Wind brought some relief and hazardous dust levels dropped in greater Bangkok on Friday, but the air remained unhealthy in some areas including along the capital's Rama IV Road. The Pollution Control Department said 10-30 kilometres per hour wind in the morning reduced hazardous dust particulate levels. In these area PM2.5 levels were measured at 54-74 microgrammes per cubic metre of air. The Health Department warned parents to keep young children indoors and close doors and windows to screen oot dust. The department said exposure to excessive particulate matter could cause chronic health problems for the young, including cardiovascular disease, and adversely affect their nervous system and intelligence levels.
