This article reviews the presence of heavy metals in different vegetables, their mechanism of absorption, impact of heavy metals on physiology, and nutrient reduction and associated impact on humans with emphasis on pregnant women based on the existing scientific literature. 2. A heavy metal is toxic when relatively it is dense metal or metalloid that is noted for its potential toxicity, especially in environmental contexts. 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). /ProcSet [/PDF /Text ] Springer Netherlands, Sep 1, 1981 - Science - 258 pages.

Introduction. Bahauddin Zakariya University Multan Pakistan. 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. They reduces productivity, bring stunting in growth and loss in chlorophyll (chlorosis) and protein contents in higher aquatic plants These metals are incorporated permanently in plants and then are passed on to animals and human beings. The main purpose of this book is to present comprehensive and concise information on recent advances in the field of metal transport and how genetic diversity affects heavy metal transport in plants. The impact of the heavy metals on aquatic organisms is due to the movements of pollutants from various diffuse or point sources which gives rise to … Heavy metals are among the most important sorts of contaminant in the environment. 2) R. Mayer. To minimize the detrimental effects of heavy metal exposure and their accumulation, plants have evolved detoxification mechanisms. View Heavy metals Research Papers on Academia.edu for free. Plants possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. /Resources << /F1 6 0 R From the two studied plants C. chinensis expressed typical symptoms of the heavy metal toxicity including the decrease of total chlorophyll, chlorophylls a, b. Toxic levels of metals in soils may be caused by natural soil properties or by agricultural, manufacturing, mining and waste disposal practices. Our measurements showed that both growth and photosynthetic pigments are affected by the presence of heavy metals. Heavy metals (HMs) exists in the environment in both forms as essential and non-essential. /Font << 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. 56-66. /F4 15 0 R HEAVY METALS are natural components of the Earth's crust they cannot be degraded or destroyed to a small extent they enter our bodies via food, drinking water and air as trace elements, some heavy metals (e.g. Among these heavy metals, a few have direct or indirect impact on the human body. Heavy metals are persistent in nature, therefore get accumulated in soils and plants. Exposure to heavy metals by the consumption of contaminated vegetables and its toxicity is a serious concern. In Vietnam, accumulation of heavy metals in soil, water and plant biomass has been widely reported. This definition is not acceptable and also inconsistent in use as already stressed in literature. /F5 18 0 R In addition, plants accumulate metal ions that disturb cellular ionic homeostasis. The term “heavy metal” was defined mainly by the specific weight of metals. Several species from the Brassica genus are very important agricultural crops in different parts of the world and are also known to be heavy metal accumulators. Editors: Lepp, N. W.
