“…The so-called PCA dimensionality reduction technique was used to get more information about geochemical symmetrical elements and their origin. The data was centered log-ratio transformed CLR prior to the implementation of PCA (Badawy et al, 2018;Faith, 2015). The obtained PCAs were plotted and partitioned into clusters using K-means method.…”

The present work was conducted to characterize and monitor the air quality in terms of pollution and toxicity impact using two evergreen tree leaves, Eucalyptus globulus Labill and Ficus benjamina L. as biomonitors. Thirty tree leaves and an equal number of co-located soil samples from different regions of Egypt (urban Greater Cairo Metropolitan GC and rural Menoufia Governorate MG) were collected. The concentrations of 34 and 40 elements were determined using instrumental neutron activation analysis and atomic absorption spectrometer. Bivariate and multivariate statistical analysis were implemented. The air pollution was assessed using enrichment factor, pollution load index, potential ecological risk, and risk index. In addition, human and ecotoxicity were evaluated based on the ReCiPe method. The mean concentration values of the obtained elements in tree leaves in urban Greater Cairo and rural Menoufia Governorate show that the major elements are slightly higher in F. benjamina than in E. globulus. Likewise, the mean values of elements in soil from Greater Cairo and Menoufia Governorate show no significant difference except for major elements (Fe, Al, Mg, K, Na, and Ti) in Menoufia Governorate. The normalized concentrations of tree species and soil show that the accumulated elements by F. benjamina is slightly higher than in E. globulus in Greater Cairo GC and Menoufia Governorate MG. While in terms of the investigated area, the concentrations of elements in MG is considerably higher than in GC. PLI spatial distribution over investigated areas showed that despite high population density, heavy traffic, and urban pollution, the Cairo samples exhibit significantly lower values as compared to those from Menoufia, which is most likely due to the uncontrolled industrial and domestic waste disposal outside Cairo. PER was significant for As in Soil and for As and Cd for tree species. Human toxicity shows higher values in urban locations. Contrariwise, in the terrestrial ecotoxicity aspect, the rural locations are much higher than in urban ones.

To assess the vulnerability of Araromi residents to toxic (trace) metal pollution, we estimated the ecological risk of the sediments in the coastal area. The concentration of the metals (ppm) followed the trend: Fe (16,265-90,512) > Mn (116.3-1657) > Zn (16.5-338) > Cu (2.62-75.5) > Cr (4.5-29.25) > Pb (2-104.5) > Co (2.5-26) > Ni (1.45-22.75) > Cd (0.0015-1.5). Sediments from Oke Siri-2, Idi Gbengben-1, Oke Meji, Idi Gbengben-3, and Ola Baba evidenced significant or extremely high enrichments. The degree of pollution of the trace metal was Pb > Cd > Zn > Fe > Mn > Co > Cu > Cr > Ni.Furthermore, the derived geoaccumulation index and contamination factor revealed that Pb, Cd, and Zn exhibited low-high pollution levels. In contrast, Cr, Ni, Cu, Mn, Fe, and Co showed zero potential for ecological risks. The hazard index suggested that children and adults were not susceptible to any potential carcinogenic and noncarcinogenic effects. Also, the consensus-based sediment quality guidelines revealed no adverse effects caused by toxic metals as the metals have values below the probable effect concentrations.
