Photosynthetic changes and antioxidant activity to oxidative stress were evaluated in sour orange (Citrus aurantium L.) leaves subjected to lead (Pb), copper (Cu) and also Pb + Cu toxicity treatments, in order to elucidate the mechanisms involved in heavy metal tolerance. The simultaneous effect of Pb− and Cu on growth, concentration of malondialdehyde (MDA), hydrogen peroxide (H2O2), chlorophylls, flavonoids, carotenoids, phenolics, chlorophyll fluorescence and photosynthetic parameters were examined in leaves of Citrus aurantium L. plants. Exogenous application of Pb and Cu resulted in an increase in leaf H2O2 and lipid peroxidation (MDA). Toxicity symptoms of both Pb and Cu treated plants were stunted growth and decreased pigments concentration. Furthermore, photosynthetic activity of treated plants exhibited a significant decline. The inhibition of growth in Pb and Cu-treated plants was accompanied by oxidative stress, as indicated by the enhanced lipid peroxidation and the high H2O2 concentration. Furthermore, antioxidants in citrus plants after exposure to high Pb and Cu concentrations were significantly increased compared to control and low Pb and Cu treatments. In conclusion, this study indicates that Pb and Cu promote lipid peroxidation, disrupt membrane integrity, reduces growth and photosynthesis and inhibit mineral nutrition. Considering the potential for adverse human health effects associated with high concentrations of Pb and Cu contained in edible parts of citrus plants the study signals that it is important to conduct further research into the accessibility and uptake of the tested heavy metals in the soil and whether they pose risks to humans.

Background: Oxidative stress is a unified concept for the assessment of metabolic status of buffaloes affected by a cocktail of heavy metal exposure from environment and it may significantly affect the metabolic profile and milk production during summer season. The present study aimed at evaluation of effect of probiotic (Saccharomyces cerevisiae strain 1026) and amla powder (Embilica officinalis) supplementation on levels of heavy metals, antioxidant status, oxidative stress in lymphocytes, metabolic profile and milk production of summer stressed buffaloes exposed to environmental heavy metal pollution. Methods: Twenty summer stressed lactating Murrah buffaloes of the same age group, close parity and in early lactation from the heavy metal exposed area were divided into two groups: Control (without supplementation) and Treatment group (supplemented with Saccharomyces cerevisiae1026) @ 50 billion live cells / animal /day and Amla powder @ 86 mg/kg body weight for 30 days. Blood and milk samples were collected from both the groups on the day of starting of supplementation (i.e. day 0) and on there after days 15 and 30 and analyzed for antioxidant status, metabolic profile, milk yield and quality.Result: Oral supplementation of probiotic and amla powder for 30 days improved the antioxidant status, metabolic profile and milk production of summer stressed buffaloes residing in heavy metal exposed area. The percentage monetary gains from buffaloes fed probiotic and amla powder was 13.68% more as compared to control.
