Preliminary inventory of atmospheric emissions (SO2, NOx and TSP) from different industrial sectors in Costa Rica

The use of fuels, urbanization growth, and economic development have influenced the generation atmospheric pollutants such as NOx (nitrogen oxides), SO2 (sulfur dioxide), TSPs (Total Suspended Particles). Costa Rican industrial sector has different category companies glass melting manufacturing food products clothing, which release emissions these into atmosphere. main objective this research is to generate a preliminary inventory (NOx, SO2, TSP) from sectors in Rica. was conducted 2019 included samplings measurements chimneys production processes (companies) 2014 2015. sampling corresponding measurement pollutant concentrations were using Testo 350 measure an APEX portable particle counter quantify TSPs. Data tabulated Microsoft Excel, while graphics generated R programming language studio interface. entitled “manufacturing products” presents highest amounts pollutants, with values equal 1246.14 tons/year, 1959.54 tons/year 651.01 for NOx, TSP, respectively, 2014; 2,622.14 3,257.64 346.40
