Samples of seawater and surface sediment were collected from seven locations around Halifax Harbour, Nova Scotia, Canada, and analyzed for the presence of the organic estrogenic contaminants, bisphenol A (BPA), 17β‐estradiol (E2), and 17α‐ethinylestradiol (EE2). Samples were extracted using solid phase extraction (seawater) or sonication (sediments), followed by fractionation on a two‐layer alumina/silica gel column prior to analysis by liquid chromatography–tandem mass spectrometry (LC‐MS/MS… 

Natural and Synthetic Estrogens in Wastewater Treatment Plant Effluent and the Coastal Ocean

A tandem mass spectrometry method capable of simultaneously quantifying free, conjugated, and halogenated estrogens at picomolar levels in wastewater effluent and coastal seawater is developed and found that synthetic estrogens and progestogens in commercial and pharmaceutical preparations exhibit significantly depleted 13C values compared to endogenous steroids.

Influence of poultry litter land application on the concentrations of estrogens in water and sediment within a watershed.

The quantitative analysis of the temporal and spatial distribution of the estrogens suggests the occasional elevation of estrogens in the watershed above the predicted-no-effect-concentrations to fish likely to be associated with litter disposal and rainfall events.

Endocrine disrupting chemicals in New Orleans surface waters and Mississippi Sound sediments.

Endocrine disrupting compounds (EDCs), represented by steroid hormones, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and bisphenol A have been determined in four sediment cores from the Gulf of Mexico, from New Orleans surface water, and from the influent and effluent of a New Orleans municipal sewage treatment plant.



Horizontal and Vertical Distribution of Estrogenic Activities in Sediments and Waters from Tokyo Bay, Japan

The relationship between salinity and estrogenic activity in water samples suggested that fresh water is one source of environmental estrogens in Tokyo Bay, and the high estrogenic activities as measured in water and sediment samples from Tokyo might be restricted to certain coastal areas.

In vivo bioassay‐guided fractionation of marine sediment extracts from the Southern California Bight, USA, for estrogenic activity

Results indicate that estrogen receptor-based assays may underestimate environmental estrogenic activity and estrogenic compounds other than classic natural and xenoestrogens may contribute to estrogenicActivity of sediments from the SCB.

Toxicity of Halifax Harbour Sediments: an Evaluation of the Microtox® Solid-Phase Test

Subtidal sediments were collected from 8 stations in Halifax Harbour, N.S., in July and August, 1992, to initiate a study of sediment toxicity and hazards near the proposed location of a sewage

Sediment bioassessment in Halifax Harbour

Halifax Harbour sediments contain heavy metals and organic contaminants. To assess the biological effects of these compounds in the sediment, seven sites spanning a range of known sediment types,
