The paper presents a novel methodology (RICH, Ranking and Identification of Chemical Hazards) for ranking and identification of xenobiotic organic compounds of environmental concern in stormwater discharged to surface water. The RICH method is illustrated as a funnel fitted with different filters that sort out problematic and hazardous compounds based on inherent physico-chemical and biological...

conclusions further investigations are needed about favorable composition of unsaturated fatty acids and flavonoid content of leaves of s. paradoxa. in addition, due to high phenolic content of the leaves, s. paradoxa is a promising source of natural antioxidants and may play good antidiabetic activity. results the amount of total phenolic compounds was higher in leaves than roots. besides, roo...

New chlorine-containing furanones were tested for the presence of antibacterial activity and also for genotoxicity in Ames test. It has been established that the tested compounds had antibacterial properties. Antibacterial activities of all four compounds differed in rich broth and minimal glucose media. While in rich broth the minimal inhibitory concentration (MIC) of the compounds varied from...

pomegranate (punica granatum l.) is an important iranian-native fruit, whose many varieties are cultivated. fruits are widely consumed fresh and in processed forms as juice, jams and etc. pomegranate peel, as a by-product of the commercial juice industry, is a rich source of bioactive compounds. this research has been done to evaluate and compare physical characteristics, total phenolics, total...
