Effects of different order spiking on bioavailability and ecological risk of phenanthrene in mangrove sediment-biochar system

Biochar shows unique advantage in decreasing the bioavailability of phenanthrene and has huge potential into the in-situ remediation of contaminated sediment. The different order spiking influences the bioavailability and ecological risk of phenanthrene, this study provides a comprehensive investiga...
