Indonesia has made some belated arrests over the burnings this year. Smoke from farms on Sumatra and Kalimantan disturbs the country's neighbors of Singapore and Malaysia every year. This is the first time, however, that an unhealthy level has been recorded on Phuket in Thailand.
In comparison with today's level of PSI 125 on Phuket, the island-nation of Singapore was recording levels between 163-181, according to live readings taken soon after 10am.
An atmospheric inversion is being blamed by meteorologists for the haze on Phuket. Its presence became noticeable yesterday and was clearly considered harmful with today's 6am measurement of PSI 125.
On previous days, the Phuket pollution measurement showed nil on Tuesday, PSI 21 on Wednesday, PSI 17 on Thursday and PSI 24 on Friday.
