This study was conducted to evaluate the influence of occupational noise (sound stress) exposure on

fasting serum lipid and lipoprotein levels [ serum total cholesterol (TC) ,Triglycerides(TGs) and lipoproteins

profile : Very Low Density Lipoprotein(VLDL),Low Density Lipoprotein(LDL-C) and High Density

Lipoprotein (HDL-C)] in Erbil textile factory workers .These workers are exposed to high ambient noise

level which is generated by big machines used in the factory for more than six hours daily at a strength of 90

deci-Bel [dB] without using ear protectors . The date obtained indicate that under these conditions of

chronic and high noise exposure levels there are a significant increase (P< 0.05) in the level of fasting serum

(TC) , a non significant increase in the levels of fasting serum ( TGs ,VLDL and LDL-C) and a significant

decrease (p< 0.05) in the level of fasting serum (HDL-C) .
