Despite the continuously increasing environmental awareness and legal regulations against environmental pollution, domestic and industrial wastewaters are discharged into the nearest receiving water bodies without any treatment. Haphazard disposal of wastes into the environment and untreated wastewater discharged into rivers and streams pollute air, water, and soil and create a danger for human, animal, and plant health. All these wastes should be treated before their disposal and discharge to leave a healthier and cleaner environment for future generations. The constructed wetlands, defined also as natural treatment systems, are the systems emulating the natural wetland systems. They are commonly used for treatment of domestic and industrial wastewater in specially designed basins with aquatic plants and can easily be used for small-to-medium sized communities. There are 51 constructed wetlands in the Kayseri Province of Turkey and more than three-fourths have some kind of structural failure and are not operating properly. In this study, all of these constructed wetlands were investigated with regard to improper design aspects and possible failures. The common failures were identified as improper design, construction and site selection, substrate clogging and consequent (poundings), insufficient plantation, leakage through slopes, and lack of post-construction operation, monitoring, and maintenance activities. The reasons for such failures and possible corrective measures are also proposed in this study.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":"23 1","pages":"38-44"},"PeriodicalIF":0.0,"publicationDate":"2014-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70622033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there was a progressive increase in the enforced dormancy with an increase in salinity treatments. Thiourea substantially improved seed germination and the rate of germination of all test species under saline conditions. Kinetin partially alleviated the salinity effect on the seed germination of H. glomeratus and P. harmala but not for L. latifolium. GA3 substantially improved the seed germination in L. latifolium. Nitrate and proline had no effect under saline conditions. Seed germination was completely inhibited in L. latifolium, partially in P. harmala, but had no effect on H. glomeratus seeds when germinated in the dark.

In this study, pyrolysis was utilized for the stabilization of Pb into a solid product. In the first stage of the study, three types of phytoremediation plants were used, rape (Brassica napus), sunflower (Helianthus annuus), and corn (Zea mays). Their seeds were sown in simulated soils prepared with the addition of Pb compounds in a laboratory. The effect of chelate on the remediation capacity of the plants was investigated by the addition of EDTA in different concentrations. In this way, the transportation of Pb from the contaminated soils to the plants was examined. In the second stage, the initial plant compositions were determined by elemental analysis (C, H, N, and S), as well as a moisture, ash, volatile matter, and fixed carbon analysis. The contaminated hyperaccumulator plants were pyrolyzed at 500°C, with a heating rate of 35° C/min, in a fixed bed stainless steel (380 S) 240 cm 3 reactor. After pyrolysis, the Pb contents of the solid and liquid products were determined. A Toxicity Characteristics Leaching Procedure (TCLP) analysis was also utilized for the solid product. In this study, high phytoremediation efficiencies were observed for the phytoremediation of Pb contaminated soil using sunflower, corn, and rape, especially in the case of the chelate addition. Of the three plants, the best Pb removal efficiency (92%) from the soil was obtained with the rape. According to the pyrolysis results, the highest yields of liquid and solid products were obtained from the sunflower with gas products being obtained from the corn pyrolysis.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":"23 1","pages":"51-56"},"PeriodicalIF":0.0,"publicationDate":"2014-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70622238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spermidine (Spd) was the most abundant PA in the two white rot fungi, while Spermine (Spm), and Putrescine (Put) were found only in trace amounts or were not determined. The highest Spd levels (1952.05 μg/DW and 2391.54 μg/DW) were observed in 1 ppm Cd at 15 days of incubation in T. versicolor and F. trogii respectively. The laccase activity of both species, especially in the 15-day cultures, showed a significant increase compared to the control. The highest increase was evident at 100 ppm Cd where the laccase activity was over 19 fold higher than that of the control sample in the 15 day culture of T. versicolor. The dry biomass in the 0.1 and 1 ppm Cd concentrations showed a significant increase in T. versicolor in the six and 15 day incubation periods. In all cases, the dry biomass in both the six and 15 day cultures of F. trogii showed a significant increase compared to the control cultures.

The titanium content, chromium oxide content, formaldehyde content, shrinkage temperature, pH value, ash content, and fat content of the tanned leathers were investigated for the determination of chemical characterization. The tensile strength, elongation at break, tear strength, and colour measurement tests were also carried out for investigating the physical properties. The titanium tanned leathers had a mean shrinkage temperature of 79.5oC and more yellowish colour than the chromium tanned leathers. Their tensile strength properties were found similar with chromium leathers, while the elongation at break was found to be lower and tearing resistance was higher. The usage amount of 2.5% could be perfectly advised for the tanning process based on the titanium tanning material for achieving optimal properties required from different leather types such as upholstery, automotive and shoe upper leathers.
