Bangkok fires water cannon into the air to fight pollution

An excerpt from Bangkok Post(14 Jan 2019 )

The capital fired water cannon into the hot tropical air and hosed down streets on Monday as authorities handed out masks in a bid to combat air pollution in one of the world’s most visited cities which has been blanketed by smog since Saturday.

The Agriculture Ministry was also preparing to seed clouds to try to clear the air.

The level of hazardous dust particles known as PM 2.5 has exceeded the safe level in 30 of 50 Bangkok’s districts for days, Bangkok governor Aswin Kwanmuang told reporters.

PM 2.5 is a mixture of liquid droplets and solid particles that can include dust, soot and smoke. It is one of the main pollutants included in measuring the Air Quality Index (AQI).

Monday morning’s AQI in Bangkok was 180, according to the popular website airvisual.com, which measures levels in cities worldwide. The temperature was a sizzling 31 degrees Celsius.

Any level above 150 is considered unhealthy and Bangkok ranked in the top 10 of polluted cities worldwide on Monday. At the top was Tel Aviv in Israel, at 454 on the index.

Pollution in Bangkok has reached unhealthy levels before, usually during the dry season between January and March, but it doesn’t normally hang around too long.

Authorities vowed to keep fighting.

“The city will hand out N95 masks that can protect people against PM 2.5 dust… We will distribute the first 10,000 masks to people in various spots around the city,” Pol Gen Aswin said earlier in the day.

Many shops have ran out of masks because of high demand.

“We have been sold out since Saturday,” Supannee Boriwongse, 37, a drug store manager in Silom area, told Reuters.

“We have ordered more but were told that there is a shortage.”

The Department of Pollution Control says diesel fumes from cars contribute 50-60% of the pollution while burning rubbish and crops attributed about 35%.

The government has banned large trucks from entering downtown Bangkok during the rush hours, while police have vowed to enforce the law on emission controls.

Breaking news on NYE air pollution

From: Airtoday.ph, a public service of Rotary Club of Makati air monitoring team

January 1, 2019

Real-Time NYE air pollution levels at an all-time low but lingered longer

For the fourth straight year, the public service website www.airtoday.ph of the Rotary Club of Makati provided real-time air pollution warning on the levels of inhalable and respirable air due to the effects of fireworks in Metro Manila. The website is measuring both PM10 and PM2.5 in two locations this NYE: Ayala Avenue in Makati City and Lung Center of the Philippines (LCP) in Quezon City, both adjacent to designated community fireworks display sites (Ayala triangle and Quezon Memorial Circle, respectively).

As soon as the clock strikes midnight, both stations recorded “Very Poor” air pollution; with Ayala Avenue Makati Station recorded the highest PM concentration around 1:00 am January 1, 2019 with 114 micrograms per cubic meter of air (ug/m3) for PM10 and 113 ug/m3 for PM2.5, which was well above WHO’s 25 ug/m3 safe standard, but significantly lower (about 24% and 14%) compared to last years’ readings of 149 ug/m3 for PM10 and 131 ug/m3 for PM2.5 for the same station.

Warnings at Ayala Avenue, Makati station (Figure 1) recorded “Poor” air quality between December 31, 2018, 7:00 to 9:00 pm, and 11:00 pm, and then again from January 1, 2019, 4:00 am to 6:00 am.” Very Poor” air quality were recorded right after midnight from January 1, 2019, 12:00 am to 3:00 am.

Around the same time, the LCP station recorded a PM concentration of 99 ug/m3 for PM10 and 98 ug/m3 for PM2.5. Warnings at LCP (Figure 2) recorded “Poor” air quality from December 31, 2018, 5:00 pm to 7:00 pm, and 11:00 pm, and then again from January 1, 2019, 2:00 to 3:00 am. “Very Poor” air quality were recorded from December 31, 2018, 8:00 to 10:00 pm, and then again from January 1, 2019, 12:00 to 1:00 am.

PM concentrations at both stations were well above WHO safe standard but significantly decreased at around 4:00 am (January 1, 2019), albeit at the Ayala Avenue, Makati Station still maintaining a “Poor” air quality reading (same as last years’) which change to “Moderate” at around 7 am.

Air particulate matter (PM) are tiny dust that can be inhaled or respired, depending on the size of the pollutant. According to Dr. Mylene G. Cayetano, faculty at the Institute of Environmental Science and Meteorology, UP Diliman and technical expert of www.airtoday.ph, Tropical Depression Usman affected this NYE’s air quality in both positive and negative ways. The rain clouds brought about by Tropical Depression Usman washes away the particles emitted by fireworks and firecrackers. These same rain clouds (combined with colder temperature) prevents polluted air from dissipating farther upward, hence, trapping the particulates from the fireworks on the ground for more extended periods to be ingested into the respiratory system of people in Metro Manila.

Air PM levels for both airtoday.ph stations started to increase as early as 4:00-5:00 pm on December 31, 2018; with air quality index ranging from “Moderate” to “Very Poor”, earlier than previous 2 years which started at 11:00 pm for December 31, 2016 and 8:00 pm for December 31, 2017.

The www.airtoday.ph is a public service initiative by the Rotary Club of Makati since 2016. It aims to synergize actions from the stakeholders, both government and non-government, on mitigating the impacts of air pollution.
