On the chemical mass-balance in estuaries
WebExpanding knowledge of degradation kinetics coupled with significant improvements in measurement precision of dissolved organic carbon (DOC) necessitates a review of factors that influence its cycling in estuaries. A one dimensional, time‐dependent estuarine model was used to ascertain how sinks and sources of DOC produced conservative and … WebMass balance calculations suggest that widely applied sequential extractions do not separate Fe-rich authigenic clay minerals from reactive Fe oxides and carbonates.

WebOne of the major advantages of the ISCC PLUS mass balance approach is the possibility to gradually increase the share of bio-based and/or circular feedstocks in the production process. In addition, the calculated share of bio-based and/or circular feedstocks can be attributed on an equivalent basis to one or several outputs. On this basis, the ...
