[Objective] The aim was to discuss the feasibility of using Acorus calamus to restore PAHs pollution. [Method] A. calamus L.was cultured in synthetic wastewater containing different concentrations of naphthalene. The effects of naphthalene stress on growth,chlorophyll content,PRO content and MDA content in leaves of A. calamus were studied. [Result] The height and biomass growth of A. calamus decreased significantly under naphthalene stress,while chlorophyll content in the leaves increased significantly; PR...
