Abstract

Benzene is classified as a Group I carcinogen by the International Agency for Research on Cancer IARC The risk assessment for benzene can be performed by monitoring environmental and occupational air as well as biological monitoring through biomarkers The present work developed and validated methods for benzene analysis by GC/MS using SPME as the sampling technique for ambient air and breath The results of the analysis of air in parks and avenues demonstrated a significant difference with average values of 405 and 1826 μg m−3 respectively for benzene Sampling of air in the occupational environment furnished an average of 341 and 3981 μg m−3 Moreover the correlations between ambient air and expired air showed a significant tendency to linearity R 2 = 0850 and R 2 = 0879 The results obtained for two groups of employees 3191 and 7262 μg m−3 presented the same trend as that from the analysis of environmental air
