“…The non-toxic material (values between 0.46 TU and 4.77 TU) was collected from site III of Przemyslowe Quay (the longest distance from the Gulf of Gdansk), the middle part of Wislane Quay (site II) and from all sampling sites of Chemikow Quay (2013). Sediments determined as low toxic were collected from Wislane Quay III (mean value of 21.52 TU), Szczecinskie Quay I (mean value of 21.59 TU) which are situated closer to the center of the Bergqvist et al 1989, Koistinen et al 1995, Naf et al 1997, Verta et al 1999, Verta et al 2003, Bergqvist et al 2005 It has been noted that the most toxic sample from Chemikow Quay (2012), station III, has a disproportionate value of toxicity compared to its bottom sediment characteristics. For this reason, two coefficients of determination (R 2 ) were calculated for all parameters presented in Table 7.…”

Combustion processes are considered to be the main source of the dioxin emission in the Baltic region. Pentachlorophenol (PCP) and its derivatives, pentachlorophenyl laurate (PCPL) and sodium pentachlorophenate (NaPCP) are known as precursors of dioxins. The research was conducted to obtain the first data on the concentration of PCDD/Fs and PCP in the bottom sediments of the Port of Gdansk. Toxicity (the Microtox® test) as well as several sediment parameters have been examined.In the surface layer of bottom sediments from the Port of Gdansk, all congeners of PCDD/Fs have been detected using GC-MS/MS. The positive correlation between toxicity and physicochemical properties of the analyzed bottom sediments confirms that these parameters are important in terms of environment contamination.

“…PCDEs may be converted to more toxic polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs) by photolysis or pyrolysis (Norström et al 1977;Lindahl et al 1980;Nito et al 1997). Of particular note are those produced from municipal solid waste incinerators (MSWIs) (Koistinen et al 1995b;Passivirta et al 1986;Kurz and Ballschmiter 1995;Olie et al 1977), which are known to be major sources of PCDEs and PCDD/Fs. PCDEs and PCDD/Fs become concentrated in fly ash by post-combustion processes, forming in the presence of oxygen, their precursors, and chlorine sources (Liu et al , 2011Addink and Olie 1995;Tuppurainen et al 1998).…”

Polychlorinated diphenyl ether (PCDE) has attracted great attention recently as an important type of environmental pollutant. The influence of iron and copper oxides on formation of PCDEs was investigated using laboratory-scale flow reactors under air and under nitrogen at 350°C, a temperature corresponding to the post-combustion zone of a municipal solid waste incinerator. The results show that the 2,2′,3,4,4′,5,5′,6-otachlorodiphenyl ether (OCDE) formed from the condensation of pentachlorophenol (PCP) and 1,2,4,5-tetrachlorobenzene (Cl 4

“…PCB concentrations in the sediment ranged from 0.4 to 9.1 mg/kg, and the congener profiles are most similar to a mixture of Aroclors 1248, 1254, and 1260. The Kymijoki River in Finland was heavily contaminated with PCDD/Fs, among them 1, 2,3,4,6,7,8-and 1,2,3,4,6,8,9-heptaCDFs and octa-CDF as the dominant congeners (Koistinen et al 1995;Verta et al 1999). …”

SPONSOR/MONITOR'S ACRONYM(S) SPONSOR/MONITOR'S REPORT NUMBER(S)12 SERDPThe project investigated techniques and amendments to enhance microbial dehalogenation in sediments contaminated with organohalide mixtures and developed methods and tools to monitor the effectiveness of biostimulation processes. Micro-and mesocosm studies with organohalide-contaminated sediments demonstrated that these contain diverse communities of dehalogenating microorganisms. Dechlorination of historical PCB and PCDD/F contaminant mixtures can be stimulated by addition of amendments and/or bioaugmentation with dechlorinating bacteria. The enhanced dechlorination correlates with increased numbers of dehalorespirer populations and reductive dehalogenase genes. Identification of the specific microbial members associated with PCB-and PCDD/F-dechlorinating activity should allow for better strategies to enhance dehalogenation. The results provide compelling evidence to support further testing and development of biostimulation and bioaugmentation with dehalorespiring bacteria as environmentally less invasive and lower cost alternatives for in situ treatment of PCB impacted sediments.
