 Environmental
Tobacco Smoke
CEE has completed two projects for the Minnesota Partnership for
Action Against Tobacco regarding environmental tobacco smoke.
The second project was a collaboration with the Minnesota Institute
for Public Health to test the air quality in 25 hospitality venues
before and after implementation of smoke-free ordinances in Hennepin,
Ramsey, and Dakota Counties. The project was extended to include
monitoring in Beltrami County. The concentration of respirable particulates
due to environmental tobacco smoke showed a 99% decrease in communities
that implemented a complete ban on smoking in bars and restaurants
and levels of ultrafine particulate pollution decreased by 87%.
CEE was also the host organization for the Minnesota Partnership
for Action Against Tobacco project Clean Indoor Air in Apartments – Researching
Effective Strategies. This project included in-depth owner interviews,
a survey of a large sample of renters, legal research and measurements
of the movement of PFTs and SHS tracers between units in apartment
buildings before and after air sealing and ventilation treatments.
The project produced some of the most extensive multiple fan measurements
of inter-apartment air leakage and multiple tracer gas measurements
of inter-apartment air transfer. It also developed a new metric of “effective
contaminant transfer” which is used to define the magnitude
of the transfer of a contaminant source to the monitored location.
