“…The highest enrichment factor of Zn metal was determined in near road sample of Z.mays while the lowest concentration was present in away road sample of B. compestris of site 2. Sulaiman and Hamzah, reported the enrichment factor of Pb and Cd which was lower as compared to the current study [51]. The enrichment factor of Pb in the present study was higher.…”

Due to increasing population and increasing number of automobiles the fodder samples were collected from Khushab District along the roadside to examine the heavy metal contamination. It was a serious issue because animals consume these contaminated fodders and then they enters the food chain where they cause toxicity. Five fodder plants Pennisetum glaucum, Trifolium alexandrinum, Saccharum officinarum, Zea mays and Brassica compestris were selected for sampling. The sampling of selected fodder plants and their soil was done during November which was the driest season of Khushab city and the dust and smoke was present on the fodder plants. The samples were air and oven dried. Then subjected to digestion. Acid digestion was done with Nitric acid (HNO3), Hydrogen peroxide (H2O2) and Hydrogen chloride (HCL). The samples become transparent and the heavy metal analysis of both soil and fodder samples was done through Atomic absorption spectrophotometer (AASP). Lead and zinc heavy metals were analyzed. The pollution load index was lower than 1 which indicates that there was low concentration of metal in soil of the collected samples of the current study. It was obtained that the soil was less polluted. The daily intake of metals was lower than 1 that concluded that they were at safe limit during consumption. The present study showed the enrichment concentration of metals greater than 1 it means these metals were present in both soil and fodder samples growing near roadside.

“…Metals can be transferred from soil into plants through the roots in the form of dissolved ions via a series of complex processes [11]. The accumulation of contaminants in plants can be estimated by the metal mobilization from soil to plant or known as bioconcentration factor (BCF) [12][13][14]. Previous studies have discovered high metal enrichment in leafy vegetables, followed by tubers and fruits [15][16][17].…”

This study determines the toxic heavy metal (As, Cd, Pb) concentrations in selected leafy vegetables (pak choi, amaranth, and caisim) that were collected from an agricultural area in Jengka, Pahang, Malaysia. A potential health risk via the ingestion pathway is also evaluated. A graphite furnace atomic absorption spectrophotometer (GFAAS) analysis was applied to determine metal concentration. Heavy metal concentrations for leafy vegetables ranged between 0.03 and 0.05 mg/ kg for lead (Pb), followed by 0.19-0.43 mg/kg for arsenic (As) and 0.15-0.54 mg/kg for cadmium (Cd). Cd is likely to be accumulated and absorbed more than arsenic (As) and Pb based on the bioconcentration factor (BCF). Cluster analysis (CA) and principal component analysis (PCA) suggested the metal origin is anthropogenic (the agricultural activities). Target hazard quotient (THQ) value below unity (< 1) indicates low non-carcinogenic risks of Cd and Pb. However, the high lifetime cancer risk (LCR) values for As and Pb (LCR > 1 × 10 -4 ) possibly will pose a health risk to consumers. This study suggested leafy vegetable intake from this area poses some degree of potential health hazards to the consumer. Therefore, a comprehensive investigation such as bioavailability metal form analysis to obtain a more accurate risk assessment is needed.

“…Iron was the most abundant metal in soil in the industrial zone. Sulaiman and Hamzah [20] reported that heavy metal concentrations in roadside plants were higher than in the same species from uncontaminated sites. Metals in the root were only weakly transported to the stem but more strongly mobilized to leaves when available in the stems.…”

“…These secondary metabolites, in particular polyphenols, are of particular importance in plant-environment relationships [19]. High concentrations of metals in plants can also inhibit chlorophyll production, increase oxidative stress, and weaken stomata resistance [20].…”

Anthropogenic pollution can take various forms and affect the air, water, soil, and plants. Monitoring pollution via compounds formed in living organisms such as plants, so-called bioindicators, may be a useful approach for environmental monitoring. The purpose of this study was to investigate and compare plants growing in industrial and residential areas of Sadat City, Egypt, as bioindicators and biomarkers of industrial pollution. Phenolic compounds, flavonoids, and metals were measured in Bougainvillea glabra (paperflower) leaves by HPLC-MS, neutron activation analysis, and atomic absorption spectrophotometry. Air, water, and soil samples associated with B. glabra sampled in industrial and residential areas were also analyzed for the presence of phenolic compounds, flavonoids, metals, and particulate matter. There were significantly higher levels of flavonoids and phenolic compounds in the leaf extracts of plants growing in industrial areas compared to those growing in residential zones (P<0.05). Metal accumulation in leaves was also significantly higher in the industrial zone than the residential zone: iron, lead, zinc, nickel, and manganese were present at significantly higher levels in plants in the industrial zone compared to those growing in the residential zone (P<0.05); nevertheless, the concentrations of heavy metals in the air, water, and soil were under local legal environmental limits. This study demonstrates that pollution has significant effects on total phenolic, flavonoid and metal levels in B. glabra plants, not only demonstrating the effects of pollution on ecosystem health but also paving the way for using plants as bioindicators and for phytoremediation.
