However, the behavior of estrogen in an estuary is still little known. In this study, the behavior of 17β-estradiol (E2) in an estuary was determined by batch-mixing experiments using river water and seawater focusing on the behavior of E2 upon its coagulation with dissolved substances. Artificial river water enriched with E2, humic substances and iron and river water collected from an urban area were tested in the mixing experiments. When using artificial river water, most of the dissolved humic substances derived from sediment of the estuary were determined to exist as dissolved organic carbon after mixing with seawater. Similarly to the artificial river water, dissolved organic matter in river water stably existed as a dissolved fraction after mixing with seawater. Therefore, a large part of the dissolved organic substances in river water comprising humic substances remained in the dissolved fraction after mixing with seawater. In contrast, more than 80% of the dissolved iron in both artificial river water and urban river water coagulated and was removed from liquid phase. In the mixing experiments it was observed that the E2 concentration did not decrease and that E2 remained in the dissolved fraction of the mixture. From the results of the batch-mixing experiments, we conclude that the behavior of E2 in river water differs from that of dissolved iron, which coagulated upon mixing with seawater, and it is stable in a mixture of river water and seawater.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty
