Evaluation of fecal pollution in coastal Italian waters
نویسندگان
چکیده
Direct detection of fecal coliforms as indicators of fecal pollution may assess water quality more accurately than culture methods. An irnmunochemical technique involving the use of specific antibodies was applied in addition to plate counts to evaluate Escherichia coliin seawater samples from different coastal areas in southern Italy. The immunofluorescent method showed high specificity for enteropathogenic E. col; although the presence of a threshold value of 102 ce11/100 m1 sets a lower hmit to the possibility of applying this method. It proved to be a rapid screening method to distinguish between polluted and unpolluted areas.

Monitoring of fecal pollution in coastal waters by use of rapid enzymatic techniques.
Enzyme assays for 4-methylumbelliferyl-beta-D-galactopyranosidase and 4-methylumbelliferyl-beta-D-glucuronidase activities were used for rapid detection (25 min) of fecal water pollution and to determine the impact of sewage discharge in coastal waters. Two coastal areas were investigated: (i) an estuary characterized by a high degree of contamination downstream of a discharge from a sewage tre...

Fecal microbial pollution of recreational and shellfishing waters is a major human health and economic issue. Microbial pollution sourced from stormwater runoff is especially widespread, and strongly associated with urbanization. However, non-point source nutrient pollution is also problematic, and may come from sources different from fecal-derived pollution (i.e. fertilization of farm fields, ...

Pollutant impacts to Cape Hatteras National Seashore from urban runoff and septic leachate.
The sandy barrier islands of Cape Hatteras National Seashore, USA, attract large seasonal influxes of tourists, and are host to numerous motels, rentals and second homes. To investigate the impacts of nearby urbanization on public trust waters, sampling was conducted in nine brackish water bodies within this coastal national park. A large tidal urban ditch delivered runoff-driven fecal-contamin...
متن کاملEvaluation and classification of trophic status in coastal waters of Homozgan province using trophic index Scale (Trixcs) and unscale (Untrixcs)
One of the most important issues in environmental management of coastal waters is the evaluation of Eutrophication. In this study, the trophic status of coastal waters of Hormozgan province was evaluated using Scale (TRIXCS) and Unscale (UNTRIXCS) trophic indices in 2012. The results showed that TRIXCS values were in the range of 3.6 to 5.9 (in the area 1 Mezo-Eutroph, areas 2 and 3 Mezotroph, ...
