主 题:Atmospheric heavy metal pollutions Sabina chinensis Platycladus orientalis Physiological responses
摘 要:Heavy metal(Cu,Mn,Zn,Pb,and Cd)concentrations were measured in the leaves of Sabina chinensis and Platycladus orientalis collected from urban,suburban,and rural sites in Tianjin,*** pigment contents,reactive oxygen species content,malondialdehyde(MDA)content and antioxidant enzyme activity were investigated,providing physiological response *** comparison of the sites revealed that urbanization significantly influenced the heavy metal concentrations in both plant *** the rural site,both plant leaves exhibited the lowest heavy metal *** highest Cu,Mn,and Zn concentrations were found in *** leaves from the urban site;the highest Pb and Cd concentrations were found in *** leaves from the urban *** results indicate that the urban site contained larger heavy metal concentrations in the plant leaves that may reflect the anthropogenic emission *** is also found that *** may be used to monitor airborne heavy metal pollution because it is highly quick response to heavy metals,while *** may be used for mitigation due to its high *** results of this study can contribute to the development of monitoring and environmental management plans by providing information on sensitive and resistant tree species for city greening in North China.
