بررسی تماس شغلی با پارا فنیلن دی آمین ( PPD ) موجود در هوای استنشاقی آرایشگران زنانه شهر ساری و عوامل محیطی تاثیر گذار

Background and aims: Hairdressing because of using hair dyes, are exposed to PPD that endanger their health. Measuring the concentration of PPD is a sure way to evaluate the PPD facing rate. PPD causes leukemia and other blood disorders. PPD acute poisoning leads to respiratory distress, rhabdomyolysis, muscle necrosis and renal failure, severe edema of the face and neck, increased serum lactate deshydrogenase, creatine phosphokinase. The aim of this study is to evaluate occupational &nbsp;woman hair dressers PPD and it&rsquo;s affecting factors in Sari. Methods: In this cross-sectional study which was conducted in September 2016, samples were taken from 47 barber in Health Centre number 3. To measure the PPD, a three-piece cassettes sampler was used, and the samples were analyzed by HPLC) High performance liquid chromatography(. The Kata thermometer was used to measure PPD&rsquo;s affecting factors such as air flow rate and the&nbsp; thermo-hydrometer&nbsp; was used to air temperature, and humidity. For data analysis methods based on regression analysis, independent test and chi-square test and Fisher were used. The significance level was considered as P<0.05. Results: PPD average concentration of samples was 1.89%&plusmn; 0.00093. The PPD concentration was significantly associated with hairdresser&rsquo;s ambient humidity (P<0.001, r =0.36). The relationship between work space and concentrations of PPD was significant (P<0.001, r =0.32). Association between PPD&rsquo;s concentration and the number of operators was statistically significant (P<0.022, r =0.24). The relationship between the concentration of PPD with drying temperature, flow rate, ventilation, and local exhaust ventilation was not significant.
