Toxicity Mechanism And Health Effects Of Some Heavy Metals

Nov 15, 2014 Arsenic. Arsenic is one of the most important heavy metals causing disquiet from both ecological and individual health standpoints Hughes et al., 1988.It has a semimetallic property, is prominently toxic and carcinogenic, and is extensively available in the form of oxides or sulfides or as a salt of iron, sodium, calcium, copper, etc. Singh et al., 2007.

We have evidence that the intravenous infusion of sodium nitrite NaNO2 results in an antiarrhythmic effect when given 24 h prior to an ischemia and reperfusion IR insult in anaesthetized dogs. This protection was associated with the reduction of reactive oxygen species resulting from IR through the attenuation of mitochondrial respiration. Here, we examined whether the changes in calcium ...

Alkalinity And Hardness

Alkalinity and water hardness are fairly similar--essentially they both come from sources in nature. Water moves through rocks and picks up minerals as it does so on its way to rivers and lakes. When limestone and dolomite dissolve in water, one half of the molecule is calcium or magnesium the hardness and the other half is the carbonate ...
