Abstract

InMae Tot District, Tak Province, Tliailand, concerns have been raised oveb cadmium contamination, potentially due: to zinc mining activities. Although tdeoe is no report of acute toxicity on animals in this area, the impact of long-term environmental exposure to cadmium on their health are of attention. Water and sediment samples colleoted from iwo field sites (low-Cd and high-Cd sitesf in Mae Sot during 2008 were analyzed by GFAAS. Year round cadmium contamination in water ranged from 0.0015-0.002 mg/L in low-Cd site to 0.0019-0.0023 mg/L in high-Cd site, while higher lrvels were found in sediment ranged from 0.1013-0.2206 mg/kg in low-Cd site to 2.9260-3.288. mg/kg in high-Cd site. Microhyla fissipes was collected from each habitat in 2-month interval during wet season. Detectable level of cadmium residue was found only in the frog collected from high-Cd habitat. Gravimetric analysis showed that hepatosomatic indices were significantly higher in high-Cd habitat. Histopathology showed several similar alterations in the liver, however higher number of melanomacrophage center was found in high-Cd habitat. Renosomatic indices and kidney tissue alterations were not significantly different between two sites. Reproductive health in term of gonadosomatic indices (GSI) was not significantly different between male frogs from both habitats. BuZ in the females living in high-Cd habitat, significantly lower GSI were observed. The results indicate that exposure to environmentally relevant dose of cadmium mar interfere with the frog; health Using the frog as rsentinel species in this study suggests an important impliaatinn for overall health oo animals/human in this area.
