The number of particles in Thailand twice the safe rate — 120 micrograms per cubic meter. Pollution Control Department, said that in most provinces after heavy rains on 11-12 March 2012 number of small suspended particles PM10 fell below levels considered dangerous. Before the rains occurred on the northern region of Thailand, for weeks the health of residents in serious danger. However, on March 15, the level of contamination was 323.4 micrograms per cubic meter, and in some regions soared to 438 micrograms. This is explained by the fact that the fires continued after the rains.
