Atmospheric pollution has been an area of concern for scientists and environmentalist for decades. The air we breathe is a mixture of gases, moisture, and suspended particles emanating from various sources.

Human activities like burning of fossil fuels, transportation, and industrial activities have been the primary sources of air pollution. Besides affecting the respiratory system, atmospheric pollution can also be detrimental to kidney health.

How Atmospheric Pollution reaches Kidneys

Kidneys are some of the most vital organs in the human body. They sift out waste and eliminate excess fluids to maintain homeostasis.

However, the scientific community has recently found that atmospheric pollution may hamper the kidneys’ ability to function effectively. Atmospheric pollution can affect the kidneys in several ways.

Airborne Particles

Airborne particles from pollution deactivate antioxidants that protect the kidneys. Some particles like sulfate, nitrate, and ammonium cations accumulate in the kidneys and interfere with their functioning.

Also, inhalation of Carbon monoxide (CO), a gaseous pollutant, may alter the blood flow to the kidneys and reduce the oxygen level, leading to a deteriorated kidney function.

Heavy Metals

Heavy metals in polluted air like cadmium and lead can enter the kidney through the bloodstream. These metals accumulate in the kidney leading to oxidative stress, inflammation, and disrupted cellular maturation.

Lead can impair the glomerular filtration rates (GFR) – a measure of kidney functionality. Prolonged exposure to heavy metals could lead to acute kidney injury, chronic kidney disease, and some cancers of the urinary system.

Ozone

Ozone (O3) is a powerful oxidizing agent responsible for respiratory distress and other respiratory conditions. When inhaled, Ozone induces an inflammatory response in the lungs that spill into the bloodstream and affect the kidneys.

Studies indicate that high levels of Ozone can cause acute kidney injury and have long-term effects on the glomeruli that act as a kidney filter.

Nitrogen Oxides

Nitrogen oxides, mainly NO2, are released to open air industrial sites and the exhausts of vehicles using diesel fuel.

Nitrogen oxides damage the cells in the kidneys by causing oxidative stress and reducing the renal artery’s diameter, subsequently reducing the blood supply to the kidneys. Long periods of exposure to Nitrogen oxides can cause proteinuria, a condition that leads to the leakage of protein into the urine.

Preventing Kidney Damage from Atmospheric Pollution

The best way to protect kidneys from atmospheric pollutants is through prevention. Here are some suggestions:.

Reduce Exposure

Reducing exposure to air pollutants may significantly reduce the risk of kidney damage. Since it may be difficult to eliminate all the sources of pollutants, it is advisable to avoid outdoor activities during periods of high pollution.

Avoid areas with high traffic or industrial sites.

Wear a mask

A Medical mask traps dust, bacteria, and allergens and will filter most pollutants effectively. Wear a mask when you must be outdoors on days when environmental conditions are unfavorable.

Healthy Lifestyle

Leading a healthy lifestyle such as eating well, regular exercise, and abstaining from smoking and excessive alcohol intake can reduce the risk of kidney injury from atmospheric pollution.

A balanced diet with fewer processed foods will help preserve the function of the kidneys.

Invest in Air Purifiers

Installing air purifiers in your home or workplace can reduce pollution levels. High-efficiency particulate air (HEPA) filters can remove almost 100% of fine particulate matter that can harm your kidneys.

Conclusion

Protecting our kidneys from atmospheric pollution is crucial for our overall health. We hope that the suggested tips can help you reduce the risk of kidney injury from air pollution. Prevention is key.

We all have a role to play in protecting our environment for ourselves and future generations.
