MEASUREMENT OF THE CONCENTRATION OF LEAD IN GASOLINE STATIONS AND IN AIR BATTERY FACTORIES AND THEIR EFFECT OF CYTOGENTIC AND HAEMATOLOGICAL PARAMETERS IN WORKERSFaisal Hadi Ghani Qawaizi AL-Amier Hind Suhail Abdulhay and Salah Mahdi Mohsen
This study was attempted to find the effects on some possible genetic and Haematological parameters of the lead in product in the battery factories and for the workers in the continuously exposed fuel stations for the tetraethyl lead. Samples divided in two group workers (75) adultsâ men and control 10 adultsâ men. The study has been conducted in Baghdad City from March 2017 to April 2018. The results showed that mean lead levels in battery factories workers were 28.50 Â± 0.52 ïg/dL and less in fuel station workers 21.79 Â± 0.66 ïg/dL. The mean blood lead levels in the control group were 8.70 Â± 1.09 ïg/dL. The results showed a significant difference between the mean blood lead levels and the study samples (workers and control). Results showed that the effect of lead was clear on the examination of the complete blood pictures of the workers compared to the group of control. Occupational exposure to lead to leads to increased frequency of genetic system in human beings in the present study the DNA damage among the workers occupationally exposed to lead was analyzed using peripheral blood lymphocyte by comet assay. Samples of fuel were obtained from fuel stations (Al-Mansur, Al-Waziriya, Al-atifiyah and Al-Kadhimiya) stations where the results showed significant differences between the above stations. The highest mean concentration of lead in fuel at Al-Mansour station was 20.53 Â± 0.69 ïg/dl, which were less than 14.63 Â± 0.82 ïg/dl, at Al-Waziriya stations. AL-Kadhimiya station 11.53 Â± 1.76 ïg/dl below the Al-atifiyah stations 1.41Â±0.08 ïg/dl. Air samples were taken during the study period. The results showed that the mean lead levels in the air inside the battery factories at many levels allowed 50 ïg/cmÂ³ according to Occupational Safety and Health Administration where the mean concentration of lead in the workplace was 179.75 Â± 28.63 ïg /mÂ³ compared to the permissible limits of 50. 00 Â± 0.10 ïg/mÂ³ the study also showed significant differences between the concentration of lead in the air and the permissible limit.
