Heavy metals' data in soils for agricultural activities

Abstract

In this article, the heavy metals in soils for agricultural activities were analyzed statistically. Ten (10) soil samples were randomly taken across the agricultural zones in Odo-Oba, southwestern Nigeria. Ten (10) metals; namely: copper (Cu), lead (Pb), chromium (Cr), arsenic (As), zinc (Zn), cadmium (Cd), nickel (Ni), antimony (Sb), cobalt (Co) and vanadium (V) were determined and compared with the guideline values. When the values were compared with the international standard, none of the heavy metals in the study area exceeded the threshold limit. However, the maximum range of the samples showed that Cr and V exceeded the permissible limit which could be associated with ecological risk. The data can reveal the distributions of heavy metals in the agricultural topsoil of Odo-Oba, and can be used to estimate the risks associated with the consumption of crops grown on such soils.

“…In pot experiments, the toxic effects of Cd are more complicated, because Cd and other elements have interacted [78]. The background value of the soil in our experiment was much higher than in other studies [79,80], and the Cd content of the non-irrigated soil group has exceeded the threshold requirement for growing crops [81,82]. The above defects are due to the purchase of nutrient soil that does not meet the expectations of the experiment through a commercial company.…”

Heavy metal analysis in the soils of in and around Robe town, Bale zone, South Eastern, Ethiopia

“…The organic carbon content of the soil samples were determined by loss on ignition method (Maguire and Heckendorn, 2005). Soil heavy metal analysis Heavy metals (Fe, Zn, Cu, Pb, Cr and Cd) in soil samples were analyzed using aqua regia digestion method and determined by flame atomic absorption spectrometer at Ezana mining laboratory as described in the manufacturer's instruction manual after the digestion procedure (Ščančar et al, 2000;Adagunodo et al, 2018).…”

Accumulation, temporal variation, source apportionment and risk assessment of heavy metals in agricultural soils from the middle reaches of Fenhe River basin, North China

“…Previous studies have only focused on the contribution of HM sources to health risk. [28][29][30][31][32][33][34][35] However, exposure of both ecosystem and human beings to HMs can be harmful, 36,37 and thus evaluation of the contributions of different HM sources to ecological and human health risks is important but has rarely been explored in previous studies.…”
