Given the fact that pesticides exist in the aquatic environment at very low concentrations, it is clear that their analysis require expensive analytical techniques. Water authorities in Turkey are in need of assessing the likelihood of pesticide occurrence in groundwater in order to identify minimum number of pesticides that would be included in monitoring programs. To this purpose, the pesticides used in Turkey are ranked and those having higher leaching potentials are identified using pesticide screening leaching indexes. A total of 15 indexes (AF, AFR/AFT, Hamaker's RF, Briggs's RF, LPI, VI, LIX, GUS, Hornsby, LEACH, MLEACH, PLP, GWCP, LIN and GU) was adopted and leaching potentials of 157 pesticides used in Turkey were estimated. Because each index is based on different pesticide/soil characteristics, each produced a different ranking. In order to emphasize variation in rankings and bring out a strong pattern, the statistical technique of Principal Component Analysis was used and a new composite index named as "YASGEP-P" was developed, the most relevant components (indices) were identified and the corresponding factor scores were calculated. This new index came out as a composite of GUS, LIX, MLEACH, LIN, Briggs's RF, Hamaker's RF, PLP and AFR indices. It was seen that all these indices except AFR are almost equally dominant and increase the value of YASGEP-P index, whereas AFR is also dominant but causes a decrease in YASGEP-P index value. The new index developed tends to discriminate between the relatively more soluble/less sorbable and more sorbable/less soluble pesticides. With the use of this composite index, the pesticides used in Turkey were sorted from the most leachable to least leachable and the priority pesticides to be monitored in the groundwaters were identified.

Degradation of decabromodiphenyl ether (BDE-209) in microcosms mimicking sediment environment subjected to comparative bioremediation strategies
Demirtepe, Hale; İmamoğlu, İpek (Elsevier BV, 2019-03-01)
The aim of this study was to examine bioremediation strategies for BDE-209 contaminated sediments. Sediment microcosms were established to observe anaerobic debromination of BDE-209 under conditions representing three bioremediadon strategies: biostimulation, bioaugmentation and natural attenuation. To simulate biostimulation, a defined mineral medium containing both a carbon source (sodium formate) and electron donor (ethanol) was added into sediments. Bioaugmentation was established by enrichment of the s...
A COMPARATIVE-EVALUATION OF DIFFERENT APPROACHES FOR ASSESSING SOIL ACIDIFICATION IMPACTS
SOYUPAK, S; KILIC, B; MUKHALLALATI, L; YURTERI, C (Informa UK Limited, 1993-01-01)
Long-term impacts of acidic depositions on soils can be predicted with coupled applications of acid deposition models and approaches to assess soil acidification. Soil acidification assessment can be achieved by using the following approaches: (i) Mechanistic modelling (ii) Experimental acid buffering capacity (ABC) method (iii) Qualitative evaluations The mechanistic modelling approach adopted in this study utilises predicted acid deposition rates and soil properties as well as dominant soil mechanisms inc...
Characterization of lead-resistant river isolate Enterococcus faecalis and assessment of its multiple metal and antibiotic resistance
Aktan, Yasin; Tan, Sema; İçgen, Bülent (Springer Science and Business Media LLC, 2013-06-01)
Contamination of surface waters has a direct impact on the public health of entire communities. Microorganisms inhabiting contaminated surface waters have developed mechanisms of coping with a variety of toxic metals and drugs. Investigations were carried out to isolate and identify lead-resistant bacteria from the river KA +/- zA +/- lA +/- rmak along the city of KA +/- rA +/- kkale, Turkey. Of the 33 lead-resistant isolates, one isolate with a minimal inhibitory concentration of 1,200 mg L-1 was isolated ...
Diversity and community analysis of ammonia oxidizing bacteria in a streambed surrounding an artificial dam
Murdoch, Robert Waller; Staniec, Andria Costello (Elsevier BV, 2013-09-30)
The degree to which small natural dams affect the native bacterial nitrogen cycling community was explored by molecular methods. The identities and relative abundances of ammonia oxidizing bacteria in the sediment surrounding an artificial dam both at the surface and in the hyporheic zone were characterized. Analyses were performed using tRFLP of the conserved amoA gene using a semi-nested degenerate PCR approach. Additionally, an amoA gene library was constructed to characterize the most dominant sediment ...
A Laboratory Column Investigation for the Treatment of Cr(VI) with Zero-Valent Iron
Uyusur, Burcu; Ünlü, Kahraman (Mary Ann Liebert Inc, 2009-02-01)
Permeable reactive barrier (PRB) technology is commonly placed in the list of options for groundwater remediation at hazardous waste sites, where Cr(VI) treatment in groundwater has been a concern more than any other inorganic contaminants. The objective of this study was to investigate the effectiveness and longevity of Cr(VI) removal with zero-valent iron based PRBs. The main focus was on two parameters affecting the performance of Cr(VI) removal with PRBs: (1) amount of reactive media and (2) groundwater...
