BANGKOK, Oct 2 (TNA) – Scattered rains help reduce the
levels of fine dust particles PM 2.5 in Bangkok that have soared over safe
limit for many days.
The Pollution Control Department (PCD) reported the level of
PM2.5, particulate matters smaller than 2.5 micrograms, dropped from 40-81
micrograms per cubic meter on Monday to 19-52 micrograms on Wednesday.
Bang Kho Laem was the only district hit by high
concentration of PM2.5 exceeding safety threshold of 50 micrograms per cubic
meter, according to the PCD.
The overall Air Quality Index for Bangkok has improved
thanks to rainfalls in many parts of the capital city Tuesday night, the
Department says.
Ultra-fine dust particles exceeded safe threshold in most
parts of Bangkok on many days since last week, prompting the government to
introduce measures to combat the pollutants.
Officials have blamed the micro pollutant to car fumes and
high pressure system which has lowered temperatures.
Some other provinces such as Khon Kaen and Ang Thong have
also been hit with unhealthy levels of PM2.5.
Khon Kaen registered 101 micrograms of PM2.5 per cubic meter Wednesday
morning, due to the high pressure system blocking air circulation.
High concentrations of PM2.5 were detected in Ang Thong
province as burning of farm waste continue despite official warning.
