STATEMENT ON RECENT OYSTER STUDIES – November 17, 2003

A recent paper on the Pacific Oyster (Crassostrea gigas) by Dr. Helen Nice et al. is an example of the use of preliminary protocols in an attempt to test the effects of compounds with endocrine activity on molluscs. There are currently no validated protocols available for this purpose for molluscs; even the basic husbandry requirements have not been defined.

Experts in oyster biology at the Academy of Natural Sciences' Estuarine Research Center (ANSERC) in St. Leonard, Maryland agreed that the low number of oysters and other study design factors in the Nice et al. study were not sufficiently robust to support the author's sweeping conclusions about the relevance of the study. According to George Abbe, Academy of Natural Sciences, the work of Nice et al. is interesting, but should be supported by more rigorous testing and a larger sample size in order to draw valid conclusions.

Nonylphenol has been the subject of hundreds of studies on dozens of aquatic species and several risk assessments have been conducted. While the Nice et al. study would not meet the quality requirements for inclusion in most regulatory assessments, the conclusions about this compound obtained using quantitative risk assessment would not change even if this study were included.
