This monograph contains the proceedings of a Conference held in Pretoria in October Ig77_ Xne of the eleven papers are devoted compIete1y or predominantly to the analysis of essential or to-tic trace metals in various types of biological materials_ The features of several spectroscopic determination methods (atomic absorption spectroscopy. neutron activation anaiysis, microprobe mass analysis) are supported by information on wet and dry ashiug procedures. reliable digestion methods for the analysis of volatile metals and metalloids and on the frequently most critical task of accurate sampling_ This is followed by a discussion of some important physiological or toxicological aspects of the most significant essential or to_uic trace metals and an introduction on the genera1 aspects. trends and merits of analysis in medical diagnosis and treatmentA11 contributions are very well and concisely written by esperts and provide much interesting and stimulating information_ Therefore. this brief monograph is highly recommended reading for users of analytical data from bioIogica1 materials and also for those analysts who will enter the field_ Both groups will find this a comprehensive yet concise source of information on the potential and Iimitations of the treated spectroscopic methods and on the general prerequisites of sampling and sample pretreatment to obtain meaningful results in this important field of analysis_ H.

The first part of this volume deals with the applications of microcomputers in the study of microbial processes -2 detailed description is given of the aquisition and on-line analysis of data (e-g_. Oe and CO, tension, pH. foam formation. etc. in bioreactions)_ Part 11 concerns the theory. construction and use of dissolved oxygen electrodes and their applications_ The various calibration techniques are then examined. as well as the effects of temperature and liquid films on the ekxtrode. Possible sources of error in measurements are discussed_ Part III takes a look at probIems of power consumption in aerated stirred tank reactors_ The main principles of energy transfer and gas dispersion are described_ Part IV examines 100~ reactors from an engineering point of view. analyzing the thecry and principIes, fluidodynamics. gas and heat transfer as well as other physicochemical properties and characteristics of their construction_ Despite the highly specialized approach to the topics in this volume, all aspects are clearly described and are very well illustrated with graphs, tables and explanatory figures_ An up-to-date list of references completes each chapter_ L.
