Enrichment, contamination, ecological and health risks of toxic metals in agricultural soils of an industrial city, northwestern China

Journal of Trace Elements and Minerals, Journal Year: 2022, Volume and Issue: 3, P. 100043 - 100043

Published: Dec. 19, 2022

The impacts of rapid urbanization and industrialization often cause toxic metal contamination in agricultural soils, which has been a global environmental issue. Agricultural soil samples were obtained from Lanzhou city, typical industrial city northwestern China. levels six metals (i.e., Cd, Cr, Cu, Pb, Sb, Zn) determined using Inductively Coupled Plasma Optical Emission Spectrometer. Afterwards, enrichment, contamination, ecological health risks them comprehensively evaluated. average concentrations 0.30, 79.7, 21.6, 26.7, 0.97, 69.0 mg kg−1 for Zn, respectively soils. Cd was moderately enrichment while other minimally enriched soils Lanzhou. characterized by moderate to considerable low metals. Moreover, might noticeable at most sites. In addition, the target hazard quotient (THQ) children 0.727, almost ten times higher than that adults. Sb sensitive factors affecting risk assessment contributed over 99% THQ. Lithogenic source, mining activities, phosphorus fertilizer usage three main Zn Lanzhou, should be taken into consideration future supervision management. Health these metals, especially receive attention due their hazard.

Contamination source, health and ecological risk assessment of hazardous elements in the sediment of the Shahid Rajaee reservoir

Frontiers in Environmental Science, Journal Year: 2024, Volume and Issue: 12

Published: Oct. 21, 2024

Sediment pollution from potentially hazardous elements (PHE) generated by human activity has grown into a worldwide problem. In this regard, for the first time, surface sediment samples were obtained six points along Shahid Rajaee Reservoir investigation. Elements concentrations (Cu, Cr, Co, Mn, Fe, Pb, Ni, and Zn) assessed using ICP-MS. Based on individual indices (geoaccumulation index, contamination factor), all at sample sites found to be low in contamination, except Pb Zn (at 1 2). The combined effect of PHEs did not show considerable concern, according synergistic indices. health risk assessment revealed that recreational receptors unlikely face non-carcinogenic or carcinogenic hazards as consequence exposure sediments with unintentional ingesting contact skin. Tessier technique demonstrated mostly connected oxidizable fraction. According statistical study, while Cu, Mn lithogenic sources, came natural well human-made sources.

Assessment of human health hazard associated with heavy metal accumulation in popular freshwater, coastal and marine fishes from south-west region, Bangladesh

Heliyon, Journal Year: 2023, Volume and Issue: 9(10), P. e20514 - e20514

Published: Sept. 29, 2023

An analysis was conducted on both freshwater, coastal and marine fish species to evaluate the concentrations of heavy metals, with aim assessing their levels examining potential health risks for humans linked consumption contaminated fish. This study estimate Cr, Fe, Cu, As, Cd Pb in 60 individuals belonging 20 (10 freshwater another 10 fishes) by using Atomic Absorption Spectrophotometer. Metal fishes were exceeded maximum allowable concentration (MAC). The Estimated Daily Intake (EDI), Average Pollution Load Index (APLI), Target Hazard Quotient (THQ), (HI) Cancer Risk (TCR) metals determined assessment human risk. Ranking order values EDI fishes, > Fe Cr Cu As Cu. Highest APLI value 8.14 (Puntius ticto) that is seriously polluted 3.003 observed Otolichthoides pama respectively. THQPb THQAs all exceed safe limit (THQ>1) suggesting risk consumers. hazard index samples USEPA (United States Environmental Protection Agency) permitted level (HI 1). target carcinogenic crossed standard (TCR> 1E-04), which denotes continuous studied may cause On other hand, sensitivity indicates metal responsible factor
