| Grassland soil A | 15.2±1.5 | 0.08±0.007 |
| Grassland soil B | 19.6±0.6 | 0.10±0.003 |
| Forest soil | 14.9±0.7 | 0.07±0.003 |
| Maize field soil | 9.5±0.7 | 0.05±0.004 |
| Barley field soil | 5.5±0.7 | 0.03±0.003 |
| Marine sediment A | 6.4±0.8 | 0.03±0.004 |
| Marine sediment B | 5.0±0.1 | 0.03±0.001 |
| River sediment | ND | ND |
| Lake sediment | ND | ND |

DMS production is expressed as nmol DMS per g sample or nmol DMS per ml sample in case of seawater samples. Values shown are the average of three biological replicates with respective standard deviations ND, not detected.
