We have previously reported that the practice using rock shells is useful for environmental educationin in lower secondary school. To obtain further information about collecting rock shells, we investigated the effects of environmental hormones on rock shells collected from the kumamoto and Fukuoka coastal waters. The rock shells with imposex were still found in Kumamoto coastal waters, even though the number of rock shells with imposex showed a tendency to be decreased. The occurrence of imposex was observed for rock shells inhabiting in harbor but not for these inhabiting in the sea shore. In the present data for investigation, there were many rock shells that were difficult to determine the sex.
