Ecological Risk Assessment of Heavy Metals in Sediment of Fe lent Stream, Sakarya River Basin, Turkey
(Zoological Soc Pakistan, 2013)
Many indices have been developed to evaluate the environmental risks of heavy metals in sediments. In the present study, two of these indices were used to determine the sediment quality of a polluted freshwater ecosystem: ...

(Elsevier Science BV, 1997)
An improved HPLC procedure for quantitative determination of the alkannin derivative naphthaquinones, beta,beta-dimethylacrylalkannin (I), teracrylalkannin (II) and isovalerylalkannin (III)+alpha-methyl-n-butylalkannin ...
Electrochemical treatment of aqueous oxalic acid solution by using solid polymer electrolyte (SPE) reactor
(Elsevier Science Sa, 2009)
In this study, the feasibility of electrochemical oxidation of the aqueous oxalic acid solution has been investigated in an electrochemical reactor with SPE and simultaneous hydrogen production has been observed. Experiments ...

In the present study, water, sediment, diatom (epipelic), plant (Lemna trisulca), benthos (Gammarus sp. and Hirudo sp.) and fish samples (Alburnus escherichii and Gobio sakaryaensis) were collected from Felent Stream ...
Phenol removal through chemical oxidation using Fenton reagent
(Wiley-V C H Verlag GMBH, 2007)
In this study, phenol, aromatic, and non-biodegradable organic matter were investigated and found to be removed from the model solution through chemical oxidation using Fenton reagent. The effects of the initial phenol ...
Assessment of environmental effects of the coal used in the Seyitomer thermal power plant (Turkey) on white willow
(Taylor & Francis Inc, 2006)
Thermal power plants increase local pollution through SO x , NO x , volatile organic compounds (VOCs), and oils containing primarily particulates (including heavy metals) and increase global pollution through CO2 , the ...
