“…At the light microscopic level, the ovaries of B. areolata at lower imposex stages, at least up to stage 4, exhibited the normal histological structures as pure females (stage 0) (unpublished results); this is in line with the observations in other prosobranchs, e.g. Ocinebrina aciculata (Oehlmann et al 1996), Bolinus brandaris (Ramon and Amor 2001) Buccinum undatum (Mensink et al 2002) and Thais rufotincta (Cheng and Liu 2004). In contrast, previous studies have demonstrated that imposex females induced by TBT-after a severe spill incident (at the stages 5 and 6)-may exhibit two unnatural conditions: a suppression or impairment of oogenesis and a development of spermatogenesis in the ovary (Oehlmann et al 1996;Axiak et al 2003;Horiguchi et al 2006).…”

Ultrastructure of oogenesis in imposex females of Babylonia areolata (Caenogastropoda: Buccinidae)

During a tributyltin (TBT)-exposure experiment, the ultrastructural features of oogenesis have been examined in TBT-induced imposex females of Babylonia areolata and compared with those of the normal female. The results obtained from such experiment demonstrates that B. areolata exhibits a low to moderate intensity of imposex because all VDSI values are never higher than 3. Ultrastructures of germ cell development including oogonia, pre-vitellogenic, early vitellogenic, late vitellogenic and mature oocytes show that oogenesis in imposex female is similar to that of normal females except for the presence of numerous lipid droplets in the cytoplasm of the oocytes and the follicle cells in imposex females, indicating the degeneration of their oocytes. Vitellogenesis in B. areolata involves both auto-and heterosynthetic processes that resemble those of the basal gastropods and the pulmonates. In addition, the presence of cortical granules and microvilli are unique structures of this species.

“…Up to date, different criteria-dependent schemes have been proposed for the description of imposex (Axiak et al 1995, Barreiro et al 1999, Mensink et al 2002. To make a scheme more applicable for general use, 2 questions should first be clarified: (1) What is the purpose of scheme?…”

“…For example, Hexaplex trunculus with aborted egg capsules is still classified as Stage 5 (Axiak et al 1995). To make the identification easy, several schemes are proposed for specific species, based on different criteria (Axiak et al 1995, Barreiro et al 1999, Mensink et al 2002. For example, Barreiro et al (1999) proposed a specific scheme for DS in Nucella lapillus solely based on vas deferens development instead of vas deferens and penis development in the typical scheme.…”

We investigated the occurrence of imposex in gastropods from the coastal waters of mainland China from November 1999 to July 2004. Imposex was found in 30 species from 8 families, and was recorded in 20 species for the first time. In addition to the already known phenotypes of imposex expression in Cantharus cecillei, we also found aborted egg capsules in specimens with a split ventral channel (stage and type classification: S 6c* ) and various extensions of the proximal vas deferens (PVD). The PVD went up to or passed by the vaginal opening, and then it stopped or continued along the capsule gland. In imposex females, the penis shape and the development of the vas deferens were similar to those of the male of the same species. The morphological expressions of imposex showed diverse stages and types. Reproductive failure of females occurred in 13 species. The results suggest that imposex is widespread and severe in the coastal waters of China. Based on our aims of ecological and morphological significance, a typical imposex classification could be further generalized for all 30 species by adding S 6c(*) and 2 subdivisions of the PVD. The generalized scheme was also ascertained to be valid for several morphological variations of imposex in previous work. Sterility at S 6c(*) was proven to be due to the infolding of the capsule gland wall. We thus summed up 4 mechanisms of sterility (a, b, c and *) in females. Furthermore, it was shown that the normal structure of the male genital system also affected the morphological expressions of imposex to some degree, which we referred to as 'effect of male structure'. Finally, we put forward a general classification scheme of imposex with an integrated system of aims, criteria, stages, types (subtypes), pathways and mechanisms of imposex.

“…These anti-fouling compounds leach into the marine environment and have caused shipping-related accumulation of TBT in sediment resulting in the chronic exposure of aquatic organisms (Matthiessen 2013). A wellknown effect of TBT exposure is imposex in gastropod molluscs such as marine whelks (Mensink et al 2002). Imposex is the formation of male characteristics in female snails.…”

Low organotin contamination of harbour sediment in Svalbard

Arctic sea routes are opening up for maritime transport due to sea ice retreat leading to increasing human activities in the Arctic and concomitant pressures on the environment. Organotin compounds are used in antifouling paints of large seagoing vessels and are known to leach into the marine environment and accumulate in sediments and biota. As organotin levels in Svalbard sediments have not been documented in peer-reviewed literature before, this study describes the levels in sediment of harbours around Svalbard (Ny-Å lesund, Longyearbyen, Svea, Pyramiden and Barentsburg). Organotin levels in sediments of Svalbard harbours were low (below the detection limit up to 14 ng Sn/g dw sum-butyltin) compared to other Arctic regions with a longer history of shipping. Levels were below known no effect levels and in accordance, no imposex was found in marine whelks from Ny-Å lesund harbour. Of all other analysed compounds in sediments of Kongsfjorden (polycyclic aromatic hydrocarbon (PAHs), polychlorinated biphenyls, polybrominated diphenylethers and perfluorinated compounds) PAH levels were highest and in one sample above action levels. It is advised to continue monitoring contaminant levels, for which the current results form a good basis. If contaminant levels rise, mitigation measures can be taken in time.
