HEEP COPYRIGHT: BIOL ABS. Information is provided concerning the concentrations of As found in plants and soils from various sites in the United Kingdom that are enriched in As. Ecotypes of various species can accumulate As to extreme levels and these have been related to the total As present in the soils. Clonal material from one such species exhibited tolerance to AsO4 levels that were lethal to normal ecotypes. Interelement correlations were found for As and Fe in the aerial parts of the plants, but no such correlations were found between As and either Cu, Zn, Pb or PO4. Although As occurred at high levels throughout the plant, including the seeds, the highest concentrations were recorded in old leaves.
