It is common practice worldwide to use open field burning to clear agricultural fields of rice straw and other vegetative residues, and for disease and pest control. This burning produces smoke, which contains respirable particulate and gaseous components. Currently, there is no specific information available on the direct effect of rice straw smoke (RSS) exposure on respiratory health effects, even though epidemiological data indicate that this issue requires investigation. The objective of this project was to investigate the effects of controlled exposure to RSS on human respiratory health.
