The paper deals with effects of liming and different doses of municipal sewage sludge (5, 10, and 15 % of soil mass) on copper speciation in soil. In all samples, pH was determined together with total copper concentration, which was measured with the ICP-AES method. Concentration of copper chemical fractions was determined using the seven-step procedure of Zeien and Brümmer. In the soil treated...

Here, we report the draft genome sequence of the nitrate- and phosphate-accumulating Bacillus sp. strain MCC0008, isolated from a consortium enriched from municipal sewage in nitrate broth (HiMedia M439). The total size of the genome is 5,609,456 bp, with a G+C content of 35.1%.

Clostridium paradoxum strain JW-YL-7 is a moderately thermophilic anaerobic alkaliphile isolated from the municipal sewage treatment plant in Athens, GA. We report the near-complete genome sequence of C. paradoxum strain JW-YL-7 obtained by using PacBio DNA sequencing and Pilon for sequence assembly refinement with Illumina data.

Megacities concentrate large amounts of people, absorb a large quantity of resources and generate vast amounts of waste and sewage, thereby contributing considerably to the use of the environment as a sink. The quantity of resources consumed and urban residues produced per capita tend to rise steadily with increased per capita income. Proper management of municipal solid waste is critical to th...

BACKGROUND Workers exposed to sewage may have an increased risk of infection by Helicobacter pylori and hepatitis E virus (HEV). AIMS To assess the prevalence of clinical hepatitis E (HE) and peptic ulcer disease as well as the seroprevalence of antibodies to H pylori and HEV in workers with and without sewage exposure and to look for symptoms due to exposure to endotoxin. METHODS In the fi...

sludge production is an avoidable problem arising from the treatment of wastewater. the sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. on the other hand, this sludge has benefits for plants and soils. thereupon, land application of sludge has received...

The study was focused on two goals: (i) the confirmation of the existence of a general relation between the content of polycyclic aromatic hydrocarbons (PAHs) in sewage sludge and in plants growing in it, regardless of the type and content of sewage sludge, and (ii) if so, the answer to the question whether the uptake of PAHs by plants depends on their type. To realize the set aims, the content...

Amongst the technologies available, the upflow anaerobic sludge blanket (UASB) process has been one of the most widely applied methods for municipal wastewater treatment especially in countries of warm climatic conditions like India. However, past about one decade has witnessed rapid decline in the UASB popularity and its implementation. There has been criticism from various sections on the per...
