Dioxin-like polychlorinated biphenyl adsorbent obtained from enzymatic saccharification residue of lignocellulose

Bioresource Technology, 2011
In this study, the effective utilization of lignocellulose residue as an adsorbent was investigated. Japanese cypress wood flour subjected to hydrothermal pretreatment and ball-mill grinding was saccharified with an enzyme. The residual wood flour was carbonized and activated by physical and chemical activation to produce adsorbents for persistent ...

Content of polychlorinated dibenzo-p-dioxins, dibenzofurans and dioxin-like polychlorinated biphenyls in fish from Latvian lakes

Chemosphere, 2013
Seventeen polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/PCDFs) of the highest priority as well as twelve dioxin-like polychlorinated biphenyls (dl-PCBs) were analyzed in the muscle tissues of the following freshwater fish species sampled from eleven Latvian freshwater lakes: perch (Perca flavescens), carp (Cyprinus carpio ...

Dietary intake of polychlorinated dioxins, furans and dioxin-like polychlorinated biphenyls from foods of animal origin in China

Food Additives and Contaminants, 2007
Four food groups of animal origin from the Chinese Total Diet Study (TDS) in 2000 were analysed for 17 polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and 12 dioxin-like polychlorinated biphenyls (PCBs). The samples were from four regions, covering 12 provinces of China.

Polychlorinated dibenzo-p-dioxins, dibenzofurans, and dioxin-like polychlorinated biphenyls in rice plants: Possible contaminated pathways

Chemosphere, 2006
Uptake of dioxins was confirmed in rice plants. We determined (i) dioxin concentrations and isomer profiles in leaf+stem samples of rice plants grown in three soils with different dioxin concentrations and isomer profiles and (ii) temporal changes in dioxin concentrations and isomer profiles in rice grown in a paddy field on which agricultural ...

Polychlorinated dibenzo-p-dioxins, dibenzofurans, and dioxin-like polychlorinated biphenyls in rice straw smoke and their origins in Japan

Chemosphere, 2011
Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (DL-PCBs) contained in the smoke generated from rice straw burning in post-harvest paddy fields in Japan were analyzed to determine their congener profiles.

Distribution of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs/Fs) and dioxin-like polychlorinated biphenyls (dioxin-like PCBs) in the soil in a typical area of eastern China

Journal of Hazardous Materials, 2009
The distribution and concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (dioxin-like PCBs, also called co-PCBs) in a typical area of eastern China were evaluated by analysis of 21 soil and 6 sediment samples.

Nutrition Recommendations for Estonian Fishermen (Dioxins and Dioxin-Like Polychlorinated Biphenyls)

Latvian Journal of Chemistry, 2012
Nutrition survey of coastal fishermen was conducted in May 2010, when the fishing season was at its peak. More than half of the participants in the survey eat fish and fish products in April and May more than during the second half of the year At that time fishermen and their families eat fish the most. Thus, the amount of toxins found in the course of

Assessment of dioxins and dioxin-like polychlorinated biphenyls in the palm oil supply chains

Quality Assurance and Safety of Crops & Foods, 2014
Samples of palm oil and palm kernel oil (PKO) products were collected from two palm oil processing premises which were named as premise A and B. These samples were then analysed for dioxins and dioxin-like polychlorinated biphenyls (PCBs) content. The concentration of dioxins in the palm oil and PKO samples from premise A ranged from 0.128 World Health

Dioxin-like and non-dioxin-like toxic effects of polychlorinated biphenyls (PCBs): implications for risk assessment.

Central European journal of public health, 2000
Polychlorinated biphenyls (PCBs) are persistent, bioaccumulative and toxic contaminants in the environment. Individual PCB congeners exhibit different physico-chemical properties and biological activities which result in different environmental distributions and toxicity profiles.

[Levels and distribution of the dioxin-like polychlorinated biphenyls (PCBs) in the surface sediment of the Yellow River ].

Huan jing ke xue= Huanjing kexue, 2014
The levels of DL-PCBs in the surface sediments collected in 15 different sampling sites from the Tibetan Plateau to the Yellow River estuary along the Yellow River were measured using the GC-MS. The concentrations of ∑DL-PCBs ranged from 2. 3 to 14.8 pg.g-1 and the TEQs of DL-PCBs were between 0. 001 4 and 0. 023 1 pgg-1 , with an average of 0.
