New York City Issues Air Quality Alert for Wednesday
NEW YORK — The Commissioner of the Department of Environmental Conservation (DEC) of the state of New York, Basil Seggos, and the Commissioner of the Department of Health (DOH), Dr. James McDonald, issued an air quality alert for the metropolitan region of New York City for Wednesday, July 26, from 11:00 a.m. to 11:00 p.m.
The reason for the alert is the high level of pollution due to ozone, which is expected to exceed an Air Quality Index (AQI) value of 100. The AQI was created as an easy way to correlate levels of different pollutants on a scale, with a higher AQI value indicating a greater health concern.
The health and air quality alert regions consist of the 5 boroughs of New York City and the counties of Rockland and Westchester.
What is ozone?
The summer heat can lead to the formation of ground-level ozone, an important component of photochemical smog. Vehicle exhaust and out-of-state emission sources are the primary sources of ground-level ozone and are the most serious air pollution problems in the northeast. This surface pollutant should not be confused with the protective ozone layer in the upper atmosphere.
Ozone is not a direct emission and is produced indirectly when sunlight chemically reacts with nitrogen oxides (NOx) and volatile organic compounds (VOCs) from vehicle exhaust and industrial emissions. High ozone is not as visible as PM2.5 because it is a colorless gas, but it will produce hazy skies and reduce visibility at high concentrations.
Who should take precautions?
People, especially young children, those who exercise outdoors, those who perform intense outdoor work, and those with respiratory illnesses (such as asthma), should consider limiting strenuous outdoor physical activity when ozone levels are higher (usually from the afternoon to the evening).
When outdoor ozone levels are elevated, going indoors will generally reduce exposure. People experiencing symptoms such as difficulty breathing, chest pain, or coughing should consider consulting their doctor.
Ozone levels generally decrease during the night and can be minimized during the day by reducing car travel and using public transportation when available.
How can we reduce pollution?
New Yorkers are also urged to take the following measures to save energy and reduce pollution:
– Use public transportation or carpool instead of driving, as car emissions account for around 60 percent of pollution in our cities.
– Conserve fuel and reduce exhaust emissions by combining necessary trips in motor vehicles.
- Turn off all lights and electrical appliances in unoccupied areas.
– Use fans to circulate air. If air conditioning is necessary, adjust thermostats to 78 degrees.
- Close blinds and curtains to limit heat buildup and preserve cool air.
- Limit the use of appliances. If necessary, operate appliances during off-peak hours (after 7:00 p.m.). These would include dishwashers, dryers, pool pumps, and water heaters.
– Set refrigerators and freezers to more efficient temperatures.
– Purchase and install energy-efficient lighting and appliances with the Energy Star label.
– Reduce or eliminate outdoor burning and try to minimize indoor sources of PM 2.5, such as smoking.
By taking these measures, New Yorkers can help improve air quality and protect their health during periods of high ozone levels.
What are the primary sources of ground-level ozone in the northeast and why is it a significant air pollution problem in this region?
The air quality alert issued for New York City on Wednesday, July 26 is due to high levels of pollution caused by ozone, according to Basil Seggos, the Commissioner of the Department of Environmental Conservation (DEC) of New York, and Dr. James McDonald, the Commissioner of the Department of Health (DOH). The alert is expected to be in effect from 11:00 a.m. to 11:00 p.m.
Ozone is a component of photochemical smog that forms at ground level, particularly during the summer heat. Vehicle exhaust and out-of-state emissions are the primary sources of ground-level ozone, making it a significant air pollution problem in the northeast. It is important to note that ground-level ozone should not be confused with the protective ozone layer found in the upper atmosphere.
Ozone is not directly emitted, but rather produced indirectly through chemical reactions between sunlight, nitrogen oxides, and volatile organic compounds from vehicle exhaust and industrial emissions. Unlike visible particulate matter (PM2.5), ozone is a colorless gas that can create hazy skies and reduce visibility at high concentrations.
The air quality alert covers the five boroughs of New York City, as well as the counties of Rockland and Westchester. It is important for individuals in these areas to take precautions to protect their health during this time.
Es alarmante ver cómo la mala calidad del aire debida al ozono está afectando a la región metropolitana de Nueva York. Es necesario que las autoridades tomen medidas urgentes para mejorar la situación y proteger la salud de los habitantes. La calidad del aire es un tema que no puede ser ignorado y requiere acciones inmediatas para garantizar un ambiente más seguro y limpio para todos.
