“…Higher TEs contents are accompanied by higher contents of various POPs of industrial as well as agricultural origin (HCB, HCHs, DDT, and metabolites). Similar ecosystem contamination caused by anthropogenic sources was reported by Kohušová et al (2011) in the adjacent watershed of the Bílina River.…”

Skála J., Vácha R., Hofman J., Horváthová V., Sáňka M., Čechmánková J. (2017) Extensive soil sampling and screening assessment of ecosystem risks combined with a multidimensional statistical analysis were used to estimate and spatially characterize the ecosystem risks stemming from the contamination of floodplain soils in the Czech Republic. We proved structural differences in regional pollution patterns where different regional/local pollution sources led to various nature and extent of the environmental load of floodplain soils. The established spatial patterns helped reveal the areas where soils do not meet soil quality standards and where the ecosystem risks were elevated. Furthermore, the results allowed to establish priority contaminants of flood affected areas in various catchments in the Czech Republic. Combining both the magnitudes of estimated ecosystem risks and structural characteristics of pollution profiles, the highest estimated risks showed the localities with high contents of organochlorine pesticides, several samples connected to geochemical anomalies of metallogenic zones (deposits), and localities with a long history of industrial load. Since extreme weather events have recently become more frequent, our results highlight the importance of a continual monitoring of pollutant turnover in floodplain soils with a high flood frequency.

“…The source of pollution is waste water from industry, municipal sewage, agricultural procedures, and mining activities (Kohusova et al 2011). The results of a long-term study by Kohusova et al (2011) indicated that the middle and the lower stretches of the Bílina River were heavily polluted by metals and organic pollutants. The main sources of pollution were oil, coal, the chemical industry, and municipal sewage.…”

Assessment of polycyclic aromatic hydrocarbon contamination of the Bílina River (Czech Republic) using passive water samplers and fish biliary metabolites

et al. 2011

The aim of the study was to assess polycyclic aromatic hydrocarbon (PAH) contamination on the Bílina River (the Czech Republic) by measurement of three PAH biliary metabolites in fish and 16 PAHs in passive samplers. A total of sixty-one fish were collected; the indicator species were chub (Leuciscus cephalus L.; n = 25), roach (Rutilus rutilus L.; n = 17) and brown trout (Salmo trutta m. fario L.; n = 19). Three biliary PAH metabolites were measured: 1-hydroxypyrene (1-OHP), 2-naphtol, and 1-hydroxyphenanthrene, but only 1-OHP was detected in all fish. The highest median value of 32.3 ng·mg -1 of 1-OHP was found at Ústí nad Labem, while the lowest median value of 27.6 ng·mg -1 was found in the control site, Březenec. No significant differences (P < 0.05) among the sites were found. The highest concentration of PAH was detected in Litvínov-Záluží (172.0 ng·l -1 ) and the lowest concentration (7.9 ng·l -1 ) was detected in Březenec. A positive, but non-significant correlation (r s = 0.8) was confirmed between biliary 1-OHP and total PAH in passive samplers. These results indicate the highest pollution in the middle stretches of the Bílina River, especially at Litvínov-Záluží. We confirmed 1-OHP as the most prevalent PAH biliary metabolite in fish that could be used as a biomarker for assessment of PAH pollution of the aquatic ecosystem. The main importance of the present study is in the combination of biochemical and chemical monitoring that provides complex evaluation of aquatic environment contamination. It was the first study on the Bílina River, in which the assessment of PAH contamination in the aquatic ecosystem was realized using combination of biotic and abiotic monitoring. PAH, 1-hydroxypyrene, SPMD, river pollution, biomonitoringThe environment is continuously loaded by allochtonous organic chemicals that have been produced and, in part, released into the environment by urban communities and industries. The ultimate destination of many of these contaminants is the aquatic environment, either via direct discharge or due to hydrological and atmospheric processes. One group of important ubiquitous environmental contaminants are polycyclic aromatic hydrocarbons (PAH) that are formed mainly by incomplete combustion of organic materials such as fossil fuels, industrial activities, smoked food, and smoked tobacco (Van der Oost et al. 2003).Many vertebrate aquatic organisms are able to metabolize and excrete PAH rapidly. Since the elimination of PAH is generally efficient in fish, no bioaccumulation of these compounds in fish has been proved. Concentrations of PAH in fish tissue are therefore not indicative of the concentrations to which the animals were exposed and cannot be used as biomarker for exposure assessment (Van der Oost et al. 2003). Fish absorb PAH through the gills and body surface but they can be also exposed through ingestion of food or contaminated sediment (Vuontisjarvi et al. 2004). The liver is the major organ involved in PAH metabolism, and the metabolites produced are secreted into ...

“…A general observation is that the concentrations of these heavy metals did not have a seasonal variation feature and that the variation of the various heavy metals with time was very different. This indicates that the changes in these concentrations were mainly influenced by anthropogenic activities, rather than natural processes (Kohušová et al 2011;Li and Zhang 2010). The results show that the concentrations of As, Cr(VI), and Pb were much higher than those of Hg and Cd over this period.…”

From data collected monthly at 26 monitoring cross sections in the Wei River in the Shaanxi Region of China during the period 2008-2012, the temporal pollution characteristics of heavy metals (Hg, Cd, Cr(VI), Pb, and As) were analyzed based on a heavy metal pollution index (HPI). The monthly HPI values of the five heavy metals in the river fluctuated greatly in 2008 and then declined gradually with time. This general trend of reduction in HPI appears not to have a seasonal variation and most likely resulted from the continued improvement in heavy metal pollution control strategies implemented by local environmental agencies combined with a significant improvement in wastewater treatment capacities. Among the five heavy metals, Cd and Pb were below 0.1 and 3 μg L(-1), respectively, at all the sampling points in the studied areas in the year 2012. The detection rates of As, Hg, and Cr(VI) were in the order of Hg > Cr(VI) > As. Hg, Cr(VI), and As exceeded, in a month of the dry season in 2012, the standard limits for category III surface waters according to the China Environment Quality Standards for Surface Water (CEQSSW). Based on the assessment using the HPI method, the pollution status of these heavy metals in water of the Wei River in the Shaanxi Region was generally at an acceptable level, but exhibited distinctive characteristics between the main stream river and tributaries. Most of the tributaries were more seriously polluted than the main river. A health risk assessment was conducted based on the Human Health Risk Assessment (HHRA) method recommended by the United States Environmental Protection Agency (USEPA). Apart from As, the health risk for the five heavy metals in the region were at acceptable levels for drinking water sources (hazard quotient (HQ) < 1, carcinogenic risk (CR) ranged from 10(-4)-10(-6)) according to the Risk Assessment Guidance for Superfund (RAGS), USEPA. Arsenic was identified as the most important pollutant of concern among the five heavy metals; both its values of the HQ and CR indicated potentially adverse health risks for the local population.
