Geochemical composition of cabbage tissues exposed to Great Salt Lake dust in a greenhouse experiment

This dataset contains elemental concentrations measured in the tissues of Chinese cabbage (Brassica rapa ssp. Pekinensis) following controlled exposure to dust from the dry Great Salt Lake (GSL) lakebed. Plants were grown in a greenhouse using an inert growth medium and subjected to foliar dust application, soil dust amendment, or control conditions. Plant tissues were separated into roots, old leaves, and young leaves, ashed, digested in aqua regia, and analyzed by ICP-MS. The dataset includes treatment-level and tissue-specific metal(loid) concentrations and supports evaluation of plant-availability and potential indirect dietary exposure to metals associated with GSL dust.

本数据集收录了经受控暴露于干燥的大盐湖（Great Salt Lake，GSL）湖床粉尘后，大白菜（Brassica rapa ssp. Pekinensis）组织内的元素浓度检测结果。实验植株采用惰性生长基质在温室中栽培，分别接受叶面喷施粉尘、土壤施入粉尘处理与空白对照组处理。将植株组织分为根、老叶与幼叶后，进行灰化处理，以王水消解，并通过电感耦合等离子体质谱（ICP-MS）完成分析。本数据集涵盖不同处理组与组织特异性的金属（类金属）浓度数据，可用于评估GSL粉尘关联金属的植物生物有效性以及潜在的间接膳食暴露风险。
