Dust is still the main problem.
It is reproted to exceed the standard level at all stations monitored. Other air pollutants recorded such as carbon monoxide and lead are still under the standard level in all monitoring stations. It is, however, reported that the quality of air in other provinces has not become a serious problem except in some areas like Saraburi Province where dust from rock extraction is a major problem. The noise level is considered to be dangerous for people living in BMA, especially those living in close proximity to transportation routes during traffic congestion, in the business and offices zone. The noise level along the canals is very high, particularly when boats are passing and at rush hour.
