Marine pollution caused by heavy metals has emerged as a significant environmental concern, garnering increased attention in recent years. The accumulation of the tissues marine organisms poses substantial threats to both ecosystems and human populations that rely on seafood primary food source. Fish crustaceans are effective biomonitors for assessing metal contamination aquatic environments. In this study, we determined concentrations several metals, including cadmium (Cd), lead (Pb), nickel (Ni), mercury (Hg), tin (Sn), four fish species (Mugil cephalus, Mugil capito, L. aurata, Morone labrax) five crustacean (S. rivulatus, Cerastoderma glaucum, Paratapes undulatus, R. decussatus, Callinectes sapidus, Metapenaeus Stebbingi) from Temsah Lake during winter summer seasons. To evaluate potential ecological health risks associated with consuming these species, calculated index (MPI), weekly intake (EWI), target hazard quotient (THQ), carcinogenic risk (CR) values. results revealed noticeable increase levels compared studied samples. Moreover, concentration muscles generally exceeded those liver gills. MPI values indicated labrax exhibited highest winter, while aurata showed summer. cephalus demonstrated lowest EWI were found be lower than corresponding tolerable (TWI) Additionally, under average exposure conditions, THQ HI data below one most study area. CR investigated acceptable levels. Therefore, suggests within lake does not present any hazards consumers.

Опубликована: Окт. 20, 2024

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.

Bioaccumulation and Trophic Transfer of Heavy Metals in Marine Fish: Ecological and Ecosystem-Level Impacts

Journal of Xenobiotics, Год журнала: 2025, Номер 15(2), С. 59 - 59

Опубликована: Апрель 18, 2025

Heavy metal contamination in marine ecosystems poses a critical environmental challenge, with significant implications for biodiversity, trophic dynamics, and human health. Marine fish are key bioindicators of heavy pollution because their role food webs capacity bioaccumulation transfer. This review synthesizes current knowledge on the pathways mechanisms accumulation fish, focusing factors that influence uptake, retention, tissue distribution. We explore processes governing transfer biomagnification, highlighting species-specific patterns risks posed to apex predators, including humans. Additionally, we assess ecological consequences at population, community, ecosystem levels, emphasizing its effects reproduction, community structure, interactions. By integrating recent findings, this highlights gaps suggests future research directions improve monitoring risk assessment. Given persistence bioavailability metals environments, effective control strategies sustainable fisheries management imperative mitigate long-term public health risks.

Human exposure to heavy metals and possible public health risks via consumption of mussels M. galloprovincialis from the Albanian sea cost

Chemosphere, Год журнала: 2024, Номер 368, С. 143689 - 143689

Опубликована: Ноя. 1, 2024

Heavy metals in the marine environment are significant contaminants that readily bioaccumulate tissues of aquatic organisms, particularly filter-feeding animals such as bivalve molluscs. Human exposure to elevated concentrations heavy metals, including essential elements Fe, Cu, and Zn, through consumption seafood can lead various pathological effects. Research has demonstrated among molluscs, mussels most effective indicators for monitoring pollution. Consequently, this study focused on species Mytilus galloprovincialis evaluate levels Al, As, Cd, Cr, Mg, Ni, Pb, Zn two primary harvesting areas Albania assess associated human health risks from mussel consumption. The results revealed a concerning situation, Pb with average 2.15 μg/g 4.14 μg/g, respectively, significantly exceeding limits established by Regulation (EC) No. 915/2023. other investigated also raised concerns, only half them were within dietary intake values recommended scientific authorities weekly 250 g mussels.

Is the concentration of heavy metals in sun-dried Engraulicypris sardella (Günther, 1868) in Malawi, a human health risk?

Environmental Chemistry and Ecotoxicology, Год журнала: 2024, Номер 6, С. 354 - 362

Опубликована: Янв. 1, 2024

The effects of trophic cascades have made small-size pelagic fish species, such as Engraulicypris sardella, from Lake Malawi an important ecological and food system. However, human-induced activities can potentially pollute exposing E. sardella to heavy metals contamination. This could pose a system health risk the population Malawians neighboring countries, which heavily rely on source animal protein. Therefore, this study investigated concentration levels Lead (Pb), Cadmium (Cd), Zinc (Zn), Copper (Cu), Manganese (Mn), Iron (Fe) in sun-dried conducted assessment associated with its consumption. samples were collected Karonga, Nkhata Bay, Nkhotakota, Salima, Mangochi districts between December 2023 February 2024. results revealed significant variations Cd, Zn, Cu, Mn, Fe concentrations among sampled sites while Pb contamination was not detected. within acceptable consumption limits set by Food Agriculture Organization (FAO) World Health (WHO) 2012. fish's average Cd (0.17 mg kg−1 ww) slightly above recommended threshold 0.1 ww FAO/WHO (2012) but remained below limit 0.5 FAO 1983. Furthermore, none analyzed posed effect people. there is need for regular monitoring metal other mostly consumed species Malawi, both fresh processed, sustained guarantee safety consumers.
