Elevated risk from estrogens in the Yodo River basin (Japan) in winter and ozonation as a management option

Popis výsledku v původním jazyce

A simple model was set up to predict estrogen concentrations and endocrine disruption risk in the Yodo River, Japan. This catchment spans the conurbations of Kyoto and Osaka and is the main source of drinking water for Osaka City, Japan. From the river survey data (5 separate occasions between 2005 and 2008), a maximum of 32 g per day estrone (E1) load was observed in the most downstream site of the river. Predicted E1 concentrations were in reasonable agreement with the measurements taken at several points within the basin from a series of sampling campaigns. The predicted concentrations exceeded a net estradiol (E2) equivalent of 1 ng L-1 on only a few occasions, suggesting that only limited endocrine disruption phenomena in fish along the Yodo Riveris likely. The model was then used to examine the impact on estrogen concentrations and endocrine disruption of a number of different scenarios. It was found that in-river biodegradation had little effect on predicted concentrations and
