Smoke-developed index (SDI) from cigarette in Thailand’s airports is
four times higher than in the United States, according to a research
conducted by Mahidol University.
If no measures are taken, people with heart disease or asthma could experience heart failure, said the survey.
The research was conducted in four main airports, including
Suvarnabhumi, Don Mueang, Phuket, and Chiang Mai. It showed that
passengers are being exposed to a high intensity of cigarette smoke, 773
micrograms per cubic meter, which is much higher than the limit
Thailand has defined at 50 micrograms per 1 cubic meter.
The World Health Organisation (WHO) also limits the SDI at only 25
micrograms a cubic meter. The survey also suggested that 58 percent of
the smokers at these airports are foreigners.-VNA
