Abstract
This study was conducted during the period from December 2012 to May 2013, the study included measuring the concentration of heavy metals (Pb, Hg, Cd) in serum of workers in the coal and study its effect on a number of biochemical parameters for (38) male subjects with a control group including (50) persons who were living away from areas of pollution and non-workers in the industrial sector (and non smokers at the same age groups). The trase elements were measured by using flameless atomic absorption spectrophotometer. Results showed a significant difference (p <0.01) for each of lead, mercury and cadmium, which were 0.0296ppm, 0.0485ppm and 0.1825ppm, respectively, compared to the control group, which were 0.0035ppm, 0.0055ppm and 0.0070ppm respectively, there were a significant changes (p <0.01) in urea, creatinine, total protein , enzyme phosphatase and transaminase enzymes (ALT, AST), Their levels were 35.8mg/dl, 1.398mg/dl, 59.22g/l, 96.90U/I, 32.65U/I and 55.97U/I respectively, compared to the control group, which were 24.71mg/dl, 0.929mg/dl, 66.34g/l, 67.10U/I, 20.43U/I and 22.88U/I respectively.
