“…[15] and [16] performed the basal cyto-toxicity test using cultured human cell lines, NB-1 15 assay, to samples of water obtained from wastewater and sludge treatment plants. The tests revealed that the toxicity of the effluent was more intensive than the influent and return flows from sludge treatment facilities and the organic matter released from activated sludge bacteria during their decay process 20 contributed to the increase in toxicity in the secondary effluent.…”

As wastewater reclamation and reuse becomes more widespread, risks of exposure to treated wastewater increase. Moreover, an unlimited number of pollutants can be identified in wastewater. Therefore, comprehensive toxicity assessment of treated wastewater is imperative. The objective of this study was to perform a comprehensive toxicity assessment of wastewater treatment systems using stress response 10 bioassays. This powerful tool can comprehensively assess the toxicity of contaminants. In this study, samples from conventional activated sludge treatment, membrane bioreactors (MBRs) with different pore sizes and sludge retention times (SRTs), rapid sand filtration, coagulation, nano-filtration (NF) and reverse osmosis (RO) were investigated. The results of stress response bioassays confirmed that the secondary effluent showed higher stress response than influent indicating that biological treatment 15 generates toxic compounds. The results obtained from molecular weight fractionation of water samples demonstrated that organic matter with a higher molecular weight fraction (>0.1μm) causes toxicity in secondary effluent. Furthermore, supernatant from MBR reactors showed toxicity regardless of SRT. On the other hand, stress response was not detected in MBR permeates except for an MBR equipped with a larger pore size membrane (0.4μm) and with a short SRT (12 days). While rapid sand filtration could not 20 remove the toxic compounds found in secondary effluent, coagulation tests, operated at an appropriate pH, were effective for reducing stress response in the secondary effluent. Experimental findings also showed that stress response was not detected in cases of NF and RO permeate subsequent to MBR treatment.

“…Narita ve arkadaşları, insan hücresi kültürünü kullanarak atıksu arıtma tesisi giriş, çıkış, çöktürme tankı geri dönüş akımı, susuzlaştırma prosesi geri akımı, atık yakma tesisi geri akımı olmak üzere 5 farklı su örneğinde toksisiteyi gözlemişlerdir. Buna göre, çıkış suyunda toksisitenin daha yüksek olduğu bulunmuştur [20]. Yi ve arkadaşları tarafından yapılan çalışmada, atıksu arıtma tesisi çıkışı ve alıcı ortamdaki toksisitenin giriş atıksuyundan yüksek olduğu bulunmuştur [21].…”

ÖZETEndüstriyel atıksular, proseste kullanılan hammadde ve kimyasallar ile proses türüne göre çok çeşitli kirleticileri içermektedir. Bu nedenle, bu atıksuların çevresel etkilerini kontrol amacıyla fiziksel ve kimyasal parametrelerin yanında toksisite'nin de izlenmesi yönetmeliklerde yer almıştır. Bu çalışmada, dünyadaki mevcut durum özetlenerek Ülkemizde endüstriyel deşarjların kontrolünde uyulması gereken Su Kirliliği Kontrolü Yönetmeliği'ndeki Balık Zehirlilik Seyrelme Faktörü (ZSF) parametresinin istatistik yöntemler ile analizi yapılmaktadır. Bu çalışma sonucuna göre, belirli sektörlerde ZSF ile bazı parametreler arasında ilişki gözlenirken (tekstil sanayinde KOI-ZSF %17,2; metal sanayinde kadmiyum, çinko-ZSF %100 bağlı), bazı sektörlerde (selüloz ve kimya) anlamlı bir ilişki bulunamamıştır. Kirlenmenin tanımının değiştiği ve öncelikli kirleticilerin deşarj limitleri arasında yer almaya başladığı günümüzde toksisite parametresi ile ilgili durumun da güncellenmesinin Ülkemiz için çevre korunması konusunda acil bir öncelik olduğu açıktır.Anahtar Kelimeler: Balık Zehirlilik Seyrelme Faktörü, Endüstriyel Atıksu, İstatistik, Su Kirliliği Kontrol Yönetmeliği, Toksisite. STATISTICAL CORRELATION OF TOXICITY MONITORING METHOD WITH POLLUTION PARAMETERS FOR INDUSTRIAL WASTEWATER DISCHARGES IN TURKEY ABSTRACTIndustrial wastewaters contain various pollutants due to the different raw materials and chemicals used in the process. It has been legislatively established that toxicity is a useful and necessary parameter along with physical and chemical parameters for controlling and inspecting the environmental effects of industrial wastewater. In this study, the current situation in the World is presented and the case of toxicity dilution factor (TDF) defined in Turkish Water Pollution Control Legislation is discussed using statistical evaluation methods. As a result of this study, for some industrial sectors, there has been found some significant relationship between TDF and other parameters required in the discharge limits (in textile industry KOI-ZSF % 17.2; in metal industry Cd, Zn ZSF: %100 bound), whereas for some of them (cellulose and chemical) there was no significant correlation observed. For protecting the environment of our country, It's quite clear that toxicity monitoring emerges an update in the discharge limits, since the definition of pollution has been changed and priority pollutants have been included among discharge parameters.

Unlike to natural organic matters (NOMs), effluent organic matters (EfOMs) are not well understood due to their complexity and heterogeneity. In this study, EfOMs from sewage and industrial wastewater treatment effluents and Suwannee River NOM (SRNOM) were isolated into hydrophobic (HPO), transphilic (TPI) and hydrophilic (HPI) fractions. Specific ultraviolet absorbance (SUVA) and fluorescence excitation emission matrix (FEEM) analyses were used to characterize physicochemical properties. In addition, acute toxicity and oxidative stress to Daphnia magna were evaluated to characterize toxicological properties. EfOMs showed similar properties to microbially derived organic matters having low hydrophobicity, which are totally different from SRNOM having high hydrophobicity. Moreover, acute toxicity and antioxidant enzyme activity in D. magna was largely dependent on fraction types of EfOMs. These findings suggest that EfOMs have different physicochemical and toxicological properties compared with those of NOMs, which needs to be further identified with various sources of EfOMs.
