BACKGROUND Few studies have evaluated predictors of childhood exposure to organochlorine pesticides (OCPs), a class of lipophilic persistent chemicals. OBJECTIVES Our goal was to identify predictors of serum OCP concentrations-hexachlorobenzene (HCB), β-hexachlorocyclohexane (β-HCH), and p,p-dichlorodiphenyldichloroethylene (p,p´-DDE)-among boys in Chapaevsk, Russia. METHODS Between 2003 an...
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...
micro flora of the effluents from a dairy factory in tehran(pegah dairy processing plant) were isolated and screened for their ability to reduce the organic matter content and cod of the effluents. 10 bacteria were selected due to reduction in cod content from the 4th to 6th day of incubation at 30 °c and ph =11. highest cod reduction were obtained by two isolates, bp3 and bp4, 70.7 % and 69....
Dairy waste, more than any other trade waste has long since attracted the attention of specialists in the field of waste water purification. Many experiments have been made with artificial waste water, made from milk or milk products. Dairy wastes provide an excellent nutrient medium for many types of bacteria and fungi and, contrary to opinions held at one time, are very amenable to aerobic bi...
The production of dairy products generates several environmental impacts, and life cycle assessment (LCA) is a useful methodology to quantify understand those impacts. In Brazil, some traditional have not yet been evaluated using the LCA methodology. Based on this gap, we conducted cradle-to-gate six from plant in Minas Gerais, Brazil. We also performed two sensitivity analyses. first analysis ...
DEVELOPMENT OF IMPROVED TECHNOLOGY UNDER OPERATION FOR TREATING WASTEWATER WITH BUTTERMILK USING EBM
This research is to develop an improved technology in a wastewater treatment facility containing fermented buttermilk under operate of dairy product factory. Wastewater with high concentrations difficult treat. Through new Enzyme Biofilm Method(EBM), we made improvements and demonstrated appropriate operation. After two tests, the improvement final stage, despite accepting all waste, has kept d...
