Abstract

Exposure to fluorine (F) in soil increases the risks of dental and skeletal fluorosis and osteoporosis. Therefore, it is important to accurately determine the soil F concentration, and quantitatively evaluate the factors that affect the human health risk of soil F. Differences in soil F concentrations were investigated based on source type (anthropogenically contaminated or naturally enriched) and determination method (perchloric acid extraction-distillation (PAED) or alkali fusion-filtration). A soil sample without contamination history (background F concentration = 208 mg·kg⁻¹) was collected and injected with sodium fluoride (NaF) to prepare anthropogenically F-contaminated soil. Mica gravel (> 2 mm) was ground and mixed with quartz powder to mimic soil components of natural F origin. The F concentration in anthropogenically contaminated soil did not significantly differ between methods (slope = 0.959, p > 0.05). The concentration in the naturally F-enriched soil analyzed using alkali fusion-filtration was approximately twice that of the sample analyzed using PAED (slope = 0.548, p < 0.05). This significant difference was ascribed to the abundance of chemically stable F. Non-carcinogenic hazard quotients for children differed between methods in naturally F-enriched soil, at 1.335 (alkali fusion-filtration) and 0.641 (PAED). These findings offer valuable insights for assessing, managing, and remediating soils contaminated or enriched with F.

产地对土壤中氟的化学萃取性的影响及其对人类健康风险的影响

接触土壤中的氟（F）会增加罹患氟斑牙、氟骨症和骨质疏松症的风险。因此，准确测定土壤中氟的浓度并定量评估影响土壤氟对人体健康风险的因素非常重要。研究人员根据来源类型（人为污染或天然富集）和测定方法（高氯酸萃取-蒸馏（PAED）或碱熔-过滤）调查了土壤中氟浓度的差异。采集无污染历史的土壤样本（本底 F 浓度 = 208 mg-kg-1）并注入氟化钠 (NaF)，制备人为 F 污染土壤。云母砾石（> 2 毫米）经研磨后与石英粉混合，以模拟天然氟来源的土壤成分。人为污染土壤中的 F 浓度在不同方法之间没有显著差异（斜率 = 0.959，p > 0.05）。采用碱熔过滤法分析的天然富钙质土壤中的钙浓度约为采用 PAED 分析的样本的两倍（斜率 = 0.548，p <0.05）。在富含膳食纤维的天然土壤中，不同方法得出的儿童非致癌危害商数也不同，分别为 1.335（碱熔过滤法）和 0.641（PAED）。这些发现为评估、管理和修复受 F 污染或富集的土壤提供了宝贵的见解。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
