Abstract
Exposure to moderate concentrations (90–500 μg SO 2 m −3) of SO 2 for 5–30 days caused a decrease in the photosynthetic rate. Only the lowest concentration (30 μg SO 2 m −3) increased photosynthesis. There was hardly any recovery in photosynthesis after the exposure. All exposure concentrations increased dark respiration. However, the lowest concentration had the smallest effect. Exposure to high concentration (2320 μg SO 2 m −3) of SO 2 for 5 h caused a strong decrease in the photosynthetic rate but there was a complete recovery within 2 weeks.
