Praćenje koncentracija platinskih metala i elemenata rijetkih zemalja u okolišu istočne Hrvatske

Introduction of catalytic converters in cars plays a vital role in the reduction of harmful emissions (VOCs, CO, NOx) but lead to a new environmental problem since catalysts emit several other elements (Pt, Pd, La, Ce, Nd, etc). In recent years, the utilization of REEs has been widely applied not only in industry and medicine but also in agriculture and forestry. A systematic study on the reaction of plants to PGE and REEs in this part of Croatia has not yet been presented. Using ICP-MS, PGE elements: Ru, Pt, Pd, Ir and REEs elements :Ce, La and Nd have been determined in Taraxacum officinale (dandelion ) samples collected along highways, streets and agricultural lands in eastern Croatia. Rare earth element concentrations in the leaves of dandelion from 28 sites in eastern Croatia showed higher concentrations in the plants from agricultural locations compared to those from nonagricultural. REEs in dandelion samples showed higher (non significant) concentrations in the plants from agricultural locations compared to those from nonagricultural.
