Air Pollution - Pattaya

Recommended Posts

This was taken from the entrance to Pattaya Beer Garden around 1600 hours.  Visibility (which is affected by both particulate pollution and humidity) is as bad as I have seen it for some time.

Different types of particulate.

Yes, but one of the particulates in cigarette smoke is fine particulate matter which is what the Air Quality Index is a measure of.

Cigarette smoke produces 10 times more air pollution than diesel car exhaust

The air pollution emitted by cigarettes is 10 times greater than diesel car exhaust, suggests a controlled experiment, reported in Tobacco Control.

Environmental tobacco smoke produces fine particulate matter, which is the most dangerous element of air pollution for health. Levels indoors can far exceed those outdoors, because new engine models and lead free fuels have cut the levels of particulate matter emissions from car exhausts, say the authors.

The controlled experiment was carried out in a private garage in a small mountain town in northern Italy. The town enjoys very low levels of particulate matter air pollution

A turbo diesel 2 litre engine was started and left idling for 30 minutes in the garage, with the doors closed, after which the doors were left open for four hours. The car was fuelled with low sulphur fuel.

Three filter cigarettes were then lit up sequentially, and left smouldering for a further 30 minutes. The nicotine and tar content of each cigarette was 1 mg and 11.2 mg, respectively.

A portable analyser took readings every two minutes during the experiments.

Combined particulate levels in the first hour after the engine had been started measured 88 ug/m3. Those recorded in the first hour after the cigarettes had been lit measured 830 ug/m3: 10 times greater.

The diesel engine exhaust doubled the particulate matter levels found outdoors at its peak; the environmental tobacco smoke particulate matter reached levels 15 times those measured outdoors.

I think Gistda is working with faulty data. Pattaya has been at condition red with an AQI over 100 since 10am.

Bangkok only city with hazardous PM2.5 levels

PUBLISHED : 11 APR 2024 AT 11:20

Bangkok stood as the only city blanketed by red-coded (seriously hazardous) levels of fine dust pollution among 63 provinces battling thick smog late Thursday morning, according to the Geo-Informatics and Space Technology Development Agency (Gistda).
