“…However, application of wastewater in agriculture may pose potential risks to the environment, as wastewater treatment plants have a limited capacity to remove organic chemicals (Bueno et al 2012). Moreover, the application of sludge or fertilisers on agricultural soils represents another source of organic contamination in soils (Vácha et al 2005(Vácha et al , 2006.…”

Ibuprofen is not completely removed in wastewater treatment plants, and consequently, it may enter the soil through irrigation with reclaimed water. Subsequently, due to the reversible adsorption which takes place in the soil, this emerging pollutant can become bioavailable for plants. The adsorption reversibility of this anti-inflammatory compound on four agricultural soils was quantified with adsorption-desorption experiments. The adsorption was found to be almost linear, with a minimum n ads of 0.76 and a maximum of 1.08. In contrast, desorption was nonlinear, with a n des which ranged from 0.84 to 2.75. The hysteresis index values were low, ranging from 0.42 to 0.66; hence the process takes place reversibly. In addition, ibuprofen was found to be moderately fixed in the soils studied, with organic carbon distribution coefficient (K OC ) values which ranged between 139.75 and 238.17 L/kg. Therefore, we conclude that this pollutant could be bioavailable for soil microorganisms or plants exposed to it and may reach groundwater by leaching.

“…In Europe, when sewage sludge is used in agriculture, the limits on the content of PAHs in naturally used municipal sewage sludge have been proposed [WD, 2000;WD, 2010]. Some of the EU countries have introduced internal limitation of PAHs contents in sewage sludge intended for use in agriculture [Aparicio et al 2009;Gomez et al 2002;Kapanen 2013;Langenkamp et al 2001;Vacha et al 2006]. In Germany, there are no binding regulations concerning the PAHs content in sludge, however, a designation of 9 PAH is recommended; the sum of which should not exceed 6000 μg/kg d.m.…”

, low-input methods such as composting, vermicomposting, reed beds, willow energy and solar driers are increasingly often being used in the processing of sewage sludge. The northeastern part of Poland has operated successfully for years using these methods. This paper presents the results of using low-cost methods of sludge treatment in the wastewater treatment plant located in Zambrow, Podlaskie Province. The results of sewage sludge studies on the PAHs and heavy metals content after treatment in a reed bed system are presented. Among the 16 examined PAHs, the lowest concentration was obtained for the dibenz (a,h)anthracene. Not a single sample exceeded a concentration of 100 μg/kg d.m. The highest concentration was exhibited by fluoranthene, benzo(g,h,i)perylene and indeno(1,2,3-c,d)pyrene. The concentration of these compounds exceeded 1000 μg/kg d.m. The obtained results for the PAHs in sewage sludge from the reed lagoon at the treatment plant in Zambrow showed that the average content of PAHs studied was approximately 8300 µg/kg d.m. The lowest concentration, below 1.3 mg/kg d.m. of the seven heavy metals examined was obtained for mercury (Hg). On the other hand, the highest concentration, exceeding 1300 mg/kg d.m. was found in the case of zinc (Zn). The obtained results for the heavy metals in sewage sludge from the reed bed lagoons in Zambrow show that the average content of heavy metals studied is approximately 1620 mg/kg d.m. The results of the study demonstrate a high efficiency of the low-cost methods used in the Zambrów WWTP in terms of the quality of processed sludge. The sewage sludge from the lowest layer of the reed lagoon (13-14 years of dewatering and transformation) are characterized by the lowest PAHs and heavy metals content. The higher a sediment layer lies, i.e. the shorter the time of processing, the higher are the PAHs and content of heavy metals content. This indicates a great role of reeds in the accumulation of these compounds.
