To determine current secondhand smoke (SHS) concentrations in bars previously assessed as part of an evaluation of Scottish smoke-free legislation 5 years ago.
Comparison between SHS levels measured in 2006 and 2011 in 39 pubs in 2 Scottish cities.
Fine particulate matter (PM(2.5)) was measured discreetly for 30 min in each bar on one or two visits 5 years after the previous visit in May/June 2006. These 5-year follow-up visits were undertaken on the same day of the week and at approximately the same time of day.
Average PM(2.5) levels measured in a total of 51 bar visits in 2011 were 12 μg/m(3) (range 2-155 μg/m(3)) compared to 20 μg/m(3) (range 6-104 μg/m(3)) in the period immediately after the ban in 2006. Fine particulate concentrations in all but two visits in 2011 were comparable to PM(2.5) levels measured in outside ambient air on the same day, with 92% of visits (n=47) providing 30-min average PM(2.5) concentrations less than 25 μg/m(3).
These results are one of the longest follow-up of any national smoke-free legislation and indicate that, 5 years after introduction, compliance is high and that the legislation continues to provide bar workers and non-smoking customers protection from SHS.
测定 5 年前评估苏格兰无烟立法时曾评估过的酒吧中当前的二手烟（SHS）浓度。
比较 2006 年和 2011 年在苏格兰 2 个城市的 39 家酒吧中测量的 SHS 水平。
在 2006 年 5 月/ 6 月的前一次访问后的 5 年内，在每个酒吧中以 discreetly 方式测量细颗粒物（PM（2.5）），每次测量持续 30 分钟。这些 5 年随访访问是在一周中的同一天和大约相同的时间进行的。
2011 年总共进行了 51 次酒吧访问，测量到的平均 PM（2.5）水平为 12μg/m（3）（范围为 2-155μg/m（3）），而 2006 年禁烟后立即测量到的 PM（2.5）水平为 20μg/m（3）（范围为 6-104μg/m（3））。在 2011 年的所有访问中，除了两次之外，细颗粒物浓度都与同一天室外大气中的 PM（2.5）水平相当，92%的访问（n=47）提供了 30 分钟平均 PM（2.5）浓度低于 25μg/m（3）。
这些结果是对任何国家无烟立法的最长随访之一，表明在实施 5 年后，合规性很高，该立法继续为酒吧工人和非吸烟顾客提供免受 SHS 的保护。
