“…In the case of . It was assumed that only a small amount of metal passes through plants [20], however one should remember that the mechanisms of chromium resistance in plant cells have not been properly discovered and described [7]. Suggestion of World Health Organisation (WHO) indicated that the chromium concentration in plants growing in unpolluted soil should not exceed 0.19 mg·kg −1 [21].…”

“…Chromium(VI) compounds are usually highly soluble, mobile and bioavailable compared to sparingly soluble trivalent Cr species. [20,21] have reported an anomalous occurrence of Cr in soil samples surrounding the industrial zone. These studies are in agreement about the Cr(III)/Cr(VI) proportion in these samples being the dominant species Cr(III) and in a lower proportional Cr(VI).…”

Roadside soil samples were collected from four sites (heavy traffic area (Wurukum); industrial site (Gboko road); residential area (Federal Lowcost) and Federal Medical Center (Wadata) representing different activities across the Benue Metropolis. At each of the sample site, roadside soils were collected at different distance from the edge of the main road (2, 10, 30, 40 and 60 meters). In each of the distance, roadside soil were collected at three depth of 0 -1 cm, 2 -4 cm and 4 -6 cm for the determination of pH, organic matter, organic carbon, Cu, Cd, Fe, Pb, As, Mn, Zn, Cd and Ni. pH, electrical conductivity (EC), organic matter and organic carbon were determined using standard procedures, while heavy metals were determined using Perkin-Elmer Analyst 300 Atomic Absorption spectroscopy (AAS). Zinc was observed to show the higher levels in all the sampling sites, such higher level can be related back to the wear-and-tear of vehicle components as a result of the stop-start traffic patterns and brake pads. The concentrations of all the metals in the four sampling sites decreased exponentially with distance from the edge of the road and dropped to the minimum levels at about 60 meters. Similarly, mean concentrations of Cu, Fe, Pb, As, Mn, Zn, Cd and Ni were significantly higher around the industrial area (Gboko road) and heavy traffic (Wurunkum) areas than other sampling areas followed an increasing trend with the increase in depth. The vertical movement of all the metals, exhibited predominant association with soil pH and organic carbon. From the results of this study, the pH of the roadside soils from all the sampling points ranged from 4.56 to 7.71, which enhances increased of heavy metals down the soil profiles. Organic carbon content ranged of 0.27% to 5.44% across all the sampling points appears to increase the mobility of all the metals to a depth 6 cm. The values of the heavy metals suggest that automobiles and traffic activities are a major source of these metals in the roadside soil within the study area. Also, with the exception of Pb, Fe and Cd, the levels of Cu, As, Mn, Zn and Ni in the present study were lower as compared with results found by other researcher in various countries worldwide.

“…Quantities of magnesium oxide (MgO) in excess of about 2% by weight can occur as periclase, which through slow reaction with water, can cause destructive expansion of hardened concrete [31]. An excessive amount of chromium can directly lead to industrial problems [32]. In the China National Standards for Portland cement and ordinary Portland cement products, the content of MgO is limited to below 5% by weight, and for the chromium-containing raw materials for cement industry, the content of Cr 2 O 3 is limited to below 4.5% by weight [33].…”
