Amount of environmental lead pollution is increased with progression of industry. This pollution is able to damage the living beings in many ways. Blood and Immune systems are more sensitive to toxic effects of lead. 30 female and 6 male rats from Sprague dawley race are chosen by simple random sampling. After copulation and vaginal plug observation, expectant rats are calssified in test and co...

Introduction The accumulation of capital is being considered as a major driving force as far as the development is concerned. The mechanism of this accumulation implemented during three processes. Capital accumulation within different historical and geographical setting results in special locational forms known as space economy. Historical experiences with respect to capital accumulation in ...

OBJECTIVES Lead (Pb) pollution is a serious public health problem all over the world, it especially plays severe damage role in children's health. Apart from reducing lead-induced damages, the decrease of lead accumulation is also critical. This study has been the first attempt to investigate effects of meso-2,3-dimercaptosuccinic acid (DMSA), potassium iodide (KI) and chlorophyll (Chl) on lead...

Providing healthy food and protecting sources from pollution has been one of the concerns of human societies and decision – making centers so that protecting food from pollution, detecting sources of pollution and measuring them become important. Because of nutritive and political significance of grape in this area, extensive use of leaf and fruit of this plant, developing urban areas around gr...

Influence of lysine and zinc administration on lead-sensitive biochemical parameters and the accumulation of lead during exposure to lead were investigated in rats. The lead exposure inhibited blood δ-aminolevulinic acid dehydrogenase (δ-ALAD) activity, increased blood zinc protoporphyrin (ZPP), urinary δ-aminolevulinic acid (δ-ALA), serum glutamic oxaloacetate transaminase (AST), serum pyruvic...

The effect of lead application on nutrient and Pb content and accumulation in ipê-roxo (Tabebuia impetiginosa (Mart.) Standl.) seedlings was studied in an experiment conducted under greenhouse conditions at the Soil Science Department of the Federal University of Lavras. The seedlings were cultivated in Clark nutrient solution and submitted to increasing Pb levels: 0, 48, 96, 192 and 288 μmol/l...
