background and purpose: disposing sludge from industrial wastewater treatment plants (iwwtps) is a serious issue because it can affect human and animals health, and also environmental quality. in this study, sludge from an iwwtp was analyzed regarding its physicochemical characteristics and disposal options. materials and methods: grab sampling was used to collect 12 sludge samples biweekly (ma...

Dried blood spot real-time polymerase chain reaction assays to screen newborns for congenital cytomegalovirus infection.rial load in children and adolescents with pneumococcal pneumonia and empyema. cation of pneumococcal serotypes from culture-negative clinical specimens by novel r...
The influence of manure and composts on the leaching of heavy metals from soil was evaluated in a model lysimeter experiment under controlled conditions. Soil samples were collected from experimental fields, from 0- to 90-cm layers retaining the layout of the soil profile layers, after the second crop rotation cycle with the following plant species: potatoes, spring barley, winter rapeseed, and...
Rats were fed, from weaning through 11 weeks of age, dried leaf tissue of corn plants grown on soil amended with regular NPK fertilizer (150-22-62), with 33.6 ad 67.2 metric ton/ha of sewage sludge or with salts of cadmium (10kg/ha), lead (25kg/ha), and/or zinc (50kg/ha). A very high proportion of the cadmium (cd) consumed was eliminated in feces. Only in rats fed diets containing leaf tissue f...
Shochu wastewater (SW; alcoholic distillery wastewater) contains large amounts of organic compounds (25,000 - 60,000 COD mg/L), nitrogen (1,000 - 6,000 T-N mg/L), and phosphorus (500 - 1,000 T-P mg/L). Despite its high nutrient content, SW is highly perishable, which limits its utilization for animal feed and fertilizer. Therefore, SW is mainly treated by methane fermentation. On the other hand...
High temperature metallurgical slag (temperature, >1450?C) and high moisture sludge (moisture content, >80 wt.%) are common wastes with huge outputs. Many problems, such as cost, low level of harmlessness, efficiency, encountered in current treatment methods. If these can be recycled, they valuable secondary resources. Therefore, using the drum apparatuses to treat two kinds is proposed. ...
Activated sludges are an inoculum source commonly used in biodegradation studies, as wastewater treatment facilities constitute an entry point to the environment for many chemicals. In this paper, the main issues relating to the use of activated sludge in biodegradability tests are presented. Special attention is also devoted to discussing the factors affecting both the activity of the microbia...
