Pb, Cu and Zn metals were present in the species of seaweeds at different concentration. The residual levels of metals were less than the maximum allowable levels specified for human consumption compared to PTWIs, JECFA, FAO/WHO, FSSAI and EC. This study suggested that exposure to the analysed metals (Cd, Pb, Cu and Zn) through seaweeds consumption does not raise serious health effects to consumers and it is safe for human consumption.
