Abstract

This descriptive study was done on 45 printing and copying centers during 2011 to 2012. In order to measure the intensity of electromagnetic fields and UVA intensity, the HI-3603 and 3604 VLF and ELF survey meter and a radiometer (Hanger ECI-UV-A) were used, respectively. For sampling BTEX compounds in the air, using OSHA and NIOSH guidelines, activated carbon tubes manufactured by SKC was used. Air in taking was performed by a personnel pump (SKC, 224-44EX). According to NIOSH method and SKC sorbent instructions, the sampling time of 8 hours and air flow passing of ml/min200 was chosen. After sampling, two-end of the glass tube adsorbent was completely closed by a plastic cap and they were maintained at a temperature of zero degrees Celsius prior to extraction and analysis. After extracting, the samples were measured using a gas chromatography (Varian CP-3800) equipped with a FID detector. Data were managed using SPSS version 16 and the Relation between electromagnetic field intensity values ??and measuring distances (30, 50 and 60cm) was analyzed by Pearson statistic test.
