摘要

•Oil sands development has led to increasing N emissions and regional N deposition.•Can δ15N of bog plant or lichen tissues indicate an oil sands emission influence?•δ15N (‰) and N (mg/g) in Evernia mesomorpha may suggest an oil sands influence.•Scarce data on oil sands N source δ15N signatures preclude definitive interpretations.
