Fiberboards are used in a variety of applications that can be for interior as well exterior. However, their production involves the consumption virgin wood fibers and use formaldehyde-based adhesives, with consequent impact on environment health. The removal these adhesives results significant loss physico-mechanical properties. To confront major problems, wheat straw, an agricultural waste, ra...
The effect of Palangan fish farms on water quality of Sirvan River was investigated using physicochemical and biological indicators from January 2015 to June 2015. Five stations were determined including 1) before the fish farm 2) after the fish farm effluent 3) sub-branch 4) 100 meter after fish farm effluent and 5) 1000 meters after fish farm effluent. EC showed significant differences in dif...
Irrigation with reclaimed wastewater (effluent) is one way to dispose this waste particularly in water scarce arid and semi-arid areas. Secondary effluent used for irrigation contains considerable amounts of N, both in inorganic and organic forms. Whereas attention was given to transformations of inorganic N originated from effluent, little is known regarding the fate of the organic N in efflue...
The aim of this study was to determine if endothelial cells in the heart release substances into the coronary perfusion medium that modify the contractility of myocardial cells. To assay the effects on the contractility of cardiac muscle of fluid that has passed through the coronary vasculature, a new method has been developed based on the cascade principle used to study vascular smooth muscle ...
Attenuation of the pesticide fipronil and its major degradates was determined during conventional wastewater treatment and wetland treatment. Analysis of flow-weighted composite samples by liquid and gas chromatography-tandem mass spectrometry showed fipronil occurrence at 12-31 ng/L in raw sewage, primary effluent, secondary effluent, chlorinated effluent, and wetland effluent. Mean daily load...
In acute toxicity (96 hr) experiment the fingerlings of freshwater fish Labeo rohita was exposed to tannery, electroplating and textile mill effluents. The LC0 and LC50 concentrations were 15% and 20% for tannery effluents, 3% and 6% for electroplating effluents and 18% and 22% for textile mill effluents respectively. It was found that, electroplating effluent was more toxic than tannery and te...
Microalgae lipid feedstock preparation cost was an important factor in increasing biodiesel fuel hikes. This study was conducted with the concept of implementing an effluent wastewater as lipid production medium for microalgae cultivation. In our study textile dyeing industry effluent was taken as a lipid production medium for Neochloris sp. cultivation. The changes in physicochemical analysis ...
The presence of effluent-derived compounds with low odor thresholds can compromise the aesthetics of drinking water. The potent odorants 2,4,6-trichloroanisole and geosmin dominated the profile of odorous compounds in wastewater effluent with concentrations up to 2 orders of magnitude above their threshold values. Additional odorous compounds (e.g., vanillin, methylnaphthalenes, 2-pyrrolidone) ...
The effect of electroplating factory effluent at different dilutions (such as 0.0, 0.10, 0.25, 0.50, 1.00, 1.50, 2.00, 2.50, 3.00, 3.50 and 4.00%) on the germination, growth and nutrient concentration in Tomato (Lycopersicum esculentum) and Egg-plant (Solanum melongena) was studied in an urban soil of Aligarh District of Uttar Pradesh. The results indicated that the germination of both the plan...
