Environments polluted by direct discharges of effluents from antibiotic manufacturing are important reservoirs for antibiotic resistance genes (ARGs), which could potentially be transferred to human pathogens. However, our knowledge about the identity and diversity of ARGs in such polluted environments remains limited. We applied functional metagenomics to explore the resistome of two Croatian ...

In regions with a high infectious disease burden, concerns have been raised about the safety of iron supplementation because higher iron concentrations in the gut lumen may increase risk of enteropathogen infection. The aim of this study was to investigate interactions of the enteropathogen Salmonella enterica ssp. enterica Typhimurium with intestinal cells under different iron concentrations e...

metals bioaccumulation in five organs of cirrhinus  mrigala , labeo  rohita and catla catla captured from three industrial and sewage polluted downstream sites (shahdera = b, sunder = c and balloki = d) were compared with a non-industrial upstream site (siphon = a) during high (post monsoon) and low (winter) flow seasons of river ravi. mean concentrations of metals were significantly higher in ...

BACKGROUND Bacterial peritonitis is a frequent complication during treatment of end-stage renal failure by continuous ambulatory peritoneal dialysis. Local host defence mechanisms including the secretion of proinflammatory cytokines by peritoneal macrophages are of particular importance in the pathogenesis of infectious complications. LPS-binding protein (LBP) and soluble CD14 (sCD14) are serum...

The assessment of the quality of carwash effluents has received scant attention as a potential source of public and environmental health hazard in South Africa as demonstrated by the lack of literature in this subject. The physicochemical quality and potential ramifications of carwash effluents on receiving waterbodies were investigated in this study. Grab effluent samples were collected from s...

Environmental preservation is one of the key strategies addressing sustainable development. An awareness of environmental problems and potential hazards caused by industrial waste waters has prompted many countries to limit the discharge of toxic effluents. Mycoremediation play important role in the treatment of pulp and paper mill effluents containing numerous toxic substances like hydrocarbon...

In the context of urban drainage, the protection of surface waters from the effects of wastewater discharges has assumed increasing importance. As a result of human activity, there is sometimes contamination of water resources due not only to the phenomenon of diffuse pollution, but also as a result of specific effluent discharges (such as those from different industries or farming and by some ...

Conventional wastewater treatment, primary and secondary treatment processes with simultaneous phosphorus precipitation, is the most common process combination used in Finnish wastewater treatment plants (WWTPs). It typically eliminates most of the organic load and phosphorus, as well as part of the enteric microorganisms present in raw wastewater. Municipal secondary effluents still contain so...

The removal of phosphorus and nitrogen compounds from biochemically treated wastewater effluents by alum flocculation and lime precipitation was investigated. Samples of secondary effluent were flocculated or precipitated in accord with conventional Jar Test procedures. The phosphorus removal was found to be highly pH dependent with an optimum pH of 5.57 ± 0.25. At this pH an alum dose of 250 m...

Most effluents from wastewater treatment works (WwTWs) contain estrogenic chemicals that include steroidal estrogens and xenoestrogens. We investigated the nature of mixtures of estrogenic contaminants taken up by two species of fish exposed to two WwTWs effluents. Sexually immature rainbow trout, Oncorhynchus mykiss, and sexually mature roach, Rutilus rutilus, were exposed to tap water, river ...
