摘要

An inventory of air pollutant emissions from forest and agricultural fires for the period of January 1 to August 30, 2000 is presented. Emissions were estimated for three Northeastern Mexican States: Coahuila, Nuevo Leon and Tamaulipas. The inventory takes into account the most important compounds released to the atmosphere during an outdoor fire: carbon monoxide (CO), methane (CH4), non-methane hydrocarbons (NMHC), ammonia (NH3), nitrogen oxides (NO_x) and particulate matter (PM). Particulate matter was categorized into PM_(10) and PM_(2.5). Almost all outdoor fires registered for the period of interest were wildfires. Procedures employed in this study were based on previous work conducted to estimate a similar emissions inventory for the State of Texas in the U.S. Data from CONAFOR (Mexican Forest Agency) and Proteccion Civil (Mexican Emergency Service) was used to establish the location, duration and area burned of reported wildfires and prescribed fires. The database was complemented with fires identified using satellite images. Here a hierarchical procedure was used to analyze the Advance Very High Resolution Radiometer (AVHRR) data sets that were obtained. Fuel loadings were estimated for each fire event based on available landuse data. Emission factors for each compound were based on literature data. Agricultural fires were considered only for the State of Tamaulipas, where sugar cane plantations are an important source of emissions. Neither in Nuevo Leon nor in Coahuila agricultural or slash burning was a relevant source of emissions, as the results from the surveys conducted showed. Emissions estimated are reported by state and month. The results were further analyzed considering the prevailing meteorological conditions of the region, mainly wind speed and direction. Implications of these conditions on transboundary air pollution are discussed. Along the same line, back- and forward-trajectory analyses were conducted to identify the impacts of major fire events during the period of interest.
