[The dynamics of 137Cs content in ontogenesis in barley grown on soil with background and increased contents of heavy metals].
The uptake by barley and the distribution between the vegetative and the generative organs of 137Cs, K and Ca was studied when plants were grown on soddy-podzolic soil with the background content of heavy metals and soil polluted with Cd and Co at concentrations significantly above the maximum permissible concentration (50 i 100 mg/kg accordingly). The reduction was found in 137Cs accumulation and removal with barley in ontogenesis under the action of increased contents of heavy metals in the soil, which was caused by their phytotoxic effect.
