However, health risks associated with these spaces in China remain insufficiently characterized. This study systematically collected 90 soil samples from park and roadside green spaces across five districts of Nanchang, utilizing X-ray fluorescence spectrometry for quantitative analysis of major heavy metal contaminants. The results indicated elevated concentrations of Pb, Zn, and Cr in Donghu District soils, although all single-factor pollution indices (Pi) remained below 1.00. Comprehensive pollution assessment classified contamination levels as either mild (1.00 < P<sub>N</sub> ≤ 2.00) or moderate (2.00 < P<sub>N</sub> ≤ 3.00), with ecological risk indices (RI) consistently below 30, signifying low ecological hazards. Exposure pathway analysis identified oral ingestion as the primary route of heavy metal intake for Nanchang residents, followed by dermal contact and inhalation. Children exhibited higher potential non-carcinogenic risks compared to adults, with Cd specifically posing oral exposure risks to pediatric populations. Cumulative carcinogenic risk assessments for Cr, Ni, As, Cd, and Pb yielded values of 1.57 × 10<sup>-6</sup> and 1.23 × 10<sup>-6</sup> respectively, slightly exceeding the 10<sup>-6</sup> safety threshold yet remaining within low-risk parameters.

In conclusion, this study offers preliminary evidence suggesting that exposure to trace metals particularly Cd and As may potentially be associated with prostate cancer.

The purpose of this study was examining the degree of groundwater contamination in Delhi, India, particularly regarding the effects of mining operations in the Aravalli Hills. This study uses an integrated approach that includes the water quality index (WQI), modified heavy metal pollution index, human health risk assessment (HHRA), and geospatial techniques to evaluate the effects of mining on groundwater quality. Data of various physiochemical parameters and heavy metals were collected from the Central Groundwater Board for the year 2023-24. The WQI was calculated by using a hybrid aggregation technique and human health risk was assessed due to the ingestion and dermal contact by using the United States Environmental Protection Agency model. The WQI of the Delhi varies from 2.15 to 94.03. Results of WQI concluded that the groundwater quality of Delhi state was mostly lie in the category of poor to very poor quality, indicating serious deterioration. According to the results of HHRA, the value of total hazard index (THI) was varying from 0.86 to 49.25 for infants, 0.39 to 33.62 for children, 0.18 to 15.71 for teens and 0.16 to 13.72 for adults. The spatial distribution of WQI, THI and cancer risk were further mapped using geospatial mapping techniques, which also connected them to certain mining zones and geological vulnerabilities. In order to reduce contamination and safeguard public health, finding of the study highlights the urgent need for groundwater management plans, sustainable mining methods, and regulatory actions. In order to encourage water conservation measures and lower the release of pollutants into the environment, public awareness campaigns and community involvement should also be crucial.

To investigate the remediation efficiency and explore the application potential of intercropping patterns featuring hyperaccumulator Pteris vittata in orchards, this study focused on peach trees, a major economic fruit crop, and conducted a systematic examination of intercropping in As-contaminated orchard soil. First, the screening pot experiment compared the As accumulation ability of 10 main peach cultivars in local areas. The results showed that the As content in the peach roots was the highest, followed by the leaves and stems. Lvhua 9 (LH9) and Ruipan 13 (RP13) peach trees had better growth and lower As accumulation. Second, a pot intercropping experiment of P. vittata and low-As peach cultivars (LH9 and RP13) was conducted by the rhizosphere bag method (monoculture, restricted intercropping, opening intercropping). Compared with monoculture, intercropping increased the As content in P. vittata (8.29-134%) and decreased the As content in peach (31.1-69.1%) by root interaction. In addition, intercropping significantly increased the abundance of As-resistant Sphingomonas in the rhizospheres of the two peach cultivars and P. vittata (21.4% to 108%), and the As removal rate was increased (up to 198%). Finally, in the field experiment, the intercropping of P. vittata and LH9 significantly promoted the growth, photosynthesis, and As uptake of P. vittata, especially in rainy July and August. Moreover, the yield of peach fruits was not notably affected, and their As content met national standards. In conclusion, intercropping P. vittata with selected peach cultivars in As-contaminated orchard soils effectively enhances As remediation efficiency while maintaining fruit quality and safety, demonstrating its promising application potential for sustainable orchard management.</p>","PeriodicalId":11759,"journal":{"name":"Environmental Geochemistry and Health","volume":"47 6","pages":"187"},"PeriodicalIF":3.2,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143985194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
