This study was aimed at assessing the effects of spent engine oil on
hematological parameters, renal and liver status of auto-mechanics. A questionnaire was
design and blood sample was collected from both auto-mechanics and non-mechanics. The
response from the questionnaire indicated complaints of pains around thoracic region, skin
rashes etc; unawareness of the detrimental contents of spent engine oil; poor precautionary
and sanitary practices. Assessment of renal status indicated that plasma urea and creatinine
levels for auto-mechanics (18mg/dl and 0.81mg/dl, respectively) were significantly higher
compared to non-mechanics (16mg/dl and 0.68mg/dl, respectively). Haematological profile of
the auto-mechanics compared to non-automechanics showed that packed cell volume
increased significantly (41%) for auto-mechanics compared to non-automechanics (39%);
haemoglobin concentration increased significantly (14.3g/dl compared to 13g/dl); and
neutrophils increased significantly (34% compared to 26%). Though, lymphocytes increased
(65.9%) compared (65.5%, for non-automechanics), this was not significant (p=0.850).
Neutrophils (p<0.05) and lymphocytes (p=0.850) increased for the automechanics (33.5% and
65.9%, respectively) compared to the non-automechanics (26.4% and 65.5%, respectively).
Alkaline phosphatase activity increased (19.7U/l) compared to (16.6U/l, non-automechanics);
while aspartate transaminase and alanine transaminase significantly decreased (13.4U/l and
7.4U/l, respectively) compared to (9.7U/l and 4.8U/l, respectively). Thus, the uses of hygienic
protective practices are encouraged like the use of face and nose mask, and auto-mechanics
are encouraged to go for regular medical check-up.
