existing technical reports and then wait for papers that will arise. One selection of these will be in a special issue of this journal in the second half of 1992. If people want to know what happened, and to read what the results could be on the ecosystems that are there, added to brief scene-setting accounts of the oil history and main wildlife of the region, then this book fits their need very well indeed.

Canadian Oilspill Specialists 1991 Directory of Canadian Marine Oilspill Specialists. J. P. Harper, J. Dempsey, W. Duval, J. Haggarty, B. Humphrey, L. Solsberg & G. Tidmarsh. 118 pp. Harper Environmental Services. Sidney, B.C., Canada. 1991. This directory provides annotated listings of Canadians with marine oil spill experience. It is a means of locating individuals with a range of expertise, when such people are needed quickly at the time of a spill. There are four sections: the whole listing, and listings by Arctic, Pacific, and Atlantic Regions. There are two indices for each of the four sections. The Glossary index allows, for example, finding aquaculture or mapping experts with spill experience. The Spill Experience index shows who, from any field of expertise, worked on which spill. The index has world-wide value, as was shown by the recent gulf-war marine discharges. Monitoring and clean-up specialists had to be assembled quickly from many countries. The Exxon Valdez spill also drew on experts from around the world. Efficient spill responses are now international, and need to have directories like this readily available. The index is available in hard-copy at CanS20.00 plus postage. Electronic copies are available in ASCII files format, Word-perfect 5.0 file format, and dBase III+ file format (.DBF and .NDX files) at the same price.

New Water Quality Standard BSI continues its contribution to international standards for water quality with the publication of BS 6068, Section 6.5, 1991. This document, which provides guidance on sampling of drinking water and water used for food and beverage processing, is identical with the International Standard ISO 5667-5, 1991. Sampling is undertaken for a number of purposes, such as determination of the efficiency of the treatment plant, monitoring of the water leaving the treatment plant and assessment of the effects of materials on 120
water quality. It is important that the sampling purpose be defined as accurately as possible and that the measurements yield results in the most efficient and statistically representative manner. BS 6068, Section 6.5 provides expert guidance in achieving these objectives. The guidance given covers the design of sampling programmes and techniques, handling and preservation of samples, water processing in a treatment plant (including the analysis of raw water), supervision of the treatment plant and the distribution system and the identification of defects in the system. No current standard is superseded. It is one of a group of standards dealing with the sampling of specific types of water, and should be read in conjunction with BS 6068, Sections 6.1, 6.2 and 6.3. These publications deal respectively with the design of sampling programmes, sampling techniques and the preservation and handling of samples. General terminology used accords with that in BS 6068, Section 1.2. BS 6068, Section 6.5, 1991 is available at the price of £11.25 to BSI members and £22.50 to non-members from BSI Sales, Linford Wood, Milton Keynes, MK14 6LE, UK.
New Integrated Process Controller-Recorder The PXR 105--a new integrated process controllerrecorder combining advanced digital control facilities with a high performance circular chart recorder--has been launched by ABB Kent-Taylor. It provides a costeffective and reliable permanent record of process parameters and has been specifically designed for control and recording in batch process industries, such as food, pharmaceuticals and heat treatment. The PXR 105 features up to two control loops and three recorder channels. Each control loop has advanced self-tune facilities on start-up or set point which are individually operable in ratio or cascade application. High visibility alpha-numeric displays of set point and measured value, together with a bar graph deviation display are also incorporated. The recorder channels can be set to monitor the control parameters or a comprehensive range of process inputs including thermocouples, resistance thermometers, flow signals in addition to conventional transmitters, pneumatic signals, voltage and current. Although offering advanced and comprehensive facilities, the PXR 105 is simple to use and to configure, using an alpha-numeric menu and prompt system with diagnostic displays to assist if required. Technical features include bumpless auto/manual switching, local or remote set point, up to 10 alarms per loop with selectable type and function, and up to four alarms assigned to the recorder channels. Display facilities include two rows of six characters per channel with individual status indicators for alarm, local/remote set point, self-tune and auto/manual output control, together with deviation bar graph display.
