“…These indicated also that the soil is the major source of the elements to the vegetables. Gerritse, Daniel, Smilde, and Vann (1983) asserted that high availability of a particular element in the soil can affect the relative uptake and consequently high accumulation of such element.…”

One way analysis (ANOVA) was used to analyze a large dataset of elemental levels of two vegetables -spinach (Amaranthus cruentus) and lettuce (Lactuca sativa) grown around River Jakara in Kano, Nigeria using data generated during 12 months of monitoring Ca, K, Mg, Na, (essential bulk elements) Cu, Zn, Cd, Ni, Cr, Co, Pb and Fe (trace/heavy elements) concentrations collected at three designated sites. The concentrations of the elements showed insignificant differences between sites but significant differences between some months. The soil was implicated as the major source of the elements. The concentrations of the trace/heavy metals exceeded those of the international permissible limits which pointed to the contamination of the vegetables. The mean concentrations of the elements occurred in the magnitude of Ca > Mg > K > Na > Fe > Zn > Pb > Co > Cr > Cu > Ni > Cd and Ca > Na > K >Mg > Fe > Zn > Pb > Cr > Co > Cu > Ni > Cd in the spinach and lettuce respectively. The continued consumption of these vegetables by the inhabitants of Kano and its environs present a public health risk with regards to their concentrations with heavy metals. It is therefore recommended that the relevant organ of government should find an alternative farmland for the farmers within the catchment area of River Jakara where unpolluted soil can be utilized for the production of the vegetables.

“…Soil solution concentration is considered a good predictor of metal bioavailability (Gerritse et al 1983;Kabata-Pendias and Pendias 2001). Free metal activity in the soil solution has been suggested to be the best indicator of metal bioavailability (Minnich et al 1987;Parker et al 1995), however, it is more difficult to determinate on a routine basis.…”

Background and aims The trace element uptake process of plants is a key factor in assessing the risks of trace element build-up in agricultural soils. Scarce information exists on the trace element dynamic uptake of plants grown in the field, especially on those potentially hazardous. In this study, the uptake process of As, Cd, Cu, and Zn in maize plants was quantified and characterized throughout the entire season. Methods Along two seasons, the uptake dynamics of field-grown maize plants in absorbing the soil borne trace elements was examined. Biomass production and the concentration of the elements in plant and soil solution samples were determined. A kinetic model was employed to characterize the uptake by plants. ResultsThe kinetic parameters of the uptake process, maximum cumulative uptake rate, U max , time to reach 50 % of U max , t U50 , and reciprocal of the uptake rate, b U when followed throughout the season in terms of the plant's growing degree days remained constant between seasons and were element specific. In spite of the large amount biomass produced, maize plants extracted minute quantities of Cd and As. Increasing cumulative uptake rates of As, Cd, Cu, and Zn from the soil took place primarily in the early half of the growing season when the biomass accumulation was still less than 50 % of the maximum harvested biomass. The element-specific plant uptake factor (PUF), which denote the partition of trace elements between the soil solution and plant phases, decreased following Center for the Development of Nanoscience and Nanotechnology, CEDENNA, Santiago 9170124, Chile a first-order kinetics along the growing period, did not show any significant difference between seasons, and, a t m a t u r i t y s t a g e , f o l l o w e d t h e s e q u e n c e Cd≥Zn>Cu≥As. Conclusions The uptake process of the elements was adequately described by the kinetic model, showing similar patterns but different magnitude and distribution in the plant. The extraction of Cd and As by plants is low in comparison to common inputs through fertilizer applications into maize production systems, indicating potential risk of trace element accumulation in soils. The PUF may be estimated according to the kinetics parameters of the uptake process. On a per-unit-soil solution element basis, Cd and Zn would be more susceptible to the soil-to-plant transfer than As and Cu.

“…admium is a non-essential microelement that can accumulate in seeds of edible plants at levels that exceed acceptable limits for human consumption (Gerritse et al, 1983;Hocking and McLaughlin, 2000). The daily adult human limit for Cd intake has been set at 70 μg by the World Health Organization and the U.S. Department of Health (Chaney et al, 1993).…”

The Cd concentration in the seed of crops depends on various soil factors including parent material, texture, pH, soil redox, and salinity. Cadmium accumulation also varies among crop species and cultivars within a species. Cadmium and Zn may have either an antagonistic or a synergistic effect on plant uptake that can be influenced by the soil Cd and Zn concentrations. The objective was to determine the effect of Zn fertilizer additions on the seed Cd of nine crops commonly grown in North Dakota, USA. Studies were conducted at five North Dakota locations representing different soil series during 1994 and 1995. In Experiment 1, nine crops common in North Dakota were grown with and without the addition of 25 kg ha -1 Zn fertilizer. Among crops evaluated, the greatest seed Cd accumulation occurred in flax (Linum usitatissimum L.) followed by sunflower (Helianthus annuus L.), soybean (Glycine max [L.] Merr.), and durum wheat (Triticum turgidum L. var. durum). In Experiment 2, two durum wheats and one flax cultivar were grown under three Zn treatments of 0, 5, and 25 kg ha -1 . In Experiment again flax had the higher seed Cd level compared with the two durum varieties. Based on the results from both studies, addition of Zn fertilizer did not consistently reduce seed Cd content, and even when statistically significant, the level of reduction was small and not likely to impact marketability of Cd accumulating crops such as flax, sunflower, soybean, and durum.
