Heavy metals found in urban air with its toxic effects have a direct impact on human health. Selection of appropriate tree species and shrub refining capacity of heavy metals in urban areas can greatly reduce the toxic effects of these materials. This study aimed to identify the most suitable tree and shrub species of broadleaf evergreen, deciduous and coniferous refinement of heavy metals lead...

Background & Aims of the Study:  Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Method...

Water is one of the most important compounds for existence nature and human life. Nowadays, as a result increasing industrialization industrial production, heavy metals pollute clean water resources. Copper (II) ions are leading in industry. There high proportion copper especially production printed electrical electronic circuit, paper silicon synthesis, wood preservation, fertilizer oil refini...

The study of a well-preserved crucible fragment from the Middle Kingdom Egyptian fortress in Buhen lower Nubia revealed unexpected presence numerous prills very arsenic- and nickel-rich copper alloy what looks like smelting slag. Based on optical scanning electron microscopy polished section, this paper discusses potential metallurgical process that was carried out type crucible. Strongly reduc...
