dicting the movement of oil slicks. Ocean Engng, 14(2):137-143.

In order to obtain quick initial guidance on a first estimation of motion of the spilled oil, a simple manual procedure incorporating advection and spreading processes has been devised. This pro- cedure involves the utilization of a nomogram based on simplified equations. Spill displacements through- out a given forecast period can be easily read from the nomogram. The technique is demonstrated with a real spill case. Atmos. Environ. Serv., 4905 Dufferin St., Downsview, ON, Canada.

active waste disposal: chemical control. Chem. Br., 23(5):448-454.

Low, intermediate, and high level waste categories are described including approximate annual pro- duction amounts for the U.K., and the basic aims of long-term radioactive waste disposal are discussed. The author suggests that although the emphasis of discussions and research on waste disposal has largely been on the strength of geological barriers (should the engineered barriers of containment fail), the chemistry in the vicinity of the waste can also provide an important barrier. In particular, the buffering and adsorptive properties of the cement surrounding the waste drums can provide protection. The high pH of the cement acts to control corrosion, maintain low solubilities, and restrict microbial activity. Environ. and Med. Sci. Div., AERE Harwell, Oxford OXl l 0RA, UK. (gsb)

Ibrekk, 1986/87. Models for calculating oil spill damages to shores. Oil chem. Pollut., 3(1):69-81.

The parametric calculation model uses the amount of oil in nearshore waters, oil characteristics, littoral area and wave exposure of the different types of shoreline as the primary input parameters. It simu- lates the sequence of events often observed during an oil spill; oil strands on the shore and is then subsequently redistributed and inundates new areas. As output, this model gives shoreline length con- taminated, amount of oil on the shore and density of oil on different shoreline types at selected times after the initial impact. The regression model is based upon reports from 25 spills worldwide. There is no correlation between shorelength damaged and amount of oil initially spilled. The calculation model seems to give better predictions of shoreline con- taminated that the regression model. However, verification requires data which are only recently being collected and reported.

Commerscheidt, 1987. Environmental specimen bank specific reference materials--main aims and preparation. Z. analyt. Chem., 326(7):707-711.

An environmental specimen bank (ESB) provides long-term high quality storage for a variety of reference materials (aquatic and terrestrial, including human), allowing the techniques of the future to be used in analyzing current materials. The ESB concept is discussed in general terms, and the specifics of a new ESB program in the Federal Republic of Germany is described, including prep- aration and characterization procedures.
