The South Coast AQMD has issued an air quality alert due to increased particle pollution from blowing dust. The air quality alert is in effect from Saturday afternoon to Sunday evening. In areas directly impacted by high levels of windblown dust, limit your exposure by remaining indoors with windows and doors closed and avoiding vigorous physical activity. Run your air conditioner or an air purifier. If temperatures allow, avoid using whole house fans or swamp coolers that bring in outside air. Exposure to high particle pollution levels can cause serious health problems, including asthma attacks, heart and lung disease symptoms, and increased risk of respiratory infections. People with heart or lung diseases should follow their doctor's advice for dealing with episodes of unhealthy air quality. Children, older adults, and people with respiratory or heart disease should avoid prolonged exposure and strenuous activities when particle pollution levels are high. To help minimize outdoor particle pollution levels: * Carpool, telecommute, reduce trips, or take public transportation * Slow down if driving on dirt roads * Stabilize loose soils Levels of particle pollution can vary hour by hour and by location depending on wind conditions.
