Influence of compost addition on lead and arsenic bioavailability in reclaimed orchard soil assessed using Porcellio scaber bioaccumulation test

► We evaluate the impact of compost on Pb and As bioavailability in soil. ► As and Pb bioaccumulation in isopods as a bioavailability test. ► Compost lowered Pb and increased As bioaccumulation. ► Bioaccumulation test with isopods proposed as screening tool for Pb and As bioavailability.
