野火引发的空气污染对公众健康构成潜在威胁。专家建议采取多项防护措施应对有害烟雾。
根据美国环保署空气质量指数，当污染水平达到100-150时，敏感人群会感到不适 [1]；超过150时，空气质量对所有人均有害 [1]。Buffalo大学医学院呼吸科负责人Sanjay Sethi博士建议，心脏或肺部存在问题的人群在污染严重时应避免外出，或选择佩戴N95口罩进行防护 [1]。
N95口罩在防护中具有明显效果。Boston大学气候与健康中心研究科学家Jennifer Stowell指出，N95口罩可以过滤掉颗粒物中的90-95% [1]。
室内防护同样重要。哈佛大学健康建筑项目主任Joseph Allen建议使用低成本室内空气质量监测仪 [1]，以便及时了解室内污染状况并采取相应措施改善室内通风过滤。
Wildfires are creating dangerous air quality conditions that pose health risks to the public. Experts recommend several protective measures to minimize exposure to harmful smoke.
According to the EPA's Air Quality Index, readings between 100 and 150 indicate unhealthy conditions for sensitive groups, while readings above 150 become hazardous for everyone. [1] People with existing heart or lung conditions should particularly take precautions; Dr. Sanjay Sethi, head of pulmonology at Buffalo University's School of Medicine, advises those with cardiovascular or respiratory issues to either avoid going outside or wear N95 masks when necessary. [1]
N95 masks offer substantial protection when worn properly. Jennifer Stowell, a research scientist at Boston University's Climate and Health Center, notes that these masks can filter out 90 to 95 percent of particulate matter. [1]
For indoor protection, experts recommend monitoring air quality inside your home. Joseph Allen, director of the Healthy Buildings Program at Harvard University, suggests using low-cost indoor air quality monitoring devices. [1] Improving ventilation and filtration systems in living spaces can also help reduce exposure to wildfire smoke infiltration.
