Increasing levels of tributyltin-induced imposex in muricid gastropods at Phuket Island, Thailand

New Imposex Development Index (IDI) for Stramonita haemastoma (Mollusca: Muricidae): A Transplantation Experiment in the Brazilian Northeast

“…A similar transplantation study was carried out in Korea with Thais clavigera, where the females showed a significant growth of the penis after 32 days of the beginning of the study (Shim et al, 2000). Bech (1999b) observed in Taiwan the appearance of imposex in T. distinguenda after 80 days of exposure, but in a low percentage of individuals (18.5%). After this, Bech et al (2002) verified 45% of incidence of imposex, yet only after five months.…”

Imposex and surface sediment speciation: A combined approach to evaluate organotin contamination in Guanabara Bay, Rio de Janeiro, Brazil

“…Recently, high concentrations of organotins were detected in sediments from tropical areas (Kan-atireklap, Tanabe, & Sanguansin, 1997a, 1997bKo, Bradley, Neller, & Broom, 1995;Tong, Pang, Phang, & Lai, 1996) and several reports of imposex showed also organotin impacts in these areas (Bech, 1999a(Bech, , 1999bBlackmore, 2000;Ellis & Pattisina, 1990;Reitsema & Spicket, 1999;Swennen, Ruttanadakul, Singh, Mensink, & tenHallers-Tjabbes, 1997;Tan, 1997Tan, , 1999. A number of recent publications describe the occurrence of imposex in gastropod populations in Latin America coasts (Gooding, Gallardo, & Leblanc (1999), Chile; Castro, Cascó n, & Fernandez (2000), NE Brazil; Fernandez, Limaverde, Castro, Terra, & Wagener (2002a, 2002b, SE Brazil; Penchaszadeh, Averbuj, & Cledó n (2001), Argentina).…”
