Toxicity of nanosized and bulk ZnO, CuO and TiO2 to bacteria Vibrio fischeri and crustaceans Daphnia magna and Thamnocephalus platyurus.
TL;DR: This is the first evaluation of ZnO, CuO and TiO2 toxicity to bacteria Vibrio fischeri and crustaceans Daphnia magna and Thamnocephalus platyurus with a special emphasis on product formulations (nano or bulk oxides) and solubilization of particles.

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)
TL;DR: The effects of multiple heavy metal stress on the activity of antioxidative enzymes and lipid peroxidation were studied in leaves and roots of two mangrove plants and indicated that K. candel is more tolerant to heavy metals than B. gymnorrhiza, while POD activity in roots and leaves maybe serve as a biomarker of heavyMetal stress in K. Candel.

Antioxidant enzyme responses of plants to heavy metal stress
Anwesha M. Bhaduri,M. H. Fulekar +1 more
TL;DR: The aim of this review is to assemble the current understandings of role of antioxidant enzymes of plants subjected to heavy metal stress to result in developing plants that can overcome oxidative stress with the expression of antioxidants enzymes.

Gramine-induced growth inhibition, oxidative damage and antioxidant responses in freshwater cyanobacterium Microcystis aeruginosa.
TL;DR: The results suggested that the activation of antioxidants in M. aeruginosa played an important role to resist the stress from gramine at initial time, and the inactivation of SOD is crucial to the growth inhibition.
