Burning is a common method to dispose agricultural biomass residue. This practice widely used by farmers during pre- and post-harvest seasons for crops such as wheat, rice, grass seed, soy, cotton, sugarcane, corn. Farmers choose this because it cost time effective. These burning activities emit several types of pollutants into the atmosphere, including CH4, SOx, NOx, CO, CO2, particulate matter different sizes (i.e., PM1, PM2.5 PM10). Globally, United States America ranks third, preceded China India, in greenhouse gas emissions due activities. According 2020 U.S. National Emissions Inventory, field burnings produced 67,309.81 tons i.e., approximately 20% total emissions. The main aim review paper summarize existing literature on its effect air quality continental USA. utilizes databases Web Science, Science Direct, PubMed ProQuest endeavor. Various their emission factors are presented each type crop. Additionally, also compiles available data from inventories characterize spatial temporal patterns pollutant resulting burning.

Furanoids are a class of reactive volatile organic compounds that major products from the pyrolysis and combustion biomass polymers, including cellulose, hemicellulose, lignin. Biomass burning is an atmospheric source furanoids increasing in frequency intensity throughout regions world. Once emitted to atmosphere, may react with oxidants form secondary pollutants hazardous human health, ozone (O3) aerosol (SOA). This review comprehensive assessment literature between 1977 present describing emissions fate wild, prescribed, domestic fires. The organized by presenting physical properties key first, followed summary biopolymer reactions lead furanoid formation. Next, factors compiled across typical fuels consumed highlight species smoke. We next available kinetic degradation mechanism data characterize reaction rates, gas-phase products, SOA formed as result OH, NO3, O3, Cl radicals. then describe studies have focused on evaluating chemistry their impacts air quality using combination field observations model simulations. conclude perspective identifies future research directions would address gaps improve understanding processes.

Abstract. Biomass burning emits large numbers of organic aerosol particles, a subset which are called tarballs (TBs). TBs possess spherical morphology and unique physical, chemical, optical properties. They recognized as brown carbon thereby having implications for climate through the absorption solar radiation. Aerosol particles were collected from wildfire agricultural fire smoke sampled by NASA DC-8 aircraft during FIREX-AQ campaign in western US July to September 2019. The current study developed an image analysis method applying deep learning distinguish other round that deformed on substrate, based their morphological characteristics transmission electron microscopy images.
