This study analyzed 27 surface sediment samples from the Tamaulipas Continental shelf to determine the spatial–temporal distribution of V and Cd (spring–summer 2016; summer 2017). Average V concentrations (99 ± 18 mg g⁻¹) were similar to that previously reported values for the area, while average Cd concentrations reflect uncontaminated sediments at surface level of the shelf. Inputs of V and Cd may be related to hydrocarbon and anthropogenic contributions from South and North of the Gulf of Mexico. The variability shown by both elements results from the hydrodynamics and hydrology of the area produced by local currents, eddies of the Loop Current, resuspension of fine sediments and contribution of terrigenous material. Considering that both metals showed significant differences (Shapiro–Wilk, p = 0), baseline concentrations could not be established, instead a reference interval of 79–122 µg g⁻¹ for V and 0.121–0.258 µg g⁻¹ for Cd in sediments from the Tamaulipas platform is suggested.

本研究分析了来自塔毛利帕斯大陆架的 27 个表层沉积物样本，以确定 V 和 Cd 的时空分布（2016 年春夏；2017 年夏）。平均 V 浓度 (99 ± 18 mg g ^-1 ) 与先前报道的该地区值相似，而平均 Cd 浓度反映了大陆架表面未受污染的沉积物。V 和 Cd 的输入可能与墨西哥湾南部和北部的碳氢化合物和人为贡献有关。两种要素显示的可变性是由当地水流、环流涡流、细沉积物的再悬浮和陆源物质的贡献所产生的该地区的水动力和水文造成的。考虑到两种金属都表现出显着差异（Shapiro-Wilk，p = 0 )，无法确定基线浓度，建议在 Tamaulipas 平台的沉积物中，V 的参考区间为 79–122 µg g ^{-1 ，Cd 的参考区间为 0.121–0.258 µg g -1 。}
