“…As mentioned above, CB-209 was not detected or its concentration was low in the soil around the industrial area in the previous study ( Table 1 ). Nevertheless, Tremolada et al [ 36 ] found that CB-209 unexpectedly showed high concentrations (31–364 pg/g) with respect to the other congeners in soil from a high-altitude mountain pasture in the Italian Alps. On the other hand, some other studies have reported high proportions of CB-209 in water and sediment samples.…”

The concentrations of polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were determined in soil samples collected around an industrial park in Northwest China, to investigate the potential impacts of park emissions on the surrounding environment. The total concentration ranges of PCBs, PCNs, and PCDD/Fs in the soil samples were in 13.2–1240, 141–832, and 3.60–156 pg/g, respectively. The spatial distribution and congener patterns of PCBs, PCNs, and PCCD/Fs indicated that there might be multiple contamination sources in the study area, so source apportionments of PCBs, PCNs, and PCCD/Fs were performed by a positive matrix factorization model based on the concentrations of all target congeners together. The results revealed that these highly chlorinated congeners (CB-209, CN-75, and OCDF) might be derived from phthalocyanine pigments, the legacy of Halowax 1051 and 2,4-D products, which together contributed nearly half of the total concentration of target compounds (44.5%). In addition to highly chlorinated congeners, the local industrial thermal processes were mainly responsible for the contamination of PCBs, PCNs, and PCDD/Fs in the surrounding soil. The total carcinogenic risk of PCBs, PCNs, and PCDD/Fs in a few soil samples (0.22 × 10−6, 0.32 × 10−6, and 0.40 × 10−6) approached the threshold of potential carcinogenic risk (1.0 × 10−6). Since these pollutants can continuously accumulate in the soil, the contamination of PCBs, PCNs, and PCDD/Fs in surrounding soil deserves continuous attention.

“…A comparison between measured and predicted concentration in air was not possible for the most abundant congener in soil (PCB 209) because it was not present in the measured concentrations dataset (Colombo et al, 2013). However, PCB 209 was found (Tremolada et al, 2015) in soil samples of the Andossi Plateau, a mountain location about 150 km away from the Brescia site. Given the lack of PCB 209 in Fenclor and Aroclor mixtures (apart from Fenclor DK) this can be a confirmation of the possibility that the Brescia site could be the origin of PCB 209 found.…”

Cities and contaminated areas can be primary or secondary sources of polychlorinated biphenyls (PCBs), dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and other chemicals, into air and soil and can influence the regional level of some of these pollutants. In a contaminated site, the evaluation of such emissions can be crucial in the choice of the remediation technology to be adopted. In the city of Brescia (Northern Italy), more than 100 ha of agricultural areas were contaminated with PCBs, PCDD/Fs and heavy metals, originating from the activities of a former PCB factory. In order to evaluate the current emissions of PCBs and PCDD/Fs from the contaminated site, in a location where other current sources are present, we compared measured and predicted air concentrations, resulting from chemical volatilization from soils as well as fingerprints of Brescia soils and of soils contaminated by specific sources. The results confirm that the contaminated area is still a current and important secondary source of PCBs to the air, and to a lesser extent of PCDFs (especially the more volatile), but not for PCDDs. PCBs in soils have fingerprints similar to highly chlorinated mixtures, indicating contamination by these mixtures and/or a long weathering process. PCB 209 is also present at important levels. PCDD fingerprints in soil cannot be related to current emission sources, while PCDFs are compatible to industrial and municipal waste incineration, although weathering and/or natural attenuation may have played a role in modifying such soil fingerprints. Finally, we combined chemical and microbiological analyses to provide an integrated approach to evaluate soil fingerprints and their variation in a wider perspective, which accounts for the mutual effects between contamination and soil microbiota, a pivotal hint for addressing in situ bioremediation activities.

“…Os PCBs constituem um conjunto de óleos sintéticos composto por substâncias organocloradas, sendo que uma molécula pode variar consideravelmente no que se refere à quantidade de cloro em sua estrutura. Enquadram-se como substâncias sintéticas compondo os doze poluentes orgânicos persistentes (POPs) no âmbito da Convenção de Estocolmo (MARCÍLIO et al, 2014) , 2000;CHATZIKOSMA e VOUDRIAS, 2007;SOBEK et al, 2015;TREMOLADA et al, 2015), desencadeando doenças graves (SOUZA e SMITH, 2013). As ocorrências obtidas foram preliminarmente analisadas mediante a averiguação do título, resumo e palavras-chaves, visando verificar se o objetivo e a metodologia predominantes de cada pesquisa se encaixavam no propósito do presente trabalho.…”
