Characterization for types and percents of polycyclic aromatic hydrocarbons in sera of workers at fuels stations at Baghdad

الملخص EN

Allpolycyclic aromatic hydrocarbons (PAHs) have a hightoxicity, and/or carcinogenic and or mutagenic to most microorganisms andhumans.

Main aim to this study is to providecontemporary information (quantitative and qualitative) PAHs in sera of fuel stations, workers whom exposure with petroleum products.

The study includes 60 male petrol-filling workers in 5 petrol stations around Baghdad.

Their ages were between (20 – 50) years.

For compared the results a 30 sera samples from healthy individuals was collected with corresponding age-matched as control group.

The samples were collected from October 2017 until April 2018.

The BMI was calculated for all subjects.

Technique of High performance liquid chromatography (HPLC) was used to detect the presence of PAHs quantitatively and qualitatively in the sera of all subjects.

The mean level of total PAHs in sera of workers was 1275.65± 934.267 higher than that for healthy subjects 67.380 ± 46.16 with significant value p=0.033.

Also the types and percent of PAHs in the sera of workers were differ.

For studying the epidemiologic, no correlation between the percent of % PAHs in sera of workers who exposure to petroleum withoutaffected withtheir age and BMI.
