today, biosphere pollution has accelerated strongly with start of industrial revolution by toxicity of heavy metals. one of existing pollution is soil pollution. unfortunately, soil pollution by metals is as intensive environmental stress for plant hence for human. plants, which are able to store heavy metals in their organs, can be used for phytoremediation of polluted soils and utilization of...

We are frequently asked, what does hair analysis reveal about heavy metals? First, heavy metals are so ubiquitous in our environment that everyone is exposed to them. They cannot be avoided completely and are found in virtually everyone to some degree. Most clinician’s are aware that hair tissue mineral analysis (HTMA) measures nutritional minerals and the heavy metals that are incorporated int...

Heavy metal intoxication is a consequence of the accumulation metals in body. The toxicity heavy metals, particularly lead, arsenic, cadmium and mercury, remains significant problem challenge for future investigations.

Due to insufficient clean water resources wastewater is largely used for irrigation of vegetables in many developing countries, particularly in Pakistan. As a result, vegetables in spite of providing nutrients also accumulate toxic metals and causes health risks. In the present study, comparison of heavy metal contents, using two digestion methods, in fresh and wastewater-irrigated vegetables w...

alfalfa and maize are important agricultural plants for animal consumption. in this survey, accumulation quantity of heavy metals (fe,zn,mn,cd,pb,ni,cr) in plants irrigated by sewage and well water were compared statistically together and with normal or standard(permeable) limits in plants or foraging, during 2005. the results were as following 1-maize: the value of accumulation in maize irriga...

Microalgae Sorption of Ten Individual Heavy Metals and their Effects on Growth and Lipid Accumulation

This study assesses the ability of mycelia of Rhizopus delemar (both free and immobilized on polyurethane foam) to remove heavy metals from single-ion solutions as well as from a mixture of them. All experiments were conducted using 0.5-5 mm solutions of CuSO4 x 5H2O, CoCl2-6H2O and FeSO4 7H2O. Mycelia immobilized on polyurethane foam cells showed some times increase in uptake compared with tha...
