The aim of this study was to analyze changes in the content of selected polycyclic aromatic hydrocarbons (PAHs) in urban soils fertilized with municipal sewage sludge. The factors in the experiment were three lawns along the main roads in Bialystok (in Popieluszki, Hetmanska and Raginisa Strs.), doses of sewage sludge (0 – control; 75 and 150 Mg/ha) and two years of study (2011 and 2012). The s...

Efforts have been made in this study to stabilize the sewage sludge mixed with sugarcane trash in four different proportions: 20% (T(1)); 40% (T(2)); 60% (T(3)) and 80% (T(4)), under laboratory conditions using epigeic earthworm (Oligochaeta) Eisenia fetida. The composting potential of worm was also evaluated in 100% sewage sludge treatment (T(5)). The changes in chemical properties of substrat...

They will eventually end-up and accumulate in household or industrial sewage. Due to their high foaming capabilities, which can cause numerous problems in sewage treatment facilities as well as direct t...

The diversity of microbiota in waste waters has not been thoroughly examined, despite the potential impact of microbes on effluent quality. Wastewater microbial communities harbor pathogenic bacteria, viruses, and parasites. To study microbial communities in domestic sewage outfalls, 454 pyrosequencing technology was used to investigate the composition of microbial communities associated with m...

Single extractions with distilled water and diethylene-triamine-pentaacetic acid (DTPA), and a sequential extraction procedure were conducted in this study to determine the chemical speciation of Cd, Cr, Cu, Ni, Pb and Zn in four municipal sewage sludges and subsequently evaluate the phytotoxicity of the metals by a seed germination test of Chinese cabbage (Brassica chinensis L.). Analytical re...

The consumption of crops fertilized with human waste represents a potential route of exposure to antibiotic-resistant fecal bacteria. The present study evaluated the abundance of bacteria and antibiotic resistance genes by using both culture-dependent and molecular methods. Various vegetables (lettuce, carrots, radish, and tomatoes) were sown into field plots fertilized inorganically or with cl...

(Hydro)thermal treatments of sewage sludge is a promising option that can simultaneously target safe waste disposal, energy recovery, and nutrient recovery/recycling. The speciation of phosphorus (P) in sludge is of great relevance to P reclamation/recycling and soil application of sludge-derived products, thus it is critical to understand the effects of different treatment techniques and condi...

The molecular structure and transferability of Tn1546 in 143 vancomycin-resistant Enterococcus faecium (VREF) isolates obtained from patients (n = 49), surface water (n = 28), and urban and hospital sewage (n = 66) in Tehran, Iran, were investigated. Molecular characterization of Tn1546 elements in vanA VREF was performed using a combination of restriction fragment length polymorphism analysis ...

This study provides new information on the response of the immune system of Mytilus edulis exposed to untreated and treated sewage, linking immune response to ecologically relevant endpoints, such as disease resistance. Our goal was to assess the potential effects of sewage on the immune system (phagocytic activity and production of cytotoxic metabolites, disease resistance) and gills (light mi...
