Symposia Biologica Hungarica 29. - Heavy Metals in Water Organisms (1985)

HEAVY METALS IN WATER ORGANISMS Edited by J. SALÁNKI (Symposia Biologica Hungarica 29.) Chemical substances of anthropogenic origin polluting surface waters are dangerous to aquatic organisms and have varying effects on microbes, plants and animals. Living organisms frequently accumulate pollutants, signalling in this way their presence in the environment. Accumulation is particularly characteristic of heavy metals entering surface waters as industrial, agricultural and communal wastes. Heavy metals have come into the focus of environmental biological research all over the world. Beyond the monitoring of pollu­tion, special attention is being paid to the various organisms which make early detec­tion possible. The papers in this volume were presented at a symposium held in Hungary at which scientists from 12 countries provided in­formation on the latest results in this field. The most important topics discussed were accumulation of heavy metals, ecological monitoring of heavy metal pollution, organ­isms as indicators and the effect of heavy metal pollution on vital functions. The Hun­garian participants gave an account of the state-of-the-art of research into the heavy metal pollution of Lake Balaton for the first time. The seriousness of the problem of heavy metal pollution is reflected by the fact that it has assumed prominence in one of the main projects of IUBS. AKADÉMIAI KIADÓ•BUDAPEST ISBN 963 05 4195 5
