“…As observed in groundwater, pH and EC concentration in soil are lower in active soils (i.e., soils from the area of study) than in control and decreased with depth in both soils (Table 4). pH does not have adverse effect on plant growth even though both soils are within the permissible limit in terms of DPR (2002) pH standard (Gentili et al 2018). EC reflects the sum of salts and ions in the soil solution (Bronson et al 2005;Sudduth et al 2005;Peralta and Costa 2013).…”

Results from the assessment of physicochemical qualities of groundwater and soils around Afam in Niger Delta done using, statistical model, geo-accumulation indices (I-geo) and water quality indices showed that pH and Cu did not correlate strongly with any of the parameters analyzed in the study area. At 2-tailed of 0.05 levels of significance, moderate correlation exist between dissolved oxygen and Ca > Na, strong to moderate correlation exist between temperature and total dissolved solids (TDS) > E.C > Na and Ca, whereas at 2-tailed level of 0.02, very strong correlation exist between E.C and TDS (0.988), > Na (0.966), > Ca (0.957). TDS in turn is strongly correlated with Na (0.987), > Ca (0.972). Fe, Zn, Pb and Cr, total petroleum hydrocarbon (TPHC), oil and grease (O&G) (< 0.001 mg/l) did not correlate with any of the physicochemical elements in the samples. At 2-tailed levels of 0.02 and 0.05, no significant correlation exists between alkalinity and salinity in groundwater samples and also with any the elements. Groundwater showed excellent water quality except one (62.307). pH, Cr, Fe, Ni, Pb and Cu in the soil were unpolluted since I-geo values are less than 1. Polycyclic aromatic hydrocarbon (PAH) (2.5194) showed low pollution, O&G (3.8886) showed moderate pollution, while total hydrocarbon content (THC) (6.2069), total organic carbon (TOC) (7.4919) and TPHC (9.4851) showed extreme pollution. The control site appeared to be unpolluted except TOC (6.8721). Percentage of clay particles in the soil is higher than in control.

“…A multivariate correlation of heavy metals tested in the soil sample were carried using Pearson correlation coefficients at two-tailed test of 0.02 and 0.05 levels of significance with the aid of SPSS. In this study, the higher the value is, the stronger the correlation of the heavy metals to each other [45,46]. Here, correlation coefficients > 0.7 is considered as strong correlation, < 0.7 ≥ 0.5 moderate while < 0.5 is considered as weak correlation.…”

Heavy metals pollution in soils has become a serious threat to many countries especially developing countries like Nigeria due to increase in urbanization and industrialization. In this study several indexical models (contamination factor (CF), contamination degree (mCd), geo-accumulation index (Igeo ), pollution load index (PLI), and Nemerow integrated pollution index (NIPI)) were used to assess the pollutions, pollution sources and ecological effect of heavy metals (Fe, Zn, Pb, Cd, Mn, Cu, Cr, and Ni) in industrial soils from Ajao area, Lagos. All the metals are within the standard of Department of Petroleum Resources (DPR) except Cd (1.160, 1.020, and 1.080) mostly around the industrial wastewater dislodging Point. Pb has no significant correlation with other heavy metals in the soil samples whereas other heavy metals, strong to medium positive correlation exist between these heavy metals at 2-tailed significant levels of 0.01 and 0.05 suggests that these metals have the same anthropogenic origin. The 1-geo calculated for heavy metals suggest that all the samples are unpolluted. CF of the heavy metals was in the range of low contamination except Cd that showed moderate contamination. RI∑ of all the heavy metals analysed in this study pose low ecological risks except for Cd which showed moderate potential to considerable potential ecological risk. NIPI result showed some of the samples were slightly polluted while some were heavily polluted. For mCd, all the samples were within very low degree of contamination. The PLI result shows that samples were within unpolluted range in the PLI classification scheme.

“…The phases of volcanic activities involved in the formation of Plateau State have made it one of the mineral richest states in the country [25]. In Plateau State, tin (Sn), cassiterite and columbite are present in veins and pegmatites associated with rhyolites and granites intrusion, and can also be found in metamorphic rocks [26]. When the rock containing minerals are weathered, they remain intact and eventually concentrated in streams to form placer deposits [27].…”

This study investigated the geotechnical properties of tin mine tailings for its potential use, using particle size analysis, oedometer consolidation test, quick undrained triaxial test, compaction test and permeability test. The results showed that tailings from Caha1 and Kantoma1 have higher percentage of coarse than fine grains, lower moisture and optimum moisture content and higher coefficient of permeability. The most well graded materials of the mine tailings is CahaC. KantomaC and CahaC showed higher percentage of fines, high plastic, liquid and shrinkage limit, high plasticity index, high moisture content and optimum moisture content, higher shear strength, and lower coefficient of permeability. However, compression and swelling index of all the tailings are of low plastic clay and have very low swelling potential. Based on degree of plasticity, all the mine tailings in the study area are below the range of 1-5 hence, they are non-plastic material.
