“…This corresponds with the heavy industrial presence in North China compared to South China. The levels of PCBs in the Haihe, Huaihe and Tonghui Rivers were higher than those in the Houston Ship Channel, USA (0.49e12.5 ng/L) (Howell et al, 2008), Ebro River in Spain (43.2e108 ng/L) (Gómez-Gutiérrez et al, 2006), Mississippi River (22.2e163 ng/L) and Delaware River (0.42e1.65 ng/L) (Rowe et al, 2007) (Table S2), suggesting that PCB contamination in these rivers are at the high end of the global range.…”

“…Consequently, the observed higher concentration of Deca-CB in S7 and S8 samples probably can be explained deposition into sewage sludge from the inputs of industrial effluent during the wastewater treatment processes. Because PCB-209 was not present in the most common PCB mixtures (Breivik et al, 2002;Howell et al, 2008), knowledge on distribution and sources of this congener is very limited. Howell et al (2008) indicated that the unusually high fraction of PCB-209 was found from samples in Houston Ship Channel in Texax to unusual Aroclor mixtures used in the history or contemporary sources from local industry, while Ishikawa et al (2007) confirmed PCB-209 was generated during the thermal process.…”

“…Because of these properties, PCBs have been banned since the end of 1970s in the USA and Europe and have been listed as serious threats to health and the environment by the Stockholm Convention (May 22, 2001). For these reasons, the concentrations, transport, fate and environmental risk of PCBs in various environmental media have been extensively studied (Pikkarainen, 2007;Manodori et al, 2006;Zhao et al, 2007;Howell et al, 2008). Since sludge is widely recognized as an important matrix of persistent organic pollutants, including PCBs, this class of compounds has been well documented in other countries and regions (Souze Pereira and Kuch, 2005;Eljarrat et al, 2003;Stevens et al, 2003).…”

Concentrations of polychlorinated biphenyls (PCBs) have been measured in sewage sludge samples from 8 urban wastewater treatment plants in Beijing, China. The PCB congeners were analyzed by isotope dilution high resolution gas chromatography/high resolution mass spectrometry method. The concentration of PCBs ranged from 65.6 to 157 ng/g dry weight (dw), with a mean value of 101 ng/g dw. The dioxin-like PCB WHO-TEQs (World Health Organization-Toxic Equivalents) of the sludge were lower than 1 pg /g dw. Consequently, all the concentrations of PCBs in sludge samples were below the upper limit for land application according to the Chinese legislation law for agriculture use. The PCB homologue profiles in sludge samples were dominated by tri-CBs and tetraCBs. Similar distributions have been found in one of the Chinese PCB commercial products. The patterns of dioxin-like and indicator congeners observed in this study were quite similar in all samples. The predominant congener for dioxin-like and indicator PCBs were PCB-118 and PCB-28, respectively, while PCB-126 had the highest TEQ value.

“…The uptake of PCBs by the organisms may occur through the skin and together with the food. In water environment PCBs are cumulated in sediments as well as in water organisms (Table 6) [25][26][27][28]. The cumulation in sediments is not persistent and the compounds may be released to the waters under changing environmental conditions.…”

This article describes the toxicity of organic micropollutants on tested microorganisms. Itis a current issue because organic micropollutants are identified in all elements of environmental (surface water, ground water, soils) and in food products. The organic micropollutants include: polychlorinated dibenzodioxyns PCDD, polychlorinated dibenzofurans PCDF, polychlorinated biphenyls PCB, polycyclic aromatic hydrocarbons PAH, halogenated compounds and by-products of water treatment. Some organic compounds cause hazard for health and human life due to their estrogenic biological activity, carcinogenic, mutagenic or teratogenic activity. The influence on organisms indicators of these compounds based on literature data were presented. The level of TEQ (toxic equivalency) in response to organic chlorine derivatives (PCDDs, PCDF, PCBs) is usually determined by toxic equivalency factor (TEF). The International Agency for Research on Cancer classifies organic micropollutants as carcinogenic to humans (Group 1), possibly carcinogenic (Group 2A) or probably carcinogenic to humans (Group 2B).
