Approach to Occupational Cases of Lead Poisoning
Introduction: Lead is a toxic metal that is found in the earth's crust and has been used by humans since 7000 years ago due to its density, malleability, high resistance and low melting point. The wide use of this metal in the industry, in addition to the exposure of workers, has led to widespread environmental pollution and public health problems in many parts of the world. Due to the widespre...
متن کاملAssessment of exposure to lead through air and biological monitoring in a lead and zinc mine
Background and aim: Lead is ubiquitous and one of the earliest metals discovered by the human. This metal is widely used in different industries due to its important physico-chemical properties like softness, high malleability, ductility, low melting point and resistance to corrosion. Lead absorbed in body with several routs and when transfer in blood is primarily in red blood cells. Human exp...
متن کاملGenetic susceptibility to lead poisoning.
Major strides have been taken in the regulation of lead intoxication in the general population, but studies using genetic markers of susceptibility to environmental toxicants raise the question of whether genes can make certain individuals more vulnerable to environmental toxins such as lead. At least three polymorphic genes have been identified that potentially can influence the bioaccumulatio...
متن کاملAccumulation of zinc, cadmium, and lead in four populations of Sedum alfredii growing on lead/zinc mine spoils.
Sedum alfredii Hance is a newly reported zinc (Zn) and cadmium (Cd) hyperaccumulator native to China. In this study, four populations of S. alfredii were collected from Yejiwei (YJW), Jinchuantang (JCT) and Qiaokou (QK) lead (Pb)/Zn mines located in Hunan Province as well as Quzhou (QZ) Pb/Zn mine located in Zhejiang Province for exploring the intraspecies difference of this plant in metal accu...
متن کاملLead and Lead Poisoning from Antiquity to Modern Times
Lead, because of its low melting point, was one of the first metals used by man. It was probably isolated soon after the ancients discovered the use of fire. Archeological discoveries indicate the presence of lead objects and pigments during the early Bronze Age. In ancient Egyptian and Greco-Roman times metallic lead was produced as a by-product of silver mining. Extensive evidence of ancient ...
