background: heavy metals contaminations are recognized as the serious risk to our environment. the aim of the present study was to analyze heavy metals residue in cultivated mango samples from iran. methods: totally, 72 mango samples were randomly collected among six different mango genotypes cultivated in southern iran from june to july 2015. lead, chromium, cadmium, and arsenic were determine...

introduction: nowadays, advancements in industries, technology and human welfare level have lead to accumulation of solid wastes and have endangered environmental health. incorrect waste management intensifies this problem. recycling and composting (transformation of organic waste to humus) are the most important ways in waste management. health and safety of the compost is an important issue b...

There is an increasing concern about heavy metal contamination in farmland in China and worldwide. In order to reveal the spatial features of heavy metals in the soil-rice system, soil and rice samples were collected from Nanxun, Southeastern China. Compared with the guideline values, elevated concentrations of heavy metals in soils were observed, while heavy metals in rice still remained at a ...

The contamination from heavy metals has been rising from the last decade due to increase in industrialization. The heavy metals are toxic for living organisms. The accumulation of heavy metals may lead to severe health problems. Many drugs are known to remove heavy metals from living organisms but sometime they may be destructive. The need-of-the-hour; however is to evolve procedures for remova...

The transfection assay is an important tool for evaluating the health effects of industrial chemicals, with the reporter gene expression as an indicator. However, heavy metals often influence the expression of the reference plasmids used to correct variations in transfection efficiency between assay plates, reducing the reliability of this assay. We found that the target of heavy metals is the ...

To prepare measures for practical policy utilization and the control of heavy metals, hazard control related institutions by country, present states of control by country, and present states of control by heavy metals were examined. Hazard control cases by heavy metals in various countries were compared and analyzed. In certain countries (e.g., the U.S., the U.K., and Japan), hazardous substanc...

introductionenvironmental pollution, especially marine pollution, is one of the complex and minatory problems that human is facing at the present time. many of human activities have irrecoverable outcomes and affect the marine environment in such a way that destruction of marine zones has become a significant warning. one of the most important ecosystems in iran is hara biosphere reserve, locat...

Heavy metals are normally occurring elements that have a density at least 5 times higher than of water. Their plentiful domestic, industrial, agricultural and technological usages have led to their widespread distribution in the environment; raising worries over their possible impacts on human health and the environment. The toxicity of heavy metals relies on numerous factors including the dose...
