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

CyTA - Journal of Food, Год журнала: 2025, Номер 23(1)

Опубликована: Янв. 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.

Assessment of Toxicity, Health Risks, and Environmental Impact of Trace Metals in River Sediments of the Middle Black Sea Region (Samsun, Turkey): Bioaccumulation Potential in the Freshwater Amphipod Hyallella azteca

The present work studied the sources, concentrations, distributions, and possible ecotoxicological risks of trace metals (TMs) in surface sediments Kızılırmak Yeşilırmak Rivers, largest rivers Black Sea Region Türkiye, Mert Engiz Rivers located between these rivers, to evaluate region’s health pollution status. Average TM concentrations were measured mg/kg ordered from smallest as Cd (4.1) < Co (19.9) Ni (31.6) Cu (34.9) Pb (37.8) Cr (197.6) Zn (213.9) Al (24408.8) Fe (35920). Seasonal changes observed, especially during dry season, Pb, Zn, found increase. Environmental risk assessment indices (EF, CF, I_geo, PLI) indicated medium high contamination levels potential ecological impacts. Likewise, while TRI ATI among toxicity showed toxic levels, highest individual growth rate (IGR) results Hyallella azteca used bioavailable observed control sediment (6.8). However, whereas survival was 100% sediment, it did not fall below 70% at other sampling points. Bioaccumulation factor (BAF) that Cu, Cd, Co, accumulated H. tissues. Health no for adults demonstrating a slight children. Statistical analyses (PCC PCA) presence anthropogenic, lithogenic sources effects industrial agrogenic sources.

A perspective on heavy metal(loid)s traceability in soil surrounding coal gangue areas: combined application of multiple source analysis methods

Frontiers in Environmental Science, Год журнала: 2025, Номер 13

Опубликована: Апрель 30, 2025

In China, coal remains the dominant energy source, leading to substantial production of gangue. This study established comparative zones—a area and a control area—and applied Geo-Detector model (GDM), Absolute Principal Component Score-Multiple Linear Regression (APCS-MLR) model, cadmium isotope fingerprinting delineate origins heavy metal(loid)s (HMs) in soil proximate accumulations The contents (Cd), mercury (Hg), arsenic (As), lead (Pb) were significantly elevated relative control, whereas levels chromium (Cr), copper (Cu), nickel (Ni), zinc (Zn) displayed no marked differences between zones, underscoring an intensified pollution level region. integration GDM, APCS-MLR, Cd methods enhanced precision dependability identifying sources. Soil contamination was predominantly due persistent gangue accumulation, vehicular emissions, agricultural chemicals, contributing 40.1%, 33.7%, 26.2% respectively, while area, emissions activities main contributors. Surface runoff from accumulation emerged as pathway for area. underscores urgency implementing strategic management mitigation ecological hazards, particularly those associated with levels.
