Rice is an important cash crop, and it is estimated that 739 million tonnes were produced in 2016, leaving a significant amount of residue burned after harvest in the field, such as roots, stubbles and straw. Over recent decades, it is an emerging and important issue contributing to the intensification of smog, especially in Asian countries. Open burning is a common practice in rice straw management in Asia. Mass ratio between the obtained biomass waste and the rice produced is equal to 1.76 while the total waste burned in the world is about 20%. From these data, it is clear that the annual burnt biomass of the world is equal to 260 million tons. This study determines the amounts of atmospheric organic and inorganic micropollutants emitted during the burning of rice straw biomass, compared to wheat straw (PCDD/Fs, dl-PCBs, PAHs, metals, PM).

Abstract
Rice is an important cash crop, and it is estimated that 739 million tonnes were produced in 2016, leaving a significant amount of residue burned after harvest in the field, such as roots, stubbles and straw. Over recent decades, it is an emerging and important issue contributing to the intensification of smog, especially in Asian countries. Open burning is a common practice in rice straw management in Asia. Mass ratio between the obtained biomass waste and the rice produced is equal to 1.76 while the total waste burned in the world is about 20%. From these data, it is clear that the annual burnt biomass of the world is equal to 260 million tons. This study determines the amounts of atmospheric organic and inorganic micropollutants emitted during the burning of rice straw biomass, compared to wheat straw (PCDD/Fs, dl-PCBs, PAHs, metals, PM).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
