“…2), and the roots contained about twice as much Ni as did tops. Similar results have been reported by others (Checkai et al, 1986;Dang et al, 1990). Cataldo et al (1978) reported that Ni had the highest concentrations in root tissue followed by leaves = stem > pod = seed.…”

“…At the same levels of soil applied Ni and N, the reductions in the dry matter yield of wheat roots were 95, 86 and 82%, respectively. Similar yield reductions with Nitrogen and nickel interactions 215 the application of Ni have been observed (Dang et al, 1990;Khalid and Tinsley, 1980;Wallace et al, 1977), which may be attributed to factors like stiffening the expansion zone tissue, destruction of the integrity of roots meristems (Robertson, 1985), reduced chlorophyll and increased levels of protochlorophyll (Anderson et al, 1979), imbalance in nutrition of other essential nutrients (Cataldo et al, 1978), or a combination of such effects.…”

A glasshouse experiment was conducted to study the effect of Ni on the growth and nutrients concentration in wheat (Triticum aestivum Cv. WH 291) in the presence and absence of applied N as urea. Responses to N application were observed up to 120/~g N g-~ soil. No response to Ni was observed in the dry matter yield of wheat tops (leaves + stem) in the absence of applied N while in the presence of applied N, significant yield increases were obtained at 12.5/~g Ni g-~ soil. Nickel was not toxic to wheat up to 50/.~g Ni g-i soil in the presence of 120/~g N g-I soil. Nitrogen and Ni concentration in wheat tops and roots increased with increasing levels of applied N and Ni, respectively. Applied Ni had an antagonistic effect on N concentration. Similarly, N reduced the Ni concentration in the wheat tissues. Positive growth responses to Ni were associated with 22 and 15/~g Ni g-~ in wheat tops, in the presence of applied N at 60 and 120p~g N g-~ soil, while Ni toxicity was associated with 63, 92.5 and 112.5/~g Ni g-t in wheat tops, in the absence and presence of applied N at 60 and 120~g N g-~ soil, respectively.

“…Lettuce is used for toxicity assessment in moderate pH environment (pH 6-8) (ISO 2005b;Sheppard et al 1993;Chapman et al 2010Chapman et al , 2012 because it is not a good acid-tolerant species (Chapman et al 2012;Environment Canada 2005). Among higher plants, oat is recommended for toxicity tests of heavy metals (Chang et al 1997;ISO 2005a) under low pH conditions (Loureiro et al 2006;Small and Jackson 1949;Bilski and Foy 1987), while Allium cepa is Pb tolerant in acidic environment (Dang et al 1990). Heavy metal tolerance capability of plants may be associated with their chemical form (Yang and He 1995).…”

Heavy metal contamination is a globally recognized environmental issue, threatening human life very seriously. Increasing population and high demand for food resulted in release of various contaminants into environment that finally contaminate the food chain. Edible plants are the major source of diet, and their contamination with toxic metals may result in catastrophic health hazards. Heavy metals affect the human health directly and/or indirectly; one of the indirect effects is the change in plant nutritional values. Previously, a number of review papers have been published on different aspects of heavy metal contamination. However, no related information is available about the effects of heavy metals on the nutritional status of food plants. This review paper is focused upon heavy metal sources, accumulation, transfer, health risk, and effects on protein, amino acids, carbohydrates, fats, and vitamins in plants. The literature about heavy metals in food plants shows that both leafy and nonleafy vegetables are good accumulators of heavy metals. In nonleafy vegetables, the bioaccumulation pattern was leaf > root ≈ stem > tuber. Heavy metals have strong influence on nutritional values; therefore, plants grown on metal-contaminated soil were nutrient deficient and consumption of such vegetables may lead to nutritional deficiency in the population particularly living in developing countries which are already facing the malnutrition problems.

“…Studying Fabia beans, Metwally and Rabie (1989) observed no effect at 50 mg Ni kg-I in alluvial or sandy soils. Dang et al (1990) studied the effect of Ni and other metals on the growth of fenugreek and onion; adding 50 mg Ni kg-I to a clay loam caused a significant 20% reduction in the yield of both onion and fenugreek, with a total failure at 400 mg Ni kg-I. Halsted et al (1969) studied the toxic effects of Ni in alfalfa and found no effects at 20 mg but did note effects at 50 mg Ni kg-I.…”
