OBJECTIVE: To analyse buccal epithelial cells for scoring the frequency of cytogenetic toxicity in petrol pump workers. METHODS: The case-control study was conducted at the Lahore College for Women University, Lahore, Pakistan, from September 2014 to February 2015, and comprised petrol pump workers. Buccal micronucleus cytome assay was carried out by the collection of buccal cells after the written and oral consent of petrol pump workers. Frequencies of genotoxic (micronucleated and binucleated) and cytotoxic (karryorhetic and karyolitic) cells were scored and compared with the control group. The control group samples were collected randomly by keeping in view that these workers had not worked in petrol pumps ever. SPSS 16 was used for data analysis. RESULTS: Of the 200 participants, there were 100(50%) workers and 100(50%) controls. Statistically significant results were observed on the comparison of frequencies of different cell anomalies in subjects compared to controls on the basis of job duration, smoking habits and age (p< 0.05 each). CONCLUSIONS: Pump workers showed higher frequencies of cytogenetic toxicity compared to controls.
