Heavy metal contamination and its impact on the food chain: exposure, bioaccumulation, and risk assessment

CyTA - Journal of Food, Journal Year: 2025, Volume and Issue: 23(1)

Published: Jan. 2, 2025

Non-essential heavy metals (HMs) are one of the most toxic substances released into environment, affecting food chain and posing a threat to security. The research data was collated after carefully observing some studies conducted on commonly consumed products highlighting metal exposure pathways crops techniques adapted quantification HMs in chain. tools developed estimate ecological health risks induced via ingestion HM-contaminated both children adults India discussed. It is observed that Cd, Cr, Cu, Pb, Zn studied products. Bioaccumulation indices Indian revealed varying intake. Children suffer more from consuming contaminated with than adults. This review summarizes distribution HMs, their pollution, correlation between each HM concentration.

Pesticides and heavy metal toxicity in fish and possible remediation – a review

Annals of Animal Science, Journal Year: 2024, Volume and Issue: 24(4), P. 1007 - 1024

Published: Jan. 24, 2024

Abstract Pesticides and heavy metals are considered as potent contaminants in aquatic environment. Both sourced into the ecosystems by various types of anthropogenic well natural practices. Such contamination drastically affect normal activity associated living organisms particularly fish. pesticides toxicity cause several negative effects on fish growth, physiology, immune response, reproduction, embryonic larval development different histopathology major organs including gill, kidney, liver, gonads, intestine. Besides, consumption contaminated poses a serious health concern to consumers. Considering these issues, current review is designed investigate toxic aspects fishes along with their possible sources, types, mode action role medicinal herbs mitigate toxicity.

Environmental Pollutants as Emerging Concerns for Cardiac Diseases: A Review on Their Impacts on Cardiac Health

Biomedicines, Journal Year: 2025, Volume and Issue: 13(1), P. 241 - 241

Published: Jan. 20, 2025

Comorbidities related to cardiovascular disease (CVD) and environmental pollution have emerged as serious concerns. The exposome concept underscores the cumulative impact of factors, including climate change, air pollution, chemicals like PFAS, heavy metals, on health. Chronic exposure these pollutants contributes inflammation, oxidative stress, endothelial dysfunction, further exacerbating global burden CVDs. Specifically, carbon monoxide (CO), ozone, particulate matter (PM2.5), nitrogen dioxide (NO2), sulfur (SO2), pesticides, micro- nanoplastics been implicated in morbidity mortality through various mechanisms. PM2.5 leads inflammation metabolic disruptions. Ozone CO induce stress vascular dysfunction. NO2 cardiac remodeling acute events, metals exacerbate cellular damage. Pesticides microplastics pose emerging risks linked tissue Monitoring risk assessment play a crucial role identifying vulnerable populations assessing pollutant impacts, considering factors age, gender, socioeconomic status, lifestyle disorders. This review explores disease, discussing risk-assessment methods, intervention strategies, challenges clinicians face addressing pollutant-induced diseases. It calls for stronger regulatory policies, public health interventions, green urban planning.

Sensitivity ecology and evolution, toxicology organism assessment model in the use of chemical applications for the management of toxic substances

Deleted Journal, Journal Year: 2024, Volume and Issue: 44(5), P. 890 - 908

Published: June 22, 2024

The sensitivity of organisms to toxic substances is a pivotal facet in ecological and toxicological research. Understanding differential sensitivity's basis its evolutionary underpinnings imperative for anticipating managing the repercussions toxins on organisms. Our comprehensive analysis reveals that physiological traits, encompassing metabolic capacity, membrane transporters, wield significant influence determining organism toxins. Evolutionary processes, including natural selection genetic variations also contribute tolerance or resistance substances. This review focuses existing research concerning sensitivity, particularly emphasizing toxicokinetics, toxicodynamics, factors underlie Furthermore, it explores practical applications predictive ecotoxicology chemical management identifies promising prospects models. integration these insights into development application can usher era effective environmentally benign chemicals, thereby curtailing impacts fostering harmonious coexistence between their surroundings.

Non-Lethal Assessment of Land Use Change Effects in Water and Soil of Algerian Riparian Areas along the Medjerda River through the Biosentinel Bufo spinosus Daudin

Water, Journal Year: 2024, Volume and Issue: 16(4), P. 538 - 538

Published: Feb. 9, 2024

The land use change can negatively impact ecosystems, enriching water and soil with heavy metals (HMs). fragile riparian areas along the Medjerda River of Northern Algeria are particularly affected by this phenomenon, biological tools able to combine information about both matrices be preferred in their monitoring. This research aimed evaluate suitability spiny toad (Bufo spinosus D.) as a biomonitor for assessing three different uses (agricultural (AGR), urban (URB), industrial (IND) managements) on Cu, Fe, Pb, Zn using non-lethal skin biopsy. IND use, followed URB, mostly impacted soils Cu whereas management was not influence differently despite worrying Pb levels. cluster analysis allows show that responds like terms HMs, it is possibly related metal–chemical affinity. Although single analyses do display any difference among managements, bioaccumulation factor (BF > 1) shows B. absorbs more HMs from water; accumulates Fe regardless probably natural anthropogenic assimilation URB IND, ionic forms human impact.

Published: Nov. 30, 2023

The presence of trace metals in aquatic ecosystems can have detrimental effects on fish survival. Tanguar haor, a Ramsar conservation wetland, receives sediment and water from multiple transboundary rivers. However, there been limited studies the metal concentrations species this sediment-rich wetland. This study aimed to analyze iron (Fe), manganese (Mn), chromium (Cr), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb) water, sediment, tissues. Higher Cd Pb were found sediment. All these detected eight species, including benthic pelagic species. Among them, Systomus sarana, that also consumes organisms, exhibited higher pollution index than other fish, particularly release into has potential impact accumulation fish. SYNOPSIS: will aid policymaking ecotoxicology research for river-connected wetlands.
