The risk for bone fractures steadily increases as levels of air pollution, specifically particulate matter smaller than 2.5 micrometers (PM 2.5), go up. The study tracked hospital admissions among 9.2 million Medicare recipients in the Northeast over eight years and revealed that areas with the highest concentrations of PM 2.5 had almost 5% higher rates of bone fractures compared to those with the lowest. Another study analyzed levels of parathyroid hormone, which is crucial to bone health, in 692 middle-aged low-income men in Boston. The research found that individuals living in locations with higher levels of air pollution had lower concentrations of parathyroid hormone and lower levels of bone mineral density. The senior author, Andrea A. Baccarelli, a professor of environmental medicine at the Columbia University Mailman School of Public Health, likened air pollution to diluted smoking. He stated that even at pollution levels considered acceptable by the Environmental Protection Agency, there is still an increased risk of cancer, cardiovascular disease, bone mineral density loss, and other health issues associated with pollution. This study highlights the devastating effects of air pollution on human health, including bone fractures and loss of bone mineral density. As such, it is essential to take necessary measures to curb air pollution by reducing emissions from industrial and transportation sectors while promoting sustainable practices. Additionally, individuals can take steps like using public transportation or buying eco-friendly products to reduce their carbon footprint and support efforts to mitigate air pollution's harmful effects. 【重点词汇&词组】 1. air pollution（n.）空气污染 2. increase（v.）增加 3. risk（n.）风险 4. bone fractures（n.）骨折 5. p
