The experts combined traditional air quality monitoring observations, satellite-based meteorological and air pollution detectors, and statistical and machine learning methods to more accurately assess PM 2.5 concentrations worldwide. The researchers also discovered that unsafe PM 2.5 concentrations exhibited different seasonal patterns, with northeast China and north India facing high concentrations in winter, and eastern areas in northern America being exposed to more air pollution in summer. According to Professor Guo, this study is important since it provides a deep understanding of the current state of outdoor air pollution and its possible impacts on human health. “With this information, policymakers, public health officials, and researchers can better assess the short-term and long-term health effects of air pollution and develop air pollution mitigation strategies,” he concluded. —By Andrei Ionescu, Earth.com Staff WriterCheck us out on EarthSnap, a free app brought to you by Eric Ralls and Earth.com.
