Research Abstract

Usage of methanogenic digestate of livestock excrements as fertilizer may lead to pollution of the surrounding aquatic ecosystems with estrogens contained in the digestate in the concentration order of several tens of ppb. To evaluate the potential environmental impacts of estrogens introduced to the agricultural production system, degradation of estrogens becomes an important factor. There are several reports concerning the degradation of estrogens in untreated livestock excrements and wastewater whereas there is no report on the degradation of estrogens in organic fertilizer applied to paddy fields. In this study, we investigated degradation of estron in the digestate by two incubation tests and a fractionation test using centrifugal ultrafiltration. Estron in the digestate was degraded rapidly by microbes in the extract of the soil collected from a paddy field whereas it was not degraded much by indigenous microbes in the digestate and the microbes in the BOD seed (HACH, Colorado). The binding of the estrogens with dissolved organic matter in the digestate was not significant, and suggesting that bulk organic substances in the digestate could not have contributed to the slow degradation of estron in the before the incubation of soil microbes. The results indicate that estrogens in the digestate applied to the paddy field should be rapidly degraded by microbes in the soil, and the possibility of ecosystems pollution is low.
