“…These results suggest that accumulation of fluorochemicals in biota is different from those observed for lipophilic pollutants such as PCBs. The accumulation features of fluorochemicals are similar to those of contaminants like tributyltin, which bind to proteins (Kannan et al, 1997).…”

Furthermore, because only the dorsal ¢ns of the dolphins were examined, and lesions were observed on other parts of the dolphins when they could be photographed, the total levels of prevalence are likely to be higher still.…”

Experimental studies have highlighted the potential in£uence of contaminants on marine mammal immune function and anthropogenic contaminants are commonly believed to in£uence the development of diseases observed in the wild. However, estimates of the impact of contaminants on wild populations are constrained by uncertainty over natural variation in disease patterns under di¡erent environmental conditions. We used photographic techniques to compare levels of epidermal disease in ten coastal populations of bottlenose dolphins (Tursiops truncatus) exposed to a wide range of natural and anthropogenic conditions. Epidermal lesions were common in all populations (a¡ecting 460% of individuals), but both the prevalence and severity of 15 lesion categories varied between populations. No relationships were found between epidermal disease and contaminant levels across the four populations for which toxicological data were available. In contrast, there were highly signi¢cant linear relationships with oceanographic variables. In particular, populations from areas of low water temperature and low salinity exhibited higher lesion prevalence and severity. Such conditions may impact on epidermal integrity or produce more general physiological stress, potentially making animals more vulnerable to natural infections or anthropogenic factors. These results show that variations in natural environmental factors must be accounted for when investigating the importance of anthropogenic impacts on disease in wild marine mammals.

Additional screening panels have been deployed at FIT. Concepts currently under evaluation include:• The effect of oil incorporation into non-silicone coatings with poor foul release characteristics • The effect of loading level of the oil on foul release properties • The effect of molecular weight and water solubility of the oil on foul release properties About 58 panels are deployed at MMRTS and include two panels each of the downselected compositions. Data collection continues on the first and second downselect panels at FIT, Bridger Scientific, University of Hawaii and SUNY Buffalo. DISTRIBUTION STATEMENT A Jkpptarmd im prablto irataaBSj Dterfbiattaa Unlimited 014DTIOQüAUTTörSHBOraD I Static Immersion of Test CoatingsThe test coatings are applied to screening panels (4"xl0") for short term evaluation, and down select panels (10"xl2") for long term appraisal. A total of 143 screening panels have been exposed to barnacle fouling at the Florida Institute of Technology static immersion site since January 1997. 80 of these remain under test. A total of 39 downselect panels are currently under static immersion. Hard fouling adhesion measurements have been made on approximately 4,600 organisms on the screening panels and 2,300 organisms on the downselect panels. These include barnacles, oysters and tube worms. Hydrodynamic Foul Release /Skin Friction MeasurementsThe hydrodynamic foul-release and skin friction properties of the coatings continue to be evaluated using two instrumented foils that were specifically designed and constructed to accommodate standard 10"xl2" static immersion panels. Preliminary findings have been presented in a video, "Hydrodynamic Testing of Foul-Release Antifouling Coatings," April, 1998. Task 1.1.2: Field Exposure Testing (Bridger Scientific)Preseason inspection/testing of coatings in the first downselect matrix was performed on March 1998; data were presented and discussed in the 31 March 1998 Quarterly Report and the March program meeting, hosted by Florida Institute of Technology. The first routine inspection was performed in April at both the Brayton Point and Manchester Street Stations. At this time, all panels were photographed and assessed for fouling coverage. Panels in Series 3, 10, and 11 and one panel in Series 2 (Brayton Point) and Series 7 (Manchester Street) were removed and forwarded to Dr. Anne Meyer for post exposure analyses. These were replaced with panels in the second downselect matrix (Series 14-18). Coating formulations in both groups were inspected and tested again in May, 1998. The extend of fouling on the rest of the downselect panels is still relatively low, consisting primarily of soft fouling species. These were removed at pressures in the range of 50-100 psi (water jet). Incipient barnacle fouling was present on some panes (Series 1,2,6,7,9,12) but could also be removed at pressures between 75-100 psi. No other hard foulers were observed. Coatings in the second downselect group have been exposed approximately one month. At the time of inspection, most were...
