“…The observation of significantly elevated levels of ALT and AST in exposed individuals in this study is in line with the findings of Akintonwa and Oladele [10] , Nwanjo and Ojiako [12] , Saadat and Ansari-Lari [27] , and Michailova et al [28] .…”

“…In 1998, Michailova et al [28] reported significant increases in the serum activity of ALT and AST in oil industry workers. Similar results were reported in 2003 by Akintonwa and Oladele [10] in workers of pump stations. Likewise, in 2004, Saadat and Ansari-Lari, in a study on 56 workers of Shiraz pump stations, reported significantly elevated plasma levels of creatinine, and serum activity of ALT and AST, as well as significantly decreased albumin and protein values in the exposed group as compared to a control group.…”

“…For instance, kidney adenoma [5] , elevated serum activity of liver enzymes [6] , [7] , urea, creatinine, and potassium, and decreased chlorine and sodium have been reported in laboratory animals [8] . Similarly, proteinuria, elevated serum activity of liver enzymes (aspartate aminotransferase, alkaline phosphatase, alanine aminotransferase), and total bilirubin and fatty liver changes have been reported in drivers and workers following exposure to unleaded petrol [9] , [10] , [11] , [12] .…”

BackgroundUnleaded petrol contains significant amounts of monocyclic aromatic hydrocarbons such as benzene, toluene, and xylenes (BTX). Toxic responses following occupational exposure to unleaded petrol have been evaluated only in limited studies. The main purpose of this study was to ascertain whether (or not) exposure to unleaded petrol, under normal working conditions, is associated with any hepatotoxic or nephrotoxic response.MethodsThis was a cross-sectional study in which 200 employees of Shiraz petrol stations with current exposure to unleaded petrol, as well as 200 unexposed employees, were investigated. Atmospheric concentrations of BTX were measured using standard methods. Additionally, urine and fasting blood samples were taken from individuals for urinalysis and routine biochemical tests of kidney and liver function.ResultsThe geometric means of airborne concentrations of BTX were found to be 0.8 mg m−3, 1.4 mg m−3, and 2.8 mg m−3, respectively. Additionally, means of direct bilirubin, alanine aminotransferase, aspartate aminotransferase, blood urea and plasma creatinine were significantly higher in exposed individuals than in unexposed employees. Conversely, serum albumin, total protein, and serum concentrations of calcium and sodium were significantly lower in petrol station workers than in their unexposed counterparts.ConclusionThe average exposure of petrol station workers to BTX did not exceed the current threshold limit values (TLVs) for these chemicals. However, evidence of subtle, subclinical and prepathologic early liver and kidney dysfunction was evident in exposed individuals.

“…Findings of this research agrees with outcome of previous study done by Azeez et al (2015). Also Akintonwa et al (2003) showed that there was significant elevation in both systolic and diastolic blood pressure, about 12.5% of the petrol attendants had systolic blood pressure varying from 141-160mmHg while 28.6% had diastolic blood pressure ranging from 91-110mmHg. Data from this study also corroborates previous study (Azeez et al, 2012) that documented the pressor effect of petroleum hydrocarbon.…”

Petrol pump attendants are group of workers that are daily exposed to petrol fumes across petrol filling stations in major cities within Nigeria and sub-Sahara Africa. The objective of this study is to evaluate the effect of petrol fumes on changes in some cardiovascular parameters among petrol pump attendants in Ughelli, Delta State Nigeria by measuring arterial blood pressure and calculating pulse and mean arterial pressure of 150 petrol attendants with age, sex matched control within Ughelli metropolis and its environs. Data obtained show that the arterial blood pressure, pulse and mean arterial pressure ranged from 108/60-140/92, 48-80 and 76-126 mmHg respectively. The result also revealed that mean arterial pressure significantly (p<0.05) increase in the petrol pump attendant. More so, the systolic and diastolic blood pressure increased in a duration of exposure dependent manner with significance (p<0.05) in petrol pump attendants working for more than five years. The mean arterial pressure was significantly (p<0.05) increased in subjects working as petrol pump attendants for less than five years and five years or more. Data also showed that the pulse pressure was not adversely affected in the petrol pump attendants. In conclusion, this study has established that there are changes in cardiovascular parameters of petrol pump attendants as shown with an increase in systolic, diastolic and mean arterial pressure.
