Decline in Hospital Visits for Hospital Disorders May Be Greater Than Previously Thought
One study suggests the benefits of cleaner air may be even greater than previous data suggested.
Researchers studied the closure of a coal processing plant in 2016. Located on Neville Island, in the Ohio River, near Pittsburgh (United States), it had been used for about a hundred years to produce coke from coal for steelmaking. The closure of the plant resulted in rapid relief of air pollutants for local communities. Sulfur dioxide has decreased by 90%, arsenic by 66% and pollutant particles have also improved.
There was an immediate 42% reduction in emergency room visits for center disorders and additional decreases in the following three years, through the end of the study, demonstrating that the closure resulted in long-term innovations in health. A similar trend was observed in stroke cases. These adjustments were not observed in two communities far from the plant that were used as experimental controls.
By consulting the medical statistics, you can imagine the true delight of those involved. Testimonials from the local network reveal what it was like to live with the factory’s air pollutants, dust and odors. Other people explained that they struggled to control their asthma and others said their breathing disorders worsened when they moved to the area. It was not unusual to close windows at night when contaminants accumulated in the network.
Air pollutants are invisible in our daily lives. Reminiscent of Covid lockdowns, the factory closure brought rapid changes, and other people suddenly noticed crystal blue skies, rather than fog, and the smells of nature, as well as improved health.
Professor George Thurston, from New York University’s Grossman School of Medicine, who led the study, said: “We found that plant closure had much greater than expected benefits on the fitness of the centre. This obviously confirms that air pollutants related to fossil fuels are much more poisonous than other types of air pollutants. Policymakers have vastly underestimated the local and rapid benefits to human health that will occur as we phase out the processing and burning of fossil fuels in our towns and cities.
Professor Dan Greenbaum of the US Health Effects Institute, who was not involved in the Pittsburgh study, said: “This type of study is one of the most productive tactics to test whether exposure to air pollutants causes health problems. Simply put, if you reduce pollutants from the air a user breathes, can you measure the improvement in fitness?This is obviously the case for the citizens of Pittsburgh. “
Policies to improve air pollutants are gradual and possibly lack the ambition to bring about the big changes that have occurred near Pittsburgh. This makes it harder to find fitness benefits.
Despite this, a 17% reduction in deaths from respiratory disorders followed the ban on the sale of smoking coals in Dublin in 1990. In Aunceston, Tasmania, a program to inspire homeowners to ditch wood heating has reduced winter respiratory deaths by 28 per year. . It found that deaths in hospitals exceeded 20% and that the increase in air pollutants in Sweden favored lung growth in children.

Five of eight studies of low-emission zones (LEZs) found marked relief in circulatory and central disorders. These come with fewer hospital admissions, fewer deaths from heart attacks and strokes, and fewer people with blood pressure disorders. One of the German studies that analyzed hospital data from 69 cities with LEZ found 2-3% relief in heart disorders and 7-12% relief in strokes. These innovations have been greater for seniors and have resulted in savings in healthcare costs estimated at €4. 4. billion (£3. 8 billion).
