a total number of 67 workers of teheran battery workshops were investigated for probable lead absorption due to the working with lead storage batteries. twenty workers with other occupations were selected as control group. blood and urine analysis were carried out for both groups. lead content of the urine in about 95.5% of the subjects was below 10 μg/100 ml. two subjects showed higher concent...
background: hematological effects and digestive and neuro-psychological signs and symptoms are some manifestations of lead toxicity. however, there are conflicting reports of their prevalence among lead exposed workers and their relationship with blood lead levels (bll). this case- control study assessed the relationship between bll and hematological indexes and digestive (abdominal colic, iron...

The aim of this study was to evaluate the role of alloying and rapid solidification processing in direct structural control in lead base batteries. A detailed investigation on rapid quenching of liquid lead base alloys for high performance storage battery applications was made in order to choose suitable lead grid alloys for lead acid batteries as melt-spun ribbons. So this paper provides a com...
background: the interaction between serum neuron-specific enolase (nse), biogenic amino-acids and neurobehavioral function with blood lead levels in workers exposed to lead form lead-acid battery manufacturing process was not studied. objective: to evaluate serum nse and biogenic amino-acids (dopamine and serotonin) levels, and neurobehavioral performance among workers exposed to lead from lead...
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...

T he use of lead in the electronics industry today accounts for approximately 7% of total lead consumption.' The single largest use of lead is in the manufacture of storage batteries, which accounts for 60% of the total lead produced.2 The use of lead is closely regulated in plumbing, paint and gasoline industries. Currently, the electronics industry has been exempted from the existing requirem...
