animals and, hence, potentially sick prior to stranding, it is possible that the animals were not foraging normally prior to stranding. In addition, these animals were collected from various areas around the bay, and, as location appears to influence the amount of OA present in samples ( Fig. 3), these animals may have been in residence in areas where OA exposure was less than estimated. Furthermore, since samples used in this assessment were collected for other purposes, limited tissue types were available for analysis. Had more turtle gastro-intestine kidney or liver samples been available, results from these tissue types may have yielded higher concentration of OA ( Toyofuku, 2006).
