Answer 2

Sulphur dioxide is toxic to plant at or above 01-03ppm.

Explanation:

Sulphur dioxide is toxic to the plants at or above 01-03ppm. Plants are very sensitive to sulphur dioxide. Though sulphur is an essential nutrient for plant growth, even a bit of excess of sulphur dioxide affects plants, directly and indirectly. It inhibits photosynthesis in plants by disrupting the photosynthetic mechanism. It can also cause foliar injury in plants in higher concentrations.
