Continuous fluorescence assessment of organic matter variability on the Bournbrook River, Birmingham, UK.

The article presents a study on a 2-week experiment on dissolved organic matter (DOM) at Bournbrook River in Birmingham, England. Its objective is to present an hourly resolution of DOM character and concentration by measuring spectrophotometric, physiochemical, electrical conductivity, and isotopic parameters of the river. The results of the study had sub-daily variations in both organic matter concentration and characteristics. Moreover, it shows that after relatively high-magnitude precipitation events organic carbon concentration increased with simultaneous increase in intensity of both humic-like and tryptopham-like fluorescence.
