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.
