Abstract Emissions of sulfur gases to the atmosphere from 42 types of terrestrial higher plants were measured by using the closed chamber method. CH3SCH3, CH3SH, COS, H2S, CS2, and n-CH3CH2CH2SH were emitted from the plants. CH3SCH3 was predominantly emitted from most of the plants, and the largest emission was 455 ng S kg-1 dry wt. min-1 from snow-on-the-mountain (Euphorbia marginata). CH3SH was predominantly emitted from liliaceous plants such as Chinese chive (Allium tuberosum) and Asparagus (Asparagus officinalis) and cruciferous plants. The largest emission was 1,380 ng S kg-1 dry wt. min-1 from Chinese chive. n-CH3CH2CH2SH was predominantly emitted from liliaceous plants such as leek (Allium fistulosum) and onion (Allium cepa). COS was mainly emitted from nasturtium (Tropaeolum majus). Key Words: biogenic sulfur gas emissioncarbonyl sulfidedimethyl sulidemethanethiol n-propanethiol
