The effects of the heavy metals copper (Cu), zinc (Zn), and lead (Pb) on the chlorophyll content of two mosses Thuidium delicatulum (L.) Mitt. and T. sparsifolium (Mitt.) Jaeg., as well as leafy liverwort Ptychanthus striatus (Lehm. & Linderb.) were examined to understand the impact of metal
This paper studied the accumulation and scavenging of active oxygen radicals, injury of photosynthetic system and membrane system, and changes of antioxidant enzyme system in Thuidium cymbifolium cells under single and combined stress of Pb and Ni. Under low concentration of Pb and Ni (Pb < 0.1 mmol
Responses of Hypnum plumaeforme, Thuidium cymbifolium, and Plagiomnium cuspidatum to short-term (96 h) BDE-47 and BDE-209(0, 0.005, 0.05, 0.5, and 5 μM, respectively) stress were investigated. Both BDE-47 and BDE-209 increased the lipid peroxidation in the three moss species, malondialdehyde (MDA)
This paper dealt with the effects of Pb2+, Cd2+ and their combined pollution on the contents of chlorophyll, potassium and calcium in Thuidium cymbifolium. The results showed that except at 0.1 mg Cd2+.L(-1), the chlorophyll content decreased with increasing Pb2+ and Cd2+ concentrations, which was
