The various dilution levels of treated tannery effluent (T.E.) (10, 25, 50 and 100%) and Cr6+ (0.5, 2.0, 5.0 and 10 ppm) were used in experiment to know their effect on seed germination, seedling growth, pigments and enzymes content in Black gram (Phaseolus mungo Roxb.). Chromium is known as the main toxic component of tannery effluent so its various concentration were given to know their effec...
BACKGROUND Substantial efforts have been made toward defining the dose threshold of continuous renal replacement therapy (CRRT) associated with improved survival in critically ill patients with acute kidney injury. Published studies have used prescribed effluent rates, expressed as total effluent volume (TEV) per weight and unit time (mL/kg/h), as a surrogate for dose. The purpose of this study...
BACKGROUND A 5-day fathead minnow (FHM) spawning assay is used by industry to monitor pulp mill effluent quality, with some mill effluents capable of completely inhibiting spawning. The purpose of this report is to characterize the effect of an inhibitory effluent on egg and milt production in FHM. METHODS Eight tanks were treated with an inhibitory effluent while eight were kept with clean w...
Static, short-term, acute toxicity tests were performed over a period of 96 hrs using different concentrations of influent and effluent of textile industry waste water with the objective of evaluating their acute toxicity on fresh water fish, Cyprinus carpio (common carp). The LC50 24, 48, 72 and 96 hr of influent and effluent were 25.9, 21.10, 15.66, 11.11% (v/v) and 63.18, 54.89, 48.62, 36.04...
Ammonium stripping has gained increasing interest for nitrogen recovery in anaerobically digested effluents. However, the stripped effluents often still do not meet discharge standards, having high pH and residual pollutants. Constructed wetlands (CWs) are an easy to operate ecosystem and have a long history of application in treatment of wastewaters with extreme pH, such as acid mine drainage....
The common bully (Gobiomorphus cotidianus), a small-bodied New Zealand native fish species, was used to monitor population impacts of multiple effluents in the Tarawera River, New Zealand. In an initial survey, the absence of reproductive development at the expected spawning time for common bullywas observed in a population downstream of effluent discharges. Subsequently, we examined the hypoth...
Metabolite analysis of peritoneal dialysis (PD) effluent may provide information regarding onset and progression of complications associated with prolonged PD therapy. In this context, the nuclear magnetic resonance detectable small metabolites of PD effluent samples were characterised using high-resolution (1) H and (1) H-(13) C NMR spectroscopy. The various spectra were recorded (at 800 MHz p...
The effect of seven rates viz. 0 (control), 5, 10 25, 50, 75 and 100 ml/Kg of treated distillery effluent on the physico-chemical properties of soils was studied under natural environment in pot experiment. The characteristics of the soil were determined before and after 12 weeks of effluent irrigation. The results revealed that the 100% concentration of distillery effluent decreased BD (5.63%)...
Effluent discharge from septic tanks is affecting the environment in developing countries. The most challenging issue facing these countries is the cost of inadequate sanitation, which includes significant economic, social, and environmental burdens. Although most sanitation facilities are evaluated based on their immediate costs and benefits, their long-term performance should also be investig...
BACKGROUND Using treated wastewater in agriculture irrigation could be a realistic solution for the shortage of fresh water in Iran, however, it is associated with environmental and health threats; therefore, effluent quality assessment is quite necessary before use. The present study aimed to evaluate the physicochemical and microbial quality of Shiraz wastewater treatment plant effluent for b...
