英文摘要	Carbon capture and storage (CCS) is an effective means of mitigating anthropogenic CO2 emissions in the atmosphere. However, it is important to consider the risks of CO2 leakage from storage sites and their potential impacts on near-surface ecosystems. We explored the impact of increased soil CO2 concentrations on sunflowers (Helianthus annuus Linn.), a main oil crop, using pot experiments. The results indicate that the crude fat content of the sunflowers decreased by 3.62%, whereas the crude protein content and linoleic acid contents increased by 4.12% and 13.98%, respectively; sunflower yields remain unchanged under 1500 g m(-2) day(-1) CO2 leakage. We confirmed that the sunflower oil content decreased because of higher soil CO2. A decrease in sunflower oil production rates will reduce their commercial value. The elevated crude protein and linoleic acid contents increased the nutrients in sunflower meal and edible oil, indicating that increased CO2 in soil caused by CCS leakage can improve the quality of sunflower oil to some extent. Considering the tolerance of sunflowers to CO2 leakage, planting sunflowers in CCS project areas is a feasible solution for addressing CO2 leakage.
