This paper presents the characterization of the microbial community responsible for the in-situ bioremediation of hexachlorocyclohexane (HCH). Microbial community structure and function was analyzed using 16S rRNA amplicon and shotgun metagenomic sequencing methods for three sets of soil samples. The three samples were collected from a HCH-dumpsite (450 mg HCH/g soil) and comprised of a HCH/soi...
1. Albino rats were fed on diets containing 30, 120 or 200 g protein/kg with or without the incorporation of dichlorodiphenyltrichloroethane (DDT) or hexachlorocyclohexane (HCH) at 100 mg/kg diet for 4 weeks. 2. The activities of the liver microsomal enzymes NADPH-cytochrome reductase (EC 1.6.2.4), flavoprotein-linked monooxygenase (EC 1.14.14.1) and O-demethylase were significantly greater in ...
Organochlorine pesticides, such as HCH (Hexachlorocyclohexane) and DDT (dichloro diphenyl trichloro ethane) and its metabolites were analysed in commercially important fishes, collected from the Dadar fish market (Mumbai) in July 2011. Total DDT concentration varied between 14.88 and 58.30 ng.g-1 in the Lisa parsia and Chirocentrus dorab respectively. The minimum and maximum concentrations of t...
Nine halogenated monoterpenes isolated from the red alga Plocamium cartilagineum have been evaluated for their cytotoxic effects on the tumor cell lines CT26 (murine colon adenocarcinoma), SW480 (human colon adenocarcinoma), HeLa (human cervical adenocarcinoma) and SkMel28 (human malignant melanoma) with several multidrug resistance mechanisms and the mammalian non-tumor cell line CHO (Chinese ...
Pesticide residue is a major problem in food safety. It particularly important to detect pesticides fruits and vegetables quickly effectively The near infrared spectroscopy (NIR) technique was explored as predict organochlorine Mesona chinensis Benth. Fourty-three samples were sacaned powder Antaris II FT-NIR. Samples split into two sets, one set used calibration (n=35) where the remaining (n=S...
As a result of its unique location, Turkey receives air masses from Europe, Russia, Middle East, and Africa, making it an important place in terms long-range atmospheric transport (LRT) contaminants. Atmospheric levels 22 organochlorine pesticides (OCPs), 45 polychlorinated biphenyls (PCBs), 14 polybrominated diphenyl ethers (PBDEs) were measured two metropolitan cities, Istanbul Izmir, on week...
How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data regarding DDT/HCH deposition were obtained from the published ...
