chromium VI in cement
My name is Julien GUIGANTI and I am a french student. I need an information for a study about the worldwide chromium 6 use.
I send you this e-mail in order to know if countries except European ones have already adopted a law to limit the rate of chromium 6 in their cement?
If the answer is yes, can you describe me the law with the maximum authorized rate ?
If the answer is no, do you know if such a law is studied and when this law will probably be voted?
