“…The mean concentration of the trace elements in the subsoil, granite gneiss and pegmatite and the mean concentration of some trace elements in soils of published researched works, particularly in agricultural and urban soils in Nigeria are presented in (Darwish and Pollmann, 2015) as well as top and sub soil of Ile -Ife area (Asowata and Akinwumiju, 2020). The mean concentration of Pb in the subsoil in this study is found to be slightly higher compared to soil of Agricultural Sites in Sri Lanka (Jayawardana et al, 2013). And the mean Pb concentration, from this study, is signi cantly lower compared to the data from other soils in Egypt, Sri Lanka, among other areas of comparison (Table 5).…”

Trace elements (TE) concentrations of subsoil and the underlying parent rocks of Labunwa – Odele area were determined in other to ascertain the enrichment level, distribution and sources of these TEs in the subsoil in the study area. Twenty-one (21) subsoil (at depth of 30 -100 cm) and thirteen (13) rock samples were collected, pulverised and digested using aqua regia for soil samples and near total digestion of HClO4, HF, HCl and HNO3of different proportions for the rocks. The samples were analysed using Inductively Coupled Plasma- Mass Spectrometry, (ICP-MS). The mean TE concentrations in ppm for subsoil showed Cu (40.0), Pb, (24.2), Zn (56.3), As (0.9) and U (2.7) among other elements as against the mean concentrations of granite gneiss (GGN) with Cu (22.9), Pb (61.4), Zn (64.6), As (1.0), U (2.6) and Pegmatite, (PGM) Cu(128.4), Pb(17.0), Zn(108.8), As (1.1), U (1.3) among other TEs. The relatively low concentrations of the TEs in the subsoil compared to the underlying parent rocks suggests that TEs in the subsoil may have been influenced by geogenic factors, such as weathering of the underlying rocks. TEs source apportionments in the subsoil using Bivariant plots, correlation coefficient, Bi-polar and dendogram analyses showed that these TEs are essentially from the underlying GGN and PGM in the area. Pollution status indices, I-geo, Contamination factor and PLI showed that the study area is practically unpolluted. This suggests that locations with relatively higher concentrations of some TEs are probably due to mineralisation and since most of the subsoil TEs are significantly lower in concentrations compared to the underlying bedrock, the area is safe for agricultural activities.

“…The resultant data base was interpreted to develop a soil classication method that could be used to constrain the depositional environment of the alluvial sediments. Jayawardana et al 168 used XRF spectrometry to measure the major and trace elements in agricultural soils from North-central Sri Lanka in a study designed to identify whether there were any links between the presence of contaminants and health hazards (such as chronic kidney disease) found in the area. Their results indicated that there was no signicant threat from As and most other trace elements, but that there was a potential environmental risk from Pb and V due to their signicant enrichment in soils.…”

“…Mining, fossil fuel burning, use of arsenic fungicides, herbicides and insecticides in agriculture are considered to be the main anthropogenic sources and activities in groundwater contamination, with As (Shankar et al, 2014;Akter and Ali. 2011;Jayawardana et al, 2014). In Chile, Mexico, China, Argentina, the United States, and Hungary and even in the Indian State of West Bengal, Bangladesh and in Vietnam, high level of As in groundwater has been well documented.…”

Heavy metal contamination in food crops and ground water lead toxic effects on living organisms through the interference of the metabolic pathways. In this paper, the prevailing scientific data, with regard to the accumulation of heavy metals in groundwater and food crops in Sri Lanka, were reviewed. Evidence revealed that the groundwater bodies in Sri Lanka are in safer level to be used for day-to-day activities with a few exceptions and however, the heavy metal accumulation in some food crops are beyond the permissible level. Chronic Kidney Disease of unknown aetiology is one of the emerging issues at present in dry zones, particularly in the North Central Province in Sri Lanka and its suspected due to the extensive use of agrochemicals which is believed to be contaminated with the heavy metals.
