The Effects of Some Pesticides on Human and Bovine Erythrocyte Carbonic Anhydrase Enzyme Activities in Vitro
(Marcel Dekker Inc., 1996) Çelik, I.; Çamaş, H.; Arslan, O.; Küfrevioǵlu, Ö.I.
The influence of Penncozeb [Mangan-zinc ethylenediamine-bisdithicarbamate], Dithane, [Manganese etylenebisdithiocarbamate], Cupravit [Cuper oksichloride]. Bayleton [1-(4- chlorophenoxy)-3.3-dimethyl-1-(1H-1.2.4-Thiazol-1-yl)-2.2-butanon], Baythroid [Cyano-(4 fluoro-3-phenoxyphenyl)-methyl-3-(2.2-dichloroethyl -2. 2 metyl - cyclopropancarboxylate], Mavrik [-cyano-3-phenoxybenzyl N-(2-chloro-trifluoro - p -tolyl], Talstar [2-methyl biphenyl-3-ylmethyl(z)-(IRS,3RS)-3-(2-chloro-3.3.3 -triflouroprop -1-enyl)=Dimethylcyclo propenecarboxyate], Endosulfan [6.7.8.9.10.10-hekzachloro-1.5.5a.6.9.9a - hekzahydro-6. 9-methano-2.3.4 - benzole dioxi atehiepin 3-oxide] has been investigated on human erythrocyt carbonic anhydrase isozymes (HCA-I, HCA-II) and bovine erythrocyte carbonic anhydrase (BCA) in vitro. Among the chemicals; Baythroid, Talstar, Mavrik were determined to have inhibition effect, on bovine CA and human CA isoenzymes. Dithane had effect of inhibition only on BCA. The I50 values of chemicals caused inhibition were determined by means of activity percentage [I] diagrams. The values were 2.77×10-3 M. 3.84×10-3 M, 1.56×10-2M, 2.36×10-2 M for BCA, respectively. The values of same chemicals except dithane were 1.67×10-3 M, 4.64×10-3 M, 3.9×10-3 M for HCA-I, and 3.16×10-2 M, 2.81×10-3 M, 1.04×10-2 M for 1HCA-II, respectively. On the other hand, Changes occurred in stock concentration of chemicals showed activator effect were calculated. According to the results reached, 10-2 M cupravit, 4.17×10-2 M endosulfan and 10-2 M bayleton in stock concentration activated on both BCA and HCA-II at different levels. The values activation increases of these chemicals on BCA were 29.90, 46.40, 43.70 %, and 67.11, 57.23, 31.88 % for HCA-II, respectively. Cupravit and bayleton which activated to BCA and HCA-II were ineffective on HCA-I. Values of endosulfan was determined to be 114.40 %. Penncozeb was recorded ineffective for all isozymes.

Evaluation of the Potential Hazards of Ship-Generated Waste in Maritime Industry Using a Type-2 Fuzzy Analytical Hierarchy Process
(Univ Buckingham Press, 2020) Celik, E.; Soner, O.; Akyuz, E.; Arslan, O.
Ships create a large amount of pollutions to marine and coastal environment where its pollutants have negative effects to human and maritime habitat. Depending on the nature of ship-generated waste, rules and regulations determine discharging procedures. This paper focuses on evaluating of potential hazards of ship-generated wastes on the environment whether it may be discharged into the sea or disposed of on port facilities. Thus. marine and costal environmental effects can be discussed analytically to improve human and ecological health. To achieve this purpose. analytic hierarchy process (AHP) extended with interval type-2 fuzzy sets (IT2FSs) is used. While AHP method is used for prioritizing the potential ship-generated waste, the IT2FSs deal with uncertainty and vagueness in the process of obtaining expert decision. Beside assessment of the environmental impacts, the paper contributes to enhance coastal and marine environmental awareness with respect to the ship-generated waste.
