Metallic compounds contribute to the oxidative stress of ambient particulate matter (PM)
exposure. The toxicity of redox inert ions of cadmium, mercury, lead and zinc, as well as …

Transition metal ions are key elements of various biological processes ranging from oxygen
formation to hypoxia sensing, and therefore, their homeostasis is maintained within strict …

Detailed studies in the past two decades have shown that redox active metals like iron (Fe),
copper (Cu), chromium (Cr), cobalt (Co) and other metals undergo redox cycling reactions …

Metals are involved in almost all aspects of human life today: some are essential for
maintenance of cell physiological activities and others are important industrial materials …

The role of reactive oxygen species, with the subsequent oxidative deterioration of biological
macromolecules in the toxicities associated with transition metal ions, is reviewed. Recent …

Toxic metals (lead, cadmium, mercury and arsenic) are widely found in our environment.
Humans are exposed to these metals from numerous sources, including contaminated air …

Metals can cause oxidative stress by increasing the formation of reactive oxygen species
(ROS), which make antioxidants incapable of defiance against growing amounts of free …

A range of epidemiological studies in the 1990s showed that exposure to ambient
particulate matter (PM) is associated with adverse health effects in the respiratory system …

Changes in the intracellular thiol–disulfide balance are considered major determinants in
the redox status/signaling of the cell. Cellular signaling is very sensitive to both exogenous …

Cadmium (Cd) is an environmental toxicant of public health significance worldwide. Diet is
the main Cd exposure source in the non-occupationally exposed and non-smoking …
