Situation is dramatic right now regarding air pollution because severe smog. Officials from Thailand’s Pollution Department estimate that vehicle emissions account for roughly 60 percent of the city’s chemical haze. Earlier this month, Bangkok cracked the list of the top 10 cities with the foulest air on the planet. In Bangkok, particulate matter from vehicle emissions is at an all time high and routinely exceeds the national safety standard, which is 50 μg/m3 annually and 120 μg/m3 within a 24-hour period. In the past two weeks, schools across Bangkok have had to close due to toxic smog.
The government has even deployed drones to spray water and damp down the pollution. They also considered some outlandish ideas, like using giant fans to blow the pollution out of town. It’s not just breathing problems that plague those in areas with high air pollution: symptoms can range from chest pain, headaches, nausea and increased sensitivity to allergens to aggravated heart disease, reproductive / neurological disorders and even cancer. The World Bank estimated that air pollution related deaths in Thailand have risen nearly 20,000 in the past 20 years.
