摘要：

Regression equations relating u. v. absorbance to total organic carbon (TOC) in river water are compared for streams draining two upland catchments in north-east Scotland which have similar climate, topography and land use but contrasting acidic and basic parent materials. A comparison is also made of regression equations for individual tributaries contributing to the main streams in each catchment. Reasons for observed differences are suggested. Changes in u. v. absorbance vs TOC relationships through storm events are discussed, and the problems associated with using TOC/absorbance relationships to monitor changes in TOC with time through storms are briefly considered.
