“…The high levels of Cu and Mn accumulation north of Megres are linked not only to agricultural activities, but also to emissions from the large open-air landfill in the commune of Amoucha. This type of discharge generates toxic heavy metals associated with airborne particles [51][52][53][54][55]. This study is consistent with the results from other work, showing the positive relationship between the contamination of air with strong metals (Cu and Mn) and their bioaccumulation in lichens located near solid waste landfills [56][57].…”

The accumulating ability of the atmospheric Metal Trace Elements (MTE) of two lichenic species thalli; Xanthoria parietina and Ramalina farinacea were evaluated in the region of Megres. The recorded concentrations of MTE (Fe, Cu, Mn, Cd, and Pb) were determined by atomic absorption spectrophotometry (AASF). The ability to accumulate MTE in X. parietina thalli is considerably greater than that of the fruticulous lichen R. farinacea in all stations studied. The general pattern of the elements accumulated in the thalli of the two species in decreasing order of their concentrations was Fe> Mn> Pb> Cu> Cd. The Fe values are very high in X. parietina thalli with an average of 35237.5 ± 3394.2 mg/kg dry wt. In contrast, the Pb concentrations are high, especially in the southern station of the Megres region. The results showed that X. parietina is a hyper-accumulating species of MTE, compared to R. farinacea. This work highlights the ecological importance of this species as a stable and resistant pioneer in this fragile region.

“…One possible reason could be the high AN content in leachate from the Legnica landfill, which is indicated in the literature as one of the main causes of elevated toxicity [61]. The maximum values of AN in leachates from Legnica reached 786.1 mg/dm 3 .…”

The influx of toxic pollutants into wastewater treatment plants can negatively affect the quality of the activated sludge (AS). One source is landfill leachate. The identification of microorganisms present in AS is very important, e.g., while improving wastewater treatment technology. Therefore, the aim of the study was to investigate the effect of raw leachate and after purification of Phragmites australis and Ceratophyllum demersum on the composition of the AS bacterial biocenosis. In addition, AS status was assessed by LIVE/DEAD BacLight ™ fluorescent staining. The obtained results showed that the leachate did not significantly affect the cell membranes of AS bacteria, and even a slight improvement was noted. The research carried out using the next-generation sequencing method shows that the origin of the samples (active and closed storage) and the method of processing do not significantly affect the composition of the AS bacterial biocenosis at higher taxonomic levels. However, at the species level, the appearance of bacteria not previously present in AS was observed, namely: Flavobacterium luticocti, Candidimonas nitroreducens and Nitrobacter hamburgensis. The obtained results suggest that the leachate may be a source of microorganisms positively influencing the condition of AS bacteria.

“…The high toxicity of the leachates could be due to their high conductivity and the presence of heavy metals (Žaltauskaitė and Vaitonytė, 2016). The IC50 values for the immobilization of D. magna of the three leachates were Tema -2.3%, Mallam -29.5% and Oblogo -10.4% landfill.…”
