Last week, residents of New York and Philadelphia found themselves dealing with high levels of smog. The usually bustling cities were shrouded in a haze of pollution, causing concern among both residents and environmentalists. The sudden appearance of smog raises questions about its origins, the potential health risks it poses, and the necessary measures to prevent its recurrence. Read on below to learn about some of the factors behind the recent smog in New York and Philadelphia.
Smoke from wildfires in Canada
Last week’s thick smog in New York and Philadelphia was caused primarily by smoke coming south from the wildfires that have been going on in Canada. The wildfires are reportedly burning faster than in most years, and strong winds from the north were continually pushing the fire and the smoke further south into the northeastern United States.
While wildfires have been the primary source of smog news recently, smog was a problem in the region even before these wildfires began. The problem in New York, Philadelphia, and some other major cities isn’t just due to the fires — there are other factors as well. Some of these factors include:
Industrial emissions and traffic congestion
One of the primary culprits behind the smog in New York and Philadelphia is the emission of pollutants from industrial activities and vehicular traffic. Both cities have large industrial sectors and a high volume of vehicles, leading to significant emissions of various pollutants. These pollutants, when combined with sunlight and heat, undergo complex chemical reactions in the atmosphere, which results in the formation of smog.
Weather conditions and temperature inversions
Weather conditions often play a crucial role in exacerbating the smog problem. One common problem is temperature inversions — a meteorological event where a layer of warm air traps pollutants close to the surface, preventing their dispersion. The stagnant air caused by temperature inversions allowed smog-forming pollutants to accumulate, leading to the visible haze that blanketed the cities.
The geography of the Northeastern United States also contributed to the smog issue. Both New York and Philadelphia are located in regions with high population densities and are surrounded by other major urban centers. The combined emissions from these densely populated areas can lead to the formation of regional-scale smog, which can be transported over long distances by winds like the ones we saw last week.
Health impacts and environmental concerns
The presence of smog raises significant health concerns for the residents of New York and Philadelphia and the surrounding areas. Exposure to air pollution such as smog can lead to respiratory problems, aggravate existing respiratory conditions, and increase the risk of heart disease and lung cancer. Children, elderly people, and people with pre-existing health conditions are particularly vulnerable.
The environmental impacts of smog also can’t be overlooked, as it contributes to the degradation of air quality, harms ecosystems, and damages crops and vegetation. This decreased air quality affects not only humans but animals and even plants as well.
