Smog Alerts Coming

Summer will soon be here and that can mean high levels of air pollutants in our air, specifically ozone and small particles, commonly known as smog.

Meteorologists declare “Air Quality Action” days when they project that weather conditions are conducive for unhealthy air pollution. In 2016, the Pennsylvania Department of Environmental Protection (DEP) called six action days for the Susquehanna Valley.

We should heed those warnings. Recent scientific studies conclude that short-term exposure to unhealthy air pollution can have significant adverse effects on pregnant women, children, the elderly, and even the general population–especially those with pre-existing conditions such as asthma. Short term symptoms resulting from breathing high levels of ozone and fine particulate are chest pain, coughing, nausea, throat irritation, and congestion. These pollutants also aggravate bronchitis, heart disease, emphysema, and asthma—and can increase risks of stroke. Children, senior citizens, and those with asthma or other respiratory problems are urged to limit outdoor activities when an action day is predicted.

Air Quality Action days are often declared when there is little wind and when the amount of ozone or particles in stagnant air could exceed federal health standards. The DEP monitors local and regional air quality. Local television and radio stations alert the public when an Air Quality Action day is predicted. Check your newspaper’s websites as well. The Clean Air Board of Central Pennsylvania also monitors pollution levels and posts notices at this website when DEP declares an Air Quality Action day.  Stay informed!

EPA’s ozone health standard – what it means for us

On October 1, the Environmental Protection Agency changed its  National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb), based on extensive scientific evidence about ozone’s effects on public health and welfare. The new standards are intended improve public health protection, particularly for at-risk groups including children, older adults, people of all ages who have lung diseases such as asthma.

The Clean Air Board actively participated in the EPA rule setting process, providing comments and testimony.  Learn how the new standard will be implemented in central Pennsylvania, and what we should do next.

 Join us at our community meeting at Second Presbyterian Church, 528 Garland Drive, Carlisle, PA, Nov. 5, 7 pm.

AIR QUALITY ACTION DAY HAS BEEN DECLARED FOR SUSQUEHANNA VALLEY ON FRIDAY, JAN 23

 The Department of Environmental Protection has declared an air quality action day for Jan.23.
Tomorrow’s Forecast
Friday, Jan 23: 110 AQI Unhealthy for Sensitive Groups Particle Pollution (2.5 microns)

Extended Forecast
Saturday, Jan 24: 81 AQI Moderate Particle Pollution (2.5 microns)
Current conditions: Clouds and fog are breaking up across the region as of 1 p.m. EST this Thursday afternoon. High pressure will slowly build into the area overnight tonight into Friday. We are concerned about very light winds near the surface as the high builds in with very little mixing expected. In addition, temperature inversions are likely to trap PM2.5 close to the ground. So for tonight, expect some clearing skies with very light winds. Fine particulate will increase into the code ORANGE range later on tonight as the temperature inversion develops. Low temperatures close to 20 degrees. Friday’s forecast: A PM2.5 Action Day will be declared for the day Friday as very light winds and some warming aloft will bring any mixing in the boundary layer to a halt. Code ORANGE concentrations of fine particulate are likely with this scenario. With some sunshine, afternoon temperatures will recover into the middle 30s. A storm system coming out of the deep South will then move northeastward towards us Friday night into Saturday, and with the current forecast track, we could be in line for a quick inch or so of snow during this period. Precipitation could briefly turn to a bit of rain by later Saturday morning as temperatures creep just above the freezing mark. While atmospheric mixing will be a little greater on Saturday, fine particulate concentrations will remain well into the moderate range. *** Extended forecast: The weather pattern will continue to be an active one as we move into the early part of next week. A clipper system will move eastward and affect the area later Sunday night into Monday with snow. Because the low is expected to track more to the south, precipitation could fall as all snow as cold air remains in place. Following this, a large area of high pressure builds in for Tuesday into Wednesday of next week with dry weather and light winds. Low moderate levels of PM will occur Sunday into Monday, but with high pressure building in next week with existing snow cover, we have to again be concerned with stronger inversions trapping fine particulates close to the ground.–McAuliffe

NY Times article: Air Pollution Linked to Heart and Brain Risks

Air Pollution Linked to Heart and Brain Risks

By ANAHAD O’CONNOR

It may be time to start paying more attention to those local air pollution alerts.

That is the message of three new studies this week that found, collectively, that people exposed to higher levels of air pollution have a greater risk of stroke, heart attacks and cognitive deterioration.
