Metal toxicity in plants is still a global problem for the environment, agriculture and ultimately
human health. This review initially addresses the current state of the environmental …

The purpose of this paper is to provide a brief review of the current knowledge regarding
metabolism and toxicity of copper and copper-based pesticides in living organisms. Copper …

Copper is an essential metal for normal plant growth and development, although it is also
potentially toxic. Copper participates in numerous physiological processes and is an …

Photoinhibition of photosystem II was studied in vivo with bean (Phaseolus vulgaris) plants
grown in the presence of 0.3 (control), 4, or 15 μm Cu2+. Although photoinhibition …

The targets of heavy metal (here Cu2+ and Zn2+) attack on the photosynthetic apparatus of
algae belonging to different phyla were investigated. Experiments with the green alga …

The effects of zinc on growth, mineral content, chlorophyll a fluorescence, and detoxifying
enzyme activity (ascorbate peroxidase (APX), EC 1.11. 1.11; superoxide dismutase (SOD) …

Nutritional micronutrient deficiencies and exposure to pollutant metals threaten human
health globally. Plant crops are at the beginning of a food chain that largely determines food …

There are 110 elements in the periodic table with the elements from 104 to 110 being of
somewhat recent discovery (www. sdfine. com). Of these chemical elements, metals make …

Many heavy metals inhibit electron transfer reactions in Photosystem II (PSII). Cd2+ is known
to exchange, with high affinity in a slow reaction, for the Ca2+ cofactor in the Ca/Mn cluster …

The role of reactive oxygen species (ROS) in copper (Cu) toxicity to two freshwater green
algal species, Pseudokirchneriella subcapitata (Korshikov) Hindák and Chlorella vulgaris …
