“…10 The research conducted by Maga, et al who assessed the effect of air pollution and smoking habits on exhaled air CO levels, found that in non-smokers, higher levels of exhaled CO were found in subjects living in large city areas compared to smaller cities. 11 In this study, analysis of exhaled CO levels on gender, smoking habits, and length of exposure had a significant relationship. The relationship of exhaled CO levels to gender cannot be concluded because most the majority of the subjects were women who mostly did not smoke, thus it can cause bias.…”

“…12 The research conducted by Maga, et al assessed the effect of air pollution and smoking habits on exhaled CO levels and also found that exhaled CO levels in smokers were higher than non-smokers. 11 Based on the data from the samples, CO levels in Bantar Gebang landfill is still below the quality standard threshold value. Therefore, the increase of exhaled CO levels in subjects was more due to their smoking habits and not due to length of exposure at work.…”

Results: Total sample was 108 subjects. Exhaled CO test result was 46 subjects (42.6%) had exhaled CO 5-10 ppm, 36 subjects (33.3%) > 10 ppm, and 26 subjects (24.1%) ≤ 4 ppm. Multivariate analysis between exhaled CO levels with characteristics of the subjects found smoking habits were significantly correlated with CO exhalation levels (p=0,000). Conclusion: There were 33.3% scavengers who had exhaled CO > 10 ppm. Smoking habits were the only factor that significantly correlated with CO in scavengers' exhalation.

“…In the first measurement, they were 9 times higher; in the second, 4.39 times; and in the third, 4.74 times, with significant differences between overall means of smokers and non-smokers in the winter season. This fact shows that smoking causes COHb levels to remain altered, and workers are more likely to develop grievances related to environmental pollutant exposure, in addition to specific alterations in the respiratory system caused by substances present in tobacco (MAGA et. al., 2017).…”

“…The average COex level, based on the cut-off point of 4ppm, was significantly higher among smokers than among non-smokers (p < 0.0001), and it was higher among non-smokers in large cities than non-smokers in small cities (p < 0.0001). The mean level of exhaled CO was also found to be higher in active smokers in big cities than in small cities, but without statistical significance (p = 0.14) (MAGA et. al., 2017).…”

“…The lack of significance among smokers may be due to the small number of participants, lack of control of the amount of cigarettes smoked per day, as well as the route travelled by the motorcycle taxi drivers. As the environmental quality is close to the recommended parameters, it can be assumed that levels that are already increased among motorcycle taxi drivers may have masked the interference of environmental CO in the formation of a greater amount of COHb, a factor that tends to be overcome when it comes to larger cities, with higher levels of pollution (MAGA et al, 2017).…”

Studies related to environmental pollution, carbon monoxide levels and smoking need to be deepened, especially in the case of traffic workers. Therefore, the objective was to verify the association between environmental carbon monoxide and carboxyhemoglobin levels among smoking and non-smoking motorcycle taxi drivers. A longitudinal epidemiological study was carried out with 95 motorcycle taxi drivers with measurement of the environmental carbon monoxide, carboxyhemoglobin in the exhaled air in three moments with interval of six months, between June 2014 and March 2015, as well as sociodemographic and occupational characteristics of these workers. The seasons of the year presented different carbon monoxide averages (p <0.05), with higher levels in the spring and lower in the autumn, while carboxyhemoglobin levels among smokers and non-smokers were high in the winter, fair in the spring and low in the autumn. Statistical differences were observed between subgroups: between autumn and spring for nonsmokers (p = 0.024) and between winter and autumn for smokers (p = 0.042). There was a positive correlation between carbon monoxide and carboxyhemoglobin levels for non-smokers (r s = 0.9983; p < 0.01). Environmental pollution represented different levels in the four seasons of the year and significant association with carboxyhemoglobin levels.Thecarboxyhemoglobin levels were higher among smokers, with statistical significance between winter and fall seasons, while non-smokers presented normal levels, whatconfirms the direct influence of tobacco in carboxyhemoglobin levels.
