Resumen
Abstract Severn Sound continues to exhibit signs of eutrophication despite initial identification of the problem in 1969 and the construction of several sewage treatment plants since then. In general, improvements in trophic state indicators have been marginal, suggesting that the sewage treatment plants have had limited success in controlling phosphorus concentrations. These discharges likely contributed to the increased total phosphorus levels and consequently the higher phytoplankton densities of the nearshore waters. Phytoplankton biovolumes were on average one order of magnitude higher th

Resumen
To evaluate the distribution of faecal material in Port Phillip Bay, surface sediments from sites throughout the bay and inflowing water courses were analysed for fatty acids and sterols. Water samples were also collected to identify possible sources of faecal contamination. Bay sediments had total fatty acid concentrations between 4 and 183 µg g–1 (dry weight) and total sterol concentrations between 0.6 and 39.2 µg g–1. Creek sediments contained more sterols, ranging from 22.8–148 µg g–1. These lipid distributions suggest that the bulk of the labile organic matter derives from marine microalg

Resumen
Abstract Estrogens are hormones responsible for growth and reproduction. They are naturally synthesized by animals and humans alike. Xenoestrogens are identical to natural hormones, but they are man-made and used as oral contraceptives. Xenoestrogens are a specific group of drugs found in domestic wastewater and some environmental matrices. These compounds remain after conventional sewage treatment and, consequently, affect both the environment and non-target aquatic organisms. In this study, we used the Delft3D hydrodynamic model to estimate the amount of both natural and synthetic estrogens

Resumen
There are potentially many thousands of municipally derived contaminants of emerging concern (CECs) present in discharged wastewaters that may cause adverse effects in receiving aquatic environments. Wastewater authorities, therefore, may face the momentous task of investigating these compounds with little or no prior CEC data for their sewage treatment plants (STPs). Such is the case for the Cleveland Bay Sewage Treatment Plant (CBSTP). To evaluate the potential environmental risk posed by municipal CECs, it is first necessary to understand which CECs are present in discharging wastewater, ho

We investigate nutrient trading for point and non-point sources for the Bay Restoration Fund in Maryland. We demonstrate how to use the proceeds from the tax revenue to mimic a market by trading high-cost upgrades of sewage treatment plants for low-cost winter cover crops. Under an optimistic assumption about costs for non-point sources and naïve assumptions about the lag from planting cover crops to changes in nitrogen load, we calculate that 100 percent of abatement could be achieved at 56 percent of total costs, while in a pessimistic scenario, 100 percent of abatement could be could be ach

Resumen
SynopsisThe paper summarises and briefly discusses published and unpublished data relating to the physicochemical characteristics of the sediments and the occurrence and distribution of the intertidal macrobenthos of paniculate shores in the Firth of Forth. In general, the shores described are poor faunistically and in some areas this results partly from the influence of waste water discharges. Detailed information is available for only a limited number of the numerous beaches in the Firth of Forth. In consequence, this paper focusses attention on the results of a long term study of four beach

Resumen
The coastal area of Piraeus is an environmentally aggravated region since many decades due to persistent pollution sources as the international port of Piraeus, a coastal fertilizers plant, the Athens sewage outfall and the industrial zone of Eleusis Bay. Recent sediment samples from the seabed of NW Salamina strait (upper Saronikos Gulf) were collected and analyzed for radionuclides and heavy metals composition. Measurements of 22 samples were performed including gralunometrical analyses using wet sieving treatment, radiological measurements using high resolution gamma-ray spectrometry and de

Resumen
In numerous studies of estuaries of the West Coast of the United States, we have recovered C.perfringens, total and fecal coliforms, and fecal streptococci from shellfish, sediments and water. In some areas closed to shellfish harvest and known to be subject to fecal contamination, C.perfrinqens were recovered regularly from shellfish and sediments. For example, in one estuary, prior to sampling, a local sewage treatment plant (STP) with a design capacity of 1 million gallons per day (MGD) was receiving high flows of raw sewage of 3.02 MGD. This resulted in an overflow or bypass of raw sewage

Resumen
Tolo Harbour is an almost land-locked waterbody with only one narrow marine inlet to the open sea at Mirs Bay in the Eastern Waters of Hong Kong. Due to its enclosed nature, the waste assimilative capacity is very limited. Besides, it receives substantial pollutant loads from the two sewage treatment plants in the Tolo catchment, livestock rearing industry and other industrial discharges. The building-up of the organic matter and nutrients in the Harbour has caused an increasing occurence of red tides in the past decade. This paper describes the trophic status of the Tolo Harbour based on the

Resumen
AbstractAdmiralty Bay on the King George Island hosts the Brazilian, Polish and Peruvian research stations as well as the American and Ecuadorian field stations. Human activities in this region require the use of fossil fuels as an energy source, thereby placing the region at risk of hydrocarbon contamination. Hydrocarbon monitoring was conducted on water and sediment samples from the bay over 15 years. Fluorescence spectroscopy was used for the analysis of total polycyclic aromatic hydrocarbons (PAHs) in seawater samples and gas chromatography with flame ionization and/or mass spectrometric d

Resumen
The James River has its head waters in the Allegheny Mountains and flows generally southeasterly to Hampton Roads, Chesapeake Bay and thence to the Atlantic Ocean. Below Richmond, Virginia, the river is tidal with the channel meandering through the coastal plains. Below Hopewell it widens to a broad estuary, with a deep navigable channel bordered by tide marshes. The upper estuary, between Richmond and Hopewell, is heavily used for water supply, recreation, and industrial development. The water entering the estuary a few miles upstream of Richmond is of good quality. However, as one reaches Ri

Resumen
Marmaris is a tourist city on the South-west Coast of Turkey. A sewage disposal project for Marmaris with an estimated population of 39,000 (excluding the temporary tourist population) for the year 2012, was completed in 1982. The sewage disposal system consisted of wastewater collection, treatment and deep sea discharge. The length of discharge pipe was determined as 520 m and a diffuser was placed 20 m below the sea level, so that the total coliform concentration at the protection zone boundary could be less than 1000/100 ml.

Resumen
Changes in benthic communities in Port Phillip Bay, Australia, were assessed over a 25- year period by comparing an intense bay-wide survey carried out in the early 1970s, a 3-year study in the mid 1970s, a limited survey in the early 1990s, and a resurvey in the mid 1990s. A major division of benthic communities into those on deeper muddy sediments and those on marginal sandy sediments persisted was less well defined (by ordination methods) in the 1990s than in the 1970s. The densities of individuals and species declined significantly, but absolute numbers of taxa did not change noticeably. N

Two endemic strains of the marine microalgal species Phaeodactylum tricornutum (designated B2 and B4), previously isolated from a sewage outfall site in St Andrews Bay, Scotland, were cultured in 20-litre mini-ponds to determine their ability to remove ammonium and orthophosphate from wastewater diluted with seawater. These strains had been selected from 102 species for optimal nutrient removal and culture dominance in both batch and continuous culture on wastewater under controlled environmental conditions. Wastewater (primary sewage effluent) was diluted 1:1 with sterile seawater and continu
