“…The percentage concentrations of these metals in the top and subsoil is in the order of Ni < Pb < Cd < Fe < Cr < Mn < Zn < Cu and Cu < Zn < Mn < Cr < Fe < Pb < Cd < Ni respectively. The concentration pattern of metals suggests a common trend in leaching and infiltration from the top to subsoil, input sources [20,36,37]. This is adduced to common; soil physicochemical characteristics, biochemical reactions within soil depths, reduced soils cohesion due to physical, biological, mechanical, and chemical factors, and vertical rather than the horizontal movement of metal mobility, thereby exposing bottom soil layers to contaminants [38].…”

“…Due to infiltration, diffuse and direct migration, and accumulation of pollutants, the unconsolidated nature of the sediments, abundant thick sandy sequence, and shallow water table of the study area, the observed concentration of metals may contaminate adjacent soils, ground and surface water resources in the monsoon season [10]. However, this scenario may be determined by the water chemistry and water-rock interaction [20,25,49,50]. In addition, based on the concentrations, duration, and routes of exposure, the observed Cd, Pb, Cr, Ni, Cu Mn, and Zn concentrations depict significant ecological and human health challenges if accumulated concentrations surpass the allowable standard values [51].…”

“…The water table varies from 0.7 to 10 m depth (in some areas, shallow dug wells serve as primary water supply), an atmospheric temperature of 23 to 28 o C, a subequatorial climate, high humidity, and long wet season.

This study provides a comparative assessment of cadmium (Cd), lead (Pb), chromium (Cr), nickel (Ni), copper (Cu), manganese (Mn), zinc (Zn), and iron (Fe) pollution occurrence, sources, and exposure risk in soils from selected abandoned sites. The concentrations of metals were determined using atomic absorption spectrophotometry. The metals occurrence ranged from 0.02 (Zn) to 16600 mg kg−1 (Fe) in the order of subsoil > topsoil with petroleum tank farm and fuel/gas service station exhibiting high metal loading. The sources of metals are anthropogenic and geologic. The hazard index values for infants’ were higher than that of adults, and the inhalation risk for adults’ was considerably higher than for infants’ exposure. The ecological risk of Cd, Pb, Cr, Ni, and Zn falls in the contamination to pollution index. This study revealed the need for clean-up and restoration of abandoned site soils.

The definition of terms and values of all variables are given [10] and [17] . Usually, HI value greater than 1 and TCR value greater than 1 x 10 -6 indicates the presence of adverse non-cancer and cancer risks respectively.…”

rganochlorine pesticides (OCPs) usage provides many advantages for agriculture; however, there are also significant concerns to the environment and public health. Since there is little information available on OCPs' distribution, associated risks and sources in Nigerian farmland soils, this study was carried out. Soil samples were collected from farmlands in ten communities. Samples were extracted with hexane/dichloromethane and cleaned up in a column of silica gel and florisil. The OCPs were measured using a gas chromatograph-mass spectrometry (GC-MS). The ∑20 OCPs levels in the soils varied between 47.5 and 109 ng/g. The OCPs homologues distribution in the soils was in the order of ∑DDTs > ∑Drins > ∑Chlordane > ∑BHCs > ∑Endosulfan. The risks assessment result indicated that there was adverse ecological effect on organisms residing in the soils and there is the likelihood that this effect will be frequently observed. Moreover, there was potential non-carcinogenic and carcinogenic risks for persons exposed to OCPs in these farmland soils. The result of the source identification indicated that historical usage was the main source of OCPs in these farmland soils.

“…Monitoring their residues in environmental and food matrices is crucial due to their persistence, bioaccumulation, and a range of negative effects on human and other animal health. 1 Therefore, there is an increasing call for the development of highly sensitive and selective methods for the determination of OCP residues, which are usually present in trace amounts.…”
