In our previous study, we proposed a unique sampling technique for mutagens in marine environment by suspending an absorbent, blue rayon, selective to polycyclic mutagens with three or more fused rings. By using this technique, we were able to bring back a small amount of adsorbent, weighing less than 10 g, from remote sampling sites, rather than large volumes of water. In the summer of 1990, a collision of barge tankers occurred in Galveston Bay and approximately 500,000 gal of oil were spilled into the Bay. Several sites in Galveston Bay were sampled 5-7 d after the oil sill. We characterized the pollutants chemically and detected the mutagenicity. We designed the present study to examine the applicability of our technique from two points of view. One was to determine if there was a correlation between mutagenicity of blue rayon-adsorbed compounds and the level of known mutagens detected in water samples from the same site. The other was to certify if the sampling technique provided a convenient method for handling water samples collected at remote sites. The chemical analysis was carried out in Texas (U.S.A.) an the mutagenicity testing was done in Okayama (Japan). 7 refs., 2 figs., 1 tab.
