The recommended maximum contents of the substances from the group of persistent organic pollutants (POPs) in sludge for the application on agricultural soils were proposed. The list of the substances follows Czech legislative norms for soil protection (Directive of the Ministry of Environment No. 13/1994 Sb.). The list includes the groups of polycyclic aromatic hydrocarbons (PAHs), monocyclic aromatic hydrocarbons (MAHs), the amount of six congeners of polychlorinated biphenyls (PCB<sub>6</sub>), DDT and residues, polychlorinated dibenzo-p-dioxins and dibenzofuranes (PCDDs/Fs). Recommended maximum contents were proposed on the basis of the determination of background values of POPs in the set of 45 sludge samples from the wastewater factories in the territory of the Czech Republic. The results of vegetation experiments focused on the POPs in soil and plants after sludge application were used and the proposal of EU legislation Working Document on Sludge was investigated.

The aim of this study was to identify and examine the levels of organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) in soil collected from the surroundings of historical pesticide storage facilities on former agricultural aerodromes, warehouses, and pesticide distribution sites located in the most important agricultural regions in Azerbaijan. The conducted research included determination of three groups of POPs (occurring together), in the natural soil environment influenced for many years by abiotic and biotic factors that could have caused their transformations or decomposition. In this study, soil samples were collected in 21 georeferenced points located in the administrative area of Bilasuvar, Saatly, Sabirabad, Salyan and Jalilabad districts of Azerbaijan. Soil chemical analysis involved determination of organochlorine compounds (OCP): hexachlorocyclohexanes (HCHs) (three isomers α-HCH, β-HCH and γ-HCH) and dichlorodiphenyltrichloroethanes (DDTs) (six congeners 2,4′DDT; 4,4′DDT; 2,4′DDE; 4,4′DDE; 2,4′DDE; and 4,4′DDE); polycyclic aromatic hydrocarbons (PAHs): 16 compounds from the United States Environmental Protection Agency US EPA list and, PCBs (seven congeners identified with the following IUPAC numbers: 28, 52, 101, 118, 138, 153, and 180). Our research showed that OCPs reached the highest concentration in the studied areas. The total concentrations of OCPs ranged from 0.01 to 21,888 mg∙kg−1 with significantly higher concentrations of Σ6DDTs (0.01 μg kg−1 to 21880 mg kg−1) compared to ΣHCH (0.14 ng kg−1 to 166.72 µg kg−1). The total concentrations of PCBs in the studied soils was varied from 0.02 to 147.30 μg·kg−1 but only PCB138 and PCB180 were detected in all analyzed samples. The concentrations of Σ16 PAHs were also strongly diversified throughout the sampling areas and ranged from 0.15 to 16,026 mg kg−1. The obtained results confirmed that the agricultural soils of Azerbaijan contained much lower (up to by three orders of magnitude) concentrations of PCBs and PAHs than DDT. It is supported by the fact that PCBs and PAHs were not directly used by agriculture sector and their content results from secondary sources, such as combustion and various industrial processes. Moreover, the high concentrations of PAHs in studied soils were associated with their location in direct neighborhood of the airport, as well as with accumulation of contaminants from dispersed sources and long range transport. The high concentrations of pesticides confirm that deposition of parent OCPs have occurred from obsolete pesticide landfills.

In this paper, 34 soil samples was collected in Beihu Lake area in Wuhan, Hubei province for determination of 16 types of polycyclic aromatic hydrocarbons (PAHs), in order to study the residues of persistent organic pollutants in soil of Beihu area, GC-MS, as well as a detection method called EPA8080A, was used to detect these PAHs, including Naphthalene, Acenaphthylene, Acenaphthene, Fluorene, Phenanthrene, Anthracene, Fluoranthene, Pyrene, Benzo(a)anthracene, Chrysene, Benzo(b)fluoranthene, Benzo(k)fluoranthene, Benzo(a)pyrene, Indeno(1,2,3-cd)pyrene, Dibenzo(a,h)anthracene and Benzo(g,hi)perylene. The result showed that PAHs could be found in all the samples, and the average residue of PAHs was 4114.2 ng/g. The coefficient of variation was 0.98, which indicated a greater dispersion. The pollution was more serious in the specified district than other domestic and foreign area. The ratio of specific PAHs demonstrated that they mainly came from combustion process and then fall to the surface by means of atmospheric deposition, thus, the departments concerned should strengthen or improve the use of fuel.

A set of 45 samples of the sludge from wastewater factories in the area of the Czech Republic was completed. The selection of wastewater factories reflected the extent of observed area as well as the occurrence of the industrial wastewater. The contents of persistent organic pollutants (POPs) were determined in the samples. Moreover, the contents of polychlorinated dibenzo-p-dioxins and dibenzofuranes (PCDD/F) were detected in 16 samples. The set of analytical data summarises the level of sewage sludge contamination by POPs within Czech wastewater factories. The results were compared with the directive of Czech Ministry of Environment, No. 382/2001 Sb. and with the proposed limit values of the EU directive, No. 86/278. Among all the determined substances only the value of the sum of polycyclic aromatic hydrocarbons (PAHs) content exceeded the threshold value given by the proposed EU directive.
