81:6527 Obana, Hirotaka, Shinjiro Hori and Takashi Kashimoto, 1981. Determination of polycyclic aromatic hydrocarbons in marine samples by high-performance liquid chromatography. Bull. environ. Contamin. Toxicol., 26(5):613-620. The method yielded better separation and higher sensitivities of PAH's in samples of sediment, oyster and wakame seaweed (Osaka, Japan) than did GLC, GC-MS or TLC-fluorescence techniques. PAH concentrations and distributions are discussed and related to the level of petroleum contamination. Osaka Prefectural Inst. of Public Health, 3-69, Nakamichi 1-chome, Higashinari-Ku Osaka 537, Japan. (bwt) 81:6528 Roses, O.E. et al, 1980. [Pollution of the Argentinian sector of the Southern Ocean. II. Mercury. III. Arsenic. IV. Organochlorines.] Contrnes Inst. antart, argent., 4:47-54; 125-132; 139-153. (In Spanish.) Inst. Antartico Argentino, Buenos Aires, Argentina. 81:6529 Rossi, S.S. and W.H. Thomas, 1981. Solubility behavior of three aromatic hydrocarbons in distilled water and natural seawater. Environ. Sci. Technol., 15(6):715-716. Solubilities of toluene, acenaphthene, and pyrene were determined at 25°C in seawater and distilled water. Magnitude of the 'salting-out' effect and the effect of temperature on solubility were directly related to hydrocarbon molar volume. Results of toxicological studies using aqueous solutions of aromatic hydrocarbons could be artificially affected
if temperature is not closely monitored. Scripps Inst. of Oceanography, La Jolla, Calif. 92093, USA. (bwt) 81:6530 Voutsinou-Taliadouri, F., 1981. Metal pollution in the Saronikos Gulf [Greece]. Mar. Pollut. Bull., 12(5): 163-168. Inst. of Oceanographic and Fish. Res., Athens, Greece.

Oceanogr., 26(3):492-499. Surface film formation and breakup rates are measured, as are activation energy and time to equilibrium. Results indicate that a nearly always present organic film on the ocean surface affects both the mechanism and rate of transport of substances across this boundary. Pravdic: Center for Mar.

At 1.5 m above a soft bottom in 10-m depth near the island of Ask~ (Sweden), particulate settling in interceptor traps was investigated in an environment with moderate turbulence and currents. Consistent
trapping in cylinders with an interior diameter of 21-57 mm requires a height:diameter ratio >/3. Cylinders with small diameters strongly concentrated organic matter.
