“…Marine bivalves are susceptible to sublethal effects of TBT. Shell deformities and reduced growth occurred in the Sydney rock oyster ( Saccostrea commercialis ) at tissue concentrations of 80 to 230 ng Sn/g wet weight [27]. The initiation of shell malformation in the Pacific oyster ( Crassostrea gigas ) can occur at body concentrations as low as 12 ng Sn/g wet weight [28].…”

The chronic toxicity of tributyltin (TBT) was examined by exposing two successive generations of the freshwater amphipod, Hyalella azteca, to sediments spiked with TBT. Survival was the most sensitive measure of effect, with lethal concentration resulting in 50% mortality (LC50) values on a water and body concentration basis ranging from 76 to 145 ng Sn/L and 2,790 to 4,300 ng Sn/g, respectively. Individual growth of amphipods was not negatively affected by TBT, and although reproduction might be more sensitive than survival, the data were too variable to use on a routine basis. There were no detectable TBT-induced differences in the response between first- and second-generation animals. The relationship between toxicity and bioaccumulation of TBT in H. azteca was determined and can be used as a tool to predict the toxicity of TBT in environmental samples. Body concentrations exceeding 2,000 ng Sn/g in H. azteca exposed to field-collected samples would indicate that chronic toxicity due to TBT is likely occurring in amphipod populations at those sites.

“…A paucity of TBT residue data exists for seafood caught commercially from traditional fishery grounds. However, several studies (Batley, 1989;Kannan, Tanabe, and Tatsukawa, 1995;Kannan et al, 1996;Krone et al, 1989;Krone, Stein and Varanasi, 1996;and Scammell, Batley, and Brockbank, 1991) have reported concentrations for species collected for food, either from the open ocean or from another location used for commercial harvest of seafood. In addition, Cardwell, Simmonds and Keithly (1999) present results from a market basket survey of the U.S. in 1989 and 1990.…”

This study reports concentrations of tributyltin in seafood collected from eight sites around the world and assesses potential human health risks. Samples of fish, crustaceans, cephalopods (i.e., squid), and bivalve molluscs were purchased from markets in two Asian cities, one Australian city, three European cities, and two North American cities. Samples were then analyzed for tributyltin, and the chemical concentrations observed were used to calculate potential human health risks from consumption of market-bought seafood. TBT residues in marketable seafood were consistent worldwide, averaging 185 ng/g dry weight. For different reasons, pelagic fish and bivalve molluscs tended to have slightly higher residues than squid, demersal fish (sole/flounder) and crustacea. TBT concentrations in seafood from France and Korea were at least twice as high as those from the other countries. Based on average per capita seafood consumption rates for each country, the amounts of TBT ingested did not exceed proposed thresholds for chronic effects, suggesting negligible risks to the average consumer.

Ecological risk assessments of endocrine disrupting organotin compounds using marine neogastropods in Hong Kong

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.
