Abstract

This study was performed to investigate if elevated $CO_2$ affects the residue pattern of $^{14}C$ in the soil environment after $^{14}C$-carbaryl treatment $^{14}C$-carbaryl was applied on the rice plant-grown greenhouse soil exposed to atmospheric and elevated $CO_2$ conditions. $^{14}C$-radioactivity was measured in the rhizospheric soil and rice straw samples six months after $^{14}C$-carbaryl application. Significantly high radioactivity was observed in the soil exposed to atmospheric $CO_2$ as compared to that in the soil exposed to elevated C(h. Background level of radioactivity was observed in rice plant samples. These observations suggest the possibility that elevated $CO_2$ may affect residual radioactivity of $^{14}C$-carbaryl in the soil rather than that in the plant.
