The bioaccumulation of trace elements and heavy metals in aquatic organisms is a critical environmental concern due to its potential impact on ecosystem health human safety. This study investigated the level Labeo rohita Mystus seenghala from River Jhelum district Khushab, Punjab, Pakistan. concentration calcium, magnesium, iron, nickel, copper, arsenic, cadmium, zinc, chromium, manganese, cobalt, lead gills, liver, muscle tissues these fish was measured using inductively coupled plasma-mass spectrometry. Then, extent contamination possible risks were assayed. Our findings indicate significant variations elemental metal concentrations among different organs between species, reflecting their diverse feeding habits habitats. risk assessment based estimated daily intake, weekly maximum permissible target hazard quotient, index or total index, cancer revealed consumers fish. emphasizes need for continuous monitoring, as new data insights are crucial understanding mitigating risks. Strict regulatory measures also necessary safeguard public preserve River.

Elevated Trace Element Concentrations in Arabian Scallops, Natal Rock Oysters, and Intermediate Clams in the Persian Gulf

Journal of Trace Elements in Medicine and Biology, Journal Year: 2025, Volume and Issue: 89, P. 127659 - 127659

Published: April 23, 2025

This study aimed to quantify trace element concentrations in Arabian scallops (Mimachlamys sanguinea), Natal rock oysters (Saccostrea cucullata), and Intermediate clams (Tivela damaoides). These elements accumulate over time from water, food, sediment, potentially leading toxicity. Specimens were collected coastal waters around Larak Island, processed, analyzed for including copper (Cu), iron (Fe), cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg), zinc (Zn), vanadium (V), magnesium (Mg), manganese (Mn), selenium (Se), nickel (Ni), cobalt (Co). The samples ashed, digested, then using inductively coupled plasma mass spectrometry (ICP-MS). findings revealed that Fe levels highest T. damaoides, significantly exceeding those M. sanguinea (p < 0.05). Cd higher compared S. cucullata damaoides Zn, Mn, Ni, Pb, V, Co, Hg, Cu, As, Se showed no significant interspecies differences > However, variations noted Mg with showing the markedly more than observed Comparison WHO/FAO standards Pb soft tissues of all three bivalve species exceeded permissible limits, though other metals within safe consumption levels. bivalves safety indicating a potential health risk. emphasize necessity monitoring contamination ensure seafood protect public health.

Bioaccumulation Patterns of Trace Elements in Jellyfish (Crambionella orsini and Cassiopea andromeda) from Northwestern Coastal Waters of the Persian Gulf

Journal of Marine Science and Engineering, Journal Year: 2024, Volume and Issue: 12(11), P. 1938 - 1938

Published: Oct. 29, 2024

Trace element pollution in the Persian Gulf originates from industrial activities, urbanization, shipping, and oil extraction, leading to accumulation sediments, water, marine life such as jellyfish. This study investigated trace bioaccumulation two jellyfish species, Crambionella orsini Cassiopea andromeda, across different locations. Jellyfish samples were collected Mahshahr Dilam ports, their concentrations analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The revealed no significant differences between C. andromeda. However, levels of copper, iron, manganese, nickel significantly higher specimens compared those Dilam. No observed for cadmium, mercury, vanadium, tin, magnesium, selenium sites. Lower lead, arsenic, zinc, cobalt found Mahshahr. Additionally, correlation water bodies. These findings offer valuable insights into distribution elements populations environments Gulf.

Lead Nitrate (Pb(NO₃)₂) Toxicity Effects on DNA Structure and Histopathological Damage in Gills of Common Carp (Cyprinus carpio)

Microscopy Research and Technique, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 23, 2024

ABSTRACT The toxic impact of environmentally relevant nominal sub‐lethal concentration lead nitrate (23 mg/L) on the gills Cyprinus carpio after 30 days exposure was assessed. Structural alterations were analyzed through histopathology, and DNA damage rate in peripheral erythrocytes evaluated by alkaline comet assay. A significant deviation gill histoarchitecture observed compared to control group. Significant changes, including curling secondary lamellae, loss filaments, necrosis, hyperplasia, hypertrophy cells primary filament, vacuolization, found fish exposed nitrate. Moreover, assay showed nitrate‐induced damage, evidenced length “tail” fish. findings this study strongly indicated that nitrate, even at levels, could significantly alter overall physiology This situation severe ecological consequences.
