Study on the biodegradation of perfluorooctanesulfonate (PFOS) and PFOS alternatives
OBJECTIVES In this study, we investigated the biodegradation features of 4 perfluorooctanesulfonate (PFOS) alternatives developed at Changwon National University compared to those of PFOS. METHODS Biodegradation testing was performed with microorganisms cultured in the good laboratory practice laboratory of the Korea Environment Corporation for 28 days following the Organization for Economic ...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولBioconcentration and Metabolism of Emodin in Zebrafish Eleutheroembryos
Emodin is a major active anthraquinone of various herbal laxatives, which can exert many pharmacological effects. However, chronic use of anthranoid laxatives, even at low dosages, may cause melanosis coli (MC). It has been suggested that the accumulation of anthraquinones is a risk factor in the MC process. To investigate the accumulation of emodin, we conducted a bioconcentration study of emo...
متن کاملComparison of waterborne and in ovo nanoinjection exposures to assess effects of PFOS on zebrafish embryos.
Since perfluorooctane sulfonate (PFOS) had been detected in eggs of seabirds and fish, toxicity of waterborne PFOS to embryonic development of zebrafish (Danio rerio) was investigated. However, because assessment of effects by use of dietary exposure of adults is time-consuming and expensive, a study was conducted to compare effects on embryos via nanoinjection and waterborne exposure. Nanoinje...
متن کاملChronic Effects of Waterborne PFOS Exposure on Growth, Development, Reproduction and Hepatotoxicity in Zebrafish
To evaluate the potential effects on growth and reproduction of perfluorinated compounds (PFCs), the zebrafish fry (F0, 14 d post-fertilization, dpf) were chronically exposed to various concentrations of PFOS (0, 10, 50 and 250 μg l–1) until sex mature (70 d) and effects on reproductive capacity and endocrine disrupted potential were assessed. No significant adverse effects on survival were obs...
