The present study included an evaluation of the content of 16 PAH in sewage sludge produced in 15 sewage treatment plants in southeastern Poland. Besides determining PAH content, the influence of the amount and origin of the sewage purified in the PAH content was also evaluated. Possible PAH sources in sewage were also evaluated by the calculations of the mutual relations. The results obtained ...

Great differences in capability to detect bacteriophages from urban sewage of the area of Barcelona existed among 115 strains of Bacteroides fragilis. The capability of six of the strains to detect phages in a variety of feces and wastewater was studied. Strains HSP40 and RYC4023 detected similar numbers of phages in urban sewage and did not detect phages in animal feces. The other four strains...

The Nuclear Regulatory Commission (NRC) announced the availability of three new documents concerning radioactive materials in sewage sludge and ash from publicly owned treatment works (POTW). One of the documents is a report presenting the results of a volunteer survey of sewage sludge and ash samples provided by 313 POTWs. The second document is a dose modeling document, using multiple exposur...

The disposal and the treatment of sewage sludge is an expensive and environmentally complex problem. In this work, a lipopeptide biosurfactant extracted from corn steep liquor was used as ecofriendly and cost-competitive alternative for the mobilization and bioremediation of fluorene in sewage sludge. Results have demonstrated that this biosurfactant has the capability to mobilize fluorene to t...

Samples of sewage from treatment plants at the "G. Martino" University Hospital of Messina (AOU) and that of Messina City Council were analysed to detect the hepatits E virus. Samples were taken on sewage entering and exiting the treatment plants on a monthly basis over a one-year period from both the hospital plant (24 samples) and the municipal plant (22 samples). All sewage samples were pret...

century. A sewage system created by Victorian engineers was a remarkable achievement that began the big clean-up. The now much cleaner river is once again home to many species alongside the seahorse: the young of marine species such as flounder and bass have been discovered in nursery sites up to 20 km inland. But the sewage system that has done so much to restore the river’s cleanliness still ...

Objectives—To further assess the presence of fatigue, symptoms of diarrhoea, and inflammation of airways among people working in sewage plants and the relation to airborne bacterial endotoxin at the workplace. Methods—34 Employees in sewage treatment plants and 35 controls were selected. They underwent a questionnaire investigation, and spirometry and airway responsiveness were measured. Measur...

In this work, the thermal behavior of rice husk, sewage sludge, and their blends during combustion processes was investigated by means of thermogravimetric analysis (TGA), and the slagging characteristics were studied through X-ray fluorescence (XRF) and melting temperature. The effects of the proportion of rice husk and sewage sludge blends on the combustion process, ignition and burnout chara...

The objective of the study was to determine the leachates toxicity from sewage sludge-amended soils (sandy and loamy). Samples originated from a plot experiment realized over a period of 29 months. Two types of soil were fertilized with sewage sludges at the dose of 3 % (90 t/ha). Soil samples were taken after 0, 7, 17, and 29 months from the application of sewage sludges. Leachates were obtain...

Phytoremediation is the technique based on the use of plants to remediate sites contaminated with organic and inorganic pollutants. This technology is rapidly growing as is helpful to growing industries. Colocasia esculenta is a tropical plant grown primarily for its edible corm and the root vegetables. It has many names like Taro and Eddoe. It is a wide spread emergent aquatic plant, generally...
