抄録: Contamination of estrogen-like substances (ELSs) in the river and coastal areas in Thailand and Malaysia was investigated using transgenic medaka, which indicates estrogenic contamination level as green fluorescence in its liver. Water samples were collected from two rivers in Thailand, four rivers in Malaysia, and three coastal areas (two in Thailand, one in Malaysia). Generally, no contamination was observed in headwater, river mouth, countryside, and coastal areas. On the other hand, detectable levels of contamination were observed in the river water of urban area. These suggest that contamination by estrogenic substances occurs in urban area, but these substances may be diluted and/or degraded to the undetectable levels until the water reaches river mouth. Relatively high levels of ELSs were observed at Sang Khep River mouth in Thailand and toxic effects were observed in urban area of Sang Khep River as well as urban area and the mouth of the Klang River in Malaysia.
