Abstract

Present study assesses the uptake and allotment of heavy metals in irrigated water, soil and tomato (Lycopersicones culentum) at the export processing zone of Bangladesh. The elemental distributions of the heavy metals in the plant organs and fruits were determined after the harvesting stage. The uptake and distribution of the three heavy metals Cd, Cr and Pb were found in the several organs of tomato in reducing pattern of green tomato>plant shoot> leaf> ripen tomato> plant root; leaf> ripen tomato> plant shoot> plant root> green tomato and plant shoot> leaf> ripen tomato> plant root> green tomato while Ni has more toxic metal in Plant root but less in ripe tomato. This outline of distribution in the plant organ showed the typical pattern of a prohibited plant with a higher concentration of metals accumulated in the plant parts than in the fruits. The reducing pattern of the bio-concentration factor (BCF) showed that the ability of tomato fruits to accumulate heavy metals was reduced as the level of contamination in plant parts.

孟加拉国出口加工区周边灌溉水、土壤和番茄生产中重金属的积累

本研究评估了孟加拉国出口加工区灌溉水、土壤和番茄(Lycopersicones culentum)对重金属的吸收和分配。测定了采后植物器官和果实中重金属元素的分布。绿番茄>植株枝条>叶片>成熟番茄>植株根系对Cd、Cr、Pb三种重金属的吸收和分布呈减少模式;叶片>成熟番茄>植株芽>植株根>绿番茄和植株芽>叶片>成熟番茄>植株根>绿番茄。这一植物器官的分布轮廓显示了典型的违禁植物，其金属在植物部分的积累浓度高于果实。生物富集因子(BCF)的降低规律表明，番茄果实对重金属的积累能力随着植株各部位污染程度的增加而降低。

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
