“…The levels were comparable to those found at a site for dismantling PCBcontaining equipment in Taizhou (Zhao et al, 2006b), and at the open-burning site in Guiyu (Wong et al, 2007b). However, they were lower than those detected at some heavily polluted sites (Priha et al, 2005;Herrick et al, 2007;Turrio-Baldassarri et al, 2007). The greatest total concentrations of PCBs were observed at locations 5, 6 and 9 (65-100 ng/g dw), all of which were relatively near to the e-waste recycling sites when compared to other locations.…”

“…In samples N o 5, 10 and 11 a higher proportion of penta-PCBs is observed than in other samples. Aroclor 1254 and 1260 were reported as the most used ones, especially in paints and sealants in some European countries [30,31]. Polychlorinated biphenyls like Delor (Delotherm, Hydelor) were produced by company Chemko Stražské (East Slovakia in former Czechoslovakia) from 1959 till 1984.…”

In a field experiment, the transfer of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from contaminated soil to maize (Zea mays L.), sunflower (Helianthus annuus), poplar (Populus nigra × P. maximowiczii) and willow (Salix × smithiana) and the distribution of PCB congeners in maize and sunflower was investigated. The former waste incinerator in Hradec Králové (Czech Republic) was chosen for the experiment. Results of plot screening showed heterogenous contamination by PCBs and PAHs. PCB soil contamination was evidently caused by Delor 106 or Aroclor 1260 stocking and PAH contamination by chemicals containing fluoranthene, benzo/b/fluoranthene, phenanthrene and pyrene. Tested plants were planted on a contaminated field site, in soil contaminated with 1530 µg/kg of total PCBs and 0.138 and 3.42 mg/kg of total PAHs. The results show that maize and sunflower roots accumulated the most PCBs from soil. These plants accumulated hexa- and heptachlorobiphenyl congeners more than tri-, tetra-, and pentachlorobiphenyl congeners. Total concentrations of PAHs in tested plants ranged from 0.096 to 1.34 mg/kg. The highest phenanthrene concentration was found in aboveground biomass of sunflower and the highest concentration of pyrene, in maize roots.

“…PCB were used for industrial application in closed systems: lubricants (industrial oils), dielectric fluids in electrical equipment such as transformers, capacitors, heat transfer, and hydraulic systems (Borja et al 2005;Erickson and Kaley 2011;Kas et al 1997;UNEP 2002). They were also employed in open uses, such as pesticide extenders, sealants, carbonless copy paper, lubricants, paints, adhesives, plastics, flame retardants, and dedusting agents on roads (ATSDR 2000;Diamond et al 2010;Kohler et al 2005;Priha et al 2005). Other uses, in partially open systems, include: heat transfer fluids; hydraulic fluid in lifting equipment, trucks and high-pressure pumps; vacuum pumps; voltage regulators; liquid filled electrical cables; and liquid filled circuit breakers (ATSDR 2000;Eisler and Belisle 1996;Erickson and Kaley 2011;Furukawa and Fujihara 2008).…”
