In recent decades, as wildland fire occurrence has increased in the United States, concern about the emissions produced by wildland fires has increased as well. This growing concern is evidenced by an increase in scientific articles investigating effects of wildland smoke on public health, and ongoing research projects assessing wildland smoke hazards. We reviewed primary literature evaluating wildland smoke in the United States and determined that the vast majority of available literature addresses the northwestern and southeastern US. We discovered that a significant knowledge gap exists for the Great Plains, a region where wildfire and prescribed fire occur frequently. In this region, wildfire and prescribed fire are important economically, ecologically, and culturally. Given the paucity of data regarding emissions from Great Plains fuels and the increase in fire occurrence in the region, we suggest that more active research is needed to fill this gap.

美国大平原地区的烟雾：一种日益增多的现象，对政策和健康有潜在影响

近几十年来，随着美国野火的发生增加，人们对野火产生的排放的关注也增加了。越来越多的科学证据表明，对野外烟尘对公共健康的影响进行调查的科学论文以及评估野外烟尘危害的正在进行的研究项目证明了这一日益增长的担忧。我们回顾了评估美国野地烟气的主要文献，并确定了绝大多数可利用的文献针对的是美国西北部和东南部。我们发现大平原地区存在巨大的知识差距，大平原地区经常发生野火和明火。在该地区，野火和明火在经济，生态和文化上都很重要。
