Air monitoring method based on NIOSH standard was to determine the level of lead in workplace air by means of pomp sampler. The mean level of lead at work setting was 32.1 ± ۱۱٫۲ mg/lit air and Maximum pollution level was in production unit by 34.1 ± ۱۰٫۲ mg/lit air .The airborne lead level in the forming and polishing sections was the highest and higher than the standard level. Permissible airborne lead levels by industry (3ug/m) Airborne levels to be achieved without reliance or respirator protection through a combination of engineering, work practice and other administrative controls
