Aquatic fungi are common in various aqueous environments and play potentially crucial roles in nutrient and carbon cycling as well as interacting with other organisms. Species of Aspergillus are the most common fungi that occur in water. The present study was undertaken to elucidate the efficacy of two coagulants, aluminum sulfate and ferric chloride, used at different concentrations to treat drinking water, in removing Aspergillusflavus, as well as testing three different filtration media: sand, activated carbon, and ceramic granules, for their removal of fungi from water. The results revealed that both coagulants were effective in removing fungi and decreasing the turbidity of drinking water, and turbidity decreased with increasing coagulant concentration. Also, at the highest concentration of the coagulants, A. flavus was decreased by 99.6% in the treated water. Among ceramic granules, activated carbon, and sand used as media for water filtration, the sand and activated carbon filters were more effective in removing A.flavus than ceramic granules while simultaneously decreasing the turbidity levels in the test water samples. Post-treatment total organic carbon (TOC) and total nitrogen (TN) concentrations in the experimental water did not decrease; on the contrary, TN concentrations increased with the increasing dosage of coagulants. The filtration process had no effect in reducing TOC and TN in tested water. 相似文献

Feeding deltamethrin-contaminated grains to domestic poultry, such as quails may result in toxic effects in these birds. This study was done to investigate the effects of recommended doses of deltamethrin, sometimes used in grain storage silos, on Japanese quail (Coturnix japonica). Quails were fed grains contaminated with 0.25 and 0.50 mg deltamethrin per kg diet for 21 days and the effects on survival and blood biochemical parameters were studied. Plasma uric acid, creatinine levels, and creatinine phosphokinase activity in the blood were increased. Aspartate aminotransferase and lactate dehydrogenase activities and glucose levels significantly increased in birds treated with the high dose of deltamethrin. Alanine aminotransferase activity and albumin or cholesterol levels were not changed, and acetylcholinesterase and alkaline phosphatase activities, total protein and globulin in plasma were decreased. Administration of 0.25 mg/kg deltamethrin caused increased blood triglyceride levels, 0.50 mg/kg deltamethrin decreased triglyceride levels. 相似文献

Work-related accidents are considered as a major health problem worldwide. The aim of present study was to determine the epidemiological pattern of occupational accidents among workers insured by the Iranian Social Security Organization (ISSO) between 2001 and 2005.Subjects consisted of all workers and drivers who had a work-related accident during 2001–2005 and were registered in the Iranian Social Security Organization (ISSO) database according to the inspection reports. An ordinal logistic regression model (proportional odds regression model) was used to assess the concurrent effects of independent variables on accident outcomes.Overall, 86,437 work-related accidents were investigated. The accidents were more frequent in metal workplaces and electrical industries, respectively. More than half of the accidents were due to incautious activities. Workers’ age (age at the time of accident) (OR = 0.99, CI: 0.989–0.994), gender (OR = 1.3, CI: 1.191–1.683), marital status (OR = 1.25, CI: 1.143–1.675) as well as accident setting (OR = 1.88, CI: 1.728–1.975) had significant effect on accident outcomes. Pattern of occupational injuries in Iran was consistent with the global pattern for accident outcomes. 相似文献
