| 摘要 | Guigang City of Guangxi, located in the Xunyu Plain, has abundant selenium-enriched soil resources as the core foundation for the development of selenium-enriched industries in the region. However, the coexistence of heavy metals in some of its selenium-enriched soils has become the main bottleneck problem restricting the sustainable and high-quality development of selenium-enriched industries in the region. Based on field sampling data from a 1∶50 000 soil geochemical survey in the five districts of Guigang City, combined with the results of heavy metal pollution detection in crop samples, the analysis on characteristics of heavy metal content in crops and the industrial impact is carried out, and the situation of heavy metal exceeding the standard in agricultural product samples in the five districts is identified. The multiple threats of heavy metals to the quality and safety of selenium-enriched agricultural products, industrial brand image, market competitiveness, and sustainable utilization of selenium-enriched soil resources are revealed. A comprehensive prevention and control system needs to be constructed from the dimensions of source prevention and control, soil remediation, variety screening, and standard control, to ensure the green, safe, and high-quality development of selenium-enriched industry. |
