- •
Paddy fields hold significantly lower level of PCBs than drylands, especially highly-chlorinated PCBs.
- •
Microbial dechlorination of PCBs is favored under flooded conditions in paddy field.
- •
Aerobic biodegradation of PCBs is benefited under dry conditions in paddy field.
- •
PCBs dechlorination rate is accelerated in rice planted paddy field compared to the unplanted one.
- •
Alternating anoxic–oxic environment in paddy field led to the sequential aerobic–anaerobic transformation of PCBs.
