A “corrected” century-old formula has made the universal tracking of atmospheric air pollution more accurate.
The atmosphere’s altered composition is the primary driver of climate change.
Beyond warming the planet, many airborne nanoparticles and pollutants also impact public health.
Unfortunately, an oversimplified mathematical equation has made their monitoring unreliable, affecting medicine and climate science.
Will fixing this analytical gap help accurately predict how differently shaped toxins travel in the air?
How the planet’s air rapidly shifted
Long before the Industrial Revolution and modern technology, Earth looked significantly different.
The atmosphere had a stable baseline that the planet could maintain.
Carbon dioxide levels were consistent for thousands of years.
Other greenhouse gas levels were nearly equally low and balanced by natural carbon sinks.
But over the last two centuries, the atmosphere’s composition has dramatically changed.
The global population increased rapidly, leading to widespread industrialization and great consequences.
The air breathed by mankind changed.
Manufacturing, urbanization, and the burning of fossil fuels released dense synthetic particulate mixtures into the sky.
The movement of these tiny particles interested the scientific world.
Ebenezer Cunningham created a mathematical formula in 1910 to predict this particulate behavior.
It determines how air resistance slows down small, drifting substances.
However, Cunningham’s calculation was flawed. It assumed all particles had the same spherical shape.
Yet, scientists used this flawed formula for over a century.
The complications of using a simplified formula
Scientists chose to use this spherical assumption to simplify their calculations.
At the time, technology was not advanced enough to account for the infinite variations of real-world shapes.
Without the required computing power, this “convenient flaw” allowed basic math to work.
However, using this shortcut created a dangerous blind spot for medicine, public health, and the renewable energy sector.
Experts were unable to monitor the spread of nanotoxins and pollutants.
This meant that technologies designed to absorb pollution may not have been as effective as thought.
Furthermore, the air quality in major cities could be significantly lower, affecting human health.
This is because inhaled toxins like viruses, microplastics, and jagged soot do not float like smooth spheres.
Additionally, climate models may have miscalculated how much heat is trapped in the atmosphere. Global temperatures could be rising more quickly than believed.
Fortunately, an aerosol science research team solved the problem.
Identifying the true shape of pollution particles
Professor Duncan Lockerby from the University of Warwick led the breakthrough.
The team’s findings can be reviewed in the study “Scientists finally solve a 100-year-old mystery in the air we breathe,” published by the University of Warwick via Science Daily.
The 1910 Cunningham correction factor was updated by introducing a tool called a correction tensor.
It acts as a flexible multiplier within Cunningham’s original formula.
Calculations are easily adapted based on the drag and resistance of any physical shape.
Discerning among the wide, irregular variety of shapes
Air pollutants do not have a single “true” geometry.
Microplastics, dust, and volcanic ash can be sharp shards, fragments, or thin discs.
Soot and combustion emissions are highly jagged, branched, or assembled clusters.
Viruses and airborne pathogens are usually multifaceted or asymmetrical.
Real-world pollution is fundamentally variable and irregular in shape. The correction tensor just made it simpler to track these odd shapes.
The corrected formula shifts global environmental monitoring.
The accurate prediction of irregular nanoparticle behavior enables medical experts to design effective interventions for respiratory diseases.
Improved understanding of how viruses move through the air will help curb viral spread.
Furthermore, climate science can improve atmospheric warming models.
Ultimately, by using precise mathematics, global leaders can implement better public health policies. Climate solutions will be better targeted to protect the planet.
