“…Total Nitrogen (Total N) of soil sample from Benin-Onitsha Bypass were relatively high and ranged from 0.03 to 0.08 mg/kg followed by Benin-Akure Bypass with values between 0.02 to 0.10 mg/kg compared to 0.02 to 0.05 mg/kg for the control. These observations are consistent with Agbeshie et al [33] in a tropical Nitrogen could be due to the addition of ash from the burning at the dump-site as opposed to no burning at control site [34]. Similarly, Available phosphorus content ranged from very low 2.07 to 21.12, 3.28 to 22.97 and 2.77 to 27.93 mg/kg for Benin-Akure Bypass, Benin-Onitsha Bypass and Benin-Warri Bypass.…”

A study on potassium dynamics and fractionation was carried out in Benin City to determine the amount and distribution of k fraction in soil samples collected from different refuse dumpsites. The sand, silt and clay contents of the dumpsites soils varied from 83.3 to 95.3, 0.60 to 3.35 and 2.55 to 15.10%, respectively. Soils were dominantly sandy with textural classes varying from sand to loamy sand down at depth. The result revealed that the water-soluble k and Exchangeable k range from 163.8 to 643.4 mg/kg in surface soils and 271.1 to 319.8 mg/kg in sub-surface in Benin-Onitsha Bypass and Benin-Warri Bypass. The difficult exchangeable k content ranged from 93.6 to 483.6 mg/kg and 50.1 to 467.9 mg/kg .in the surface and sub-surface of the dumpsites; K content was highest in the subsurface soils than in surface soils due to high deposition of refuse from surface soils within the dumpsites. In general, distribution of K forms decreased in the order reserved K > fixed > water-soluble > Exchangeable K, Structural K > Diff. Exch. K as well as the mobility factor for each of the refuse dumpsite investigated. Similarly, the amount of the various forms of k extracted decreased as the soil pH decreased. The soil samples collected far away from the dumpsites have lower concentrations of k forms compared to those from the vicinity of the dumpsites. This shows that the waste dumps had higher concentration of elements, thereby interacting with the soil and enhance their dominance within the dumpsites. The particle size fraction of the refuse dump suggests the need for consideration of active soil portions for sustainable K management of the environment.

“…This study results affirmed the previous studies [1,37] who reported that the leachates from solid wastes, significantly increased the soil heavy metals concentrations. According to Awokunmi [37], the concentrations of iron (3,000 mg kg -1 -5,000 mg kg -1 ), lead (3,500 mg kg -1 -6,860 mg kg -1 ), nickel (18 mg/kg -335 mg/kg) and cadmium (219 mg kg -1 -330 mg kg -1 ) recorded at the dumpsites soil samples, were significantly higher than the results obtained at the control location.…”

“…According to Awokunmi [37], the concentrations of iron (3,000 mg kg -1 -5,000 mg kg -1 ), lead (3,500 mg kg -1 -6,860 mg kg -1 ), nickel (18 mg/kg -335 mg/kg) and cadmium (219 mg kg -1 -330 mg kg -1 ) recorded at the dumpsites soil samples, were significantly higher than the results obtained at the control location. Agbeshie [1] reported that the iron, cadmium and lead concentrations of soil samples collected from a dumpsite in Ghana, were higher than the concentrations recorded in the control soil sample. The differences observed in the soil heavy metals concentrations between our results and other studies results [1,20], could be attributed to the sampling period, to the age of the dumpsite, transport mechanisms, remediation potential of the natural vegetation, locations at which the soil samples were sampled and organic materials present in the sampling location.…”

“…This proliferation of "unmanaged" dumpsites can lead to seepage of toxic substances (mostly heave metals) from the solid wastes leachates into the surrounding. Agbeshie [1] reported that leachate from solid waste in an unmanaged dumpsite is one of the major causes of heavy metals contamination of the environment. This is because, if the leachates from solid wastes in a dumpsite seeped into the soil and water bodies, they usually had significant negative impact on the plants and animals within the ecosystem.…”

The use of lowlands for refuse collection point (dumpsite) is a very common practice in Nigeria. However, people cultivated the areas within the vicinity of the dumpsites, without knowledge of the risk of these heavy metals. Therefore, this study was done to evaluate the risk of heavy metals pollution of soils within the vicinity of an active dumpsite. Four (4) soil samples (from 4 locations) at a depth of 0–20 cm were collected from the vicinity of the dumpsite. The heavy metals (e.g. iron lead, nickel and cadmium) concentration of the collected soil samples were analyzed according to American Society for Testing and Materials (ASTM) International methods. Pollution indices (contamination factor, enrichment factor, pollution load index and geoaccumulation index) were used to ascertain the level of heavy metals contamination of the dumpsite area. Results obtained from the soil tests revealed that, the dumpsite area had high heavy metals concentrations. The heavy metals concentrations were of this ranged: iron 3420 mg kg-1 to 4323 mg kg-1, lead 28.92 mg kg-1 to 58.84 mg kg-1, nickel 2.89 mg kg-1 to 6.91 mg kg-1, and cadmium from 1.04 mg kg-1 to 2.05 mg kg-1. The heavy metals concentrations ranked as Fe > Pb > Ni > Cd. Pollution indices results showed that cadmium had the highest contamination factor, enrichment factor, pollution load index and geoaccumulation index values, which portrayed that the dumpsite soil was heavily contaminated with cadmium. Results of the correlation showed a strong correlation (r = 0.87) between iron and nickel, indicating that the two heavy metals got their pollution from the source(s). Results obtained from this study will further help the government and environmental regulators to plan and carried out suitable remediation strategies, to clean the environment.

“…Domestic solid wastes can also harbour HMs, Bi et al (2018) reported higher concentrations of Cd, Zn, Pb, Hg, and Cu in the soil near municipal solid waste incineration plant in Shanghai, China. Similarly, dumpsite soil used for agricultural purposes in Sunyani, Ghana is contaminated with Fe, As, Cd, Pb, and Zn (Agbeshie et al, 2020). The acidic nature of the solid municipal waste (Sagbara et al, 2020) and the higher organic matter will favor HMs uptake by the plant (Liu et al, 2020).…”

The qualities of agricultural soil and water are diminishing continuously due to the rigorous anthropogenic activities currently stocking the soil with a lot of toxic chemicals including heavy metals. Heavy metals are highly persistent and non-biodegradable, control of their contamination is very tricky to handle. Their presence in soil and water is detrimental to food crops and humans. Various sources of heavy metals contaminants and the role of urban food production on human heavy metal contamination were discussed.Heavy metals have their way into the soil and food crops through wastewater irrigation and production in contaminated soil. The habitual heavy metals contamination sources for food crops are wastewater irrigation, abuse of agrochemicals, production in the contaminated field, atmospheric deposit when foods are exposed to contaminated air, and unethical mining activities. Agricultural soil in urban and peri-urban areas are heavily contaminated with heavy metal due to various anthropogenic activities. Wastewater irrigation intensify the contamination by supplying the soil with more heavy metals. The heavy metals are passed to food during production and subsequently to humans after consumption.
