“…Chen et al (2009) andZhang et al (2011) used a Gaussian distribution function to match the Cd PUF variations for vegetables cultivated in California and vegetable data extracted from the literature. In general, the reported PUF values and distribution patterns (Chen et al, 2009;Zhang et al, 2011;Swartjes et al, 2013) were comparable to that of the PUFs calculated in the present study.…”

“…In doing so, other environmental factors such as SOM, irrigation condition, and fertilizer usage, which related to the accumulation of Cd in vegetables are often overlooked (McBride, 2002(McBride, , 2014Hough et al, 2004). A large number of national environmental agencies recommend investigating the environmental factors related to the plant Cd uptake (Swartjes et al, 2013;Augustsson et al, 2015), but detailed studies are few.…”

“…The consumption of vegetables is a probable cause of Cd exposure in several world areas including China (Hough et al, 2004;Xu et al, 2013;Norton et al, 2015). In some countries like southern Sweden and Uganda, the consumption of vegetables may contribute from 70% to 80% of the total Cd intake by humans (Nabulo et al, 2010;Swartjes et al, 2013). Low-level concentrations of Cd in vegetables can also lead to kidney and liver dysfunction (Thomas et al, 2009).…”

“…), and fertilizer usage (Chaney et al, 1978;Kuboi et al, 1986;Nabulo et al, 2012;Zhao et al, 2015). A large uncertainty appears when use PUF to describe the accumulation of Cd in vegetables in relation to a large range of environmental factors (Chen et al, 2009;Swartjes et al, 2013). Several studies focusing on the relation between Cd concentrations in vegetables and total Cd soil concentrations or soil pH, use empirical regression methods.…”

“…Risk assessment of heavy metal accumulation in wastewater irrigated leafy vegetables, such as palak (Beta vulgaris L.), amaranthus (Amaranthus caudatus L.), and cabbage (Brassica oleracea L.) was reported by Anita et al 6 Intake of metalcontaminated vegetables is a pathway for heavy metal toxicity to humans. 13,14 Intawongse and Dean 15 determined the bioavailability of Cd, Cu, Zn and Mn in the human gastrointestinal tract from the edible part of the vegetables by using an in-vitro gastrointestinal extraction technique. They found that the edible portions of 'lettuce and radish' are more responsible than other vegetables for heavy metal accumulation in humans.…”

HOW TO CITE:Alaribe FO, Agamuthu P. Fertigation of Brassica rapa L. using treated landfill leachate as a nutrient recycling option. S Afr J Sci. 2016;112(3/4), Art. #2015-0051, 8 pages. http://dx.doi.org/10.17159/ sajs.2016/20150051 Optimising nutrient availability and minimising plant metal contamination are vital in sustainable agriculture. This paper reports experiments in which treated leachate was used at different concentrations with predetermined N content for fertigation of Brassica rapa L. (leafy vegetable). An inorganic fertiliser, with N content equivalent to the leachate amount, was also prepared, as well as a control. Growth (leaf length, leaf width and stem height), harvest parameters (total number of leaves, root length and root dry weight) and specific growth rates (mm/day) were determined for three consecutive seasons. The dry weights of leaves, roots and stems in the leachate treatments were within the ranges of 1.95-3.60 g, 1.18-3.60 g and 0.33-1.37 g, with biomasses of 1.75 g, 1.14 g and 0.2 g, respectively, which were higher than those of the control. B. rapa L. fertigated with 25% diluted treated leachate recorded high specific growth rate and a leaf length of 0.53 mm/day and 0.23.17±0.58 cm, respectively (%N=0.023; p<0.05). The maximum permissible mineral concentration set by the Food and Agricultural Organization of the United Nations/World Health Organization (FAO/WHO) was compared with that of the grown plants. Treated leachate can increase plant nutrient content.

Metal contamination of urban soils and homegrown vegetables has caused major concern. Some studies showed that cadmium (Cd) was among the most significant hazards in kitchen garden soils and prolonged exposure to this metal could cause deleterious health effects in humans. In general, most risk assessment procedures are based on total concentrations of metals in vegetables. The present study assesses human bioaccessibility of Cd in vegetables cultivated in smelter-impacted kitchen garden soils. Seven vegetables (radish, lettuce, French bean, carrot, leek, tomato, and potato) were considered. Using the UBM protocol (unified BARGE bioaccessibility method), the bioaccessibility of Cd was measured in raw/cooked vegetables. A considerable amount of Cd was mobilized from raw vegetables during the digestion process (on average 85% in the gastric phase and 69% in the gastrointestinal phase), which could be attributed to a high uptake of Cd during the growth of the vegetables. Most Cd is accumulated in the vacuoles of plant cells, except what is absorbed by the cell wall, allowing Cd to be released from plant tissues under moderate conditions. Cooking by the steaming process generally increased the bioaccessibility of Cd in French bean, carrot, and leek. For potato, few or no significant differences of Cd bioaccessibility were observed after the steaming process, while the frying process strongly decreased bioaccessibility in both phases. The estimation of metal bioaccessibility in vegetables is helpful for human health risk assessment.
