the pollution of soil by heavy metals is considered to be quite a big problem in many areas ofthe world. to limit the accumulation of lead and cadmium from soil in the products, a correct understanding ofthe characteristics and specifications of the translocation of cadmium and lead is necessary. in order to evaluatethe effects of cadmium and lead interaction on zinc and manganese concentration...

abstract background and purpose:the rapid urbanization and industrialization in many parts of the world have led to the accumulation of heavy metals in the terrestrial environment and pose a serious threat to human health. in this study, a broad assessment was conducted to estimate the levels of heavy metals in groundwater in sistan and baluchestan via geographic information system (gis), iran,...

background and objectives: heavy metals such as cadmium and lead are the most important toxins spreading through various ways like water, soil, and air in nature and easily enter human food chain. it is essential to determine the cumulative and harmful effects of these metals in nutrients, especially in cow milk because it is a unique source of food for all ages and it contains both essential a...

abstract nowadays, soil pollution with heavy metals has become a major problem which their accumulation in plants can directly or indirectly influence on animals and humans life. lead and cadmium are poisonous metals, with increasing the amount of these metals in environmental pollution; they will be increased in food chain significantly. in this research, three levels of cadmium (0, 100 and 20...

in this paper, leaching of lead and cadmium was investigated from porcelain over glaze designs between different colors.  also the effect of microwave heating was considered on leaching of lead and cadmium.  dishes were selected with a decor with the dominant color of gray, red, yellow, blue, and dark blue. amounts of cadmium and lead which leached from the container by acetic acid and orange j...

background: presence of heavy metals in leachate due to the biological accumulation characteristics of these materials endangered the living creatures' health especially human. purpose of this study is to study and investigate the possibility of two metals' absorption i.e, lead and cadmium from leachate by natural zeolite clinopteliolit and increase of the ability to absorb the zeolite by modif...

in this study, the effectiveness of kiwi shell was investigated to reduce the mobility of lead and cadmium in clay soil in different intervals. for this purpose a clay soil sample was contaminated with lead and cadmium in distinct dishes with 10 and 600 ppm concentrations respectively and mixed with 5% kiwi shell. samples were placed in incubator, and then sampling of soil in incubator was perf...
