Database of in-plume emission factors from open demilitarization of military ordnance

A searchable database of emission factors from open burning, open detonation, and static firing of military ordnance and rocket motors has been developed and made available. Sampling and analytical results since 2010 have been compiled from seven campaigns in the USA and Canada at four different sites. Various ordnance types were used for multiple test scenarios varying location, soil covered/uncovered, metal-cased and uncased, and net explosive weight. Target compounds include, variously, particulate matter, metals, energetics, volatile organic compounds, and others. Data were primarily derived from unmanned aerial sampling methods using ordnance charge sizes and procedures representative of operational demilitarization operations. The database includes 1,212 emission factors for 39 different types of munitions and an array of pollutants where open burns accounted for 514 scenarios, static firing for 83, and open detonation for 614. The database will be of use for risk evaluations, environmental reporting requirements, and demilitarization operations.本研究已构建并公开一套可检索的数据库，收录军事弹药与火箭发动机露天焚烧（open burning）、露天引爆（open detonation）及静态点火（static firing）过程产生的排放因子。该数据库整合了2010年以来，在美国和加拿大共4处场地开展的7次采样测试活动所获得的采样与分析结果。测试过程中采用了多种弹药类型，设置了涵盖场地条件、土壤覆盖/裸露状态、金属弹壳/无弹壳以及炸药净重量等多种变量的多类测试场景。目标检测化合物涵盖颗粒物、金属、含能物质、挥发性有机化合物等多类物质。数据主要采用无人机空中采样方法获取，采样所用的弹药装药量与操作流程均贴合实际的军事装备退役处置作业场景。该数据库共收录39类弹药的1212项排放因子，涉及多类污染物，其中露天焚烧场景514个、静态点火场景83个、露天引爆场景614个。本数据库可应用于风险评估、环境合规报告编制以及军事装备退役处置作业等领域。
