In recent years, the issue of air pollution has become a growing concern, particularly with regard to PM2.5. These fine particles, measuring 2.5 micrometers or smaller, are primarily generated from combustion processes such as power generation, industrial activities, and vehicle emissions. Many of these particles contain harmful substances like heavy metals and organic compounds, making them especially dangerous to human health. Coarse particles, typically ranging from 2.5 to 10 micrometers, are often derived from sources like road dust and construction activities. In contrast, PM2.5 is more insidious due to its ability to penetrate deep into the lungs and even enter the bloodstream. This makes it a significant contributor to respiratory and cardiovascular diseases. The concept of PM2.5 was first introduced by the United States in 1997 as a way to better monitor and address the health risks posed by fine particulate matter that had previously been overlooked in older air quality standards. Since then, PM2.5 has become a critical indicator for assessing and managing air pollution worldwide. As of 2010, many countries around the globe had not yet implemented PM2.5 monitoring systems. While some regions in the U.S. and Europe had already adopted this standard, most nations were still focusing on monitoring larger particles, such as PM10. This gap in monitoring highlighted the need for more comprehensive air quality assessments. Particulate matter refers to tiny solid or liquid particles suspended in the air. In environmental science, these particles are considered major pollutants that can have serious health impacts. Particles smaller than 10 micrometers, known as respirable particles, can be inhaled and accumulate in the lungs, leading to long-term health issues. Among these, PM2.5 is the most hazardous because of its small size, allowing it to reach the deepest parts of the lungs. Scientists measure PM2.5 levels in micrograms per cubic meter of air. Higher concentrations indicate worse air quality and greater health risks. In many parts of China, especially in industrialized regions like North China, PM2.5 constitutes a large portion of airborne particles. However, at the time, China's Air Pollution Index (API) did not include PM2.5 in its monitoring system, limiting the ability to fully assess air quality and protect public health.
