Estimated inorganic nutrient inputs to the coastal waters of Jersey from catchment and waste water sources

Diffuse and concentrated nitrogen sewage pollution in island environments with differing treatment systems

“…The STW was built for a population of 57,000 and so continuous improvements have been required as the population has grown and environmental standards have changed 23 . Despite continued improvements, surveys have shown that St Aubin’s Bay continues to exhibit high levels of nutrient loading from effluent 24 , 25 . Trophic status reports carried out by the Centre for Research into Environmental Health (CREH) in 1997 suggest winter hyper-nutrification in St Aubin’s Bay; despite the predicted 2% to 21% reduction in chlorophyll concentration from nutrient removal by the Bellozanne STW 25 .…”

Catchment to Coast Systems – Managing Microbial Pollutants for Bathing and Shellfish Harvesting Waters

“…Both nutrient and microbial pollution have caused signifi cant problems and major international initiatives to control their impacts can be seen in the OSPAR Convention covering the north -east Atlantic area (OSPAR 2007 ) and international directives such as the EU Urban Waste Water Treatment Directive (Stapleton et al 2000 ) targeted at nutrient control in coastal waters. Regulation of bacterial pollution is a more recent development which has been largely driven by health concerns associated with bathing and shellfi sh harvesting waters (Council of the European Communities 1976 ; United States Environmental Protection Agency 1986 ; World Health Organization 2003 ).…”

Ecosystem analysis of the degrading Vembanad wetland ecosystem, the largest Ramsar site on the South West Coast of India — Measures for its sustainable management

“…To understand the ecological functioning of aquatic system, the study on biotic communities and their interaction is important as the composition and distribution of these communities are significant in controlling the health of the aquatic ecosystem. Growth of autotrophs is limited by nutrients such as nitrogen (N) and phosphorus (P) [12,13] and its excessive increase causing eutrophication [14,15,16,17,18,19,20]. So, achieving a detailed and systematic understanding of the ecosystem status of an estuary is significant, for the estuarine management and also essential for predicting the response of coastal ecosystem to the incessantly progressing anthropogenic stressors.…”
