“…If ISI b2 in Littorina L., most females will have been sterilized [102]. Laboratory simulative experiments and field investigations show a good positive relationship existing between degrees of imposex and ambient TBT exposure levels [101,103]. These indexes, such as VDSI and ISI thus provide very good estimates of the reproductive capability of females in analyzed populations and have been widely used in surveys all over the world.…”

“…Higher values have been obtained in other studies of conspecifics, body TBT burden of 43-74 ng Sn g À1 dw has been recorded in T. clavigera around mariculture areas in Taiwan (Hung et al, 2001). TBT concentrations of 5-508 ng Sn g À1 dw had been recorded in T. clavigera along the Korean coast, with generally >200 ng Sn g À1 in animals near harbours and shipyards (Shim et al, 2000). Horiguchi et al (1994) examined imposex and organotin levels in T. clavigera in Japan, TBT levels, measured in ng g À1 as chloride in wet weight, were up to 420 (%185.3 ng Sn g À1 wet weight).…”

“…3), represented by male-biased population in sites with severe organotin contamination. The TBT related sex ratio alternation has been reported in T. clavigera (Tan, 1997;Blackmore, 2000;Shim et al, 2000;Li, 2003) and other gastropods, such as N. lapillus , T. biserialis (Ramasamy and Murugan, 2002), Ocinehrina aciculate (Oehlmann et al, 1996b). The affected population may suffer from reproductive failure and even local extinction (Gibbs and Bryan, 1996;Evans et al, 1996).…”

As active ingredients of anti-fouling paints that are widely used on ship hulls, organotin compounds, in particular tributyltin (TBT), are well-known endocrine disruptors causing sex changes in marine organisms and widespread in coastal waters and sediments worldwide. In this study, a comprehensive ecological risk assessment (ERA) of organotins was conducted in Hong Kong waters through determining the imposex status, sex ratio and tissue burdens of these compounds in the neogastropods, Thais clavigera and Thais luteostoma collected from 29 coastal sites. We also investigated the historical trend of organotin effects on these gastropods, and performed a probabilistic ERA based on tissue burden of TBT in the animals. Our results demonstrated that imposex indices were positively correlated with the body burden of organotins in the gastropods. Across all sites, the sex ratio (female:male) decreased significantly with increasing imposex levels or tissue burden of organotins, implying that such pollutants can result in a male-biased population, potentially leading to local extinction in extreme cases. Based on the ERA, 5.4% of all populations of T. clavigera are at risk due to exposure to TBT; the risks include growth inhibition, impairment of immune functions and reduced fitness. Seriously impacted areas included Aberdeen, Repulse Bay, Butterfly Beach, Mui Wo and Ha Mei Wan. A comparison with historical data revealed that there had been some improvement in the areas with low marine traffic, and distant from the major harbour/port. This could partly be due to the restriction on the use of TBT on small vessels (<25 m in length) since 1992. Nevertheless, the organotin contamination still remains severe in areas with high marine traffic or adjacent to large harbours/ports. In particular, the situation in the northeastern waters of Hong Kong has been getting worst since 1996 that is probably associated with the rapid development of the cargo container port at Yantian in China.

: Digestive cells of the bivalves have a highly developed lysosomal system and the system is known to be sensitive to changes in environmental qualities. In this study, we measured lysosomal responses of the digestive cells in wild oyster, Crassostrea gigas using frozen section. Oysters were collected in June 2010 from intertidal areas in the inner and outer bay of Gwangyang off the south coast of Korea. From the tissue sections, we measured the digestive cell lysosomal membrane stability (LMS), level of neutral lipids (NL), lipofuscin (LF) and the digestive gland atrophy (DGA). The DGA and condition index of oysters from the inner bay were significantly lower (P<0.05). The statistical test indicated that LMS levels of oysters in the inner bay and the outer bay were not significantly different since a shorter activity was displayed by oysters from the inner bay than that of oysters in outer bay. The LF deposition level of the oysters in the inner bay displayed significantly higher levels than the outer bay (P<0.05). In contrast, the NL accumulation measured from oysters in outer bay was significantly higher than the level observed in the inner bay (P<0.05). Different levels of DGA and LF that were observed in the inner and outer bays were thought to be associated to different level of environmental contamination and these two assays are considered to be good biomarkers.
