Bottom Line: Hair nicotine concentrations were also higher in non-smoking employees working in smoking venues (median 2.49 [0.46-6.84] ng/mg) compared to those working in non-smoking venues (median 0.16 [0.08-0.79]ng/mg).This is one of the first studies to ascertain SHS and hair nicotine in Africa.Levels were comparable to those measured in American, Asian and European countries without or before smoking bans.

ABSTRACT

Background: Secondhand tobacco smoke (SHS) exposure is a global public health problem. Ghana currently has no legislation to prevent smoking in public places. To provide data on SHS levels in hospitality venues in Ghana the authors measured (1) airborne particulate matter <2.5 μm (PM(2.5)) and nicotine concentrations and (2) hair nicotine concentrations in non-smoking employees. Quantifying SHS exposure will provide evidence needed to develop tobacco control legislation.

Method: PM(2.5) was measured for 30 min in 75 smoking and 13 non-smoking venues. Air nicotine concentrations were measured for 7 days in 8 smoking and 2 non-smoking venues. Additionally, 63 non-smoking employees provided hair samples for nicotine analysis.

Result: Compared to non-smoking venues, smoking venues had markedly elevated PM(2.5) (median 553 [IQR 259-1038] vs 16.0 [14.0-17.0]μg/m(3)) and air nicotine (1.83 [0.91-4.25] vs 0.03 [0.02-0.04]μg/m(3)) concentrations. Hair nicotine concentrations were also higher in non-smoking employees working in smoking venues (median 2.49 [0.46-6.84] ng/mg) compared to those working in non-smoking venues (median 0.16 [0.08-0.79]ng/mg). Hair nicotine concentrations correlated with self-reported hours of SHS exposure (r=0.35), indoor air PM(2.5) concentrations (r=0.47) and air nicotine concentrations (r=0.63).

Conclusion: SHS levels were unacceptably high in public places in Ghana where smoking is allowed, despite a relatively low-smoking prevalence in the country. This is one of the first studies to ascertain SHS and hair nicotine in Africa. Levels were comparable to those measured in American, Asian and European countries without or before smoking bans. Implementing a comprehensive smoke-free legislation that protects workers and customers from exposure to secondhand smoke is urgently needed in Ghana.

fig1: Real-time PM2.5 concentrations in the first five venues.

Mentions: Median (IQR, range) average PM2.5 concentrations in 75 smoking venues (smoking observed during the sampling period) were 553 (259–1038, 3–2103) μg/m3 compared to 16 (14–17, 12–30) μg/m3 in 13 non-smoking venues (smoking not observed during the sampling period). Real-time PM2.5 concentrations for the first five venues are shown in figure 1. No other visible PM2.5 source was observed. Smoking venues in Accra had higher average PM2.5 concentrations (median 688 μg/m3) compared to other cities (596 μg/m3). In smoking locations, mean (SD) active smoking density was 8.0 (5.0) burning cigarettes per 100 m3. Average PM2.5 concentrations were positively correlated (Spearman's correlation coefficient 0.55, p<0.001) with active smoking density.
