Introduction

Large-scale biochar application may provide sustainable pathways to improve
productivity and carbon storage of agricultural soils or remediate
contaminated lands. However the environmental impacts of large-scale
biochar application needs to be investigated to evaluate the tradeoffs and
synergies. In this preliminary research we used wind tunnel studies to
investigate the dust emission potential of biochar-amended soils. The increase
in airborne dust can impact human health, particularly since biochar particles
can sorb bioavailable contaminants.
