Effect of heavy metal stress on antioxidative enzymes and lipid peroxidation in leaves and roots of two mangrove plant seedlings (Kandelia candel and Bruguiera gymnorrhiza)

Effect of excess iron and copper on physiology of aquatic plant Spirodela polyrrhiza (L.) Schleid

“…Our results showed that with the increasing metal concentration, the MDA content increased, which is similar to the effect of heavy metals on other higher plants (Sinha and Saxena, 2006;Singh et al, 2006;Zhang et al, 2007). Proline accumulates in a variety of plant species in response to stresses such as drought, salinity and extreme temperatures.…”

Bio-Monitoring of Roadside Plants and Their Response to Vehicular Pollution- A Physiochemical Appraisal.

“…As MDA is a well known indicator of oxidative stress it is possible to state that Macarangapeltatais highly under the influence of oxidative stress as compared to other plants. The present results substantiate the earlier studies by Zhang et al, (2007), i.e., the free radical generated during pollution cause damage to vital membranes and membrane bound proteins involved in energy producing processes. …”

Effect of lead acetate toxicity on experimental male albino rat

“…Although many enzymes are inhibited by Pb 2+ , no specific inhibition has been identified as the biochemical lesion. Antioxidant enzymes were affected by higher doses of Pb 2+ [18,52] . Heavy metals induced hepototoxicity through the depletion of glutathione and protein, resulting in enhanced production of reactive oxygen species such as peroxide ion, hydroxyl radical and H 2 O 2 .…”
