Background: Occupational lead poisoning is common in workers of some industries, but lead hepatotoxicity has rarely been reported. Several animal studies have revealed lead induced liver damage but clinical studies concerning the manifestations of lead induced liver toxicity in humans are scares. This study was designed to investigate the clinical manifestations and pathological parameters of h...
Background and Aim: Iron deficiency anemia is the most common nutritional anemia in developed and developing countries. In addition, lead intoxication especially in developing countries is an increasing risk for health because of rapid urbanization and consumption of leaded fuels. Many studies, particularly on children, have showed a correlation between iron deficiency and increase in blood lea...
Introduction:Lead and zinc are among the most poisonous unnecessary heavy metals available in the environment and are among the first grade poisonous pollutants. In this study the efficiency of electrocoagulation process using alternating and direct current and iron and stainless steel rods for elimination of lead and zinc from battery industrial wastewater has been investigated. Methods:Wa...
Lead acid batteries are one of the most commonly used batteries. Monitoring the performance parameters of the battery provides essential data useful for managing the batteries efficiently. This paper proposes a highly accurate and efficient battery monitoring system based on NI LabVIEW. As the calculations are done on computer, this system is faster than micro-controller based systems and provi...
This paper presents an effective technique to monitor and predict the open circuit voltage (OCV) for lead-acid battery cells. The underlying principal of the technique described in this paper employs one simple equation to predict the equilibrated cell voltage after a small rest period. The technique was tested and analyzed using results obtained from experiments conducted at the Yuasa Battery ...
Lead acid batteries have been widely used in different fields, so abundant waste lead battery was generated. Waste is regarded as a toxic material due to the metallic and paste compounds. Once its compounds enter human body environment, which will cause serious threats. At present, are mainly recovered form of metal lead, has many problems. Thus, this paper put forward novel technology recycle ...
