NTU student creates website that estimates how many cigarettes’ worth of haze you've breathed in
"I just wanted to craft a simple-looking website, as I have a few family members and friends that are also often overwhelmed by all the different numbers, and I just wanted a simple website for them to use," Zi Heng tells 8days.sg.
NTU student Zi Heng, 21, has developed a website called "How Much Haze Have You Smoked Today?" to help people better understand the impact of Singapore's haze on their health. The website estimates the number of cigarettes' worth of fine-particle pollution one could have been exposed to based on Singapore's haze readings. Zi Heng, a Data Science and Artificial Intelligence student, was inspired to create the website after seeing family and friends overwhelmed by different haze numbers.
He wanted a simple, easy-to-use website to help people understand haze readings. Each one-hour PM2.5 reading is roughly comparable to smoking one cigarette, according to environmental research organisation Berkeley Earth. The website displays one-hour and three-hour PSI estimates alongside NEA's official 24-hour PSI readings, broken down by Singapore's north, south, east, west, and central regions.
While the website is meant to be informative and engaging, Zi Heng emphasizes that it should not be taken as medical advice or a substitute for professional health assessment.
