TL;DR: The pharmaceutical residues from Scaynes Hill WTW were eventually discharged into the river Ouse, causing an elevation in their concentrations downstream of the outfall, confirmed by the good agreement between measured concentrations and those predicted by a simple dilution model.

TL;DR: An assessment of the impact of a recently commissioned, post-tertiary GAC plant in the removal of emerging contaminants in a working STW found a significant reduction in the concentrations of steroidal estrogens was observed.

TL;DR: Of the three popular techniques, the GC-MS technique is the simplest to operate, but fails to detect the estrogens at the lower-end of environmentally relevant concentrations, and is recommended to be the preferred analytical technique for routine analysis of estrogens in environmental water samples.

TL;DR: The findings confirm the effectiveness of a full-scale GAC in removing both estrogenic and anti-androgenic activities from sewage effluent and suggest co-existence of both types of activities from chemical mixtures in environmental samples.

TL;DR: The modelling indicated that the most important determinand for estrogen exposure in the Ray was not season, but proximity to the Rodbourne effluent, and throughout the year the whole length of the Ray downstream of Rodbourne would be estrogenic, i.e. exceeding the 1 ng/L E2 equivalent threshold for endocrine disruption.
