Abstract:
:Antioxidative enzymes (superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX)), as well as lipid peroxidation and proline were studied in moss Brachythecium piligerum Card. collected from different sites in Shanghai, China, to validate the physiological parameters as biomarkers of atmospheric heavy metal pollution. Results demonstrated that the responses of POD and CAT activities, as well as MDA and proline contents were in accordance with the heavy metal contents in mosses. That is, POD activity, MDA, and proline content were activated and CAT activity was inhibited in heavier polluted sites, indicating that POD and CAT activities, and MDA and proline contents could be used as biomarkers for biomonitoring atmospheric heavy metal pollution.
