PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Cadmium effects

Heikki Savolainen   (2012-07-16 13:03)  Ministry of Social Affairs and Health, Tampere, Finland

Dear Editor,

This very comprehensive review summarizes cogently the large literature on the cadmium toxicity.

I would like to highlight one of the fundamental mechanisms of its toxicity which is its intereference with proteoglycan metabolism in lungs and in kidney. Consequently, the occupational exposure to cadmium fumes is associated with lung and kidney damage (1)

The effect on the urinary proteoglycans becomes apparent at the urinary Cd content of 3 ��g / g creatinine (2). This value is not much higher than detected in heavy smokers (upto 2 ��g/litre).
