Scientists think the even the short-term exposure to pollution can lead people to the hospitals. They are suggesting changing global air quality. The particle pollution with a diameter of 2.5 micrometers is a mixture of solid and liquid droplets in the air. The thickness is 1/20th of the hair thickness, and people cannot see it. However, it can travel past the body’s usual defenses. This type of pollution could be very harmful to human health. Because the particles can be stuck in the human lungs and can make their way into the bloodstream. Moreover, it can cause severe respiratory issues and other diseases.
This type of particles can generate through construction sites, agriculture, unpaved roads, and many more. Researchers looked at more than 90 million records from the hospitals to study the risk of this pollution on human health. They are trying to study the effect of the short term exposure to this pollution using hospital data from 2000-2012. Study author Francesca Dominici said, “It took enormous computational power to process the data.” Scientists used Harvard Supercomputer to analyze the massive data. They found 200 causes of hospitalization due to pollution. Dominici and her team found a correlation between particle pollution and cardiovascular problems. However, they found some of the unexpected correlations to diseases such as Kidney failure, septicemia, urinary tract infection, and skin infection.
Every 1-microgram cubic meter increase in exposure to pollution will increase the annual hospital admissions by 2050. The health care cost will be massive. Domenici said, “With the tiny increase in exposure, there are enormous healthcare costs.” The study also shows the risk of diabetes, thrombophlebitis, and thromboembolism. Hence, scientists are suggesting revising WHO air quality guidelines. President Donald Trump pledged in 2017 to promote clean air and water. However, governments need to make a solid plan to clean the air. Otherwise, pollution can lead to a wide range of severe diseases.
