A monitoring survey was conducted to investigate the distribution of steroid estrogens and their conjugates in surface sediments of Tokyo Bay for the first time, which is known as one of the most heavily polluted marine embayments in the world. Th...
Three-dimensional distributions of fluorescent whitening agents (FWAs: more specifically, DSBP and DASI), which are sewage-derived water-soluble markers, were observed in Tokyo Bay water through multi-layer sampling of water at 20 locations. In su...
A method was developed for the simultaneous trace analysis of linear alkylbenzene sulfonate(LAS) and their biodegradation intermediates, sulfophenyl carboxylates (SPC), in sewage effluent and river water. Sensitive determination using a liquid chr...
Two kinds of stilbene-type fluorescent whitening agents (i.e., DSBP and DAS1), minor components of laundry detergents, were analyzed in surface waters of Tokyo Bay and adjacent rivers and in sewage effluents to examine their usefulness as molecula...
