Alkaline stabilized biosolids contain a wide range of emerging substance of concern and their land application araise the concern over theri fate in soil and ecotoxisity. We investigated the effects of primary treated (RB) and alkaline-stabilized biosolids (ATB) on concentration of 5 main substances of concern in soil and corn tissue on Mt.Hope, Lindsay, and Bible Hill soils in, Canada. Soils were amended with ATB at 14, 28 and 42 Mg ha^-1 dry weight, RB at 42 Mg ha^-1 dry weight, inorganic fertilizer (FERT), and control (CONT) with zero N. Corn was seeded into pots in a controlled environment chamber (18-27 ^oC; 16h daylight), and above ground biomass was harvested after 10 weeks.
