 note = {Immersion and field surveys were conducted in the northwestern part of Kyushu, to investigate the estrogenic activity in male Japanese common goby. Serum vitellogenin (Vg) concentration and total estrogenic activity in male common goby, based on microanalysis of natural estrogens (E1, E2, E3) and estrogenic compounds (NP, BPA, OP), were measured. The immersion survey in Ariake Sound suggested the possibility of the progress of environmental estrogen pollution. Field surveys in Ohmura Bay and Ariake Sound also detected estrogenic activity. An extremely high ratio of Vg-positive males were recorded in Ohmuta River Estuary, and total estrogenic activity in environmental water in this site were also higher than that recorded in other sites. The main causative substance of the estrogenic activity was not alkylphenols, but natural estrogens (E2), probably due to a high population density and a low sewage diffusion rate., Nagasaki University Major Research Project: Restoration of Marine Environment and Resources in East Asia, Coastal Environmental and Ecosystem Issues of the East China Sea ,pp.205-213; 2010},
