Pakchoi (Brassica rapa subsp. Chinensis) is widely grown in Vietnam and many other Southeast Asian countries. Brassica rapa has long been known for its ability to accumulate many types of metals. Along with the metal functional type in the soil, the main source of the metal functional type of Brassica rapa, the metal composition becomes a key to support the determination of the geographical origin of the plant. Our study has built an analytical model and predicted the geographical location of the Brassica rapa growing area based on the metal composition in the soil of the crop. Twenty-seven metals in the soil of 9 regular cultivation sites serving the Hanoi market from September 2021 to May 2024 were determined by ICP-MS, and then the data were analyzed and a predictive model was built using the LDA analysis method. The results of this study provide a target origin model for improvement, as well as a way to identify the origin of other vegetable crops in the food market in Northern Vietnam.
