  1. aThe percentage of DNRA in the total NO3 − reduction (denitrification + DNRA); the rest studies in the column show the percentage of DNRA in the NO3 − reduction (denitrification + DNRA + anammox). bNA represents no available data. cThe percentage of DNRA in the total nitrate reduction were estimated where rates of denitrification and anammox in some sites of the Yangtze Estuary were used to serve as data in this study.
