Exposure to hazardous pollutants may have an immediate or a long-term effect, which may not show up for many years. The significance of the exposure depends upon the source, how much is emitted from the source, how harmful the pollutants are, and how much of the pollutants have accumulated within the home. Some immediate symptoms of exposure may include headache, dizziness, fatigue and upper airway irritation of the nose, throat and eyes. These symptoms may reoccur with repeated exposures.
