Dietary intake of many heavy metals through consumption of plants has long term detrimental effects on human health. This detrimental effect varies with the nature of an element as well as plant species. pp. 4 ii. Chemical fractionation of an arsenic-contaminated soil spiked with 50 or 200 mg kg À1 Ni, Zn, Cd or Pb was performed before and after growing the Introduction. Background: A pot experiment was conducted to determine the toxic effects of some heavy metals on the plant growth and seed yield of maize (Zea mays L.). Cultivation of crops on contaminated sites may result in both growth inhibition and tissue accumulation of heavy metals with resulting possible risks to humans health. Toxic levels of metals in soils may be caused by natural soil properties or by agricultural, manufacturing, mining and waste disposal practices. There have been a large number of studies regarding the tolerance, uptake and defense mechanism in several of these species, notably Brassica juncea and B. napus, against the stress induced by heavy metals.

These HM ions enter in soil biota from various sources like natural and anthropogenic. This study examined the effects of heavy metals and plant arsenic uptake on soil arsenic distribution. Phytotoxicity results in chlorosis, weak plant growth and yield depression, and may even be accompanied by reduced nutrient uptake, and disorders in plant metabolism (Dan et al., 2008). Metals are unique environmental and industrial pollutants in the sense that they are neither created nor destroyed by human beings but are only transported and transformed into various products. Metal accumulating plant species can concentrate heavy metals like Cd, Zn, Co, Mn, Ni, and Pb up to 100 or 1000 times those taken up by nonaccumulator (excluder) plants. A pot study was conducted to investigate the toxiceffects of certain heavy metals on the plant growth and grainyield of wheat (Triticum aestivum L.). BIOACCUMULATION OF HEAVY METALS Pollutants like heavy metals are CONSERVATIVE pollutants – i.e. 1: Effects of trace metals on plant function. Malik Ghulam Asghar Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. Heavy metal toxicity means excess of required concentration or it is unwanted which were found naturally on the earth, and become concentrated as a result of human caused activities. Development of metal tolerance is a major way to reduce the harmful effects of excessive exposure to heavy metal ions (Tyler et al., 1989). View Heavy metals Research Papers on Academia.edu for free.
