A meta-analysis and experimental survey of heavy metals pollution in agricultural soils

Journal of Trace Elements and Minerals, Journal Year: 2024, Volume and Issue: 9, P. 100180 - 100180

Published: June 18, 2024

Heavy metal (HM) pollution in agricultural soils represents a hidden danger to food security worldwide. In this paper, the spatio-temporal trends of heavy metals from eight countries and 50 soil samples farmland were evaluated through combination field surveys meta-analysis provide comprehensive report on pollution. The analysed using inductively coupled plasma–mass spectrometry (ICP-MS) (Perkin Elmer Nixon 300Q). contamination factor (CF) load index (PLI) calculated. results CF indicate extreme for Cr, suggesting ecotoxicological effects, while PLI values range baseline moderate Cd, Hg, Cu, Zn, Ni, except which shows very high pollution, that oils have undergone some form deterioration. reviewed articles published between 2010 2023 showed increasing all HMs. weighted mean As, Ni 0.0-222.7, 0.08-289.2, 0.03-193, 2.94-198.1, 0.0-771.1, 0.0-231, 1.71-99.75.6 mg/kg, respectively. Zn As exceeded two three times China National Environmental Monitoring Centre (CNEMC) European Union's most cited guideline (MEF), rock crust guideline. correlation matrix heatmap revealed highly positive Cr (R2 = 0.66), these elements same source are likely prevalent soils. spatial origin publications reveals 82% studies followed by South Africa Italy accounting 4% respectively Nigeria, Egypt, Morocco, Iran, Turkey account 2% each. findings study important implications environmental regulation protection Unlike previous often adopt "silos" method, highlights nexus approach integrates both experimental could establish more understanding

Socioeconomic and environmental determinants of asthma prevalence: a cross-sectional study at the U.S. County level using geographically weighted random forests

International Journal of Health Geographics, Journal Year: 2023, Volume and Issue: 22(1)

Published: Aug. 10, 2023

Abstract Background Some studies have established associations between the prevalence of new-onset asthma and exacerbation socioeconomic environmental determinants. However, research remains limited concerning shape these associations, importance risk factors, how factors vary geographically. Objective We aimed (1) to examine ecological multiple socio-physical determinants in United States; (2) assess geographic variations their relative importance. Methods Our study design is cross sectional based on county-level data for 2020 across States. obtained self-reported adults aged 18 years or older each county. applied conventional geographically weighted random forest (GWRF) investigate (e.g., poverty) air pollution green space). To enhance interpretability GWRF, we assessed through partial dependence plots, ranked according global scores, (3) mapped local variable spatially. Results Of 3059 counties, average was 9.9 (standard deviation ± 0.99). The GWRF outperformed forest. found an indication, example, that temperature inversely associated with prevalence, while poverty showed positive associations. plots had a non-linear shape. Ranking smoking depression were most relevant, space language minor relevance. measures striking geographical differences. Conclusion findings strengthen evidence environments play role explaining but relevance seems results are vital implementing future prevention programs should be tailor-made specific areas.

Human health risks of heavy metal(loid)s mediated through crop ingestion in a coal mining area in Eastern China

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 276, P. 116305 - 116305

Published: April 9, 2024

The heavy metal(loid)s (HMs) in soils can be accumulated by crops grown, which is accompanied crop ingestion into the human body and then causes harm to health. Hence, health risks posed HMs three for different populations were assessed using Health risk assessment (HRA) model coupled with Monte Carlo simulation. Results revealed that Zn had highest concentration among crops; while Ni was main polluting element maize soybean, As rice. Non-carcinogenic all through rice at an "unacceptable" level, teenagers suffered higher than adults children. All of might suffer Carcinogenic risk, similar order Total carcinogenic (TCR): TCRAdults > TCRTeenagers TCRChildren. identified as priority control this study area due their high contribution rates risks. According HRA results, associated varieties, HM species, age groups. Our findings suggest only limiting Maximum allowable intake rate not sufficient prevent caused HMs, thus more precautions are needed.

Soil pollution and elemental sources along Barapukuria coal mine, Bangladesh: Implications for eco-environmental and health risk assessment

Heliyon, Journal Year: 2024, Volume and Issue: 10(12), P. e32620 - e32620

Published: June 1, 2024

For the first time, different pollution indices and a receptor model have been used to quantify eco-environmental health risk assessments as well identify sources of potentially toxic elements in soil along Barapukuria Coal Mine (BCM). Individual include enrichment contamination factors showing samples are moderately highly contaminated by arsenic, cobalt, chromium, copper, lead, zinc heavily sulfur. According geo-accumulation index, there is significant with arsenic (1.24 ± 0.38), lead (1.49 0.58), cobalt sulfur (1.63 0.38). Modified hazard quotient ecological factor values also suggest low moderate environmental hazards from same elements. The nemerow load index range 1.65 3.03, 0.82-1.23, 11-26, 77-165, 6.82-11.76 pollution, among other synergistic indices. Health assessment indicates that iron poses lower cancer for children than adults, while both face unacceptable risks inhaling or arsenic. Principal component phylogenetic cluster analysis extracted multiple linear regression absolute principal score (APCS-MLR) refer fact manganese, iron, titanium, nickel originated geogenic sources, coal mine effluents enrich like zinc, uranium, sulfur, thorium, phosphorous sourced agriculture. In addition, anthropogenic including agriculture activities, could pollute ecosystem. findings crucial regional national planners devising strategies mitigate element areas.
