where Cin and Cout are the contaminant concentration in the inflow and
outflow, respectively, Jin and Jout are the inflow and outflow water fluxes,
respectively, and ttot is the total time of a storm.
Organic matter in the compost and the discharge was further analyzed
for chemical structure and functional groups by spectroscopic
methods. Finally, chemical speciation modeling was used to quantify
the interactions between organic matter and copper.
