Assessment Changes in Hematological Parameters for Iraqi Individuals That are Working in Petrol Refineries
Keywords:hematological disorders, petrol pump operators, volatile chemical contaminants
The attention has been increased to assess the hematological toxic effects of petroleum products from
refineries especially the volatile chemical contaminants (VCC) like benzene. Petrol pump operators
are workers frequently exposed to petroleum products that has been occasionally associated with large
incidences of hematological disorders and adverse health effects as a result of damage to the haemopoietic
system accompanied by depletion to the bone marrow. This study was made to evaluate the hematological
parameters among petrol refinery workers according to the duration of exposure. A cross sectional study
was done in Al Najaf -refinery for petrol. It involved 101 petrol pump operators, thirty one (31) healthy
male office workers who were considered as the control group and two groups of seventy (70) male petrol
pump operators as the study group. The samples of blood were collected from both study and control groups
and tested for red blood cells count (RBC), hemoglobin concentration (Hb), white blood cell count (WBC),
packed cell volume (PCV) level and platelet count (Plt). Chronic exposure to volatile chemical contaminants
has a harmful effects on refinery workers with increasing the risk of developing hematological disorders due
to the deleterious effects on the bone marrow
