Thai authorities used water cannons on Monday in an effort to combat Bangkok’s air pollution. Masks were also provided after hazardous dust particles reportedly reached an Air Quality Index (AQI) of 180. Any level above 150 is considered unhealthy and Bangkok ranked in the top 10 of polluted cities worldwide on Monday. The particles, known as PM 2.5, are a mixture of liquid droplets and solid particles that can include dust, soot and smoke. Diesel fumes contributed up to 60 per cent of the pollution while burning rubbish and crops attributed about 35 per cent.
