| Responding parameter group | Physico-chemical parameters |
| Responding parameter | DOC |
Response description
Rising temperatures in combination with declining acid deposition cause increasing DOC concentrations.
Secondary effects
Increasing DOC and water colour may have impacts on freshwater biota and drinking water quality. E.g. increasing water colour might change light availability and thus primary production.
Relevant ecoregion(s) according to Illies
Central (14) and Eastern Lowlands (16), UK (18)
Suggested indicator
DOC
Justification of indicator
Incorporated into routine water quality monitoring
