UNLABELLED OBJECTIVE. The present study was carried out to investigate the effects of occupational lead exposure on the hematological and biochemical parameters in occupationally exposed and non exposed inhabitants of Karachi. MATERIAL AND METHODS. In 100 lead exposed subjects recruited from automobile workshops, lead battery repair and recycling units located in Karachi and in 100 control subj...

Ž . The environmental impact of both the vanadium redox battery vanadium battery and the lead-acid battery for use in stationary applications has been evaluated using a life cycle assessment approach. In this study, the calculated environmental impact was lower for the vanadium battery than for the lead-acid one. The net energy storage efficiency of the vanadium battery was greater due to lower...

The lead battery has the potential t o become one o f the first examples o f a hazardous product managed in an environmentally acceptable fashion. The tools o f industrial ecology are helpful in identifying the key criteria that an ideal lead-battery recycling system must meet: maximal recovery of batteries after use, minimal export of used batteries t o countries where environmental controls a...

Background: The battery recycling and manufacturing involves the use of metallic lead for making grids, bearing and solder. The process results in release of lead particles and lead oxide causing environmental pollution and severe lead poisoning. Aims and Objectives: To know the present scenario of the blood lead level and its biochemical effects on occupational lead-exposed population, mainly ...

A study of the kinetic analysis of total lead from spent Car battery ash by hydrochloric acidleaching has been examined. The physico-chemical analysis of the ash powder was carried outby the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and X–ray diffraction (XRD).The effects of the acid concentration, temperature and particle size on the rate of battery ashdissolution have been investi...
