Toxicity of 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) on the growth of Chlorella vulgaris was investigated in batch reactors. Results revealed that 4-CP did not adversely affect the growth of algae up to 20 mg/L, however higher concentrations inhibited growth appreciably and no growth was detected at 100 mg/L. 4-CP also caused some physiological changes in the algal cells as increasing initial 4-CP concentration caused a linear decrease in chlorophyll a (chl-a) content of the cell. 2,4-DCP up to 20 mg/L did not exert toxic effect on the growth of C vulgaris, rather an induction effect was evident. Unlike a linear decrease with 4-CP, no exact correlation between 2,4-DCP concentration and chl-a content of the cell was observed, but it was certain that the presence of 2,4-DCP caused some physiological changes in the cell of C. vulgaris. No biodegradation of 4-CP and 2,4-DCP was observed over a 30-day incubation. (c) 2007 Elsevier Inc. All rights reserved.

A comparative evaluation of anaerobic dechlorination of PCB-118 and Aroclor 1254 in sediment microcosms from three PCB-impacted environments Kaya, Devrim; İmamoğlu, İpek; Sanin, Faika Dilek; Sowers, Kevin R. (Elsevier BV, 2018-01-05) Aroclor 1254 (A1254) is the most toxic commercial PCB mixture produced, primarily due to its relatively high concentrations of dioxin-like congeners. This study demonstrates a comparative evaluation of dechlorination of A1254 and PCB-118 by indigenous organohalide respiring bacteria enriched from three PCB impacted sites: Grasse River (GR), NY; Fox River (FR), WI; and Baltimore Harbor (BH), MD. PCB 118 dechlorination rates in GR, BH, and FR was 0.0308, 0.015, and 0.0006 Cl-/biphenyl/day, respectively. A1254...
A critical review of the specifications and performance of antibody and DNA-based methods for detection and quantification of allergens in foods Senyuva, Hamide Z.; Jones, Ivona Baricevic; Sykes, Mark; Baumgartner, Sabine (Informa UK Limited, 2019-01-01) Despite the availability of a large number of antibody and DNA based methods for detection and quantification of allergens in food there remain significant difficulties in selecting the optimum technique to employ. Published methods from research groups mostly contain sufficient detail concerning target antigen, calibration procedures and method performance to allow replication by others. However, routine allergen testing by the food industry relies upon commercialised test kits and frequently the suppliers...
Exposure to a microplastic mixture is altering the life traits and is causing deformities in the non-biting midge Chironomus riparius Meigen (1804) Stankovic, Jelena; Milosevic, Djuradj; Savic-Zdrakovic, Dimitrija; Yalçın, Gülce; Yildiz, Dilvin; Beklioğlu, Meryem; Jovanovic, Boris (Elsevier BV, 2020-07-01) The effect of microplastics (MP) exposure on the chironomid species Chironomus riparius Meigen, 1804 was investigated using the OECD sediment and water toxicity test. Chironomid larvae were exposed to an environmentally relevant low microplastics concentration (LC), a high microplastics concentration (HC) and a control (C). The LC was 0.007 g m(-2) on the water surface + 2 g m(-3) in the water column + 8 g m(-2) in the sediment, and the HC was 10 X higher than this for each exposure. The size of the majorit...
Effect of biogenic substrate concentration on 4-chlorophenol degradation kinetics in sequencing batch reactors with instantaneous feed ŞAHİNKAYA, Erkan; Dilek, Filiz Bengü (Elsevier BV, 2006-09-01) Two sequencing batch reactors (SBRs) instantaneously fed with 200mg/l 4-chlorophenol (4-CP) were operated at different feed peptone concentrations to investigate the effect of biogenic substrate (peptone) concentrations on reactor performance, yield coefficient (Y) and 4-CP degradation kinetics. One of the reactors was operated at 10 days of sludge retention time (SRT) and the other was operated at 20 days of SRT. High chemical oxygen demand (COD) removal efficiencies (90-95%) and complete 4-CP removals (de...
Trace level determination of beryllium in natural and flavored mineral waters after pre-concentration using activated carbon KILINÇ, ERSİN; Bakirdere, Sezgin; YAMAN, MEHMET (Informa UK Limited, 2011-01-01) The concentrations of beryllium (Be) in natural and flavored mineral water samples were determined by flame atomic absorption spectrophotometer (FAAS) after pre-concentration based on the complexation of Be(+2) with a mixture of acetylacetone (pentane-2,4-dione) plus morin (3,5,7,2',4'-pentaoxyflavone) and adsorption on activated carbon. The adsorbed complex was eluted with 1.5 ml of 2.0 M HNO(3) and evaporated to dryness. After adding 1.5 ml of 2 M HNO(3) and centrifuging, Be in acid solution was determine...
