Air quality in Bangkok dropped further on Friday morning (Feb 16) with PM2.5 fine particulate matter measured at between 52-62 microgrames per cubic metre, exceeding the limit of 50 microgrammes/ cu m.
Burning of joss paper and incense sticks during the Chinese New Year today partly caused the PM2.5 level in the capital to rise, according to the Pullution Control Department (PCD).
PCD director-general Sunee Piyapanpong said PM2.5 level measured at 8 am at six air quality monitoring stations on Rama IV road, Intharapithak road, Lat Phrao road, Phaya Thai road, Bang Na and Wang Thong Lang districts exceeded the standard 50 microgramme per cu m.
Ms Sunee said the level of the health-threatening fine particulate matter in the capital was expected to drop today due to rising temperature, but it turned out that the level rose possible due to the burning of joss paper and incense stick during the Chinese New Year celebrations.
Bangkok Metropolitan Administration deputy permanent-secretary Suwanna Jungrungrueng also warned that burning of joss paper could also emit toxic substances from gold and silver colours coated on the paper.
Ministry of Natural Resources and Environment's permanent secretary Wijarn Simachaya asked worshipers in Bangkok and surrounding provinces to burn joss paper only in small amount to help reduce air pollution.
The burning should also conduct in confined space to prevent the dust from spreading further.
