Varga J. Dynamics of migration and accumulation of Lead in mosses communities of invertebrates in the National park "Bjukk" (the Hungarian Republic).

The general laws and pathes of receipt of lead to assemblages of invertebrates of mosses communities, features of its migration and accumulation are established; possibility and expediency of use for the purpose of bioindication of indicators of a species composition of invertebrates in the zoocenosises dated for mosses, growing in the conditions of various level of contamination of ecosystems is found out by heavy metals. Levels of accumulation and feature of accumulation of lead by the population of mosses communities are defined. It is found out that in organisms of Colembols (consumer of the first order) near to a highway the quantity of lead on the average in 2, 1 time exceeded parameters on a control field; the accumulation maximum level is noted in organisms consumers the second and third order (labours Staphylinidae, Chilopoda). For the season which has passed since introduction in action of an interdiction for use containing lead kinds of fuel quantity accumulated in organisms of Colembola of lead has decreased on the average for 69,2 %.
