Phytoremediation of Dairy Effluent by Constructed Wetland Technology Using Wetland Macrophytes
One of the burning problems of our industrial society is the high consumption of water and the high demand for clean drinking water. Numerous approaches have been taken to reduce water consumption, but in the long run it seems only possible to recycle wastewater into high quality water. In this study, an attempt was made to compare the efficiency of aquatic macrophytes like Typha sp., Eichhorni...
متن کاملEvaluation of the toxic effect of peracetic acid on grass carp (Ctenopharyngodon idella) juveniles.
OBJECTIVES The aim of present study was to evaluate the effect of peracetic acid (PAA) on haematotological and biochemical indices, antioxidant status, micronucleus induction and histopathological alterations of liver and gill in grass carp. METHODS Grass carp (Ctenopharyngodon idella) juveniles were exposed to therapeutic concentrations (1, and 3 mg x l(-1)) of PAA for a period of 10 days. S...
متن کاملConstructed wetland systems vegetated with different plants applied to the treatment of tannery wastewater.
Wastewaters from leather processing are very complex and lead to water pollution if discharged untreated, especially due to its high organic loading. In this study the survival of different plant species in subsurface horizontal flow constructed wetlands receiving tannery wastewater was investigated. Five pilot units were vegetated with Canna indica, Typha latifolia, Phragmites australis, Steno...
متن کاملAcute toxicity of Nuvan, an organophosphate to freshwater fish Ctenopharyngodon idella and its effect on oxygen consumption.
The acute toxicity of Nuvan to the grass carp Ctenopharyngodon idella was determined using static and continuous flow through system for 24, 48, 72 and 96 hr. The median lethal concentration (LC50) values were 13.1, 10.9, 9.8 and 6.5 mg l(-1) respectively in static system and 10.7, 9.5, 8.0 and 7.5 mg l(-1) respectively in continuous flow through system. A reduction in oxygen consumption is obs...
متن کاملEvaluation of blood characteristics of grass carp (Ctenopharyngodon idella) after exposure to organophosphate, Diazinon
The effect of different sublethal concentrations of diazinon at 1, 2 and 4 mg/L on some hematological and biochemical parameters of grass carp (Ctenopharyngodon idella) weighing 850±155g was studied after 1, 7, 15, 30 and 45 days post exposure to the toxicant as a bath for 12 hours at 18-22 C. In one day exposure fish to the toxicant, the values of neutrophiles exposed to 2 and 4mg/L were signi...
