This EMBRACE SEED project is focused on the study of halogen emissions and their impacts on the atmosphere of Salt Lake City Utah. The project seeks to quantify the extent of halogen-initiated chemistry through highly chemically speciated measurements of halogens, volatile organic compounds and their oxidation products, and particulate matter in the Salt Lake City region. The high level of regional halogen emissions makes the atmospheric chemistry in this airshed different from that of any other city in the United States. This proposal targets the quantitative relationship between halogen chemistry and air quality, in order to better understand how halogen emissions might impact the health of people in the region.The objectives of this research are to quantify: (1) the relative amounts of chlorine, bromine, and hydroxyl radical-initiated oxidation in the Salt Lake City airshed; and (2) the contribution of chlorine and bromine radical-initiated chemistry to particulate matter concentrations in the region. The two-year project is a collaborative effort between Weber State University and Aerodyne Research Inc. This partnership with industry will provide Weber State undergraduates access to state-of-the-art atmospheric chemistry instrumentation for six weeks of local field measurements in the summer 2024, during which time the NOAA-supported Utah Summer Ozone Study will be making many complementary measurements of key chemical species in the region.Weber State serves a dual mission: operating both as a four-year open-enrollment public university and as a regional public community college. Because of this mission, the majority of Weber State students are undergraduates who work full time, have a family, or have pursued a non-traditional path to a higher education. This project will train and support five undergraduate students directly and provide data for use in future undergraduate courses and student research projects.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个拥抱种子项目的重点是研究卤素排放及其对犹他州盐湖城大气的影响。该项目旨在通过高度化学指定的卤素，挥发性有机化合物及其氧化产物以及盐湖城地区的颗粒物来量化卤素引起的化学的程度。高水平的区域卤素排放使这台空调的大气化学与美国任何其他城市不同。该提案针对卤素化学与空气质量之间的定量关系，以便更好地了解卤素的排放可能如何影响该地区人的健康。这项研究的目标是量化：（1）盐湖城空气中的氯，溴和溴和羟基自由基激发氧化的相对量； （2）氯和溴自由基启动的化学对该地区颗粒物质浓度的贡献。 The two-year project is a collaborative effort between Weber State University and Aerodyne Research Inc.
