An air quality alert is in effect today from 2 p.m. to 10 p.m. EDT.
The forecast air quality index for ground-level ozone today on Long Island is 115, which is unhealthy for sensitive groups, including very young children, the elderly and people with pre-existing respiratory problems such as asthma or heart disease.
The New York State health department recommends that people in the posted areas consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects.
The federal environmental protection agency warns that elevated ground-level ozone can cause:
irritation of the airway, coughing and pain when taking a deep breath;
wheezing and breathing difficulties during exercise or outdoor activities;inflammation, which is much like a sunburn on the skin;
aggravation of asthma and increased susceptibility to respiratory illnesses like pneumonia and bronchitis; and
permanent lung damage with repeated exposures.
Ground level ozone is produced by by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight, according to EPA.gov. Emissions from industrial facilities and electric utilities, motor vehicle exhaust, gasoline vapors, and chemical solvents are some of the major sources of NOx and VOC.
Health officials advise limiting outdoor activities during the period of the alert.
The state has established a toll-free air quality hotline: 1-800-535-1345.
