摘要

为了解玛瑙染色对周边农田的影响，在玛瑙染色村周边农田采集土壤样品118份。分析了这些样品的金属浓度和镉、汞、砷、铅、铬、铜、镍和锌的土壤污染。此外，还进行了生态风险评估，同时评估了居民通过口服摄入、吸入和皮肤接触的健康风险。内梅罗复合指数结果显示，8种重金属均超过警戒线。村子周围地区存在高浓度的镍，可能是由于玛瑙污渍中存在金属镍。风险评价结果表明，研究区潜在生态风险等级为中低。然而，儿童和成人的总致癌风险都超过了10-6的可接受阈值，表明风险不可接受。另一方面，总的非致癌性危害系数在可接受范围内。口服摄入是暴露的主要途径。

Characterization and Risk Assessment of Heavy Metals in Topsoil of Agricultural Land from an Agate Dyeing Village

To investigate the impact of agate dyeing on the surrounding farmland, a total of 118 soil samples were collected from farmland surrounding an agate dyeing village. These samples were analyzed for metal concentrations and soil contamination of Cd, Hg, As, Pb, Cr, Cu, Ni, and Zn. Additionally, an ecological risk assessment was conducted along with an assessment of health risks for residents through oral ingestion, inhalation, and dermal contact. The results of the Nemerow complex indices showed that the eight heavy metals exceeded the warning line. High concentrations of Ni were present in areas around village, likely due to the presence of metallic Ni in the agate stain. The risk assessment revealed that the potential ecological risk in the study area was classified as low to medium. However, the total carcinogenic risk for both children and adults exceeded the acceptable threshold of 10^–6, indicating an unacceptable risk. On the other hand, the total non-carcinogenic hazard quotients were within acceptable limits. Oral ingestion was the primary pathway of exposure.

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
