“…The maximum PCDF concentrations of 490 and 540 pg/g dw were found at locations 5 and 6 respectively, which were one magnitude greater than those obtained at the other locations (ranging from 30 to 86 pg/g dw). The total PCDD/Fs concentrations (range: 210 to 850 pg/g dw, with a mean value of 500 pg/g dw) in the agricultural area in Taizhou were higher than those in some areas such as Ya-Er Lake area, Beijing, Hangzhou and Taiwan in China (Wu et al, 2002;Zhou et al, 2006;Yan et al, 2007;Cai et al, 2008), but were lower than those from some highly contaminated regions such as Akita in Japan, Bien Hoa Airbase in Southern Vietnam and Brescia in Italy (Kiguchi et al, 2007;Mai et al, 2007;Turrio-Baldassarri et al, 2007). When compared with Guiyu, another ewaste recycling center in China, the PCDD/Fs concentration levels were in accordance with those found in a rice field, greater than those observed in a printer roller dump site, and less than those obtained in an acid leaching site (Leung et al, 2007).…”

Our aim was to identify polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzo-p-furans (PCDFs) in agricultural farmland soils in the Northwest of Mexico. We obtained ≈50 g of soil in five Yaqui Valley (VY) agricultural fields in the north-western Mexican State of Sonora and in five Culiacán Valley (VC) agricultural fields in the north-western Mexican State of Sinaloa. Fields with minimal tillage, with ferti-irrigation, and those with intensive aerial and manual tillage were included. All soil samples were subjected to the chemical activated luciferase gene expression (CALUX(®)) test to determine PCDD/F. On average, samples contained 4.2 ± 1.2 PCDD/F ppt TEQ; VY soil samples contained 4.72 ± 1.23 PCDD/F ppt TEQ, while VC soil samples showed 3.6 ± 1.1 PCDD/F ppt TEQ (p = 0.47). On considering tillage-type, in agricultural fields catalogued as intensive tillage, PCDD/F concentrations were 4.40 ± 0.43 in agricultural fields catalogued as intensive tillage, while in farmlands of another tillage-type these concentrations were slightly higher (5.53 ± 0.8).

“…The fields were suspected of being polluted by pesticides and contaminated irrigation water. The mean PCDD/F concentrations in the samples were about 26.21 pg g À1 (0.11 pg I-TEQ g À1 ) for samples from the cotton field and 95.55 pg g À1 (1.30 pg WHO-TEQ g À1 ) for samples from the rice field (Wu et al, 1998;Wu et al, 2002). The congener profiles of the samples showed high proportions of OCDD, OCDF, and 1234678-HpCDD.…”

Aimed to give a preliminary image of dioxin pollution in China, chemometric analysis was performed to determine background dioxin levels during the period 1994-2002 and potential emission sources. Using principal components analysis (PCA), the congener profiles of 71 sediment samples from rivers, lakes, and sea bays around China were compared with the congener profiles of various known or suspected industrial, residential, and municipal dioxin sources to determine whether the dioxin residues typically found in a broad range of potential environmental sources could explain the presence of these chemicals in China. It was found that the background dioxin levels of China were similar to those of lightly polluted samples from other countries during the period 1994-2002. Primary ferrous ore sintering and secondary lead and aluminum smelters were the major sources of dioxin emission in China. Chloranil and wastewater from chemical plants, sodium pentachlorophenate, and pulp bleaching were also important sources of dioxin emission. Open burning of e-waste as well as diesel-fueled and leaded gas-fueled vehicles were additional possible sources of dioxin. In contrast to other countries, in China, flue gases from incineration of municipal waste, hazardous waste, and medical waste might be minor sources of dioxin emission.
