“…Considering the pollution of reservoir water, the results obtained by Chen et al [53] on the basis of water samples from the Three Gorge Dam demonstrated a significantly lower WHO-TEQ concentration (range: 0.0008-0.32439 pg/l) than the values noted in the case of the urban (Sokołówka) and rural (Sulejowski) reservoirs [23] described above, as well as other literature data [30]. Nevertheless, it should be emphasized that in contrast to the small, urban Sokołówka reservoirs, the Three Gorge Dam is one of the biggest dam reservoir in the world and plays an important role as a water supply for the Chinese.…”

Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) are unwanted by-products in a variety of industrial and thermal processes. They have been present on Earth long before the human era, since they may be also formed as a result of forest fires or volcanic explosions. Polychlorinated biphenyls (PCBs) in turn, have been intentionally produced by humans. Poland was a minor producer of PCB mixtures (Chlorofen and Tarnol), which were a source of direct and indirect environmental diffusion with PCB and less with PCDDs/PCDFs. Industrial accidents with PCDDs/PCDFs were absent in Poland. Their stability and resistance to thermal breakdown made them very dangerous for environment and, in consequence, due to their environmental persistence, bioaccumulation and biomagnification in the terrestrial and aquatic food chains, to humans. Humans may become affected by PCDDs/PCDFs and PCBs through environmental (soil and water contamination, fish and food), occupational (incinerators; pulp, paper and metallurgy industry; copper production), or accidental (Seveso accident) exposure. The aim of this review was to evaluate environmental hazard caused by PCDDs, PCDFs and dioxin-like-PCBs in the central region of Poland based on the accessible data on diffusion of those compounds in sediments and riverine, reservoir and storm water from our previous studies and discussed in the context of other achievements in Poland and elsewhere.

“…The concentrations of PCDD/Fs in Xijiang (a tributary of the Pearl River; Fig. S1) were 20.4e76.2 pg/L with I-TEQ in the range of 0.012e0.075 pg/L (Liu et al, 2008), which were greater than those in the Elbe River, Germany (0.12e0.28 pg/L) (Götz et al, 1994) and the Hudson River, USA (2.35 pg/L) (Lohmann et al, 2000) but lower than those detected in Matsuyama's (Japan) river (nde1500 pg/L) (Seike et al, 1998).…”

“…These results indicate that paddy soil runoff significantly affects dioxins (TEQ) concentration in the river. Moreover, it is revealed that RR transports significant amounts of dioxins associated with paddy soils as well as IR ( Figure 2C, D), although IR was thought to be a primary dioxins runoff from paddy fields (8)(9)(10). Interestingly, the S par values in the RR collected at St. 2, 4, and 5 decreased every time and, then, finally remained constant ( Figure 2D).…”

Significant dioxins accumulations in Japanese forests and paddy fields have been observed, and surface soil runoff caused by rainfall and irrigation (i.e., soil puddling in paddy fields) results in dioxins input into the aquatic environment. An extensive investigation into the origins and transport of aquatic dioxins in the Yasu watershed, Japan was conducted considering surface soil contamination level, land use, and type of soil runoff event (i.e., irrigation runoff [IR], rainfall runoff [RR], and base flow [BF]). Combined use of the chemically activated luciferase expression (CALUX) assay together with high-resolution gas chromatography and high-resolution mass spectrometry (HRGC/HRMS) efficiently enabled this study, so that origins, transport, and dynamic movement of aquatic dioxins in the watershed were revealed. The particulate organic carbon normalized particulate-dioxins WHO-toxic equivalent (TEQ) concentration predicted by the CALUX assay (Spar) was found to be a convenient molecular marker to indicate origins of aquatic dioxins and clearly reflect surface soil contamination level, land use, and soil runoff events. Using experimental results and theoretical modeling, the annual loading amount of dioxins at the middle reach of the river was estimated to be 0.458 mg WHO-TEQ in 2004. More than 96.6% of the annual loading amount was attributed to RR and derived almost evenly from forest and paddy fields at the study location. Because the annual loading amount at the middle reach is less than 0.5% of the total dioxins accumulated in the upper basin, dioxins runoff from the Japanese watershed will continue. This study shows that the combined use of the bioassay with HRGC/HRMS can provide new insights into dioxins transport and fate in the environment.
