Imidacloprid (IMI) is a widely used systemic insecticide to control plant pests following soil, seed or foliar applications, and is subject to cleaning. Bioremoval is one of the economical water treatment techniques in remediation. Trials were carried out at pH 7.5 for IMI at media with and without triacontanol (TRIA), a naturally occuring plant hormone and Salicylic acid (SA). The removal capacities of Synechocystis sp. and Phormidium sp. were found higher in media containing TRIA and Salicylic acid. The removal efficiencies were measured at 150 mg L-1 concentrations of IMI. Synechocystis sp. and Phormidium sp. had the maximum values of removal of IMI in the media containing the hormone and Salicylic acid. The results showed that TRIA and Salicylic acid could be considered as a stimulant in pesticide removal by the isolated cyanobacteria cultures.

The study focused on the effects of realistic levels of engine exhaust emissions of liquid petroleum gas (LPG) and gasoline (GSN) on Phormidium sp. and Chlorella sp. Multi parameters including pH, different medial compositions, fuel types, flow rates and biomass concentrations were described in detail. Effects of some growth factors such as triacontanol (TRIA) and salicylic acid (SA) have also been tested. The maximum biomass concentration of Phormidium sp. reached after 15 days at 0.36 and 0.15 g/L initial biomass concentrations were found as 1.160 g/L for LPG emission treated cultures and 1.331 g/L for GSN emission treated cultures, respectively. The corresponding figures were 1.478 g/L for LPG emission treated cultures and 1.636 g/L for GSN emission treated cultures at 0.65 and 0.36 g/L initial Chlorella sp. biomass concentrations. This study highlights the significance of using Phormidium sp. and Chlorella sp. for utilization of LPG and GSN engine exhaust emissions by the help of growth factors.

Trials were performed in media including triacontanol hormone, Reactive Orange 14, Reactive Red 120, Reactive Black 5, Remazol Brilliant Blue R (RBBR), and also hormone against the controls. Algae could remove RBBR with the highest dye removal percentage (56%) among the tested dyes. The optimum pH was 9 in removing 50 mg L−1 RBBR at a dye removal percentage of 47.1%. The role of laccase activity of Gonium sp. was also investigated. This first attempt in the literature showed the involvement of the enzyme in the algal growth and bioremoval process. In the presence of the plant growth hormone in the culture, the activity showed a steady and significant increase up to nearly sixfold between 5th and 14th days of incubation.

The microorganisms were cultivated in 100 ml BG 11 medium and incubated at 30 • C under continuous illumination (12.5 w m −2 (2400 lx)) for 20 days in plant growth chamber. Trials were carried out at pH 9.5 for Reactive Red, pH 8.5 for Remazol Blue and Reactive Black B removal in media without and with triacontanol (TRIA). Removal capacities of Synechocystis sp. and Phormidium sp. were found higher in media containing TRIA. So that, Synechocystis sp. and Phormidium sp. removed Reactive Red with 25.7% and 35.4%, Remazol Blue with 37.5% and 25.5%, and Reactive Black B with 29.2% and 28.3% yield at 25 mg l −1 dye concentrations, respectively. There is no report investigating dye removal by Synechocystis sp. and removal of pollutants in media including TRIA hormone. Our data indicated the cyanobacteria tested in this study were suitable for effective treatment processes of such wastewaters including reactive dyes, and their removal capacity could be increased by TRIA, through stimulation of the biomass production.

In the vast literature describing removal of reactive dyes, considering the lack of reports using of common duckweed in wastewater treatment apparently due to the inadequate efficiency. In the present study, the experiments showed that 1 mg l −1 triacontanol stimulated duckweed growth. The effect of different dye types (Reactive Orange 14, Reactive Red 120, Reactive Black 5, Brilliant Blue R, and Reactive Brilliant Blue R) onto duckweed growth was tested. Plants grew at most in media with Brilliant Blue R. The highest biomass, in terms of frond number (87 ± 1.5) were accompanied with 59.6% maximum dye removal were found in samples containing 2.5 mg l −1 initial Brilliant Blue R and 1 mg l −1 triacontanol, indicating hormonal stimulation of both activities. The results presented here that L. minor (L.) could be used effectively to treat wastewaters containing dye.

Although Chlorella sp. has been studied to remove pollutants from water, its capacity to remove B has not been investigated yet. Boron removal levels of newly isolated Chlorella sp. were investigated in BG 11 media with stimulators as triacontanol (TRIA) and/or sodium bicarbonate (NaHCO 3 ) and without them, to test if they could increase the removal efficiency by increasing biomass. The assays were performed to determine the effect of different medial compositions, B concentrations, pH and biomass concentrations onto removal efficiency. Boron removal was investigated at 5e10 mg/L range at pH 8 in different medial compositions and maximum removal yield was found as 32.95% at 5.45 mg/L B in media with TRIA and NaHCO 3 . The effect of different pH values on the maximum removal yield was investigated at pH 5e9, and the optimum pH was found again 8. The interactive effect of biomass concentration and B removal yield was also investigated at 0.386e1.061 g wet weight/L biomass. The highest removal yield was found as 38.03% at the highest biomass range. This study highlights the importance of using new isolate Chlorella sp. as a new biomaterial for B removal process of waters containing B. ª journal home page: www.elsevier.com/loca te/watres w a t e r r e s e a r c h 4 6 ( 2 0 1 2 ) 1 6 7 e1 7 5 0043-1354/$ e see front matter ª

Yaygınlaşan susuzluk, açlık, fakirleşme, ekolojik göç, aşırı üretim ve tüketim yanında fakirlik kaynaklı doğa tahribi kısırdöngüsü Akdeniz Havzası ve Türkiye'yi de etkilemektedir. Bu çerçevede çözümü giderek zorlaşan sorun ekolojik koşulların zorlayıcı etkileri artarken sürdürebilir kalkınmayı gerçekleştirebilmektir. Bunun için de çevresel kısırdöngüyü kırma konusundaki bilimsel çabaların özünü oluşturan bütünsel yaklaşımların temel prensiplerini, uygulamadaki başarıları ve yeterliliklerini, geleceğe dönük projeksiyonları irdeleyerek uzun erimli planlar yapmaktır.

Bu amaçla Türkiye genelinde 62 işletmenin katıldığı bir anket çalışması yapılmıştır. Anket sorularının hazırlanmasında uluslararası literatürde yer alan genel sorun ve zorluklar yanında, Türkiye'de önceki yıllarda hazırlanan tez çalışmalarından yararlanılmıştır. Elde edilen sonuçlar 'Excel' ve SPSS paket programları ile analiz edilmiştir. Anket sonuçlarının literatürde belirlenenler ile paralellik gösterdiği, ancak hissedilme sıklık ve derecelerinde farklılıklar olduğu gözlemlenmiştir. Anket çalışması neticesinde görülen problem ve zorluklardan en baskın olanları; "çevre ile ilgili konulardaki alt yapı yetersizliği", "atık gideriminde lisanslı, uygun alanların bulunamaması", "devletin ve ilgili kurumların destek ve teşviklerinin yeterli olmaması" şeklinde belirlenmiştir. Bu sonuçlar literatürde verilenlerle karşılaştırılarak tartışılmıştır. Sonuç olarak başta bu sorunlar olmak üzere, belirlenen tüm problemlerin çözümü için, toplumun her düzeyinde işlevsel çevre bilincinin oluşturulması ve arttırılmasının, çevre yönetimi alt yapısının oluşturulması ve çevreci yaklaşımların yönetsel düzeyde desteklenmesinin çok önemli ve gerekli olduğu görülmüştür.
