Abstract
The objective of this study was to evaluate effect of noise and gases rising from electrical power generators on physiological blood parameters , liver functions in of workers in electrical generators in Al - Najaf Al-Ashraf city. The noise levels and gaseous pollutants emissions from electrical power generators were measured in Najaf city center. In each quartier, several generators were chosen to measure various noise and gaseous pollutants parameters at different time intervals. Additionally, the study also included determines blood parameters and liver functions in 30 electrical generators workers selected from two sectors and 30 unexposed subjects as control group. The results indicated that estimated average noise level (LAeq) from the electrical generator in Al-Ansar quarter was 95.350±0.750 dB(A) and Al-Shorta quarter was 93.35±1.35 from the electrical generator during morning and evening periods in south sector in Al-Najaf city. The study noted in this study is that all the quarters visited in southern sector during morning period have decibel levels above the recommended limits set by WHO. Furthermore, The results recorded that there was elevation in carbon monoxide (Co ) concentration emitted by electrical generators in south sectors compared with permissible limits of gaseous air pollutants emission from electrical power generators in Iraq. In addition, the results showed that there was a significant elevation (P≥0.01) in total white blood cells of electrical generators workers comparison with control group. Also, the study elucidated that significant increment (P≥0.01) in serum aspartate aminotransferase (AST) in workers of electrical generators comparison with control.
