Green isn't all that green after all
From the NY Times:
Take Pigment Green 7, the commonest shade of green used in plastics and paper. It is an organic pigment but contains chlorine, some forms of which can cause cancer and birth defects. Another popular shade, Pigment Green 36, includes potentially hazardous bromide atoms as well as chlorine; while inorganic Pigment Green 50 is a noxious cocktail of cobalt, titanium, nickel and zinc oxide.

Where would you go if you didn't live in U.S.A.?
Really, anywhere is nice.........just have that knife. :P
I don't suppose any of you guys remember the campaign to ban dihydrogen monoxide? Journalists take advantage of the fact that most people (except on this site) have never had a chemistry or statistics class. People without that knowledge can be easily frightened by words like "toxic" or the name of just about any element or chemical compound. Journalists are not bound by any regulation to tell the whole truth, just whatever parts of it they think will sell papers or get hits.
Now greenpeace is going to have to make their signs out of moss, LOL.
It's like trying to argue that you should use paper cups, because they break down quicker than porcelain coffee cups. It's ludicrous and idiotic.
Props, NYTimes.

A much more interesting question around these pigments is whether the heavy metals leach out of them (as the lead in lead paint can do), or whether they are sufficient bound chemically as to render them biologically inert.
The NY Times article does address the leaching of arsenic from ancient (18th Century) green wallpaper dye, but doesn't address the issue with current pigments.
The question about the heavy metals is much more interesting, it's true.
Reductio ad absurdum, since the conclusion is faulty, the input assumption (lack of relative risk assessment) must be faulty. So (speaking to the NY Times, not to you :-) give us better quantitative information on the relative risks and relative harm of these pigments compared to other things.
Oooh, sorry, I think my cynicism is showing...
And with classic paints it doesn't matter which colour it is really.
