Air pollution contains fine particulate matter, or PM2.5, which is a cocktail of microscopic particles because these particles are virtually weightless, they can stay in the air longer, causing humans to unavoidably inhale them on a regular basis without knowing it. PM2.5 can lead to serious health effects when inhaled often.
Reviewing Medicare claims data and air-quality data from the Centers for Disease Control and Prevention, the study’s authors found a positive association between CKD rates and PM2.5 concentration. According to figures cited in the new research, chronic kidney disease afflicts more than 27 million Americans. People with CKD have an eightfold increased risk of cardiovascular mortality.
PM2.5 is almost impossible to avoid, we encounter air pollution from many simple everyday activities, such as cooking and driving. Other contributors are smoking, burning wood, packaged spray products, household appliances, industry and vehicle emissions. Air pollution also contains heavy metals such as lead, mercury and cadmium which are can affect the kidneys.
Researchers examined several prior studies on the issue, including an effort conducted in select coal-mining areas of Appalachia that found a 19 percent higher risk of CKD among men and a 13 percent higher risk in women compared with those who lived in counties with no mining. If you live in heavily polluted areas, consider wearing masks that cover nose and mouth, limit hours outside and limit long hours commuting to work in high traffic.
