PHENOLIC COMPOUNDS IN SURFACE WATER
"... Abstract—The presence of phenols in a stream is undesired because of their strong action, their toxicity to fish and unpleasant tastes and odours produced when water containing phenols is chlorinated. The phenolic compounds in the water environment may have a natural, industrial, domestic or agri-cu ..."

Determination of Phenolic Compounds in wines
, 2011
"... Wine contains natural antioxidants such as phenolic compounds also known as bioactive compounds. Samples of commercially available Greek wines were analyzed in order to determine this phenolic content. For the analysis, Reversed Phase-High Performance Liquid Chromatography (RP-HPLC) coupled with a m ..."

Phenolic compounds and antioxidant activities of
"... In this study different solvent fractions (n-hexane, ethyl acetate, chloroform, butanol and aqueous) of the methanol extract of Rumex hastatus(RH) leaves were evaluated for antioxidant activities. The ethyl acetate fraction possessed high amount of total polyphenolics (106.3±3.93 mg GAE/g extract) w ..."

heavy metals are defined as that group of elements that have specific weights higher than about 5g/cm3. a number of them (co, Fe, Mn, Mo, ni, zn, cu) are essential micronutrients and are required for normal growth and take part in redox reactions, electron trans-fers and other important metabolic processes in plants. Metals which are considered nonessential (pb, cd, cr, Hg etc.) are potentially highly toxic for plants [1- 3]. large areas of land are contaminated with heavy metals (the main group of inorganic contaminants) resulting from urban activities, agricultural practices and indus-try [4, 5]. Excessive concentrations of trace elements (cd, co, cr, hg, Mn, ni, pb and zn) are toxic and lead to growth inhibition, decrease in biomass and death of the plant [6]. Heavy metals inhibit physiological pro-cesses such as respiration, photosynthesis, cell elonga-tion, plant-water relationship, n-metabolism and min-eral nutrition [7].

Hematin-Catalyzed Polymerization of Phenol Compounds
, 1999
"... ABSTRACT: The oxidative dehydrogenation of phenol compounds, as well as polymer formation from these monomers, was studied by UV-vis and Mössbauer spectroscopy using a novel biological catalyst hematin. The mechanism of the polymerization reaction was also followed in various pH environments. Pheno ..."
