“…However, the efficiency of plants in absorbing metals is determined by either plant uptake or soil-to-plant transfer factors of the metals. Plant tissues absorb and accumulate heavy metals based on the available pH, moisture content, temperature, organic matter, and nutrient [64]. Table 2 shows some risks associated with food chain contamination for humans and some trophic levels in Nigeria.…”

Heavy metals such as Zn, Pb, Fe, and Cu are abundant in the environment and contribute largely to the sustainability and equilibrium of ecosystem processes. However, because of their bioaccumulation, nondegradability, and the excessive amounts in which they exist, these metals contaminate the food chain and subsequently become a source of toxicity to human beings and the entire ecological function. This is a major issue of concern within the study of environmental science and geochemistry. Although there is a global significance to the issue, it seems more immediate for the developing countries (DCs) such as Nigeria, where the pressure of the teeming population escalates the exigency for human sustainability, food security, and total eradication of hunger. Within the Nigerian context, many studies have examined this all-important issue, but most of these studies are fragmented and limited within the purview of mostly individual states and localities within the country. Taken on a wider geographical scale, the discussions and perspectives of these studies on heavy metal contamination of the food chain offer insufficient insight and expose merely a snapshot of the actual situation. As a result of this, a country-wide knowledge base of the implications of heavy metals on the food chain is lacking. Thus, the present study synthesises existing literature and their findings to create a knowledge base on the vulnerability of the food chain in Nigeria. Aquatic foods, fruits, vegetables, and major staple food such as tubers are the major host of carcinogenic and mutagenic components of heavy metals in Nigeria. This study motivates the Standard Organisation of Nigeria (SON), along with other food and agricultural agencies, to intensify their efforts in monitoring and analysing food components, and we advise consumers to eat with certain degrees of caveat.

“…The atmosphere can be loaded with heavy metals through the breakdown of applied waste materials, which gradually release the heavy metals in them. However, lead accumulation on Nigerian soil is a result of long-term cultivation [15], while a significant increase in the concentration of zinc in pasture fields is due to the application of manure [16].…”

Heavy metal contamination of food crops is an issue of global concern that ultimately results in toxicity and diseases in humans and animals through consumption of contaminated soils and food crops. With a population of 182 million people, Nigeria is regarded as the most populous country in Africa. The people suffer environmental pollution from high levels of heavy metal accumulation in the environment and in food crops. Heavy metals have atomic densities higher than 4 g/cm3, and these include lead (Pb), cadmium (Cd), zinc (Zn), mercury (Hg), arsenic (As), silver (Ag), chromium (Cr), copper (Cu), iron (Fe), and platinum (Pt). The high level of environmental contamination by these metals is dangerous because their uptake by plants and subsequent accumulation in food crops consumed by humans and animals is deleterious to health. There are many known sources of harmful metals, including the earth, which releases them into food, air, and water, and anthropogenic activities, such as the application of fertilizer in agriculture, the use of pesticides and herbicides, and irrigation. Other sources are automobile emissions, paints, cigarette smoking, industries, and sewage and waste disposal. Evidence shows that vegetables and other food crops consumed in Nigeria are contaminated by heavy metals, and this is associated with adverse health issues, such as cancer, which is currently on the rise in Nigeria. It is therefore vital that communities with high levels of heavy metal pollution avoid eating large quantities of these food items. There is also the need for the monitoring of levels of these injurious elements in food crops.

“…This soil is with sandy clay loam B t horizons with a depth to the mottled parent material normally more than 150 cm. The texture of the surface soil was 86% sand, 8% silt and 6% clay whiles that of the subsoil was 65% sand, 6% silt and 29% clay; the bulk density was 1.45 and 1.57 g cm 3 respectively (Anguelov and Anguelova 2009). Orangeburg soils have high to moderate moisture holding capacity, medium surface runoff and medium internal drainage with moderate-rapid permeability (saturated hydraulic conductivity, Ks = 4.4 cm h -1 ) in the surface layer and moderate permeability in the subsoil (Ks = 1.5-2.2 cm h -1 ).…”

Land use management is important to maximize nutrients use efficiency and reduce losses, especially on sandy soils. Nutrient cycling in pastoral systems is different as the grazing animals are excreting back to the pasture most of the ingested nutrients. The objective of this study was to evaluate N, P, K, Ca, Mg, and Na by monitoring elements' concentrations in soil solution from bahiagrass (Paspalum notatum Flugge) pastures continually-stocked with cattle (CP) and rotationally-grazed by goats (GP) in comparison with arable land (AL). Samples were obtained by suction cup lysimeters randomly installed at three depths in an Ultisol of North Florida, USA. To evaluate nutrients in atmospheric deposition, surface and ground waters, samples from rain, nearby spring, lake and three wells on the farm were also analyzed. The results confirmed that land-use management had an effect on soil-solution N, P, K, Ca, Mg, and Na concentrations reflecting managerial and climatic conditions. The means of these nutrients ranged widely from 0.64 to 11.14 mg L -1 for N, 0.03-0.45 mg L -1 for P, 0.12-6.97 mg L -1 for K, 0.37-33.91 mg L -1 for Ca, 0.47-7.39 mg L -1 for Mg, and 1.28-4.37 mg L -1 for Na. The soil-solution N was higher from March through August (wet seasons) and lower and relatively constant between September and February (dry seasons). The N from shallow depth (0.6 m) of CP was fourfold higher than the deep (1.8 m) one and exceeded the maximum permissible level (MPL) of 10 mg L -1 . A 1.5-fold increase by depth of AL was detected, and a leaching of 53-98 kg N ha -1 was identified for both AL and CP during the wet season vs. 4-5 kg ha -1 leachable N from GP. Also, a 1-3 kg P ha -1 may be leached from CP during the wet season. The nutrients in the soil solutions tended to be higher than those in rain, lake, sprint, well, and tap waters. In groundwater however, there were episodically N concentrations as high as those in the soil solution.
