“…As far as the studied soils, the content of bioavailable forms of lead in the soils of Kielce was higher than in Olsztyn, comparing to the content of total forms. The analysis of the percentage share of bioavailable forms in the total content of lead did not clearly confirm the conclusions made by Papazotos et al [52].…”

“…Papazotos et al [52] showed in their study on the soils of Athens that the higher the total content of this metal in the soils, the lower the level of extraction of exchangeable forms. As far as the studied soils, the content of bioavailable forms of lead in the soils of Kielce was higher than in Olsztyn, comparing to the content of total forms.…”

Kielce and Olsztyn are two different urban ecosystems. They differ from each other in terms of geological and climatic conditions, as well as spatial development and industrial past. The aim of this article is to assess and compare the degree of lead contamination of the natural environment in both cities based on the conducted tests of soils, as well as a common dandelion’s roots and leaves. For this study’s purpose, 60 samples of soils and common dandelion’s roots and leaves were collected in each city, according to four land-use types, namely industrial areas, urban green areas, urban allotment gardens, and urban forests. Basic physico-chemical properties and concentrations of lead, i.e., total content and bioavailable content were determined in the soils, using speciation analysis. Lead concentrations in the roots and leaves of common dandelion were, in turn, determined using the ICP-OES method. By using kriging models, spots with excessive lead concentrations differing from the geochemical background were identified in each city. The number of spots was comparable for both cities; however, the values for this metal differed significantly. No relationship has been found between land-use types and concentrations of lead in soils and common dandelions. The results of the study, as well as statistical and spatial analyses show that this species may be recommended as an indicator for biomonitoring of urban environments.

“…Pb is a toxic metal to humans, causing carcinogenic impacts and teratogenic abnormalities in humans, even at very low concentrations (32,28) . The high concentration of Pb recorded in QAE (1449, 27 μg L-1) may be due to the nature of anthropogenic activities connected with oil products and traffic (33,34) , the release of unsuccessfully treated waste effluents and Pb-containing pesticides. These results were therefore consistent in the rainwater samples analyzed (27,35) .…”

Air pollution has regarded as one of the most significant environmental problems, due to its direct impact on ecosystems and human health. Economic and industrial development has increased urban atmospheric pollution, especially in developing nations. This research conducted to rate the rainwater quality in different areas of Basrah city. Using biota and rainwater samples carried out on Environmental monitoring of selected metals. From five locations collected samples (Khor Al-Zubair, Al-Zubair district, Basrah City Center, Abil Khaseeb district, and Garma Ali area). Results showed a significant difference in concentrations of trace metals levels between rainwater and date palm (Phoenix dactylifera L.) and Cordia myxa plant leaves and discovered in the following order: Fe > Mn > Cu > Pb. The soluble ions in rainwater followed the following order:− . Vehicles, industry emissions, and waste burning are the main anthropogenic sources of ions and metals. According to WHO standards, concentrations of trace metals have been found in the study areas above the acceptable limits in the sample of both plants. These findings show that special attention should pay to this environmental issue and that these emission levels should cut.

Cassava as a food is widely eaten in nearly all tropical countries. This has led to the emergence of many cassava processing centres, which consequently results in extensive ecological pollution due to the release of cassava processing wastewater into the environment. Wastewater treatment is mostly carried out using chemical coagulants, which are not environmental friendly. This study aims at providing non-chemical based alternative treatment procedures for cassava wastewater. The treatment procedures involved the use of alum and Moringa oleifera seeds as coagulants. The coagulants were used in combination with sodium hypochlorite at 25 and 50 mg/L for coagulation periods of 24 h and 48 h. Physicochemical parameters including, pH, biological oxygen demand (BOD), cyanide, coliform count and heavy metals [Ni, Zn, and Cr] were evaluated for both raw and treated wastewaters using standard methods. The data obtained were subjected to descriptive and inferential statistics. At 50 mg/L dose and 48 h coagulation period, the removal efficiencies of cyanide were 98.91% and 99.63% for alum and M. oleifera seeds, respectively. M. oleifera seeds reduced coliform in the effluent by 96.73% and decontaminated heavy metals [Ni, Zn, and Cr]. However, none of the two treatments could reduce BOD to a permissible level. The study concluded that M. oleifera seed is a potential coagulant, and could therefore be used as a substitute to synthetic coagulants.
