Bacteriological and chemical study on the effect of lead in blood and saliva of workers in batteries industry factory in Baghdad

الملخص EN

objectives : .

The study aims at:1- measuing the level of lead in workers' saliva and blood in the factory.2- studying the correlation between the saliva lead level and the infection that caused by microorganisms, isolation and dication.

3-studying the influence of high blood lead level on the total white blood cells.

,methodology : This study has been conducted for the period from March 15th, 2010 to May, 20th, 2010.

A total of (60) & blood samples were collected from workers in batteries industry factory in Baghdad and another (20) samples [ected as a control group.

Lead level had been measured in blood and saliva samples, then microorganisms were he from the saliva samples.

Microbial growth was submitted from morphological and biochemical investigation fication of bacterial and fungi.

On the other hand; the total white blood cells and differential count were measured.

The results showed that the streptococcus mutans isolates were dominated species which are isolated from the nples with 35% and 22.5% of Candida albicans.

On the other hand, the lead level had been measured in blood and nples, the results showed that the occupation years affect on accumulation of the lead in the blood and saliva and it differences were found at (p<0.01) in samples from worker at 15 occupation years.

Additionally, the results of 'revealed statistically non-significant in total white blood cells count comparison with controlling group.

endations: The study recommends conducting laboratories tests for workers in factories that deal directly or with lead and establishing health education seminars to demonstrate the dangers of lead how we deal with it.
