Abnormalities in sexual development of the amphipod Gammarus pulex (L.) found below sewage treatment works
Increasing numbers of widely used industrial, agricultural, and natural chemicals are known to elicit endocrine‐disrupting effects in a wide range of vertebrate and invertebrate species.

| description | Increasing numbers of widely used industrial, agricultural, and natural chemicals are known to elicit endocrine‐disrupting effects in a wide range of vertebrate and invertebrate species. The objective of this study was to determine whether the sexual development of the freshwater crustacean Gammarus pulex (L.) was affected below sewage treatment works (STW) previously known to contain endocrine‐disrupting chemicals in their effluent. The gonadal structure, external sexual characteristics, and size of gammarids from exposed sites were compared to those of gammarids from a reference site. No significant difference was found in the gonadal structure of males collected below two STW. However, a highly significant number of females collected from a site known to elicit high estrogenic responses in vertebrates displayed an abnormal structure of oocytes in vitellogenesis. Body size was significantly shorter and male/female size differential was significantly reduced below one of the STW. Analysis of gnathopod and genital papillae length data suggests that different allometric relationships of these organs to body size exist between sample sites. |
