“…Both principal component analysis (PCA) and hierarchical cluster analysis (HCA) were carried out to group the variables (i.e., elements) based on the similarities of their sources. Similar kind of studies has also been performed earlier in India as well as other regions of the world [26][27][28]. The elements were grouped into three clusters in HCA (Fig.…”

“…Further, CV (%) was calculated for all the elements under consideration and the values indicated that the variation was least in case of Al content and highest in case of Cr content. Therefore, Al has been used as normalization/ reference element in the study [28].…”

“…Figure 4a represents [27] for the soil samples of the Singhbhum region of India. Enrichment Factors (EF) were determined to assess the degree of anthropogenic contributions of elements to the soils of area under study [26][27][28]. As in the results obtained from elemental analysis, Al content showed low variability, hence, Al was taken as a reference element in order to assess the expected effect of anthropogenesis on elemental accumulation.…”

The assessment of potentially toxic elements' contamination in surface soils of Kulsi River Basin in North East India has been studied based on the analysis of 50 soil samples collected from the basin. The average concentrations of Co (2.30 mg/kg), Ni (7.26 mg/kg), Pb (9.41 mg/kg), and Zn (22.7 mg/kg) surpassed the background levels prescribed for sedimentary rocks which indicated anthropogenic contribution of these metals. The average values of enrichment factors for different elements under study followed the order as Co > Ni > Zn > Pb > As > Fe > Cr. Results of multi-element indices revealed significant contamination at many sites; however, computed values for potential ecological risk index indicated only low ecological risk at all the sampling sites. The contribution of individual toxic elements toward the potential ecological risk followed the order as Co > Ni > As > Pb > Zn > Cr. The study recommends that suitable measures need to be taken for checking any further contamination in the area.

“…and/or the agricultural area's proximity to sources of soil contamination, such as industrial or urbanized areas, energy production infrastructure or landfills. Moreover, agricultural soil contamination is not only an environmental issue, since the potential transfer of contaminants from soils to crops can also pose a safety concern based on their risk to humans [7,8].…”

Potentially toxic elements (PTE) are considered to be dangerous threats, both for human health and the environment. Here, the contamination level, sources, and ecological risks posed by PTE were investigated in 19 topsoils from agricultural lands in the Bandar Abbas County on the southern coast of Iran. The soil fraction <63 μm was used for the analysis of the pseudototal contents of PTE (arsenic, cadmium, cobalt, chromium, copper, lead, manganese, molybdenum, nickel, vanadium, and zinc). The results were analyzed using principal component analysis (PCA) and Pearson’s correlations, different pollution indices [enrichment factor (EF), contamination factor (Cf), and modified degree of contamination (mCd), and the potential ecological risk index (PERI). The results of the pollution indices showed that the contamination levels of the studied agricultural soils are low to moderate, while the average PERI values indicate that the ecological risks of PTE range from low to high in the soils of the studied area. Correlations and PCA analyses suggest that studied elements have three possible origins: geogenic (chromium, cobalt, copper, manganese, vanadium, and zinc), anthropogenic (cadmium, nickel, phosphorus and lead) and atmospheric (arsenic) sources. These findings are helpful for the long-term assessment of PTE in the Bandar Abbas County.

“…Lacking of proper infrastructure to contain these anthropogenic activities, especially in the heavily populated areas, has led to several environmental problems (Nagajyoti et al, 2010;Alloway, 2012;Wu et al, 2016 andSteffan et al, 2017). Consequences include water and soil contamination by sewage and industrial wastes and the accumulation of heavy metals in agricultural soil and subsequently in various plantations (Zhou et al, 2016;Wang et al, 2017;Chen et al, 2018 andKhalifa andGad, 2018). These problems have also provided a better environment for pests and disease vectors to flourish and accordingly the use of pesticides has also intensified (Biswas, 1993 andEl-Nemr, 2017).…”

In Egypt and during the last 50 years, several changes in agricultural practices have affected different components of agro-ecosystems including weed flora. The aim of the present study was to evaluate changes in the weed flora of El-Menoufia Governorate, South of the Nile Delta of Egypt during the period from 1984 to 2018, in response to different agricultural practices. A total of 240 stands were investigated in both spring and summer seasons in order to document the present status of the weed flora. The obtained results were compared to results obtained by other authors in 1984. Results showed major shifts in the weed flora of El-Menoufia Governorate where 67 species out of 146 species were recorded in our study while only 42 species out of 121 species were present in 1984 survey. Changes in the family composition, life form, life span, and chorology were reported. Reasons responsible for such changes have been discussed. Changes in the crop composition, cultivation area of each crop, excessive use of fertilizers and pesticides, changes in irrigation water quality and quantity are the leading change promoters. The high economic importance of the weed flora and the potential threats facing agriculture in Egypt necessitate the formulation of a sustainable strategy for maintaining agro-ecosystems of Egypt and its biodiversity.
