The effects can be most dangerous for children, the elderly and people with asthma. Ozone can aggravate asthma , causing more asthma attacks, increased use of medication, more medical treatment, and more visits to hospital emergency rooms. Ozone can present an increased risk to the elderly because it can aggravate pre-existing respiratory diseases and is associated with increased hospital admissions. Every day air quality data is collected from a network of air monitoring stations located in Allen County. When data from these monitors indicate conditions are right for unhealthful levels of ozone, the public will be advised to take precautions, and asked to avoid ozone-generating activities until the health threat has passed.
Conditions are right for ozone formation on hot, sunny days with little wind.
Precautions you should take include avoiding physical exertion whenever air pollution levels are high. This is especially important for children, the elderly, and people with lung and heart diseases. When possible, limit all outdoor activities or stay indoors when air pollution levels are high. Take the bus or ride a bicycle. Work at home if possible.
