Besides the three main chapters in part 2) dealing with bioassays on different systematic groups: microorganisms Bacteria, Protozoa, Phytop lankton -26 papers) invertebrates 15) and fishes 1 3 , the first part with 11 general and conceptional papers is of special importance for all environmental toxi- cologists. We ll known ecotoxicological author ities such as J R. PRATT, CAIRNS, . CALOW, . G DIXON and M. MUNAWAR iscuss various aspec ts of the scientific basis of bioassays, the inter compari son o f acute and chronic tests, the applicat ion of bioassa ys for the resolut ion o f envi ronment al prob- lems, impact assessment, ecosystem health assessment and government decision making. In the remaining bulk of original papers, methodicological studies are in good balance with “effect” investigations. All organismic levels from the biochemical response DNA) through single species tests to the holistic approach such as multispecies or mesocosmos assays are equally represented. Besides the ,,conventional“ liquid phase studies, sediment bioassays have become a focus of interest. Al l this valubale, detailed information can serve as a basis for early warning and for predictive and preventive strategies for environmental man agemen t. Unfortunately, the attempt to reach a general conclus ion state of the art evaluation) is lso missing in this volume, despite the presence o f competent scientists. Regrettably, there is also no author or subject index. But there is no doubt that this highly recommendabl e boo k will cont ribute to its own dictation:-“t o our common future through sustain- able environment”. JORG-A.

A n accelerated rise of sea lev el threat s the coastal human being in the next future. The presented book brought together the written versions of presentations from an international workshop on these problems held in November 1988 on Texel, Netherlands. It was concentr ated on marine c oasta l environment , particularly in soft sediment areas at temperate latitudes. The volume contents 23 contributions: climate changes 3, elevated C02-concentrations 3 temperature changes 6, sea-level rises 9, UV-B radiation 2. The authors were making an inventory of present knowledges, identification of uncer- tainties and formulation o f research needs. While the increa se of the C02- lev el might lead to an increased productivity, others could be exclus ively detrimental , e.g. the incre ase of UV-B irradia- tion. The sea-level rise in coastal areas will depend largely on geomorphological pr ocesses, in par- ticular on the net result of changing rates of sedimentation and erosion. Temperature changes will probably cause shifts in the areas of distribution o f gre at numbers o f pla nt and anima l species. That can induce an imbalance o f the ecosystems and extinction of rare and sensitive species. The presented contributions reflect the many uncertainties in the field of the “ greenhouse pro cess”. The book is well prepared. It is useful to all who are interested in the consequences of the ongoing changes. U SCHIEWER North Sea-E stuaries Interactions.
